Answer 1

你可以在这里找到一些权限:

https://github.com/android/platform_frameworks_base/blob/master/core/res/AndroidManifest.xml

另一个解决方案是以下代码示例:

getPackageManager().getPermissionInfo(name,  0).protectionLevel

在你的情况下这是这个信息:

<!-- Allows an application to watch and control how activities are
         started globally in the system.  Only for is in debugging
         (usually the monkey command).
         <p>Not for use by third-party applications. -->
    <permission android:name="android.permission.SET_ACTIVITY_WATCHER"
        android:label="@string/permlab_runSetActivityWatcher"
        android:description="@string/permdesc_runSetActivityWatcher"
        android:protectionLevel="signature" />
