startActivity not working in push handler

Question

I am trying to start a new activity when a particular type of push notification is tapped. I've extended ParsePushBroadcastReceiver class (I'm using Parse) and overridden onPushOpen method.

When I tap on the push, the following code does get called:

Intent postIntent = new Intent(App.context, SinglePostActivity.class);
postIntent.putExtra(SinglePostActivity.ARG_POST_ID, postId);
context.startActivity(postIntent);

But nothing happens. I have my activity registered successfully in AndroidManifest. How can I start the activity successfully?

@MD As I've explained the question, it's the application context. — Can Poyrazoğlu, Apr 17 '15 at 11:11
@CanPoyrazoğlu: Simply question is: **why not using `context` which is first parameter of `onReceive` or `onPushOpen` method for starting Activity?** — ρяσѕρєя K, Apr 17 '15 at 11:15
@ρяσѕρєяK didn't see that one. Anyway, switched to that, nothing changed. still not working. — Can Poyrazoğlu, Apr 17 '15 at 11:17
@CanPoyrazoğlu: Also change `Intent postIntent = new Intent(App.context, SinglePostActivity.class);` to `Intent postIntent = new Intent(context, SinglePostActivity.class);` — ρяσѕρєя K, Apr 17 '15 at 11:18
@ρяσѕρєяK wait, in the debugger, I've got this: Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want? — Can Poyrazoğlu, Apr 17 '15 at 11:20
@CanPoyrazoğlu: Great just add following line `postIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);` before `context.startActivity(postIntent);` — ρяσѕρєя K, Apr 17 '15 at 11:21
@ρяσѕρєяK I will, but I want to know its implications. Would it change any crucial behavior? — Can Poyrazoğlu, Apr 17 '15 at 11:22
@CanPoyrazoğlu: No change in behavior this is way to start Activity from ParsePushBroadcastReceiver — ρяσѕρєя K, Apr 17 '15 at 11:25
@ρяσѕρєяK okay, thanks. it worked. could you post this as an answer so I can accept it? — Can Poyrazoğlu, Apr 17 '15 at 11:25

Probably App.context causing issue.

Use Context parameter of onPushOpen method for creating Intent and accessing startActivity Activity method :

Intent postIntent = new Intent(context, SinglePostActivity.class);
....
postIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(postIntent);
