ActivityThread中的Android应用程序RuntimeException未能找到某些源代码？

我需要帮助解决由原生Android应用程序增加的RuntimeException问题。我无法定义导致此异常的原因。这里是堆栈跟踪和代码。这里似乎有什么问题？ActivityThread中的Android应用程序RuntimeException未能找到某些源代码？

Thread [<1> main] (Suspended (exception RuntimeException)) 
    ActivityThread.performLaunchActivity(ActivityThread$ActivityClientRecord, Intent) line: 1879  
    ActivityThread.handleLaunchActivity(ActivityThread$ActivityClientRecord, Intent) line: 1980

是整个例外呢？我没有看到你在异常中粘贴的任何代码。 – Gray

的异常堆栈跟踪+消息通常印多一点逐字到logcat的。堆栈跟踪的第一行表示当系统调用Instrumentation.newActivity（ClassLoader，String，Intent）时，活动对象不能被实例化。在logcat中，你应该能够找到的东西等。“无法实例活动<组件>：<消息>”，其中<消息>是你在非常感兴趣的东西
