更改组件状态时带有权限拒绝的SecurityException

Question

Intent launchIntent = pm.getLaunchIntentForPackage(package_name);

String className = launchIntent.getComponent().getClassName();

ComponentName componentName = new ComponentName(package_name, className);
pm.setComponentEnabledSetting(componentName,PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);

这是我的代码，我在最后一行得到以下错误
