Also, Shizuku is significantly faster than shell. title details Supports adb usage If your "root required app" only needs adb permission, you can easily expand the audience by using Shizuku. title details Save your time Shizuku has detailed documentation to guide users. Only you need to do is to let the users install Shizuku.	Copyright © 2019 RikkaApps

As Easy as you are a system app

private static final IPackageManager PACKAGE_MANAGER = IPackageManager.Stub.asInterface(
    new ShizukuBinderWrapper(SystemServiceHelper.getSystemService("package")));

public static void grantRuntimePermission(String packageName, String permissionName, int userId) {
    try {
        PACKAGE_MANAGER.grantRuntimePermission(packageName, permissionName, userId);
    } catch (RemoteException tr) {
        throw new RuntimeException(tr.getMessage(), tr);
    }
}

::: tip

There a few more steps to do, like checking permission or if Shizuku is running. :::
