• Android Programming: Stay with CyanogenMod?

  - by Android Eve

  My new Nexus One came pre-installed with CyanogenMod. It's great so far, but since I bought it for software development purposes (initially just learning how to program for Android), should I stay with it, or install the official Android OS? If the latter, 2.2 or 2.3? My main concern is compatibility issues with documented API, that is wasting time on debugging problems that shouldn't have been there in the first place.

• Why Bluetooth needs DBUS way of communication in android?

  - by Rajesh SO

  I am newbie to Android DBUS, recently I was informed that I need to use DBUS to implement Bluetooth in Android, from DBUS documentation I see DBUS is used for communication medium between two applications. In Android apps -apps communication is through intents, if so why do we need DBUS for Bluetooth ? Is that DBUS serves as communication medium for networking (IP) between two apps since it is built over sockets? Please correct me if my understanding is wrong, any more information on DBUS along with Bluetooth implementation in Android is appreciated. Thanks.

• android error NoSuchElementException

  - by Alexander

  I have returned a cursor string but it contains a delimiter. The delimiter is . I have the string quest.setText(String.valueOf(c.getString(1)));I want to turn the into a new line. What is the best method to achieve this task in android. I understand there is a way to get the delimeter. I want this to achieved for each record. I can itterate through record like so. Cursor c = db.getContact(2); I tried using a string tokenizer but it doesnt seem to work. Here is the code for the tokenizer. I tested it in just plain java and it works without errors. String question = c.getString(1); // quest.setText(String.valueOf(c.getString(1))); //quest.setText(String.valueOf(question)); StringTokenizer st = new StringTokenizer(question,"<ENTER>"); //DisplayContact(c); // StringTokenizer st = new StringTokenizer(question, "=<ENTER>"); while(st.hasMoreTokens()) { String key = st.nextToken(); String val = st.nextToken(); System.out.println(key + "\n" + val); } I then tried running it in android. Here is the error log 06-06 22:31:55.251: E/AndroidRuntime(537): FATAL EXCEPTION: main 06-06 22:31:55.251: E/AndroidRuntime(537): java.util.NoSuchElementException 06-06 22:31:55.251: E/AndroidRuntime(537): at java.util.StringTokenizer.nextToken(StringTokenizer.java:208) 06-06 22:31:55.251: E/AndroidRuntime(537): at alex.android.test.database.quiz.TestdatabasequizActivity$1.onClick(TestdatabasequizActivity.java:95) 06-06 22:31:55.251: E/AndroidRuntime(537): at android.view.View.performClick(View.java:3511) 06-06 22:31:55.251: E/AndroidRuntime(537): at android.view.View$PerformClick.run(View.java:14105) 06-06 22:31:55.251: E/AndroidRuntime(537): at android.os.Handler.handleCallback(Handler.java:605) 06-06 22:31:55.251: E/AndroidRuntime(537): at android.os.Handler.dispatchMessage(Handler.java:92) 06-06 22:31:55.251: E/AndroidRuntime(537): at android.os.Looper.loop(Looper.java:137) 06-06 22:31:55.251: E/AndroidRuntime(537): at android.app.ActivityThread.main(ActivityThread.java:4424) 06-06 22:31:55.251: E/AndroidRuntime(537): at java.lang.reflect.Method.invokeNative(Native Method) 06-06 22:31:55.251: E/AndroidRuntime(537): at java.lang.reflect.Method.invoke(Method.java:511) 06-06 22:31:55.251: E/AndroidRuntime(537): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:784) 06-06 22:31:55.251: E/AndroidRuntime(537): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:551) 06-06 22:31:55.251: E/AndroidRuntime(537): at dalvik.system.NativeStart.main(Native Method) This is the database query public Cursor getContact(long rowId) throws SQLException { Cursor mCursor = db.query(true, DATABASE_TABLE, new String[] {KEY_ROWID, question, possibleAnsOne,possibleAnsTwo, possibleAnsThree,realQuestion,UR}, KEY_ROWID + "=" + rowId, null, null, null, null, null); if (mCursor != null) { mCursor.moveToFirst(); }

• Android OS 2.2 Permissions: I have absolutely no idea why this simple piece of code doesn't work. Wh

  - by Kevin

  I'm just playing around with some code. I create an Activity and simply do something like this: long lo = currentTimeMillis(); System.out.println(lo); lo *= 3; System.out.println(lo); SystemClock.setCurrentTimeMillis(lo); System.out.println( currentTimeMillis() ); Yes, in my AndroidManifest.xml, I've added: <uses-permission android:name="android.permission.SET_TIME"></uses-permission> <uses-permission android:name="android.permission.SET_TIME_ZONE"></uses-permission> Nothing changes. The SystemClock is never reset...it just keeps on ticking. The error that I'm getting just says that the permission "SET_TIME" was not granted to the program. Protection level 3. The permissions are there...and in the API for 2.2 it says that this feature is supported now. I have no idea what I'm doing wrong. If android.content.Intent; comes into play, please explain. I don't really understand what the idea behind intents! Thanks for any help!

