is it because i am calling it from a handler ?
this handler is a private member variable of my activity
private Handler myhandler = new Handler() {
/* (non-Javadoc)
* @see android.os.Handler#handleMessage(android.os.Message)
*/
@Override
public void handleMessage(Message msg) {
switch (msg.what) {
case FINISHED:
ShowAlert();
break;
}
super.handleMessage(msg);
}
};
