  • Android HTTP get methods

    - by Nick
    I have written a number of applications for blackberry and am just starting in Android. It seems to me that android has a lot more built in functions. I am starting by recreating some of my BB apps on Android and on one I take a few xml sites and parse them out. On blackberry I implemented this by creating a class that extended a thread. I would construct a new instance of this class with the parameters of my http request and it would call a function back in my main class, sending it the results. I am tempted to reuse my code, but am curious if android has something better built in. I have been looking at the handler class as well as possible using a service. Bascially, I would like to start a new thread that will return a document of a specific url. Thanks!

  • Port Android App to Desktop?

    - by CodeJustin.com
    I'm just wondering if it would be possible (and legal) to port an Android app to desktop? I'm creating an android game that would work well on PC too (even with the cellphone like layout) and was thinking that maybe I could 'embed' an android emulator with an installer or would that process be a bit hard for a novice Java coder?

  • getView only shows Flagged Backgrounds for drawn Views, It does not show Flagged Background when scroll to view more items on list

    - by Leoa
    I am trying to create a listview that receives a flagged list of items to indicate a status to the user. I have been able to create the flag display by using a yellow background (see image at bottom). In Theory, the flagged list can have many flagged items in it. However in my app, only the first three flagged backgrounds are shown. I believe this is because they are initially drawn to the screen. The Flagged background that are not drawn initially to the screen do not show. I'd like to know how to get the remaining flags to show in the list. ListView Recycling: The backgrounds in the listView are being recycled in getView(). This recycling goes from position 0 to position 9. I have flags that need to match at positions 13, 14 and so on. Those positions are not being displayed. listView.getCheckedItemPositions() for multiple selections: This method will not work in my case because the user will not selected the flags. The flags are coming from the server. setNotifyOnChange() and/or public virtual void SetNotifyOnChange (bool notifyOnChange): I'm not adding new data to the list, so I don't see how this method would work for my program. Does this method communicate to getview when it is recycling data? I was unable to find an answer to this in my research. public void registerDataSetObserver: This may be overkill for my problem, but is it possible to have an observer object that keeps track of the all the positions in my items list and in my flag list no matter if the view is recycled and match them on the screen? Code: package com.convention.notification.app; import java.util.Iterator; import java.util.ArrayList; import java.util.List; import android.app.Activity; import android.content.Context; import android.graphics.Color; import android.os.Bundle; import android.text.Html; import android.util.Log; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.view.ViewParent; import android.widget.AdapterView; import android.widget.ArrayAdapter; import android.widget.TextView; public class NewsRowAdapter extends ArrayAdapter<Item> { private Activity activity; private List<Item> items; private Item objBean; private int row; private List<Integer> disable; View view ; int disableView; public NewsRowAdapter(Activity act, int resource, List<Item> arrayList, List<Integer> disableList) { super(act, resource, arrayList); this.activity = act; this.row = resource; this.items = arrayList; this.disable=disableList; System.out.println("results of delete list a:"+disable.toString()); } public int getCount() { return items.size(); } public Item getItem(int position) { return items.get(position); } public long getItemId(int position) { return position; } @Override public int getItemViewType(int position) { for(int k =0;k < disable.size();k++){ if(position==disable.get(k)){ //System.out.println( "is "+position+" value of disable "+disable.get(k)); disableView=disable.get(k); //AdapterView.getItemAtPosition(position); } } return position; } @Override public View getView(final int position, View convertView, ViewGroup parent) { View view = convertView; ViewHolder holder; if (view == null) { LayoutInflater inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE); view = inflater.inflate(row, null); getItemViewType(position); long id=getItemId(position); if(position==disableView){ view.setBackgroundColor(Color.YELLOW); System.out.println(" background set to yellow at position "+position +" disableView is at "+disableView); }else{ view.setBackgroundColor(Color.WHITE); System.out.println(" background set to white at position "+position +" disableView is at "+disableView); } //ViewHolder is a custom class that gets TextViews by name: tvName, tvCity, tvBDate, tvGender, tvAge; holder = new ViewHolder(); /* setTag Sets the tag associated with this view.

