I'm trying to get app list using services. I'm using queryIntentActivities to get app list. I believe the problem is giving the wrong permissions from manifest but i couldn't figure it out. Does anyone have an idea on this ?
Thanks for any help!
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
PackageManager packageManager = getPackageManager();
List<ResolveInfo> allApps = packageManager.queryIntentServices(intent, 0);
for (ResolveInfo resolveInfo : allApps) {
Log.d("Labels", (String) resolveInfo.loadLabel(packageManager));
}
return super.onStartCommand(intent, flags, startId);
}
and there is how i call this service from activity
Intent intent = new Intent(getApplicationContext(),MyService.class);
intent.setAction(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
startService(intent);
here is the manifest file.
<service android:name=".MyService"
android:permission="android.permission.QUERY_ALL_PACKAGES">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</service>
