    - by rokdd
    Hi, I know that there are really a mass of XML XSLT php merging threads at SO. But php specific i could not found what might my problem: $xml = new DOMDocument; $xml-load("f.xml"); $xsl = new DOMDocument; $xsl-load('test.xsl'); // init and configure processor $proc = new XSLTProcessor; $proc-importStyleSheet($xsl); // import xsl document $xml2=$proc-transformToXML($xml); echo $xml2; My xslt file looks a bit empty.. However i tried ´output method="xml"´. but it doesnot help.. PHP returns always the data as text or html but not in XML.. what i am doing wrong. I only want to edit the XML with xslt and save back to XML (file). THanks for your help!

  • How to set icon to title bar for each Activity in Tablelayout in android

    - by Venu Gopal
    In my tablayout example, i have created 3 tabs, as usually i set 3 activities for each tab. I can set image to title bar of activity, which adds the intent to each tab. Due to this, the image in the title bar is visible in all 3 tabs. My requirement is to set a different image to title bar for each activity. I followed this to set image to title bar. But when i am going to do the same thing to each activity, getting android.util.AndroidRuntimeException: You cannot combine custom titles with other title features this error and application is terminated. manifest.xml <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.aptitsolution.tablayout" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name" android:theme="@style/MyTheme"> <activity android:name=".TabLayoutDemo" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name="AlbumsActivity"></activity> <activity android:name="ArtistsActivity"></activity> <activity android:name="SongsActivity"></activity> TabLayoutDemo.java public class TabLayoutDemo extends TabActivity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_CUSTOM_TITLE); setContentView(R.layout.main); getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.my_title); Resources res = getResources(); // Resource object to get Drawables TabHost tabHost = getTabHost(); // The activity TabHost TabHost.TabSpec spec; // Resusable TabSpec for each tab Intent intent; // Reusable Intent for each tab // Create an Intent to launch an Activity for the tab (to be reused) intent = new Intent().setClass(this, ArtistsActivity.class); // Initialize a TabSpec for each tab and add it to the TabHost spec = tabHost.newTabSpec("artists").setIndicator("Artists", res.getDrawable(R.drawable.ic_tab_artists)) .setContent(intent); tabHost.addTab(spec); .... ....

  • XML problem in the basic menu example

    - by arakn0
    Hi there, I am trying to create an app with some menus, an I am following the basic example available in the official android site: http://developer.android.com/guide/topics/ui/menus.html My problems appear when I define the menu in the XML. After creating the folder res/menu and creating the menu_option.xml file from eclipse.... The project (in general) gives an error that can be read from the Problems tab: Unparsed aapt error(s)! Check the console for output Android Packaging Problem So, changing to the Console tab to get more information about the problem, this can be read: [2010-06-02 11:35:54 - TestAudio] Error in an XML file: aborting build. [2010-06-02 11:35:54 - TestAudio] W/ResourceType(11566): Bad XML block: header size 63327 or total size -144759824 is larger than data size 0 [2010-06-02 11:35:54 - TestAudio] /home/User/workspace/TestAudio/res/menu/options_menu.xml:1: error: Error parsing XML: no element found The strange thing is that eclipse recognizes the menu items that I've defined in the XML,I can reference them in the code with no problems and my main activity builds. (and the rest of the files too). Could it be that when eclipse creates a file, for some reason, the Android SDK has problems to read it, or something similar?? The XML code is exactly the same as the one in the example, so I don't really know what is happening. The code in options_menu.xml is this: <menu xmlns:android="http://schemas.android.com/apk/res/android" <item android:id="@+id/new_game" android:title="New Game" / <item android:id="@+id/quit" android:title="Quit" / </menu Thanks in advance for your help!

  • How to parse the AndroidManifest.xml file inside an .apk package

    - by jnorris
    This file appears to be in a binary XML format. What is this format and how can it be parsed programmatically (as opposed to using the aapt dump tool in the SDK)? This binary format is not discussed in the in the documentation here: http://developer.android.com/guide/topics/manifest/manifest-intro.html Note: I want to access this information from outside the Android environment, preferably from Java.

  • Switching to landscape mode in Android Emulator

    - by Cody
    This is probably a pretty easy to answer question, but I can't find the solution myself after a couple hours of searching the documentation and Google. I set the orientation of my Android app to landscape in the AndroidManifest.xml file: android:screenOrientation="landscape" However, when I run the app in the simulator, it appears sideways and in portrait mode. How can I switch the emulator to landscape mode on a mac? It's running the 1.6 SDK. Thanks!

