您可以在清单上简单地授予此许可权，而忽略此许可权错误:

<uses-permission android:name="android.permission.PACKAGE_USAGE_STATS" tools:ignore="ProtectedPermissions"/>

<uses-permission android:name="android.permission.PACKAGE_USAGE_STATS" tools:ignore="ProtectedPermissions"/>

比使用以下代码获得许可

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if (!isAccessGranted()) {
        Intent intent = new Intent(Settings.ACTION_USAGE_ACCESS_SETTINGS);
        startActivity(intent);
    }
}


private boolean isAccessGranted() {
        try {
            PackageManager packageManager = getPackageManager();
            ApplicationInfo applicationInfo = packageManager.getApplicationInfo(getPackageName(), 0);
            AppOpsManager appOpsManager = (AppOpsManager) getSystemService(Context.APP_OPS_SERVICE);
            int mode = 0;
            if (android.os.Build.VERSION.SDK_INT > android.os.Build.VERSION_CODES.KITKAT) {
                mode = appOpsManager.checkOpNoThrow(AppOpsManager.OPSTR_GET_USAGE_STATS,
                        applicationInfo.uid, applicationInfo.packageName);
            }
            return (mode == AppOpsManager.MODE_ALLOWED);

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