Android Framework实战预制packages/apps下应用APK预制使用Android.bp方式

Posted 2022-05-27 Android高级知识分享官

hi粉丝朋友大家好！
以前在android framework入门课讲解过第三方应用apk的预制相关内容，那时候是基于Android 8.1的Android.mk,但大家依旧对Android.bp的预制不知道怎么做，所以很多粉丝经常私下问我，干脆这里给大家blog分享，这里我们来使用Android.bp进行预制，因为现在高版本大部分其实都是使用Android.bp，新版本packages/apps下面android 12几乎看不到Android.mk的身影，所以当然我们也需要与时俱进。但是Android.bp相对来说资料较少，不像以前的Android.mk可以继承很多linux的makefile,所以我这边些Android.bp大部分也只能依葫芦画瓢，参考其他应用怎么写的。

下面开始正题：

下面我们其实只需要把原来的Android.mk替换成Android.bp具体Android.bp内容如下：

    // Make sure the build system doesn't try to resign the APK
    dex_preopt: 
        enabled: false,
    ,

    arch: 
        arm: 
            apk: "MyApp1.apk",
        ,
        arm64: 
             apk: "MyApp1.apk",
        ,
        x86: 
               apk: "MyApp1.apk",
        ,
        x86_64: 
                apk: "MyApp1.apk",
        ,
    ,
   certificate: "platform",

最后可以编译一下：make MyApp1
