问题背景：虚拟机（7.0）和三星平板（4.4）可以正常安装，真机（9.0）不能安装
问题机型：华为 mate 10 pro
系统版本：9.0
开发环境：win7
查到了很多解决方案：
挨个试：

1. clean、rebuild、重启
   之前碰见这样的就是这么处理的，然而这次没什么卵用
2. 包名首字母大写了
   参考链接：https://stackoverflow.com/questions/37066617/failure-install-parse-failed-manifest-malformed
   检查完发现没有，排除（检查清单文件就可以）
3. 包名不正确
   检查后发现：清单文件的包名和gradle中的不一致
   之前修改过包名，但是低版本手机上没有报错
   以后切记修改包名一定要检查所有地方
4. 清单文件配置错误
   
   某次导入一个第三方库的时候，在application节点下增加了两条属性：

	android:appComponentFactory="1231321"
    tools:replace="android:appComponentFactory"

如果设置：android:appComponentFactory=""，低版本不会报错，高版本报错，必须设置一个值，任意字符都可以，就是不能为空。

问题总结：

实际是两个问题导致的这个问题，一是包名不一致，二是application下新增的属性没有适配9.0

• 第一个问题是因为改包名没有细致检查（别手欠改包名，要改就单拉出一个分支，改完认真检查）

• 第二个问题是因为不了解这两个属性干啥用，当时按照studio的提示加上了，事后没有查相关的资料，这回长记性了

    	查了一下发现：没有介绍是干什么用的，都说为了解决某个问题要加上，以后查到再补充
  

下面是一些问题截图，可以忽略
