Method Detail

recycleUnchecked

@HiddenApi
 @Implementation(minSdk=21)
public void recycleUnchecked()

Hook to unscheduled the callback when the message is recycled. Invokes unschedule() and then calls through to the package private method Message.recycleUnchecked() on the real object.

recycle

@Implementation(maxSdk=20)
protected void recycle()

Hook to unscheduled the callback when the message is recycled. Invokes unschedule() and then calls through to Message.recycle() on the real object.

setScheduledRunnable

public void setScheduledRunnable(Runnable r)

Stores the Runnable instance that has been scheduled to invoke this message. This is called when the message is enqueued by ShadowMessageQueue.enqueueMessage(android.os.Message, long) and is used when the message is recycled to ensure that the correct Runnable instance is removed from the associated scheduler.

Parameters:

r - the Runnable instance that is scheduled to trigger this message.

if ($api >= 21) * @see #recycleUnchecked()

else * @see #recycle()

end

isInUse

@Implementation
protected boolean isInUse()

Convenience method to provide access to the private Message.isInUse() method. Note that the definition of “in use” changed with API 21:

In API 19, a message was only considered “in use” during its dispatch. In API 21, the message is considered “in use” from the time it is enqueued until the time that it is freshly obtained via a call to Message.obtain(). This means that in API 21 messages that are in the recycled pool will still be marked as “in use”.

Returns:

true if the message is currently “in use”, false otherwise.

getNext

public Message getNext()

Convenience method to provide getter access to the private field Message.next.

Returns:

The next message in the current message chain.

setNext

public void setNext(Message next)

Parameters:

next - the new next message for the current message.