  • Cannot use standard android color attribute in custom color selector

    - by Manish Gupta
    So, android defines the following in themes.xml: <style name="Theme"> ... <item name="colorPressedHighlight">@color/legacy_pressed_highlight</item> </style> and: <style name="Theme.Holo"> ... <item name="colorPressedHighlight">@color/holo_blue_light</item> </style> I want to use this colorPressedHighlight as the background color for my custom Button when it is pressed. So I defined the following in res/color/app_button_background.xml: <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android" > <item android:state_pressed="true" android:drawable="?android:colorPressedHighlight"/> <item android:drawable="@android:color/transparent" /> </selector> Finally, I define my custom ImageButton style: <style name="App_ImageButtonStyle" parent="@android:style/Widget.ImageButton"> <item name="android:gravity">center</item> <item name="android:background">@color/app_button_background</item> </style> I crash on app launch with the following call stack: 06-27 20:24:41.954: E/AndroidRuntime(532): Caused by: org.xmlpull.v1.XmlPullParserException: Binary XML file line #6: <item> tag requires a 'drawable' attribute or child tag defining a drawable 06-27 20:24:41.954: E/AndroidRuntime(532): at android.graphics.drawable.StateListDrawable.inflate(StateListDrawable.java:178) 06-27 20:24:41.954: E/AndroidRuntime(532): at android.graphics.drawable.Drawable.createFromXmlInner(Drawable.java:867) 06-27 20:24:41.954: E/AndroidRuntime(532): at android.graphics.drawable.Drawable.createFromXml(Drawable.java:804) 06-27 20:24:41.954: E/AndroidRuntime(532): at android.content.res.Resources.loadDrawable(Resources.java:1920) I know that directly accessing @color/legacy_pressed_highlight or @color/holo_blue_light instead of accessing them through the colorPressedHighlight fixes the crash but it does not solve the problem. Themes can vary, hence I need to access it through the colorPressedHighlight attribute. PS: I had a similar problem to which I haven't found an answer yet. Can someone please help!

  • Why do I get a null pointer exception from TabWidget?

    - by rushinge
    I'm writing an android program in which I have an activity that uses tabs. The Activity public class UnitActivity extends TabActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TabHost tabHost = getTabHost(); TabSpec spec; Resources res = getResources(); LayoutInflater.from(this).inflate(R.layout.unit_view, tabHost.getTabContentView(), true); spec = tabHost.newTabSpec("controls"); spec.setIndicator("Control", res.getDrawable(R.drawable.ic_tab_equalizer)); spec.setContent(R.id.txtview); tabHost.addTab(spec); } } The XML referenced by R.layout.unit_view <?xml version="1.0" encoding="utf-8"?> <TabHost xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="5dp"> <TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="wrap_content"/> <FrameLayout android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="5dp"> <TextView android:id="@+id/txtview" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="bottom" android:text="nullpointer this!" /> </FrameLayout> </LinearLayout> </TabHost> As far as I can see I'm doing the same thing I see in the tabs1 api sample from the android sdk. I've tried "getLayoutInflator()" instead of "LayoutInflator.from(this)" with the same result. If I replace the LayoutInflater line with "setContentView(R.layout.unit_view)" my program doesn't crash with a null pointer exception but my content is completely blank and empty. I get the tab and that's it. I've checked to make sure R.layout.unit_view and tabHost are not null when it runs the LayoutInflater line and they seem to be fine. They're defenitely not null. I've also checked to make sure LayoutInflater.from(this) returns a valid layout inflater object and it does. The logcat indicating the error says E/AndroidRuntime( 541): java.lang.NullPointerException E/AndroidRuntime( 541): at android.widget.TabWidget.dispatchDraw(TabWidget.java:206) E/AndroidRuntime( 541): at android.view.ViewGroup.drawChild(ViewGroup.java:1529) E/AndroidRuntime( 541): at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1258) E/AndroidRuntime( 541): at android.view.ViewGroup.drawChild(ViewGroup.java:1529) E/AndroidRuntime( 541): at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1258) E/AndroidRuntime( 541): at android.view.ViewGroup.drawChild(ViewGroup.java:1529) E/AndroidRuntime( 541): at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1258) E/AndroidRuntime( 541): at android.view.ViewGroup.drawChild(ViewGroup.java:1529) E/AndroidRuntime( 541): at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1258) E/AndroidRuntime( 541): at android.view.ViewGroup.drawChild(ViewGroup.java:1529) E/AndroidRuntime( 541): at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1258) E/AndroidRuntime( 541): at android.view.ViewGroup.drawChild(ViewGroup.java:1529) E/AndroidRuntime( 541): at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1258) E/AndroidRuntime( 541): at android.view.View.draw(View.java:6538) E/AndroidRuntime( 541): at android.widget.FrameLayout.draw(FrameLayout.java:352) E/AndroidRuntime( 541): at android.view.ViewGroup.drawChild(ViewGroup.java:1531) E/AndroidRuntime( 541): at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1258) E/AndroidRuntime( 541): at android.view.ViewGroup.drawChild(ViewGroup.java:1529) E/AndroidRuntime( 541): at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1258) E/AndroidRuntime( 541): at android.view.View.draw(View.java:6538) E/AndroidRuntime( 541): at android.widget.FrameLayout.draw(FrameLayout.java:352) E/AndroidRuntime( 541): at com.android.internal.policy.impl.PhoneWindow$DecorView.draw(PhoneWindow.java:1830) E/AndroidRuntime( 541): at android.view.ViewRoot.draw(ViewRoot.java:1349) E/AndroidRuntime( 541): at android.view.ViewRoot.performTraversals(ViewRoot.java:1114) E/AndroidRuntime( 541): at android.view.ViewRoot.handleMessage(ViewRoot.java:1633) E/AndroidRuntime( 541): at android.os.Handler.dispatchMessage(Handler.java:99) E/AndroidRuntime( 541): at android.os.Looper.loop(Looper.java:123) E/AndroidRuntime( 541): at android.app.ActivityThread.main(ActivityThread.java:4363) E/AndroidRuntime( 541): at java.lang.reflect.Method.invokeNative(Native Method) E/AndroidRuntime( 541): at java.lang.reflect.Method.invoke(Method.java:521) E/AndroidRuntime( 541): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:860) E/AndroidRuntime( 541): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:618) E/AndroidRuntime( 541): at dalvik.system.NativeStart.main(Native Method) I/Process ( 61): Sending signal.

