Question

我开发了一个android应用程序，它首先完美地工作了几天。但后来，当我检查时，它不起作用。现在当我以前在我的设备或模拟器中启动它时，它会显示消息，如应用程序xyz意外停止。请再试一次。有人可以帮助我吗？

这是我的Logcat

Answer 1

您的应用有一个BUG。

检查LogCat以查看会发生什么，也许这是未经处理的例外。

Answer 2

尝试

在清单文件中添加“uses-library”。

     <manifest xmlns:android="http://schemas.android.com/apk/res/android"
     package="com.example.package.name">
      ...
      <application android:name="MyApplication" >
        <uses-library android:name="com.google.android.maps" />
        ...
      </application>
     ...
    </manifest>

清理并重建您的项目并试用。

如果这不起作用，请尝试添加一些代码，以便我们可以查看。

应用程序xyz意外停止了。请再试一次
