转发COMPAT在一定程度上保证主要版本。在Android上你的目标的最小API SPEC。只要你不叫私有的API，谷歌保持兼容性向前发展上加入自己的开放移动联盟设备。

Forward compat is somewhat assured on major versions. On Android you target a minimum api spec. As long as your are not calling private APIs, Google keeps compatibility going forward on devices that join in on their Open Mobile Alliance.

这并不意味着别人不能获得Android源，并且打破了所有的兼容性释放自己的基于Android的操作系统。这些设备不会得到谷歌的市场的地方，因为，谷歌测试中只得到授权的设备，以便使用。如果这是你在哪里释放，你可能不会有任何麻烦。

It doesn't mean someone can't get the Android source and release an Android based OS of their own that breaks all compatibility. These devices wouldn't get Google's Market Place because only licensed devices that Google tests get to use that. If that is where you are releasing, you probably won't have any trouble.