• Is it possible to set an android icon from a drawable in a separate jar?

  - by Rpond

  I want to set a menu option icon for a drawable that is in another jar inside an xml file. <item android:id="@+id/my_location" android:title="My Location" android:icon="@+drawable/my_location"> Instead of drawable/my_location have something like com.somelib.R.drawable.someDrawable. I can set this in onCreateOptionsMenu but was just wondering if it could be done via the xml file.

• How can I tell if the screen is on in android?

  - by user297020

  In Android 2.2 (Level 7) the function PowerManager.IsScreenOn() returns a boolean that is true if the screen is turned on and false if the screen is turned off. I am developing code for Android 1.5 (Level 3). How do I accomplish the same task in older versions of Android? I do not want to turn the screen on or off in my code. I just want to know what it is.

• How big can I make an Android application's canvas in terms of pixels?

  - by user279112

  I've determined an estimate of the size of my Android emulator's screen in pixels, although I think its resolution can be changed to other numbers. Quite frankly though that doesn't eliminate the general problem of not knowing how many pixels on each axis I have to work with on my Android applications in general. The main problem I'm trying to solve is this: How do I make sure I don't use a faulty resolution on Android applications if I want to keep things' sizes constant (so that if the application screen shrinks, for instances, objects will still show up just as big - there just won't be as many of them being shown) if I wish to do this with a single universal resolution for each program? Failing that, how do I make sure everything's alright if I try to do everything the same way with maybe a few different pre-set resolutions? Mainly it seems like a relevant question that must be answered before I can come across a complete answer for the general problem is how big can I always make my application in pixels, NOT regarding if and when a user resizes the application's screen to something smaller than the maximum size permitted by the phone and its operating system. I really want to try to keep this simple. If I were doing this for a modern desktop, for instance, I know that if I design the application with a 800x600 canvas, the user can still shrink the application to the point they're not doing themselves any favors, but at least I can basically count on it working right and not being too big for the monitor or something. Is there such a magic resolution for Android, assuming that I'm designing for API levels 3+ (Android 1.5+)? Thanks

• How to refresh a fragment in a viewpager?

  - by aut_silvia

  I know there are already some questions to this problem. But I am really new in Android and ecspecially to Fragments and Viewpager. Pls have passion with me. I didn't found a answer which fits to my code. I dont know how to refresh a fragment or reload it when it's "active" again. TabsPagerAdapter.java: public class TabsPagerAdapter extends FragmentPagerAdapter{ public TabsPagerAdapter(FragmentManager fm){ super(fm); } @Override public Fragment getItem(int index) { switch (index) { case 0: return new KFZFragment(); case 1: return new LogFragment(); case 2: return new TrackFragment(); } return null; } @Override public int getCount() { // get item count - equal to number of tabs return 3; } } I have this 3 Fragments (KFZFragment,LogFragment,TrackFragment) and on the TrackFragment I calculate some data and this data should be display in a ListView in LogFragment. But when I change to LogFragment it's not the latest data. So it doesnt refresh. Now how should I modify my code to refresh the fragments when it's "active"? MainActivityFragment.java: public class MainActivityFragment extends FragmentActivity implements ActionBar.TabListener{ private ViewPager viewPager; private TabsPagerAdapter mAdapter; private ActionBar actionBar; List<Fragment> fragments; private String[] tabs = { "KFZ", "Fahrten Log", "Kosten Track" }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main_fragment); // Initilization viewPager = (ViewPager) findViewById(R.id.pager); actionBar = getActionBar(); mAdapter = new TabsPagerAdapter(getSupportFragmentManager()); fragments = new Vector<Fragment>(); fragments.add(Fragment.instantiate(this, KFZFragment.class.getName(),savedInstanceState)); fragments.add(Fragment.instantiate(this, LogFragment.class.getName(),savedInstanceState)); viewPager.setAdapter(mAdapter); actionBar.setHomeButtonEnabled(false); actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); // Adding Tabs for (String tab_name : tabs) { actionBar.addTab(actionBar.newTab().setText(tab_name) .setTabListener(this)); } viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() { @Override public void onPageSelected(int position) { // on changing the page // make respected tab selected actionBar.setSelectedNavigationItem(position); } @Override public void onPageScrolled(int arg0, float arg1, int arg2) { } @Override public void onPageScrollStateChanged(int arg0) { } }); } @Override public void onTabReselected(Tab tab, FragmentTransaction ft) { // TODO Auto-generated method stub } @Override public void onTabSelected(Tab tab, FragmentTransaction ft) { viewPager.setCurrentItem(tab.getPosition()); } @Override public void onTabUnselected(Tab tab, FragmentTransaction ft) { // TODO Auto-generated method stub } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { if (keyCode == KeyEvent.KEYCODE_BACK) { } return super.onKeyDown(keyCode, event); } } Pls help me out.

