getCurrentActivity

@Nullable
protected final android.app.Activity getCurrentActivity()

Get the activity to which this context is currently attached, or null if not attached. DO NOT HOLD LONG-LIVED REFERENCES TO THE OBJECT RETURNED BY THIS METHOD, AS THIS WILL CAUSE MEMORY LEAKS. For example, never store the value returned by this method in a member variable. Instead, call this method whenever you actually need the Activity and make sure to check for null.
