锁定安兔兔安装版本的逻辑就是在系统安装apk的时候，进行一个包名过滤，符合我要的包名的话，就会执行安装我给定路径的apk，逻辑就是这样，也可以锁定其他apk版本，具体实现如下： 首先是先拷贝进去一个apk
diff --git a/device/mediatek/system/common/apk/antutu-benchmark-v9.apk b/device/mediatek/system/common/apk/antutu-benchmark-v9.apk
new file mode 100755
index 00000000000..9ccfd3fe76c
Binary files /dev/null and b/device/mediatek/system/common/apk/antutu-benchmark-v9.apk differ

后面就是实现上面说的那个逻辑了：

这个方法我也是参考CSDN上写的一篇关于安卓十一锁定apk版本的博客，说白了我这也是cv了一下（cv工程师），链接：http://t.csdnimg.cn/q5abO，有兴趣的可以看一下，下面是如何让设备在5度的时候有一个温度过高的弹窗，60度关机，-5度弹窗，-10度关机，这个是在驱动层改的（傻逼公司让我们做应用的也搞一点驱动的东西，还不加钱），因为我做这个关机的项目是安卓十一（上面的是安卓十三），所以我用的是kernel-4.14，安卓十三用的是kernel-4.19或者是kernel-5.10，方法如下：

我公司做的是MTK平台的机器，这个温度弹窗、关机什么的MTK是已经写好了（低温的没有，高温的有），只需要改一下就可以了，不过低温的那个宏（#define BAT_LOW_TEMP_PROTECT_ENABLE）是一定要加的，不然低温是不会关机的，高温的就是改那个mt6739.dts就可以了，最近这一个多月都在搞一个项目的GMS，客户需求做的很少，也没时间写笔记，后面有时间写一篇解决GMS一些fail项方法的文章，这个解谷歌GMS的fail项的文章网上写的很少，可能现在我们国家对出口安卓产品的数量不多或者那些大佬对于这些方法都是偷着藏着的，哈哈哈
