我的Android应用中出现“找不到源”并导致程序崩溃的错误。我已经阅读了很多帖子说解决方案是下载android源代码并在Eclipse中加载，但我试着无济于事。
以下是一些可能对我的问题有所帮助的信息，如果您需要更多信息，请告诉我们！
堆栈：
Thread [<1> main] (Suspended (exception RuntimeException))

第一个条目是'ActivityThrea d'并且'd'被截断是不是很奇怪？如果这是问题，出了什么问题，我该如何解决？
调试停止的代码行：
public void AddAnimationID(String index, Integer view)
{
animations.put(index, view);
}
'animations'是一个词典，是Alien类的成员。我称之为：
Alien alien;
alien.AddAnimationID("idle", R.drawable.idle);
我认为R.drawable.idle是一个int对吗？ findViewByID为参数获取一个int ...
这是logcat，我试图查明它在日志中启动应用程序的位置，对不起，如果它太多了。

我在Windows 7 x64上使用Eclipse。我拥有Android SDK的所有最新更新，我下载了android源代码，并将其添加到Eclipse补丁中，因为以前的帖子让我尝试了。调用第一次AddAnimationID时，代码会中断调试。我希望这就是你需要的一切，谢谢！对不起，顺便说一下我做错了，我对此有些新意。
编辑：看起来我没有足够的断点，罪魁祸首不是AddAnimationID函数，而是实际上是SetImageView函数。 if语句似乎不起作用，所以我暂时评论它。一旦我弄明白，我会回复。它可能是一种愚蠢的东西，适用于另一种语言而不是Java ......

问题最终成为了Dictionary类，我通过投入一堆try / catch块来模糊地工作，但这不是我想要的，所以我用Map替换它并且它工作正常。
要添加一些我从那时以来发现的有用信息到这个答案，因为有相当多的人访问过这个页面：Eclipse会在您的应用程序中发出的几乎每个随机错误都会说“Source not found”。以下是为了找到这些麻烦的代码行而要遵循的一些步骤：
1）逐行浏览代码（使用步骤过滤器忽略您未编写的代码），直到找到有问题的行，这很可能是您犯错误的地方。如果代码中的错误很深，请在您认为问题发生的位置靠近但不是之后放置一个断点，并从那里开始。
2）有时可以在“变量”面板中找到未捕获的异常和其他有用信息。
3）“未找到源”仅表示生成异常的代码行在二进制文件中。它确实存在，Eclipse无法向您显示它。

我的项目中有同样的问题，引用了一个库项目。问题的原因是图书馆项目中存在的一项活动，我忘记在我的项目manifest.xml文件中提及它。
