Question

I have a broadcast receiver (c2dm push receiver).
When i receive a push, i want this to happen:

• Start a notification, where you are led to StopAlarmActivity (Done!)
• If the application are in front, start StopAlarmActivity (How can i check this)

My main problem is that i can’t get the broadcast receiver to start the StopAlarmActivity for me.

I have registered the broadcast receiver in the manifest.

Here’s the code i use to try to start an activity:

Intent intentHome = new Intent(context, StopAlarmActivity.class);
          intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
          context.startActivity(intentHome);

This is the stacktrace message:

11-20 00:29:30.514: E/AndroidRuntime(13612):
java.lang.RuntimeException: Unable to start receiver
com.packagename.PushReceiver: android.util.AndroidRuntimeException:
Calling startActivity() from outside of an Activity context requires
the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?

I’ve seen some people saying it’s just to add FLAG_ACTIVITY_NEW_TASK to the intent, and the exception is also telling me that, so i really don’t understand why it’s not working.

Anyone got an idea?
Thanks in advance!

In your code you have:

intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

but your intent for this new activity is intentHome. Change that line to:

intentHome.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
