Add a method to get All Defined Permissions of the AndroidManifest.xml file.

Is there already an issue requesting this feature?

• I have searched the existing issues.

Please select affected platform(s)

• Android
• iOS
• Windows

Use case

Currently Permission.values returns all permissions, if we had a getDefinedPermissions() that would return only the permissions i put on androidManifest.xml i coud loop the returned list to see if there is a permission that is not granted, and if there is i could just call list.request();

Proposal

i once made something like this on native android

  if (PermissionCheck.needToAsk(this)) {
            PermissionCheck.ask(this);
            return;
        }

public class PermissionCheck {

    private PermissionCheck() {

    }

    public static boolean needToAsk(Context context) {
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) {
            return false;
        }
        try {
            PackageInfo packageInfo;
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
                packageInfo = context.getPackageManager().getPackageInfo(context.getPackageName(), PackageManager.PackageInfoFlags.of(PackageManager.GET_PERMISSIONS));
            } else {
                packageInfo = context.getPackageManager().getPackageInfo(context.getPackageName(), PackageManager.GET_PERMISSIONS);
            }
            String[] permissions = packageInfo.requestedPermissions;

            for (String permission : permissions) {
                if (isNotGranted(context, permission)) {
                    return true;
                }
            }

        } catch (PackageManager.NameNotFoundException e) {
            e.printStackTrace();
        }
        return false;
    }

    private static boolean isNotGranted(Context context, String permission) {
        if (Build.VERSION.SDK_INT < 31 && (permission.contains("BLUETOOTH_SCAN") || permission.contains("BLUETOOTH_ADVERTISE") || permission.contains("BLUETOOTH_CONNECT"))) {
            return false;
        }
        return ContextCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED;
    }


    public static void ask(Activity context) {
        try {
            PackageInfo packageInfo;
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
                packageInfo = context.getPackageManager().getPackageInfo(context.getPackageName(), PackageManager.PackageInfoFlags.of(PackageManager.GET_PERMISSIONS));
            } else {
                packageInfo = context.getPackageManager().getPackageInfo(context.getPackageName(), PackageManager.GET_PERMISSIONS);
            }
            String[] permissions = packageInfo.requestedPermissions;
            List<String> list = new ArrayList<>();
            for (String permission : permissions) {
                if (isNotGranted(context, permission)) {
                    list.add(permission);
                }
            }
            if (list.isEmpty()) {
                return;
            }
            String[] array = list.toArray(new String[0]);
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                ActivityCompat.requestPermissions(context, array, 0);
            }


        } catch (PackageManager.NameNotFoundException e) {
            MetodosEstaticos.toastException(e, context);
        }
    }
}

But i guess a getDefinedPermissions would be enough.