My actual program is more complex and has more than one tab but I simplified it down to this in an attempt to find out why it's crashing but it still crashes and I don't know why. If I don't use LayoutInflator my program doesn't crash but I don't get any content either, just tabs.

  • log4j support in Android

    - by Travis
    I am attempting to shoehorn an existing SDK onto an android device and one of the dependencies of said SDK is Apache log4j. I am able to load my test program onto the android emulator but when the log4j object "PropertySetter" is called the program fails with a verification exception. Is there a way to ameliorate this issue?

  • Perl XML SAX parser emulating XML::Simple record for record

    - by DVK
    Short Q summary: I am looking a fast XML parser (most likely a wrapper around some standard SAX parser) which will produce per-record data structure 100% identical to those produced by XML::Simple. Details: We have a large code infrastructure which depends on processing records one-by-one and expects the record to be a data structure in a format produced by XML::Simple since it always used XML::Simple since early Jurassic era. An example simple XML is: <root> <rec><f1>v1</f1><f2>v2</f2></rec> <rec><f1>v1b</f1><f2>v2b</f2></rec> <rec><f1>v1c</f1><f2>v2c</f2></rec> </root> And example rough code is: sub process_record { my ($obj, $record_hash) = @_; # do_stuff } my $records = XML::Simple->XMLin(@args)->{root}; foreach my $record (@$records) { $obj->process_record($record) }; As everyone knows XML::Simple is, well, simple. And more importantly, it is very slow and a memory hog - due to being a DOM parser and needing to build/store 100% of data in memory. So, it's not the best tool for parsing an XML file consisting of large amount of small records record-by-record. However, re-writing the entire code (which consist of large amount of "process_record"-like methods) to work with standard SAX parser seems like an big task not worth the resources, even at the cost of living with XML::Simple. What I'm looking for is an existing module which will probably be based on a SAX parser (or anything fast with small memory footprint) which can be used to produce $record hashrefs one by one based on the XML pictured above that can be passed to $obj->process_record($record) and be 100% identical to what XML::Simple's hashrefs would have been. I don't care much what the interface of the new module is - e.g whether I need to call next_record() or give it a callback coderef accepting a record.

