我收到了java.lang.VerifyError。我发布了我的日志文件和代码。
我找了几个解决方案，其中一个是以下链接， 但没有什么对我有用。

我在清单文件中犯了错误。
我想写一下
<uses-library android:name="com.google.android.maps" />
在appilcation标签中，我所做的是，我用清单标签写了它。
所以基本上我想要遵循以下结构。
<manifest>
<uses-permission/>
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<uses-library android:name="com.google.android.maps" />

您是否设置了Android Manifest文件的权限，如下所示：
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
答案 2 :(得分：0)
我认为您使用的任何与您的设备api版本不兼容的方法意味着您在API级别低于此级别的设备（或仿真器）中使用任何更高API级别的方法。
当我在我的应用程序中使用killBackgroundProcess（）方法（在Android 2.2及更高版本中可用）并尝试在Android 1.6中运行应用程序时，我遇到了同样的错误。
希望你遇到问题。
