Android的锁屏和键盘控制 [英] Android Lock Screen and Keyboard Controls

问题描述

我是一部分的方式，通过编写一个媒体播放器的应用程序为Android。这一切都进行得很顺利，到目前为止，但是我现在达到了困难的阶段！

I am part way through writing a media player app for Android. It's all going really well so far, however I am now reaching the difficult stage!

我有两个问题。我需要实现一个服务活动？据我了解，这是必需的，以允许应用程序继续在后台运行。然而，当我移动到平板电脑上的其他程序，并返回到应用程序没有问题，我的工作正常。是否有人可以解释什么优点是服务？

I have two questions. Do i need to implement a service activity? As I understand it, this is required to allow the app to continue working in the background. However, mine is working fine while I move to other programs on the tablet, and returns to the app without problems. Can someone please explain what the advantages are of services?

其次，我想媒体播放器与ICS标准的锁屏控件整合，也使其利用具有键盘播放/暂停控制跳过片（如华硕变压器）的。我想AP preciate，如果有人可以点我在正确的方向让我开始。从我在Google上搜寻它似乎BroadcastReciever是必要的，或者RemoteControlClient，但我不知道从哪里开始！

Secondly, I would like to integrate the media player with the standard lock screen controls in ICS, and also make it take advantage of tablets (such as the asus transformer) that have keyboard play/pause skip controls. I would appreciate it if someone could point me in the right direction to get me started. From my googling it would seem that BroadcastReciever is needed, or perhaps RemoteControlClient, but I've no idea where to start!

我有动作条选项卡，其中包含音乐播放片段，很快一个主要活动视频播放器片段。

I have a main activity with actionbar tabs, which contain a music player fragment and soon a video player fragment.

我是否需要专门创建一个布局锁屏，或者我可以使用标准的API的？

Do i need to create a layout specifically for the lock screen, or can i make use of standard API's?

任何帮助感激地接受！
