Android最近在其SDK源代码中引入了@SystemApi.看起来像之前的@hide注释一样有效,因为它们也被从SDK jar类中剥离.
应用程序是否有可能以与旧的@hide API不同的方式调用它们.
/**
* Indicates an API is exposed for use by bundled system applications.
* <p>
* These APIs are not guaranteed to remain consistent release-to-release,
* and are not for use by apps linking against the Android SDK.
* </p><p>
* This annotation should only appear on API that is already marked <pre>@hide</pre>.
* </p>
*
* @hide
