Show Push Notifications When Application Open/closed In Different Way

In my app I've a several Activities that inherit from one BaseActivity. My application receive push notification with GCMBaseIntentService I need to implement the next logic: When

Solution 1:

It seems that PackageManager.queryBroadcastReceivers() returns all receivers declared in application manifests matching a given Intent.

Note however that this will not include receivers registered with Context.registerReceiver(); there is currently no way to get information about those.

You can use the following code in onReceive() to determine if the application/activity is running or not

ActivityManager am = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
List<RunningTaskInfo> taskInfo = am.getRunningTasks(1);
Log.d("current task :", "CURRENT Activity ::" + taskInfo.get(0).topActivity.getClass().getSimpleName());
ComponentName componentInfo = taskInfo.get(0).topActivity;
if(componentInfo.getPackageName().equalsIgnoreCase("your.package.name")){
    //Activity in foreground, broadcast intent
} 
else{
    //Activity Not Running//Generate Notification
}

Solution 2:

You can check whether application is in background or foreground using this code :

public String isApplicationSentToBackground(final Context context) {
    ActivityManageram= (ActivityManager) context
            .getSystemService(Context.ACTIVITY_SERVICE);
    List<RunningTaskInfo> tasks = am.getRunningTasks(1);
    if (!tasks.isEmpty()) {
        ComponentNametopActivity= tasks.get(0).topActivity;
        if (!topActivity.getPackageName().equals(context.getPackageName())) {
            return"false";
        }
    }

    return"true";
}

If it returns "true" then show notification else show dialog box.

When I debug the context.getPackageManager().queryBroadcastReceivers(pushReceivedIntent, 0).size() always equals to 0.

For this don't pass 0 in notify().Instead pass "Calendar.getInstance().getTimeInMillis()" value.This will show all the notifications based on time.

Hope this will help you.