  • error executing aapt, all of the sudden

    - by pjv
    I know there are a lot of these topics around but none seem to help in my case, nor describe it exactly. The best similar one is aapt not found under the right path. My problem is that I can be using Eclipse for a whole evening programming, compiling and using my device, and then suddenly I get "error executing aapt" for my current project and ofcourse R.java isn't (properly) generated anymore. I then restart Eclipse and everything goes away. I'm seeing this once a day on average however. I've recently switched to amd64 and installed the latest Android-2.3 SDK and matching tools. I know that there is now a platform-tools folder that has an aapt version that should work SDK version independently. At first I had added this directory to my PATH, as instructed on the SDK website. I've also tried not adding it to my path and making a link platforms/android-9/tools so that every SDK version might use it's own old copy. Needless to say, platform-tools/aapt is there and has the right permissions, and I have been able to execute it on the command-line at any time. When I do write a faulty xml file or sorts, and appropriately get an error, I see an extra line that says "aapt: /lib32/libz.so.1: no version information available". I'm running a recent Gentoo linux system. I have everything installed to support x86 on amd64, but have re-emerged emul-linux-x86-baselibs and zlib just to be sure. The problem persists. I do see some pages that spell horror over some zlib bugs, but I'm not sure if that's related. I realize I'm not on the reference Ubuntu platform, but surely the difference cannot be that great? It might very well be a bug in aapt or the tools itself. Why would it suddenly stop working? I also experience that the ids in R.java were incorrect, namely that simple findViewById() code would give ClassCastExceptions because of mixed ids the one time, and then work perfectly without any changes bu only a "clean project", in the aftermath of a failing aapt. Finally, I've run a few commands on aapt, that don't seem to add any extra information: #ldd aapt ./aapt: /lib32/libz.so.1: no version information available (required by ./aapt) linux-gate.so.1 => (0xffffe000) librt.so.1 => /lib32/librt.so.1 (0x4f864000) libpthread.so.0 => /lib32/libpthread.so.0 (0x4f849000) libz.so.1 => /lib32/libz.so.1 (0xf7707000) libstdc++.so.6 => /usr/lib/gcc/x86_64-pc-linux-gnu/4.4.4/32/libstdc++.so.6 (0x415e9000) libm.so.6 => /lib32/libm.so.6 (0x4f876000) libgcc_s.so.1 => /lib32/libgcc_s.so.1 (0x4fac6000) libc.so.6 => /lib32/libc.so.6 (0x4f5ed000) /lib/ld-linux.so.2 (0x4f5ca000) #file aapt aapt: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.15, not stripped Can anybody tell anything wrong with my configuration? Does it smell like a bug perhaps (otherwise let's report it (again))? Update 2010-01-06: I've gained some more knowledge. When I recently was trying to export a signed apk, I ran into another error message (full details from the Eclipse error view) regarding aapt I hadn't seen before. Note here too, that I can just restart Eclipse and can export apks again without problems, at least for a little while. I'm starting to think it is related to lack of memory on my system. The message "onvoldoende geheugen beschikbaar" means "insufficient memory available". I have also been seeing insufficient memory errors in DDMS when I'm dumping HPROF files. Here is the error log (shortened): !ENTRY com.android.ide.eclipse.adt 4 0 2011-01-05 23:11:16.097 !MESSAGE Export Wizard Error !STACK 1 org.eclipse.core.runtime.CoreException: Failed to export application at com.android.ide.eclipse.adt.internal.project.ExportHelper.exportReleaseApk(Unknown Source) at com.android.ide.eclipse.adt.internal.wizards.export.ExportWizard.doExport(Unknown Source) at com.android.ide.eclipse.adt.internal.wizards.export.ExportWizard.access$0(Unknown Source) at com.android.ide.eclipse.adt.internal.wizards.export.ExportWizard$1.run(Unknown Source) at org.eclipse.jface.operation.ModalContext$ModalContextThread.run(ModalContext.java:121) Caused by: com.android.ide.eclipse.adt.internal.build.AaptExecException: Error executing aapt.

  • Calling Status Bar notification from method from other class.