• "Unable to get system library for project" after I upgraded to Android SDK 2.3 and ADT 8.0

  - by Jonas

  Today I upgraded to Android SDK 2.3 and I also upgraded the Eclipse Plugin Androi Developer Tools 8.0 (from 0.9.9). I also upgraded my Java Development Kit to 1.6_22. Now in Eclipse I get many errors in all my Android projects. The error messages are like: The type java.lang.Object cannot be resolved. It is indirectly referenced from required .class files. How can I fix this so I can use my Android projects again? In the Build Path for these projects, I don't have any references to an android.jar but a message: Unable to get system library for project

• What can't the NDK be used for?

  - by Android Eve

  From the official NDK site: The Android NDK... provides headers and libraries that allow you to build activities, handle user input, use hardware sensors, access application resources, and more, when programming in C or C++. If you write native code, your applications are still packaged into an .apk file and they still run inside of a virtual machine on the device. The fundamental Android application model does not change. Yet, it is always described as a companion tool to the Android SDK and as a toolset that allows to "implement parts of your applications using native-code languages such as C and C++". My understanding from this is that, unlike the Java based SDK, the NDK is not designed to implement certain parts of an Android application. Is this correct? If so, what parts doesn't the NDK allow implementing?

• Again: Android Stock browser vs. WebView?

  - by user2281606

  maybe a very easy question, but this drives me crazy... I work in company where we develope apps based on webviews. Everytime something went wrong, my boss tells me: "Hey look, the page runs nicely in the android browser, so it has to run that way in the app. Make it happen." I know that every manufacturer has his own implementation, discussed here: Android WebView VS Phone Browser But i want to keep my question simple: Is the android stock browser a pimped webview or in other words, extends the android browser from webview-class ? Thanks for any response?

• How to refresh a GridView?

