1.异常现象
在实现 播放在线 TS 文件 的功能的时候，按照之前的思路是，集成 ExoPlayer 来实现播放功能。一开始是以源码的方式依赖到主工程，但考虑到项目的可维护性，决定编译 ExoPlayer 相关组件，得到对应的 aar 依赖包，拷贝到主工程中，避免对 ExoPlayer 的依赖。移植完毕后，启动播放器，发现报错了，异常如下：
-6694/com.mycompany.myproject D/AndroidRuntime: Shutting down VM05-10 18:47:55.986 6694-6694/com.mycompany.myproject E/AndroidRuntime: FATAL EXCEPTION: main Process: com.mycompany.myproject, PID: 6694 java.lang.NoClassDefFoundError: Failed resolution of: Lorg/jacoco/agent/rt/internal_773e439/Offline; at com.mycompany.ui.components.ListArrayAdapter.$jacocoInit(ListArrayAdapter.java) at com.mycompany.ui.components.ListArrayAdapter.<init>(ListArrayAdapter.java) at com.mycompany.myproject.NationalityFragment.onCreateView(NationalityFragment.java:47) at android.support.v4.app.Fragment.performCreateView(Fragment.java:1974) at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:1067) at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:1252) at android.support.v4.app.BackStackRecord.run(BackStackRecord.java:742) at android.support.v4.app.FragmentManagerImpl.execPendingActions(FragmentManager.java:1617) at android.support.v4.app.FragmentController.execPendingActions(FragmentController.java:339) at android.support.v4.app.FragmentActivity.onStart(FragmentActivity.java:602) at android.app.Instrumentation.callActivityOnStart(Instrumentation.java:1220) at android.app.Activity.performStart(Activity.java:5953) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2261) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2360) at android.app.ActivityThread.access$800(ActivityThread.java:144) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1278) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:135) at android.app.ActivityThread.main(ActivityThread.java:5221) at java.lang.reflect.Method.invoke(Native Method) at java.lang.reflect.Method.invoke(Method.java:372) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:899) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:694)复制代码
2.分析
关键信息：
java.lang.NoClassDefFoundError: Failed resolution of: Lorg/jacoco/agent/rt/internal_773e439/Offlineat com.mycompany.ui.components.ListArrayAdapter.$jacocoInit(ListArrayAdapter.java)复制代码
猜测与 org.jacoco.agent 包有关，并且很大可能由于 ExoPlayer 的资源包导致的；但搜索 ExoPlayer 源码，无找到对该包的引用信息
经过查询资料，发现 jacocoInit 与 Gradle 的代码覆盖率有关，怀疑 ExoPlayer 工程打开了 testCoverageEnabled，导致打包生成的 aar 包嵌入了 jacoco 埋点；而主工程中是未开启的，导致出现异常。因此，解决思路是关闭 ExoPlayer 工程的 testCoverageEnabled。
3.解决方法
修改 ExoPlayer 源码的 build.gradle 配置文件，全局关闭 android.buildTypes.debug.testCoverageEnabled
