问题描述

我想要求才允许卸载/删除我的应用程序的用户键入密码。我怎样才能实现这个功能？

I would like to require that a user type a password before being allowed to uninstall/remove my application. How can I implement this functionality?

推荐答案

您可以通过做到这一点：

You could do this by:

• 在第一次安装在您的应用程序，安装一个单独的应用程序/包（守望者）。
• 唯一的阶级守望者中包含的一个BroadcastReceiver监听 ACTION_PACKAGE_REMOVED
• 添加一个BroadcastReceiver到您的应用程序，还监听 ACTION_PACKAGE_REMOVED
• 当一个意图被广播到你的接收机之一，检查是否仍安装其他组件。如果不是（用户只需卸载它），提示输入密码 - 如果它是错的，重新安装其他组件。如果这是正确的，卸载自己。

• The first time your app is installed, install a separate application/package ("watcher").
• The only classes "watcher" contains is a BroadcastReceiver that listens for ACTION_PACKAGE_REMOVED
• Add a BroadcastReceiver to your application that also listens for ACTION_PACKAGE_REMOVED
• When a intent is broadcast to one of your receivers, check if the other component is still installed. If is isn't (the user just uninstalled it), prompt for the password - if it's wrong, reinstall the other component. If it's right, uninstall yourself.