  - by Daniel

  Hello everyone, I have a GridView which is pretty similar to the Google tutorial, except that I want to add the ImageViews on runtime (via a subactivity). The results are okay, but the layout of the View is messed up: The GridView doesn't fill the content of its parent, what do I have to do to design it properly? Here the code of adding the children: public void initializeWorkbench(GridView gv, Vector<String> items) { Prototype.workbench.setDimension(screenWidth, divider.height()+workbenchArea.height()); Prototype.workbench.activateWorkbench(); // this measures the workbench correctly Log.d(Prototype.TAG, "workbench width: "+Prototype.workbench.getMeasuredWidth()); // 320 Log.d(Prototype.TAG, "workbench height: "+Prototype.workbench.getMeasuredHeight()); // 30 ImageAdapter imgAdapter = new ImageAdapter(this.getContext(), items); gv.setAdapter(imgAdapter); gv.measure(screenWidth, screenHeight); gv.requestLayout(); gv.forceLayout(); Log.d(Prototype.TAG, "gv width: "+gv.getMeasuredWidth()); // 22 Log.d(Prototype.TAG, "gv height: "+gv.getMeasuredHeight()); // 119 Prototype.workbench.setDimension(screenWidth, divider.height()+workbenchArea.height()); } } activateWorkbench, setDimension and measure in the workbench (LinearLayout above the GridView): public void activateWorkbench() { if(this.equals(Prototype.workbench)) { this.setOrientation(VERTICAL); show = true; measure(); } } public void setDimension(int w, int h) { width = w; height = h; this.setLayoutParams(new LinearLayout.LayoutParams(width, height)); this.invalidate(); } private void measure() { if (this.getOrientation() == LinearLayout.VERTICAL) { int h = 0; int w = 0; this.measureChildren(0, 0); for (int i = 0; i < this.getChildCount(); i++) { View v = this.getChildAt(i); h += v.getMeasuredHeight(); w = (w < v.getMeasuredWidth()) ? v.getMeasuredWidth() : w; } if (this.equals(Prototype.tagarea)) height = (h < height) ? height : h; if (this.equals(Prototype.tagarea)) width = (w < width) ? width : w; } this.setMeasuredDimension(width, height); } The ImageAdapter constructor: public ImageAdapter(Context c, Vector<String> items) { mContext = c; boolean mExternalStorageAvailable = false; boolean mExternalStorageWriteable = false; String state = Environment.getExternalStorageState(); if (Environment.MEDIA_MOUNTED.equals(state)) { // We can read and write the media mExternalStorageAvailable = mExternalStorageWriteable = true; } else if (Environment.MEDIA_MOUNTED_READ_ONLY.equals(state)) { // We can only read the media mExternalStorageAvailable = true; mExternalStorageWriteable = false; } else { // Something else is wrong. It may be one of many other states, but // all we need // to know is we can neither read nor write mExternalStorageAvailable = mExternalStorageWriteable = false; } if (mExternalStorageAvailable && mExternalStorageWriteable) { for (String item : items) { File f = new File(item); if (f.exists()) { try { FileInputStream fis = new FileInputStream(f); Bitmap b = BitmapFactory.decodeStream(fis); bitmaps.add(b); files.add(f); } catch (FileNotFoundException e) { Log.e(Prototype.TAG, "", e); } } } } } And the xml layout: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:gravity="bottom" android:paddingLeft="0px" android:paddingTop="0px" android:paddingRight="0px"> <com.unimelb.pt3.ui.TransparentPanel android:id="@+id/workbench" android:layout_width="fill_parent" android:layout_height="10px" android:paddingTop="0px" android:paddingLeft="0px" android:paddingBottom="0px" android:paddingRight="0px"> <GridView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/gridview" android:layout_width="fill_parent" android:layout_height="fill_parent" android:columnWidth="90dp" android:numColumns="auto_fit" android:verticalSpacing="10dp" android:horizontalSpacing="10dp" android:stretchMode="columnWidth" android:gravity="center" /> </com.unimelb.pt3.ui.TransparentPanel> </LinearLayout>

The stack trace of from the thrown exception is java.lang.IllegalArgumentException: http://www.w3.org/2001/XMLSchema at javax.xml.validation.SchemaFactory.newInstance(SchemaFactory.java:181) at com.android.ide.eclipse.adt.internal.sdk.LayoutDevicesXsd.getValidator(Unknown Source) at com.android.ide.eclipse.adt.internal.sdk.LayoutDeviceManager.parseLayoutDevices(Unknown Source) at com.android.ide.eclipse.adt.internal.sdk.LayoutDeviceManager.loadDefaultLayoutDevices(Unknown Source) at com.android.ide.eclipse.adt.internal.sdk.LayoutDeviceManager.loadDefaultAndUserDevices(Unknown Source) at com.android.ide.eclipse.adt.internal.sdk.Sdk.<init>(Unknown Source) at com.android.ide.eclipse.adt.internal.sdk.Sdk.loadSdk(Unknown Source) at com.android.ide.eclipse.adt.AdtPlugin$13.run(Unknown Source) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55) I can't see that I've missed anything in the setup process, according to the instructions it should basically just work out of the box. Any ideas as to why this might fail?

• Android: ScrollView in flipper

  - by Manu

  I have a flipper: <?xml version="1.0" encoding="utf-8"?> <LinearLayout android:id="@+id/ParentLayout" xmlns:android="http://schemas.android.com/apk/res/android" style="@style/MainLayout" > <LinearLayout android:id="@+id/FlipperLayout" style="@style/FlipperLayout"> <ViewFlipper android:id="@+id/viewflipper" style="@style/ViewFlipper"> <!--adding views to ViewFlipper--> <include layout="@layout/home1" android:layout_gravity="center_horizontal" /> <include layout="@layout/home2" android:layout_gravity="center_horizontal" /> </ViewFlipper> </LinearLayout> </LinearLayout> The first layout,home1, consists of a scroll view. What should I do to distinguish between the flipping gesture and the scrolling? Presently: if I remove the scroll view, I can swipe across if I add the scroll view, I can only scroll. I saw a suggestion that I should override onInterceptTouchEvent(MotionEvent), but I do not know how to do this. My code, at this moment, looks like this: public class HomeActivity extends Activity { -- declares @Override public void onCreate(Bundle savedInstanceState) { -- declares & preliminary actions LinearLayout layout = (LinearLayout) findViewById(R.id.ParentLayout); layout.setOnTouchListener(new OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { if (gestureDetector.onTouchEvent(event)) { return true; } return false; }}); @Override public boolean onTouchEvent(MotionEvent event) { gestureDetector.onTouchEvent(event); return true; } class MyGestureDetector extends SimpleOnGestureListener { @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { // http://www.codeshogun.com/blog/2009/04/16/how-to-implement-swipe-action-in-android/ } } } Can anybody please guide me in the right direction? Thank you.

