    <p>I have a BroadcatReceiver registered in the manifest for the purpose of silencing audio when the phone rings. I would like the BroadcastListener to behave differently in 3 situations:</p> <ol> <li>If it was invoked while the user was using it.</li> <li>If it was invoked while in the background after the home button was pressed.</li> <li>If it was invoked while in the background after an exit request/ onBackButtonPressed().</li> </ol> <p>I want this ability to discern, because I think the broadcast receiver automatically and in a hidden way starts a service which sends a notification. If the user receives this notification after explicitly leaving the app it is annoying. </p> <p>Here are some of my attempts</p> <pre><code> public class MyBroadcastReceiver extends BroadcastReceiver { //private final static Global global = Global.getInstance(); private static final String TAG = MyBroadcastReceiver.class.getName(); @Override public void onReceive(Context context, Intent intent) { Log.d(TAG, "broadcast recieved"); //Log.d(TAG, "context package name is: " + context.getPackageName()); Bundle extras = intent.getExtras(); if (extras != null) { String state = extras.getString(TelephonyManager.EXTRA_STATE); Log.d(TAG, "State : " + state); if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) { Log.d(TAG, "context package name: " + context.getPackageName()); Global global = Global.getInstance(); global.shutUp(); Log.d(TAG, "global package name: " + global.getPackageName()); String phoneNumber = extras.getString(TelephonyManager.EXTRA_INCOMING_NUMBER); Log.d(TAG, "Calling number: " + phoneNumber); //TODO try to condition this if receiver activated from outside the application if(isAppOnForeground(context)) { Log.d(TAG, "app is in forgeround"); } else { Log.d(TAG, "app is not in forgeround"); } if(isMyServiceRunning(context)) { Log.d(TAG, "service running"); } else { Log.d(TAG, "service isn't running"); } //global.stopService(new Intent(ReturnService.class.getName())); //Log.d(TAG, "requested return service stoped"); } } //I think this return is imperative so that return service isn't invoked return; } private boolean isAppOnForeground(Context context) { ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE); List&lt;RunningAppProcessInfo&gt; appProcesses = activityManager.getRunningAppProcesses(); if (appProcesses == null) { return false; } final String packageName = context.getPackageName(); for (RunningAppProcessInfo appProcess : appProcesses) { if (appProcess.importance == RunningAppProcessInfo.IMPORTANCE_FOREGROUND &amp;&amp; appProcess.processName.equals(packageName)) { return true; } } return false; } private boolean isMyServiceRunning(Context context) { ActivityManager manager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE); for (RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) { if (ReturnService.class.getName().equals(service.service.getClassName())) { return true; } } return false; } </code></pre> <p>}</p>

    1. COyou say "app was dormant or in the background". What do you mean your app is, an activity, a service, or a combination of activities and services?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
