android9系统android studio项目改成用android.mk编译引用v7包第

android9系统android studio项目改成用android.mk编译引用v7包第三方jar包，aar文件和so库文件

原文件在：\vendor\..\package\DVR

打包apk在：\out\target\product\msm8953_64\system\app\DVR

?

项目放进系统中编译前提是APP 本身已能正常在对应系统中使用了，只是现在需要用mmm编译到系统包中

?

先用android studioMake project成功后，Clean Project项目，清除不用的内容

然后把项目整个复制到\vendor\..\package\下

进入项目根目录，新建一个android.mk文件

android.mk语法请自行百度

以下是本项目，需要引用v7支持，第三方jar包，aar文件和so库文件