  • Reading Resource Files from my own APK in Android Native Environment

    - by Kyle
    I'm porting to Android. My existing project has a ton of resource files that I'm porting into my Android project. I have them all in /res/raw/, and I would like to access those resources in my native library with functions such as fopen() and such. Can this be done, or do I have to go through JNI for this as well? I would really prefer not to, for ease of porting and possible speed and memory reasons.

  • Register filetype with the browser?

    - by Lord.Quackstar
    In Android, I am trying to make it so that the user downloads a font from the browser, and I am able to view the font when downloaded. After multiple issues, I still have one lingering one: Registering the filetype with the browser. When trying to download with the Emulator (2.1-u1), I get "Cannot download. The content is not supported on this phone". Okay, so maybe its my manifest file. Updated with this: <activity android:name=".MainActivity" android:label="MainActivity"> <intent-filter> <action android:name="android.intent.action.MAIN"/> <category android:name="android.intent.category.LAUNCHER"/> <catagory android:name="android.intent.category.BROWSABLE"/> <data android:scheme="http"/> <data android:scheme="https"/> <data android:scheme="ftp"/> <data android:host="*"/> <data android:mimeType="*/*"/> <data android:pathPattern=".*zip"/> </intent-filter> </activity> Went back to the browser, and fails again. Restart the Emulator, still fails. Note that I got this format from posts here. Any suggestions on what to do?

  • GoogleTv video using VideoView is clipped, even though its in a separate layout of its own

    - by MYR
    Wrote an application for GoogleTV box to play a video. The video is a separate activity to the main activity. Wired up a button on my main layout/activity to to start the video activity up (using its own video.xml layout), the video activity loads and starts playing, but the video is clipped, only showing a few centimetres of the bottom. The clipped region looks like the views that occupied the previous layout (main.xml) . The intriguing thing is that if I push the back button, before returning to the main activity the full video frame is shown. Not sure what I am doing wrong here. Any suggestions welcome. Code: main.xml <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <TextView android:id="@+id/hello_message" android:layout_width="fill_parent" android:layout_height="200dp" android:gravity="center" android:text="@string/hello_message" android:textSize="78sp" /> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" > <EditText android:id="@+id/edit_message" android:layout_width="0dip" android:layout_height="wrap_content" android:layout_weight="1" android:ems="10" android:hint="@string/edit_message" > <requestFocus /> </EditText> <Button android:id="@+id/button_send" android:layout_width="wrap_content" android:layout_height="wrap_content" android:onClick="displayMessage" android:text="@string/button_send" /> <Button android:id="@+id/button_send_a" android:layout_width="wrap_content" android:layout_height="wrap_content" android:onClick="sendMesssage" android:text="@string/button_send_a" /> </LinearLayout> <Button android:id="@+id/videobutton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:onClick="startAVideo" android:text="Video Player" /> </LinearLayout> GoogleTVExActivity.java (excerpt): ... public class GoogleTVExActivity extends Activity { public final static String EXTRA_MESSAGE = "uk.co.bbc.googletvex.MESSAGE"; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } public void displayMessage(View view) { TextView t = (TextView)findViewById(R.id.hello_message); EditText e =(EditText) findViewById(R.id.edit_message); t.setText(e.getText().toString()); e.setText(""); } public void sendMesssage(View view) { Intent intent = new Intent(this, DisplayMessageActivity.class); EditText editText = (EditText) findViewById(R.id.edit_message); String message = editText.getText().toString(); intent.putExtra(EXTRA_MESSAGE, message); startActivity(intent); } public void startAVideo(View view) { Intent intent = new Intent(this, VideoViewActivity.class); startActivity(intent); } } video.xml: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <VideoView android:id="@+id/myvideoview" android:layout_width="fill_parent" android:layout_height="fill_parent" /> </LinearLayout> VideoViewActivity.java (excerpt) ... import android.app.Activity; import android.net.Uri; import android.os.Bundle; import android.widget.MediaController; import android.widget.VideoView; public class VideoViewActivity extends Activity { String SrcPath = "rtsp://v5.cache1.c.youtube.com/CjYLENy73wIaLQnhycnrJQ8qmRMYESARFEIJbXYtZ29vZ2xlSARSBXdhdGNoYPj_hYjnq6uUTQw=/0/0/0/video.3gp"; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.video); VideoView myVideoView = (VideoView)findViewById(R.id.myvideoview); myVideoView.setVideoURI(Uri.parse(SrcPath)); myVideoView.setMediaController(new MediaController(this)); myVideoView.requestFocus(); myVideoView.start(); } }

