How does Google Play Store App request permission before downloading the app? After the user responds to the system permissions dialog, the system then invokes your app's implementation of onRequestPermissionsResult.

The system passes in the user response to the permission dialog, as well as the request code that you defined, as shown in the following code snippet:.

If the user denies a permission request, your app should help users understand the implications of denying the permission. In particular, your app should make users aware of the features that don't work because of the missing permission. When you do so, keep the following best practices in mind:.

Guide the user's attention. Highlight a specific part of your app's UI where there's limited functionality because your app doesn't have the necessary permission. Several examples of what you could do include the following:. Be specific.

Don't display a generic message; instead, mention which features are unavailable because your app doesn't have the necessary permission. Don't block the user interface. In other words, don't display a full-screen warning message that prevents users from continuing to use your app at all. At the same time, your app should respect the user's decision to deny a permission. Starting in Android 11 API level 30 , if the user taps Deny for a specific permission more than once during your app's lifetime of installation on a device, the user doesn't see the system permissions dialog if your app requests that permission again.

The user's action implies "don't ask again. In certain situations, the permission might be denied automatically, without the user taking any action. Similarly, a permission might be granted automatically as well. It's important to not assume anything about automatic behavior. Each time your app needs to access functionality that requires a permission, you should check that your app is still granted that permission.

To provide the best user experience when asking for app permissions, also see App permissions best practices. Starting in Android 11 API level 30 , whenever your app requests a permission related to location, microphone, or camera, the user-facing permissions dialog contains an option called Only this time , as shown in Figure 2.

If the user selects this option in the dialog, your app is granted a temporary one-time permission. Your app can then access the related data for a period of time that depends on your app's behavior and the user's actions:. When the user next opens your app and a feature in your app requests access to location, microphone, or camera, the user is prompted for the permission again. If your app targets Android 11 API level 30 or higher and isn't used for a few months, the system protects user data by automatically resetting the sensitive runtime permissions that the user had granted your app.

Learn more in the guide about app hibernation. Some apps depend on access to sensitive user information related to call logs and SMS messages. If you want to request the permissions specific to call logs and SMS messages and publish your app to the Play Store, you must prompt the user to set your app as the default handler for a core system function before requesting these runtime permissions.

For more information on default handlers, including guidance on showing a default handler prompt to users, see the guide on permissions used only in default handlers. To grant all runtime permissions automatically when you install an app on an emulator or test device, use the -g option for the adb shell install command, as demonstrated in the following code snippet:.
