Android. How to Get context from different activity

Question

I'm playing with the GCM.

Everything is perfect using the example on https://code.google.com/p/gcm/source/checkout Im getting notifications on my app with the gcm messages,

Now I want to add the message in a listView located on my MainActivity.

Im receiving my messages on a different class (GcmIntentService.java). How can I get MainActivity context to sendBroadcast.

Already tried with

private static Context mContext;

public static Context getContext() {
    return mContext;
}

public static void setContext(Context context) {
    mContext = context;
}

But is not working.

Any Ideas.

Thanks

Answer 1

I am not sure what you are doing. But keeping the below in mind

Do not keep long-lived references to a context-activity (a reference to an activity should have the same life cycle as the activity itself). http://www.curious-creature.org/2008/12/18/avoid-memory-leaks-on-android/

You can do as below

Example:

 new MyClass(ActivityName.this);

class MyClass
{
      Context mContext; 
      public MyClass(Context context)
      {
          mContext=context;
      } 
}

Answer 2

pass the context variable through constructor .
