Start your activity B by Activity A

Intent intent = new Intent(ActivityA.this,ActivityB.Class);
startActivityForResult(intent,0);

finish your activity B with 

Intent intent = new Intent();
setResult(RESULT_OK,intent );       
finish();

now in ActivityA

@Override
  protected void onActivityResult(int requestCode, int resultCode, Intent data)
  {
    super.onActivityResult(requestCode, resultCode, data);
    //Do your work here in ActivityA

  }

Instead of this int pid = android.os.Process.myPid(); android.os.Process.killProcess(pid); just use finish();. THis will help you to come back to the previous activity. As per your code, the application was completely killed.
