android.view.WindowManager$BadTokenException: Unable to add window android.view.ViewRootImpl$W@71dc214 -- permission denied for window type 2026
Solution:
TYPE_DISPLAY_OVERLAY需要
android.Manifest.permission.INTERNAL_SYSTEM_WINDOW
AndroidManifest.xml
<permission android:name="android.permission.INTERNAL_SYSTEM_WINDOW" android:protectionLevel="signature" />
app要 sign platform key才可使用
