求助关于车机桌面的逆向

scy444888

前言：我的小奇瑞搞到车机的工程密码后，可以用adb安装软件了，但是安装的软件的在桌面上不能显示，只能通过其他方式打开，很不方便
尝试过别的桌面app，使用起来效果一般还让本来就不富裕的内存雪上加霜，于是想着把桌面app逆向一下看能不能解决这个问题
pass: 自己对安卓app是一窍不通，只懂点js，只能找资料现学现试，而且不知道这个app做了什么限制在模拟器上和手机均无法运行，每次都只能到车上去试，很麻烦

先说一下目前的进度，apk反编译之后通过观察，发现桌面的图标在res/layout目录下都有对应的xml文件

不是很懂这些id是怎么定义的，在经过一段时间的摸索找到了这个方法，猜测应该就是在这里实现的点击打开图标的操作

试着加了两个图标之后重新编译打包安装到车机上无法打开，选择桌面的地方识别不到车机桌面了，再不知道该怎么查了，大佬们给帮忙看看
加个未修改apk的链接：https://www.lanzv.com/iYD7b1mvkyrg

建议替换第三方车机桌面，可以实现正常使用。

系统自带的车机桌面，应该是有些限制的版本。

希望你早点解决，俺是21款7p，也是ADB安装

太惨了，把车机搞坏了

我说一个思路，我在电视盒子上用过的。

先看一下原桌面上有什么用不到的APP，把它弄下来看下包名，就是 com.xxx.xxxx 这样子的。
然后自己编一个APP使用这个包名，并安装到车机上去。
这样在桌面上就可以直接启动这个APP，在自己的APP中实现其它APP的跳转。
这个方法不用动原桌面，风险较低。

好主意，原来的APP是手动替换掉还是直接adb安装替换掉？

安装方法不重要，能装上去就是好办法。
重名的APP直接装应提示签名不符，需要先卸载，再安装。