• phonegap.js crashes android app

  - by peirix

  I'm having this weird problem, where including the phonegap.js file in my project causes the app to crash on both the android emulator and my phone. I got the latest file from GitHub, so I can't see why this isn't working. This happens even if I try to build the sample project that's included in the PhoneGap download...

• Android: forward search queries to one single activity that handles search

  - by Stefan Klumpp

  I have an activity handling search (ACTIVITY_1), which works perfectly when I use the search (via SEARCH button on the phone) within/from this activity. However, when I use search from another activity (ACTIVITY_2..x) by implementing onNewIntent and forward the query string to my Search_Activity.class (ACTIVITY_1) @Override protected void onNewIntent(Intent intent) { Log.i(TAG, "onNewIntent()"); if (Intent.ACTION_SEARCH.equals(intent.getAction())) { Log.i(TAG, "===== Intent: ACTION_SEARCH ====="); Intent myIntent = new Intent(getBaseContext(), Search_Activity.class); myIntent.setAction(Intent.ACTION_SEARCH); myIntent.putExtra(SearchManager.QUERY, intent.getStringExtra(SearchManager.QUERY)); startActivity(myIntent); } } it always pauses ACTIVITY_2 first and then goes to onCreate() of ACTIVITY_2. Why does it recreate my ACTIVITY_2 when it is already there and doesn't go to onNewIntent directly? Is there another way I can forward search queries directly to ACTIVITY_1? For example via a setting in the Manifest.xml Is it possible to generally forward all search queries automatically to ACTIVITY_1 without even implementing onNewIntent in all the other activities? Currently I have to put an <intent-filter> in every single activity to "activate" my custom search there and forward the query then to the activity that handles search via the onNewIntent (as shown above). <activity android:name=".Another_Activity" android:theme="@style/MyTheme"> <intent-filter> <action android:name="android.intent.action.SEARCH" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> <meta-data android:name="android.app.searchable" android:resource="@xml/searchable" /> </activity>

• Standard Android Button with a different color

  - by Mike

  I'd like to change the color of a standard Android button slightly in order to better match a client's branding. For example, see the "Find a Table" button for the OpenTable application: The best way I've found to do this so far is to change the Button's drawable to the following drawable located in res/drawable/red_button.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="@drawable/red_button_pressed" /> <item android:state_focused="true" android:drawable="@drawable/red_button_focus" /> <item android:drawable="@drawable/red_button_rest" /> </selector> But doing that requires that I actually create three different drawables for each button I want to customize (one for the button at rest, one when focused, and one when pressed). That seems more complicated and non-DRY than I need. All I really want to do is apply some sort of color transform to the button. Is there an easier way to go about changing a button's color than I'm doing?

• Android WebView viewport

  - by alex2k8

  With html below I expected that the green rectangle would occupy only half of the screen, but on practice it occupies the whole screen width. I tried other values for viewport width, no luck. Any ideas why it does not work? Html <html> <head> <meta name="viewport" content="width=640" /> </head> <body> <div style="width: 300px; height: 50px; background: green;">300px</div> <div style="width: 600px; height: 50px; background: yellow;">600px</div> </body> </html> 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" > <WebView android:id="@+id/web_view" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout>

• Android : Handle OAuth callback using intent-filter

  - by Dave Allison

  I am building an Android application that requires OAuth. I have all the OAuth functionality working except for handling the callback from Yahoo. I have the following in my AndroidManifest.xml : <intent-filter> <action android:name="android.intent.action.VIEW"></action> <category android:name="android.intent.category.DEFAULT"></category> <category android:name="android.intent.category.BROWSABLE"></category> <data android:host="www.test.com" android:scheme="http"></data> </intent-filter> Where www.test.com will be substituted with a domain that I own. It seems : This filter is triggered when I click on a link on a page. It is not triggered on the redirect by Yahoo, the browser opens the website at www.test.com It is not triggered when I enter the domain name directly in the browser. So can anybody help me with When exactly this intent-filter will be triggered? Any changes to the intent-filter or permissions that will widen the filter to apply to redirect requests? Any other approaches I could use? Thanks for your help.