    - by Jez Fischer
    Firstly, I am new to both android and Java. I have two classes, my main.class and Note.class. I am calling the notification method from my Note.class in my main.class when i press a button. The issue is with this line from the Note.class : PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0); notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent); When the method is called it force closes. I believe the problem to be with the "this" in PendingIntent.getActivity(this, 0, notificationIntent, 0);, but I am unsure what to change it to. The notification code works fine if it's in the main class. I would be very grateful for any guidance. Edit: Main class : http://pastebin.com/05Yx0a48 Note.class : package com.adamblanchard.remindme.com.adamblanchard; import com.adamblanchard.remindme.R; import android.app.Activity; import android.app.Notification; import android.app.NotificationManager; import android.app.PendingIntent; import android.content.Context; import android.content.Intent; import android.os.Bundle; public class Note extends Activity { public CharSequence note = "not changed"; int HELLO_ID = 1; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); setTitle("Remind Me!"); } //Notification Method public void callNotification() { // TODO Auto-generated method stub String ns = Context.NOTIFICATION_SERVICE; final NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns); int icon = R.drawable.launcher; CharSequence tickerText = "Remind Me!"; long when = System.currentTimeMillis(); final Notification notification = new Notification(icon, tickerText, when); notification.flags |= Notification.FLAG_AUTO_CANCEL; final Context context = getApplicationContext(); CharSequence contentTitle = "Remind Me!"; CharSequence contentText = note; Intent notificationIntent = new Intent(context, AndroidNotifications.class); PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0); notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent); mNotificationManager.notify(HELLO_ID, notification); HELLO_ID++; } } Debug Output : Thread [<1 main] (Suspended (exception IllegalStateException)) Note(Activity).getSystemService(String) line: 3536 Note.callNotification() line: 37 remindme$1$1.onClick(DialogInterface, int) line: 72 AlertDialog(AlertController$ButtonHandler).handleMessage(Message) line: 159 AlertController$ButtonHandler(Handler).dispatchMessage(Message) line: 99 Looper.loop() line: 123 ActivityThread.main(String[]) line: 3647 Method.invokeNative(Object, Object[], Class, Class[], Class, int, boolean) line: not available [native method] Method.invoke(Object, Object...) line: 507 ZygoteInit$MethodAndArgsCaller.run() line: 839 ZygoteInit.main(String[]) line: 597 NativeStart.main(String[]) line: not available [native method] This is the debug output I get, plus a force close popup on the device.

  • Another ArrayIndexOutOfBoundsException in ListView

  • Can't get a LiveFolder to launch my activity like it should

    - by Felix
    I was able to create a ContentProvider for a LiveFolder, but I can't seem to be able to create my intents correctly, so it always gives "Application is not installed on your phone" errors when clicking on items inside the folder. My Activity is defined like so, in the manifest: <activity android:name=".MyActivity"> <intent-filter> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> </activity> Then, I create the intents I place in the LiveFolders.INTENT column like this: i = new Intent(); i.setAction(null); i.setClassName("my.package.here", ".MyActivity"); I don't get why this is not working. Maybe I'm making some stupid mistake, but please point me in the right direction.

  • Why my buttons OnClick event fails to fire?

    - by Pentium10
    I have an activity, where the ListView holds customized linear layout elements for each row. One of the rows has a button defined as: <Button android:text="Pick a contact" android:id="@+id/btnPickContact" android:layout_width="wrap_content" android:gravity="center_vertical" android:layout_height="wrap_content"></Button> Then in java, I have this code: ((Button) row.findViewById(R.id.btnPickContact)).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI); intent.putExtra(EXTRA_ONLINE_ID, (String)v.getTag(TAG_ONLINE_ID)); act.startActivityForResult(intent, PICK_CONTACT); } }); In this setup the event fails to start. Also I've tried by implementing the interface: @Override public void onClick(View v) { Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI); intent.putExtra(EXTRA_ONLINE_ID, (String)v.getTag(TAG_ONLINE_ID)); startActivityForResult(intent, PICK_CONTACT); } still no luck, the event doesn't fire. What to do?

    - by Labeeb P
    Hi, I have made two folders, res/layout and res/layout-land The output i got If I start the application in portrait mode, it will always use the xml in layout folder if the application run in portrait mode. And will not use xml in layout-land if i change the device to landscape mode If it start in landscape mode it only use the xml in layout-land The xml is not switching when the orientation change What i expect was It should use the xml in layout folder while it is in portrait mode and use the xml in layout-land while in landscape mode In the Manifest file i have added android:configChanges="orientation" for the activity and <supports-screens android:resizeable="true" android:largeScreens="true" android:normalScreens="true" android:anyDensity="true" /> Did i missed any thing here?
