Question

每次尝试启动我的应用时，都会显示以下错误：

The application SMSbackupv1 (process com.SMS.Backup) has stpped unexpectedly. please try again.

我不知道错误在哪里创建。但是当我调试文件时，threadGroup.class显示并显示

Source not found
the JAR file C:\Program Files (x86)\Android\android-sdk\platforms\android-8\android.jar has no source attachment.

这是代码：

可能的堆栈跟踪？：

提前谢谢。

Answer 1

当您调试.xml文件中缺少的应用程序时，会收到此类型警告。这可能是您的布局文件或清单文件。仔细检查你的.xml文件如果您能看到logcat，那么您可以轻松找到问题。

例如：找不到源并打开Instrumentation.class 然后它可能你没有在android清单文件中添加你的活动类

Answer 2

这是我们很多人面临的问题，这个问题可能不仅适用于测试应用，也适用于您在设备上安装的应用。如果开发人员为特定布局设计应用程序或者没有更改所有布局的XML，则会在某些设备中引发错误。

Android有4个布局（我们大多数人都知道）

布局布局小布局大布局XLARGE

我的问题是我在支持2.7英寸的layout-small文件夹中对XML文件进行了更改。我跑了Emulator，再次为2.7英寸并且工作得非常好。现在，当我导出已签名的应用程序并在设备中进行测试时，它将失败。原因是我没有在Layout文件夹中进行必要的更改。我的设备期望在main.xml文件中为layout -small而不是在安装的布局版本中进行计算的某些字段。所以你应该做几件事。 1）测试应用程序时，只创建一个文件夹（包含所有xml文件的布局），这样您就可以在所有设备上测试应用程序的功能。 2）如果您已创建所有布局文件夹，然后在任何XML文件中进行更改，请确保将更改（级别）级联到所有文件夹。

快乐发展......
