Allows an application to read from external storage. Any app that declares the WRITE_EXTERNAL_STORAGE permission is implicitly granted this permission. This permission is enforced starting in API level 19. Before API level 19, this permission is not enforced and all apps still have access to read from external storage. You can test your app with the permission enforced by enabling

Allows an application to receive the ACTION_BOOT_COMPLETED that is broadcast after the system finishes booting. If you don't request this permission, you will not receive the broadcast at that time. Though holding this permission does not have any security implications, it can have a negative impact on the user experience by increasing the amount of time it takes the system to start and allowing applications to have themselves running without the user being aware of them. As such, you must explicitly declare your use of this facility to make that visible to the user.
Allows an application to request installing packages. Apps targeting APIs greater than 25 must hold this permission in order to use ACTION_INSTALL_PACKAGE.
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.
