android studio导入classes.jar

mmm frameworks/base

拷贝out/target/common/obj/JAVA_LIBRARIES/framework_intermediates/classes.jar到任一目录，在下图中指定到该目录的classes.jar

1、创建classes

2、app添加依赖classes

android studio导入classes.jar

3、添加完MODULE classes.jar之后编译错误
       Caused by: com.android.tools.r8.utils.AbortException: Error: null,
       Cannot fit requested classes in a single dex file (# methods: 101390 > 65536 ; # fields: 74816 > 65536)

       修改app / build.gradle文件以启用multidex并将multidex库添加为依赖项，如下所示：
       android {
           defaultConfig {
               ...
               minSdkVersion 15
               targetSdkVersion 28
               multiDexEnabled true
           }
           ...
       }

       dependencies {
       implementation 'com.android.support:multidex:1.0.3'
       }
