高通 Android 10/Android 12 应用里面拦截Home键功能

1、由于最近测试部反馈需求产测工具里面需要拦截Home功能

2、可能大家一想到拦截脑海里面可能会想到dispatch/或者onkeydown或者onTouchEvent事件等等，可能网上也有一些文章比如像这种Android拦截HOME键_android 屏蔽home键_天残神功的博客-CSDN博客

3、Android10 在PhoneWindowManager里面interceptKeyBeforeDispatchingInner方法去拦截Home键 return 0就 ok 代码如下

4、Android 12 也是在PhoneWindowManager里面interceptKeyBeforeDispatching 去拦截Home键 代码如下

5、到这里基本结束了，然后编译aosp源码 烧录 然后在产测工具里面是不会退到主页，在其他应用功能正常 这里只是抛砖引玉如果要拦截修改其他按键方法类似，大家都可以举一反三，转载请注明出处，谢谢！有需要学习可以加我微信kdanmobile高通 Android 10/Android 12 应用里面拦截Home键功能_KdanMin的博客-CSDN博客