  • ListView not showing up in fragment

    - by aindurti
    When I insert a listview in a fragment in my application, it doesn't show up after I populate it with items. In fact, the application crashes due to a NullPointerException. Can anybody help me? Here is the detail activity from which I show the fragments. package com.example.sample; import android.content.Intent; import android.os.Bundle; import android.support.v4.app.Fragment; import android.support.v4.app.FragmentTransaction; import android.support.v4.app.NavUtils; import android.widget.ArrayAdapter; import android.widget.ListView; import com.actionbarsherlock.app.ActionBar; import com.actionbarsherlock.app.ActionBar.Tab; import com.actionbarsherlock.app.SherlockFragmentActivity; import com.actionbarsherlock.view.MenuItem; /** * An activity representing a single Course detail screen.

ActionBar actionBar = getSupportActionBar(); actionBar.setDisplayHomeAsUpEnabled(true); actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); // initiating both tabs and set text to it. ActionBar.Tab assignTab = actionBar.newTab().setText("Assignments"); ActionBar.Tab schedTab = actionBar.newTab().setText("Schedule"); ActionBar.Tab contactTab = actionBar.newTab().setText("Contact"); // Create three fragments to display content Fragment assignFragment = new Assignments(); Fragment schedFragment = new Schedule(); Fragment contactFragment = new Contact(); assignTab.setTabListener(new MyTabsListener(assignFragment)); schedTab.setTabListener(new MyTabsListener(schedFragment)); contactTab.setTabListener(new MyTabsListener(contactFragment)); actionBar.addTab(assignTab); actionBar.addTab(schedTab); actionBar.addTab(contactTab); ListView listView = (ListView) findViewById(R.id.assignlist); String[] values = new String[] { "Android", "iPhone", "WindowsMobile", "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X", "Linux", "OS/2" }; // First paramenter - Context // Second parameter - Layout for the row // Third parameter - ID of the TextView to which the data is written // Forth - the Array of data ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, android.R.id.text1, values); // Assign adapter to ListView listView.setAdapter(adapter); } @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case android.R.id.home: // This ID represents the Home or Up button.

  • How to get ImageButton size within Android GridView?

    - by wufoo
    I'm subclassing ImageButton in order to draw lines on it and trying to figure out where the actual button coordinates are within my gridview. I am using onGlobalLayout to setup Top, Bottom, Right and Left, but these seem to be for the actual "square" within the grid, and not the actual button (see image). The purple lines are drawn in myImageButton.onDraw() using coords gathered from myImageButton.onGlobalLayout(). I thought these would be for the button, but they seem to be from something else. Not sure what. I'd like the purple lines to match the outline of the button so the lines I draw appear on the button and not just floating out in the LinearLayout somewhere. The light blue is the background color of the vertical LinearLayout holding the Textview (for the number) and myImageButton. Any way to get the actual button size? XML Layout: <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/lay_cellframe" android:layout_width="fill_parent" android:layout_height="fill_parent" > <LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="fill_vertical|fill_horizontal" android:orientation="vertical" > <TextView android:id="@+id/tv_cell" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_margin="2dp" android:gravity="center" android:text="TextView" android:textSize="10sp" /> <com.example.icaltest2.myImageButton android:id="@+id/imageButton1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_gravity="center" android:layout_margin="0dp" android:adjustViewBounds="false" android:background="@android:drawable/btn_default" android:scaleType="fitXY" android:src="@android:color/transparent" /> </LinearLayout> </FrameLayout> myImageButton.java public myImageButton (Context context, AttributeSet attrs) { super (context, attrs); mBounds = new Rect(); ViewTreeObserver vto = this.getViewTreeObserver (); vto.addOnGlobalLayoutListener (ogl); Log.d (TAG, "myImageButton"); } ... OnGlobalLayoutListener ogl = new OnGlobalLayoutListener() { @Override public void onGlobalLayout () { Rect b = getDrawable ().getBounds (); mBtnTop = b.centerY () - (b.height () / 2); mBtnBot = b.centerY () + (b.height () / 2); mBtnLeft = b.centerX () - (b.width () / 2); mBtnRight = b.centerX () + (b.width () / 2); } }; ... @Override protected void onDraw (Canvas canvas) { super.onDraw (canvas); Paint p = new Paint (); p.setStyle (Paint.Style.STROKE); p.setStrokeWidth (1); p.setColor (Color.MAGENTA); canvas.drawCircle (mBtnLeft, mBtnTop, 2, p); canvas.drawCircle (mBtnLeft, mBtnBot, 2, p); canvas.drawCircle (mBtnRight, mBtnTop, 2, p); canvas.drawCircle (mBtnRight, mBtnBot, 2, p); canvas.drawRect (mBtnLeft, mBtnTop, mBtnRight, mBtnBot, p); }

