I run my application in two different Android devices. The first is an Arnova 9 G2 Tablet and the second a Sony Xperia P. In the Arnova tablet my application executed successfully, but in the Sony Xperia P phone, the LogCat displays me the following error:
/data/data/com.example.androidjnetpcaptest/interfaces: open failed:

interfacesTextView = ( TextView ) rootView.findViewById( R.id.interfacesTextView );
interfacesTextView.setText( lines );
interfacesTextView.setMovementMethod( new ScrollingMovementMethod() );
return rootView;
}
}
The trouble is the use of the absolute path /data/data/com.example. androidjnetpcaptest/interfaces. You should not assume this is the data location for the app. Apps can be moved to external storage and since ICS the system supports multiple users (people) where the app gets different storage per user. Instead, use Context.getFilesDir() to get the app-private location where files can be created and stored.
You do not need any special permissions to read/write this space.

I am trying use AsyncTask to extract an image over the internet and display on the RecyclerViewer but I am getting the following error message, which's captured from my Exception in my doInBackground from my RecyclerViewAdapter class:
08-02 00:11:25.608: E/ImageDownload(5753): Download failed: Permission denied (missing INTERNET permission?)
See full version of AsyncTask sub-class below:
class GetImageFromNet extends AsyncTask<String, Void, Bitmap> {
private RVAdapter.PersonViewHolder personViewHolder;
private String url = "http://ia.media-imdb.com/images/M/MV5BNDMyODU3ODk3Ml5BMl5BanBnXkFtZTgwNDc1ODkwNjE#._V1_SX300.jpg";
public GetImageFromNet(RVAdapter.PersonViewHolder personViewHolder){
this.personViewHolder = personViewHolder;
}
protected Bitmap doInBackground(String... params) {
try {
InputStream in = new java.net.URL(url).openStream();
Bitmap bitmap = BitmapFactory.decodeStream(in);
return bitmap;
//NOTE: it is not thread-safe to set the ImageView from inside this method. It must be done in onPostExecute()
} catch (Exception e) {
Log.e("ImageDownload", "Download failed: " + e.getMessage());
}
return null;
}
protected void onPostExecute(Bitmap bitmap) {
if (isCancelled()) {
bitmap = null;
}
personViewHolder.personPhoto.setImageBitmap(bitmap);
}
I have no idea why I am getting above error since I have already added the following permission access in my AndroidManifest.xml:

Please help!
Move your <uses-permission> elements to be immediate children of <manifest>, above your <application> element.
Update your manifest as:-

Got myself newly registered on AirPush. I integrated bundle SDK with my App. When I tested it for the first time, I got a couple of impressions. It also shows 2 impressions on dashboard.
Now I am unable to fetch the impressions. Did contact the developer team but to no avail.
My code of MainActivity goes like this :
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// MMSDK.initialize(this);
// setup a new adView and initialize an adRequest to it.
setupAirPushAdView();
}
#Override
public void onResume() {
super.onResume();
if ((getResources().getConfiguration().screenLayout
& Configuration.SCREENLAYOUT_SIZE_MASK)
== Configuration.SCREENLAYOUT_SIZE_SMALL) {
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
try {
if (!appStarted) {
setContentView(R.layout.main);
appStarted = true;
}
} catch (Exception e) {
Toast.makeText(this, e.getMessage() + "\n" + e.getClass().toString() + "\n" + e.getLocalizedMessage() + "\n", Toast.LENGTH_LONG).show();
}
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run() {
perform();
}
}, 2000);
}
private void perform() {
setContentView(R.layout.app_home);
if (!appStarted) {
// attachAdView();
attachAirPushAdView();
appStarted = true;
}
...
Other Methods :
private void setupAirPushAdView() {
ma = new MA(this, null, false);
airPushAdView = new AdView(this, AdView.BANNER_TYPE_IN_APP_AD, AdView.PLACEMENT_TYPE_INTERSTITIAL, false, false,
AdView.ANIMATION_TYPE_LEFT_TO_RIGHT);
}
private void attachAirPushAdView() {

When user want to uninstall app from android device, I want user uninstall button click event for that application.
I am getting event of application is removed from device, but I want to show pop-up before application is removed. I am trying to achieve same like doing in 'App Lock' application.
Here is my code to get application removed event through broadcast receiver. But I am totally blank about uninstall button click or before pop-up click. Please guide me in right direction.
Thanks in advance.
public class MainActivity extends Activity {
CustomBroadcastReceiver mApplicationsReceiver;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mApplicationsReceiver=new CustomBroadcastReceiver();
IntentFilter filter = new IntentFilter(Intent.ACTION_PACKAGE_ADDED);
filter.addAction(Intent.ACTION_PACKAGE_REMOVED);
filter.addAction(Intent.ACTION_PACKAGE_CHANGED);
filter.addAction(Intent.ACTION_PACKAGE_ADDED);
filter.addAction(Intent.ACTION_PACKAGE_REPLACED);
filter.addAction(Intent.ACTION_PACKAGE_RESTARTED);
filter.addAction(Intent.ACTION_PACKAGE_VERIFIED);
filter.addAction(Intent.ACTION_PACKAGE_INSTALL);
filter.addAction(Intent.ACTION_PACKAGE_FIRST_LAUNCH);
filter.addAction(Intent.ACTION_DELETE);
filter.addAction(Intent.ACTION_DEFAULT);
filter.addDataScheme("package");
registerReceiver(mApplicationsReceiver, filter);
}
}
public class CustomBroadcastReceiver extends BroadcastReceiver {
/**
* This method captures the event when a package has been removed
*/
#Override
public void onReceive(Context context, Intent intent)
{
System.out.println("Hello from CustomBroadcastReceiver");
if (intent != null) {
String action = intent.getAction();
System.out.println("L1123 : "+action);
if (action.equals(intent.ACTION_PACKAGE_REMOVED)) {
//Log the event capture in the log file ...
System.out.println("The package has been removed");
}
}
}

