I won't show a received push notification from appearing top notifications menu my notification if it has for example key update. For now if I get notification with this key, all notifications are in the notification bar. I want to not present this notifications for user.
I'm using WakefulBroadcastReceiver for handle notifications like below:
public class PusherReceiver extends WakefulBroadcastReceiver {
private boolean isAppOnForeground(Context context) {
ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.RunningAppProcessInfo> appProcesses = activityManager.getRunningAppProcesses();
if (appProcesses == null)
return false;
final String packageName = context.getPackageName();
for (ActivityManager.RunningAppProcessInfo appProcess : appProcesses) {
if (appProcess.importance == ActivityManager.RunningAppProcessInfo.IMPORTANCE_FOREGROUND && appProcess.processName.equals(packageName)) {
return true;
}
}
return false;
}
public void onReceive(final Context context, Intent intent) {
Log.i("SimpleWakefulReceiver", "Starting service @ " + SystemClock.elapsedRealtime());
if (!isAppOnForeground((context))) {
String pushNotificationBody = intent.getStringExtra("alert");
try {
JSONObject notificationData = new JSONObject(pushNotificationBody);
// This is the Intent to deliver to our service.
Intent service = new Intent(context, BackgroundService.class);
// Put here your data from the json as extra in in the intent
service.putExtra("notification", pushNotificationBody);
Log.i("PUSH_NOTIFICATION_JSON", "RECEIVED JSON " + notificationData);
// Start the service, keeping the device awake while it is launching.
if (!notificationData.has("update")) {
startWakefulService(context, service);
} else {
// Do nothing
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}
}
UPDATE:
I changed project a little and with Onesignal and his NotificationExtenderService, I did something like below:
public class NotificationNotDisplayingExtender extends NotificationExtenderService {
@Override
protected boolean onNotificationProcessing(OSNotificationReceivedResult receivedResult) {
String notification = receivedResult.toString();
String notificationBody = receivedResult.payload.body;
JSONObject notificationBodyJSON = null;
try {
notificationBodyJSON = new JSONObject(notificationBody);
} catch (JSONException e) {
e.printStackTrace();
}
JSONObject pushNotificationData = notificationBodyJSON;
boolean hidden = false;
if (pushNotificationData.has("update")) {
Log.i("NOTIFICATION MANAGER", "PREVENT DISPLAY NOTIFICATION");
hidden = true;
}
// Return true to stop the notification from displaying.
return hidden;
}
}
And it prevent displaying notifications with update key, but now I don't receive it in my PusherReceiver to start my service. Is there easy way to send data from my NotificationNotDisplayingExtender receivedResult to my PusherReceiver?
For now it looks like my PusherReceiver don't fire his onReceive method.
Many thanks for help in advance.
Every time you notify the NotificationManager to show a notification, you provide an ID to be used for the notification to edit or cancel that notification later on. If you show a notification by manager.notify(notificationId, notification), you can cancel it with manager.cancel(notificationId).
If you want to remove all the notifications, you can use NotificationManager.cancelAll().