  • stdexcept On Android

    - by David R.
    I'm trying to compile SoundTouch on Android. I started with this configure line: ./configure CPPFLAGS="-I/Volumes/android-build/mydroid/development/ndk/build/platforms/android-3/arch-arm/usr/include/" LDFLAGS="-Wl,-rpath-link=/Volumes/android-build/mydroid/development/ndk/build/platforms/android-3/arch-arm/usr/lib -L/Volumes/android-build/mydroid/development/ndk/build/platforms/android-3/arch-arm/usr/lib -nostdlib -lc" --host=arm-eabi --enable-shared=yes CFLAGS="-nostdlib -O3 -mandroid" host_alias=arm-eabi --no-create --no-recursion Because the Android NDK targets ARM, I also had to change the Makefile to remove the -msse2 flags to progress. When I run 'make', I get: /bin/sh ../../libtool --tag=CXX --mode=compile arm-eabi-g++ -DHAVE_CONFIG_H -I. -I../../include -I../../include -I/Volumes/android-build/mydroid/development/ndk/build/platforms/android-3/arch-arm/usr/include/ -O3 -fcheck-new -I../../include -g -O2 -MT FIRFilter.lo -MD -MP -MF .deps/FIRFilter.Tpo -c -o FIRFilter.lo FIRFilter.cpp libtool: compile: arm-eabi-g++ -DHAVE_CONFIG_H -I. -I../../include -I../../include -I/Volumes/android-build/mydroid/development/ndk/build/platforms/android-3/arch-arm/usr/include/ -O3 -fcheck-new -I../../include -g -O2 -MT FIRFilter.lo -MD -MP -MF .deps/FIRFilter.Tpo -c FIRFilter.cpp -o FIRFilter.o FIRFilter.cpp:46:21: error: stdexcept: No such file or directory FIRFilter.cpp: In member function 'virtual void soundtouch::FIRFilter::setCoefficients(const soundtouch::SAMPLETYPE*, uint, uint)': FIRFilter.cpp:177: error: 'runtime_error' is not a member of 'std' FIRFilter.cpp: In static member function 'static void* soundtouch::FIRFilter::operator new(size_t)': FIRFilter.cpp:225: error: 'runtime_error' is not a member of 'std' make[2]: *** [FIRFilter.lo] Error 1 make[1]: *** [all-recursive] Error 1 make: *** [all-recursive] Error 1 This isn't very surprising, since the -nostdlib flag was required. Android seems to have neither stdexcept nor stdlib. How can I get past this block of compiling SoundTouch? At a guess, there may be some flag I don't know about that I should use. I could refactor the code not to use stdexcept. There may be a way to pull in the original stdexcept source and reference that. I might be able to link to a precompiled stdexcept library.

  • Method for launching audio player on Android from web page for streaming media

    - by Brad
    To link to SHOUTcast/HTTP internet radio streams, traditionally you would link to a playlist file, such as an M3U or PLS. From there, the browser would launch the audio player registered to handle the playlist. This works great on any PC, Palm, Blackberry, and iPhone. This method does not work in Android without installing extra software. Sure, Just Playlists or StreamFurious can handle it just fine, but I am assuming there has to be a way to invoke the audio or video player commonly installed by default on Android installations. By default, no audio player is capable of handling M3U or PLS. The player seems to open it, but says "Unsupported Media Type". To make this more annoying, the browser is capable of streaming MP3 audio over HTTP, simply by opening a link to an MP3 file. I have tried simply linking directly to the MP3 stream hosted by SHOUTcast, which should end up in the same result, but SHOUTcast detects "Mozilla" in the user-agent string, and instead of sending the stream, it sends the information page for the station. How should I link to a SHOUTcast stream on Android, from a normal mobile site, without using extra applications?

