Reference to Current Activity in android

Can some one help me get the reference to the current activity from the Myapp that extends Application. I'm trying to implement a simple shake feature that uses the sesmic library. Once the shake is detected I need to have the reference to the current activity so that I can save a screen shot of the current view. I need to access the current activity something like 

enter public class MyApp extends Application {

public onSomeTriggerCallThisFunction() {
    Activity currentActivity = getCurrentActivity();
}}

Can someone help me with getCurrentActivity()

you should set currentActivity when you call each activity in onCreate or onResume activity method like that. G is my Application class and currentActivity is my static field in G class

@Override
protected void onResume() {
    super.onResume();
    G.currentActivity = this;
}

For API level 14 :

They added new public function

public void registerActivityLifecycleCallbacks (Application.ActivityLifecycleCallbacks callback)

Implementing them in your application class can give access to current activity.
