NOTE:
Google has officially deprecated C2DM as of June 26,2012. This means that
C2DM has stopped accepting new users and quota requests. Existing C2DM
developers are encouraged to migrate to Google's new push service, called
GoogleCloud messaging for Android (GCM).

How to finish all Activity's running in background in Android

---------------------------------------------------------------------------
Hello All,

This is very easy solution for this question.

A->B->C->D

We start from A and now we are on D activity.

We used intent for jump one activity to another.

Note: yet we not use finish...

Means A,B,C is running in background...

So, therefore we need to finish all (A,B,C) activities from activity C.
--------------------------
Step 1 : Save A, B, C activity in static Activity Vector. Create Static class and create Activity Vector.

public class VARIABLES_STACK_RANJIT {
                 public static Vector<Activity> v_context = new Vector<Activity>();
}

Step 2 : Write following code in A,B,C activity
               i) VARIABLES_STACK_RANJIT.v_context.add(A.this);
               ii) VARIABLES_STACK_RANJIT.v_context.add(B.this);
               i) VARIABLES_STACK_RANJIT.v_context.add(C.this);

Step 3 : Write final code in D activity

Start loop and finish manually all saved activity.

                 for (int i = 0; i < VARIABLES_STACK.v_context.size(); i++) {
(VARIABLES_STACK.v_context.elementAt(i)).finish();
Log.e("Activity :" + i, "finished...");
}

Don't reload activity when orientation changes in an Android
