Activity.class - 类文件编辑器：JAR文件c：\ sdk \ platforms \ android-17 \ android.jar没有源附件

时间：2013-09-10 19:12:51

标签： java android eclipse jar

由于某些原因，在我的调试器中打开了一个标签为Activity.class的新标签页，其中 标题说明 ：Class File Editor和 < em>错误陈述 ：The JAR file c:\sdk\platforms\android-17\android.jar has no source attachment。您可以通过单击下面的附加源来附加源。

从那里我尝试从我的工作区添加它但是它仍然不起作用（它现在简单地说改变附加源）

尝试以下

第1步：转到adroid-sdk安装文件夹。确保android-17

上有android-sdk/sources/文件夹

第2步：现在转到Class File Editor tab。在那里，您会看到一个标签为'Attach source code'的按钮。单击它并获取选择外部文件夹的选项。并浏览，直到你到达上面提到的android-17文件夹。选择它。它将附加源代码。

第3步：现在刷新项目。

第4步：现在再次按Activity

检查ctrl+click.的源代码

就是这样，现在您可以看到Activity的源代码。

参考attach android source

答案 1 :(得分：0)

我不确定附加正确Android源的最简单方法，但是eclipse尝试打开Activity.class的原因可能是发生了一些异常。

看看logcat。您应该能够在那里看到堆栈跟踪并找到原因，甚至不需要Android源代码。

答案 2 :(得分：0)

这种情况正在发生，因为您已到达方法onCreate的末尾。然后，控制权返回到调用Activity方法的onCreate类。如果您稍后在应用程序中尝试调试某些内容，则应在代码中稍后设置断点。但是，一旦到达onCreate方法的末尾，就没有什么可以调试了。如果你想调试实际的Android Activity类，你需要下载源代码并告诉eclipse在哪里找到它，虽然我怀疑这不是你想要做的。
