If the application is closed (not running), then you need to run one activation while clicking on the notification. And if the application is running, then another. How to do it?

    And then GCM? This refers to the flags PendingIntent.getActivity () , which are specified in the notification. Depending on this, it is possible to launch or, on the contrary, not to launch a new Activity when clicking on a notification.

      1) Override the Application class

       public class MyApplication extends Application { public static final boolean IS_ACT_RUNNING = false; }

      2) Indicate this class in the manifest in a special tag.

       <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" ... > ... <application android:name=".MyApplication" android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/ThemeDark" > ... <receiver android:name=".NotifClickBroadcastReceiver " android:exported="false" > <intent-filter> <action android:name="myAction" /> </intent-filter> </receiver> </application> </manifest>

      3) In this class, create an IS_ACT_RUNNING variable of type boolean

      4) Assign the variable true to the desired activation in the onResume () methods; in onPause () - false;

       @Override protected void onResume() { super.onResume(); MyApplication.IS_ACT_RUNNING=true; } @Override public void onPause() { super.onPause(); MyApplication.IS_ACT_RUNNING=false; }

      5) When clicking on a notification, check this variable. So you will know if the desired activity is running.

       public class NotifClickBroadcastReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { String isActRunning = String.valueOf( MyApplication.IS_ACT_RUNNING); Log.e("LOG", "isActRunning: "+isActRunning ); } }

      When creating a notification, specify the call of the above mentioned receiver by clicking on the notification:

        NotificationCompat.Builder builder = new NotificationCompat.Builder(context); Intent i = new Intent(this, NotifClickBroadcastReceiver.class); i.setAction("myAction"); PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, PendingIntent.FLAG_UPDATE_CURRENT); builder.setContentIntent(pi);

      Start somewhere a flag that determines whether the application is running or not.