Please try to get the top activity in the task via ActivityManager, and check if it is the uninstall activity.
Core code:
ComponentName topActivity = mActivityManager.getRunningTasks(1).get(0).topActivity;
String packageName = topActivity.getPackageName();
String className = topActivity.getClassName();
Log.v(TAG, "packageName" + packageName);
Log.v(TAG, "className" + className);
if ("com.android.packageinstaller".equals(packageName)
&& "com.android.packageinstaller.UninstallerActivity".equals(className)) {
//Do anything you want here
}
The following permissions which you are using are granted to system apps only. Make sure you have rooted device to allow such permissions.
<uses-permission android:name="android.permission.BROADCAST_PACKAGE_REMOVED" />
<uses-permission android:name="android.permission.INSTALL_PACKAGES" />
<uses-permission android:name="android.permission.DELETE_PACKAGES" />
I am trying to send an Intent from the onCreate in an Activity to start an IntentService. However the IntentService's onHandleIntent is never being received. I have tried changing around the Manifest with Intent-filters but nothing seems to be working. No exceptions are being thrown, but the IntentService is simply not called.
Here is the onCreate
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
db = new TwitterDB(this);
String[] columns = new String[1];
columns[0] = TwitterDB.TEXT;
tAdapter = new SimpleCursorAdapter(this, 0, null, columns, null, 0);
tweets = (ListView)findViewById(R.id.listtwitter);
tweets.setAdapter(tAdapter);
Intent intent = new Intent(this, SyncService.class);
intent.putExtra("action", SyncService.TWITTER_SYNC);
this.startService(intent);
}
Here is the creator and onHandleIntent of the IntentService class, I know it is not being called because logcat never shows "Retrieved intent". The constructor is not called either (There was a log call in there, but I removed it.
public SyncService(){
super("SyncService");
twitterURI = Uri.parse(TWITTER_URI);
Log.i("SyncService", "Constructed");
}
#Override
public void onHandleIntent(Intent i){
int action = i.getIntExtra("action", -1);
Log.i("SyncService", "Retrieved intent");
switch (action){
case TWITTER_SYNC:
try{
url = new URL(twitterString);
conn = (HttpURLConnection)url.openConnection();
syncTwitterDB();
conn.disconnect();
}catch(MalformedURLException e){
Log.w("SyncService", "Twitter URL is no longer valid.");
e.printStackTrace();
}catch(IOException e){
Log.w("SyncService", "Twitter connection could not be established.");
e.printStackTrace();
}
break;
default:;
// invalid request
}
}
And here is the Manifest.xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.twitter"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="15" />
<uses-permission android:name="android.permission.INTERNET"/>
<application android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".TwitterTwoActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<service android:name="SyncService"/>
</activity>
</application>
</manifest>
Move your service declaration outside of the scope of the TwitterTwoActivity in the XML file, as I have done here:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.twitter"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="15" />
<uses-permission android:name="android.permission.INTERNET"/>
<application android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".TwitterTwoActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service android:name="SyncService"/>
</application>
</manifest>
You need to define the path to the service in your manifest, simply putting the name is not sufficient.
Change
<service android:name="SyncService"/>
to
<service android:name=".SyncService"/>
if SyncService is in the root of your package, add respective folder before .SyncService if needed.
I'm trying to create a launcher/homescreen. The application crashes on restart.
Debugger displays : "Unable to get provider mono.MonoRuntimeProvider". You have to wait a long time before the MonoRuntimeProvider is started, and then the app works. Any ideas to resolve this problem?
Activity1.cs
[Activity(Label = "Test application", MainLauncher = true, Icon = "#drawable/icon")]
public class Activity1 : Activity

{
base.OnCreate(bundle);
RequestWindowFeature(WindowFeatures.NoTitle);
Window.SetFlags(WindowManagerFlags.Fullscreen, WindowManagerFlags.Fullscreen);
// Set our view from the "main" layout resource
SetContentView(Resource.Layout.Main);
}
catch (Exception ex)
{
Log.Error("TestError","Test Error:" + ex.Message);
}
//
}

Find the solution:
MonoRuntimeProvider is required for debugging. Once I made a release, it worked perfectly...
