[android-developers] Re: What is the proper result for Handler.Callback.handleMessage() ?

[Walt Armour]

Finally found the time to dig into the source.

Based on this snippet in core/java/android/os/Handler.java :

    /**
     * Handle system messages here.
     */
    public void dispatchMessage(Message msg) {
        if (msg.callback != null) {
            handleCallback(msg);
        } else {
            if (mCallback != null) {
                if (mCallback.handleMessage(msg)) {
                    return;
                }
            }
            handleMessage(msg);
        }
    }

handleMessage() should return true if the message was handled.  This
will prevent any additional handling of the message.
