Android 15.0 启动app时设置密码锁

news 2025/8/5 7:30:24

在安卓15.0的系统产品开发中，对于限制某些app的启动的功能中，在项目中的需求是在点击app启动的时候，根据包名设置密码锁，当输入正确的密码的时候来启动这个app，否则
就不能启动这个app,达到限制使用app的目的，这就需要在app启动的时候，检测app的包名，然后在app启动的时候弹出输入密码的窗口，让用户输入只密码，当输入正确的密码
才可以使用app，这就需要先熟悉app的启动流程，然后来实现这个功能后

思路：

  1. 使用contentPrivide 储存已加锁的app包名字符串，使用 SystemProperties储存加锁状态和设置的密码
  2. 在launcher3中 点击桌面图标进行状态判断
  3. 在最近任务视图中，设置加锁后，立即清空最近任务视图

补丁如下：
