由于某些原因,在Android的清单文件中添加uses-sdk字段时会导致崩溃.我以前从未发生过这种情况,但现在无法摆脱它.

清单文件的相关部分如下：

android:versionName="1.0" >

android:minSdkVersion="14"

android:targetSdkVersion="15" />

将权限线移到uses-sdk子句的上方或下方不会有任何区别,更改最低或目标版本也不会造成任何影响.不管选择什么(由于我无法返回API 8、10或任何真正的早期级别),如果文件中使用了users-sdk子句,应用程序都会崩溃.

删除它可以使其运行.

我得到的错误是默认“不幸的是[app]已停止”,并且在logcat列表中有一个相关的“致命例外：主要”错误.

任何帮助或建议,表示赞赏.

谢谢！

这是我正在研究的一本书的一个示例(或者我应该说). ?

我在下面添加了完整的logcat列表.
