Question

嘿，我想当用户尝试卸载应用时，会有密码解锁。我遵循以下代码：

android: require password when uninstall app

但清单中出现错误“android：description =”@ string / descript“” 请帮助我。严重陷入其中。谷歌也没有答案

    try the following code in your service 
    public static final String UNINSTALLER ="com.android.packageinstaller.UninstallerActivity";
private ActivityManager activityManager = null;
private ExecutorService executorService;


@Override
public void onCreate() {
    super.onCreate();

    executorService = Executors.newSingleThreadExecutor();

    activityManager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
    LockerThread thread = new LockerThread();
    executorService.submit(thread);
}

   private void protactApp(String packname) {
            Intent pwdIntent = null;
            pwdIntent = new Intent("uninstaller.receiver");
            sendBroadcast(pwdIntent);


        }
class LockerThread implements Runnable {

    private String lastname;

    public LockerThread() {

    }

    @Override
    public void run() {

            ComponentName act = activityManager.getRunningTasks(1).get(0).topActivity;
            String packname = act.getPackageName();



            if (act.getClassName().equals(UNINSTALLER)) {
                Log.d("Tag", "package to be uninstalled");
                protactApp(UNINSTALLER);
            }
        }

从接收器中你可以在卸载应用程序时获取操作，这样你准备好的密码或模式的屏幕就可以在卸载之前启动，如applock应用程序

它不会对4.3或更高版本有所帮助，但我发布了一个链接，您可以在其中找到解决方案以及为什么不能这样做的原因。这是link。希望它能帮助您理解这一背景下的真正里程碑。
