My problem is whenever I clear memory on "Task Manager/RAM" tab of my android device my notification disappears. What can I do to make my ongoing notification stay even if I clear memory?
This is the class by which i send the notification :-
public class GcmIntentService extends IntentService {
public static final int NOTIFICATION_ID = 1;
private NotificationManager mNotificationManager;
private final static String TAG = "GcmIntentService";
private Context mContext;
public GcmIntentService() {
super("GcmIntentService");
}
@Override
protected void onHandleIntent(Intent intent) {
Bundle extras = intent.getExtras();
Log.d(TAG, "Notification Data Json :" + extras.getString("message"));
GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
String messageType = gcm.getMessageType(intent);
if (!extras.isEmpty()) {
if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR
.equals(messageType)) {
sendNotification("Send error: " + extras.toString());
} else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED
.equals(messageType)) {
sendNotification("Deleted messages on server: " + extras.toString());
} else if (GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE
.equals(messageType)) {
// This loop represents the service doing some work.
for (int i = 0; i < 5; i++) {
Log.d(TAG, " Working... " + (i + 1) + "/5 @ "
+ SystemClock.elapsedRealtime());
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
Log.i(TAG, "Completed work @ " + SystemClock.elapsedRealtime());
sendNotification(extras.getString("message"));
}
} // Release the wake lock provided by the WakefulBroadcastReceiver.
GcmBroadcastReceiver.completeWakefulIntent(intent);
} // Put the message into a notification and post it.
private void sendNotification(String msg) {
mNotificationManager = (NotificationManager) this
.getSystemService(Context.NOTIFICATION_SERVICE);
Intent intent = new Intent(this, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP);
intent.putExtra("KEY","aman");
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder mBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(this)
.setSmallIcon(android.R.drawable.sym_def_app_icon)
.setContentTitle("Telepoh")
.setStyle(new NotificationCompat.BigTextStyle().bigText(msg))
.setContentText(msg)
.setDefaults(Notification.DEFAULT_SOUND | Notification.DEFAULT_VIBRATE);
mBuilder.setContentIntent(contentIntent);
mBuilder.getNotification().flags |= Notification.FLAG_AUTO_CANCEL;
mBuilder.setAutoCancel(true);
mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
}
private int getNotificationIcon() {
boolean useWhiteIcon = (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP);
return useWhiteIcon ? R.drawable.gcm : R.drawable.push_icon;
}
}
This is my GcmBroadcastReceiver class :-
public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent)
{ ComponentName comp = new ComponentName(context.getPackageName(),
GcmIntentService.class.getName());
startWakefulService(context, (intent.setComponent(comp)));
setResultCode(Activity.RESULT_OK);
}
}
This is my Manifest File :-
