Allows an app to create windows using the type TYPE_APPLICATION_OVERLAY, shown on top of all other apps. Very few apps should use this permission; these windows are intended for system-level interaction with the user. Note: If the app targets API level 23 or higher, the app user must explicitly grant this permission to the app through a permission management screen. The app requests the user's approval by sending an intent with action ACTION_MANAGE_OVERLAY_PERMISSION. The app can check whether it has this authorization by calling android.provider.Settings#canDrawOverlays Settings.canDrawOverlays()
Allows an application to write to external storage. Note: If both your ' minSdkVersion and ' targetSdkVersion values are set to 3 or lower, the system implicitly grants your app this permission. If you don't need this permission, be sure your '>getExternalFilesDir and getExternalCacheDir. If this permission is not allowlisted for an app that targets an API level before Q this permission cannot be granted to apps.

Allows an application to install a shortcut in Launcher. In Android O (API level 26) and higher, the INSTALL_SHORTCUT broadcast no longer has any effect on your app because it's a private, implicit broadcast. Instead, you should create an app shortcut by using the android.content.pm.ShortcutManager#requestPinShortcut requestPinShortcut()method from the android.content.pm.ShortcutManagerclass.