    The subject says it all. My application gets internet access thanks to the android.permission.INTERNET permission, but my test cases don't while using the instrumentation test runner. This means I can't test my server IO routines in my test cases. What's up? Here's my manifest in case it helps you. Thanks! Sorry about the lack of indents - could not get it working on short notice with this site. Thanks! <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.helloandroid" android:versionCode="1" android:versionName="1.0"> <uses-permission android:name="android.permission.INTERNET"></uses-permission> <application android:icon="@drawable/icon" android:label="@string/app_name"> <uses-library android:name="android.test.runner" /> <activity android:name=".HelloAndroid" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> <uses-sdk android:minSdkVersion="2" /> <instrumentation android:name="android.test.InstrumentationTestRunner" android:targetPackage="qnext.mobile.redirect" android:label="Qnext Redirect Tests" /> </manifest>

  • Do not get the rootLayoutContainer in a Fragment (Android 3.0 Preview)

    - by Hawk66
    Hello, I'm currently getting into the fragment API of the Android 3.0 Preview and have built the following minimal coding: I have an Activty, which shall embed Fragment(s), which is currently implemented like this: public class Cockpit extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.cockpit); } public static class InfoFragment extends Fragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // Inflate the layout for this fragment ViewGroup infoFragmentRoot = (ViewGroup) getActivity().findViewById( R.id.infoFragmentRoot) ; return inflater.inflate(R.id.infoFragment, container, false); } } } The corresponding layout of the activity: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <fragment android:name="test.android.ui.cockpit.Cockpit$InfoFragment" android:id="@+id/infoFragment" android:layout_weight="1" android:layout_width="10dp" android:layout_height="match_parent" > <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:padding="12dp" android:id="@+id/infoFragmentRoot" > <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" /> </LinearLayout> </fragment> Now, I do not understand why the ViewGroup container in the onCreateView() in the internal class InfoFragment is a nullpointer, nor do I understand, why ViewGroup infoFragmentRoot = (ViewGroup) getActivity().findViewById( R.id.infoFragmentRoot) ; returns also null. Thanks for feedback.

  • Android: How to set the maximum size of a Spinner?

    - by Epaga
    Here is my layout <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:id="@+id/LinearLayout01" android:layout_height="wrap_content"> <Spinner android:text="@+id/AutoCompleteTextView01" android:id="@+id/Spinner01" android:layout_width="wrap_content" android:layout_height="wrap_content" android:width="130dp"></Spinner> <EditText android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/Chapter" android:width="30dp"></EditText> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/TextView01" android:text=":"></TextView> <EditText android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/Verse" android:width="40dp"></EditText> </LinearLayout> I inflate this layout as an AlertDialog's view. But when I pick a large element, the text fields get pushed out to the right. Is there any way to set the maximum size of the spinner so after choosing an element, it shortens the choice with an ellipsis ("...") or something?

  • Network Data Packet connectivity intent

  • Loading class instance from XML with Texture2D

    - by Thegluestickman
    I'm having trouble with XML and XNA. I want to be able to load weapon settings through XML to make my weapons easier to make and to have less code in the actual project file. So I started out making a basic XML document, something to just assign variables with. But no matter what I changed it gave me a new error every time. The code below gives me a "XML element 'Tag' not found", I added and it started to say the variables weren't found. What I wanted to do in the XML file as well, was load a texture for the file too. So I created a static class to hold my texture values, then in the Texture tag of my XML document I would set it to that instance too. I think that's were the problems are occuring because that's where the "XML element 'Tag' not found" error is pointing me too. My XML document: <XnaContent> <Asset Type="ConversationEngine.Weapon"> <weaponStrength>0</weaponStrength> <damageModifiers>0</damageModifiers> <speed>0</speed> <magicDefense>0</magicDefense> <description>0</description> <identifier>0</identifier> <weaponTexture>LoadWeaponTextures.ironSword</weaponTexture> </Asset> </XnaContent> My Class to load the weapon XML: public class Weapon { public int weaponStrength; public int damageModifiers; public int speed; public int magicDefense; public string description; public string identifier; public Texture2D weaponTexture; } public static class LoadWeaponXML { static Weapon Weapons; public static Weapon WeaponLoad(ContentManager content, int id) { Weapons = content.Load<Weapon>(@"Weapons/" + id); return Weapons; } } public static class LoadWeaponTextures { public static Texture2D ironSword; public static void TextureLoad(ContentManager content) { ironSword = content.Load<Texture2D>("Sword"); } } I'm not entirely sure if you can load textures through XML, but any help would be greatly appreciated.
