我得到一个java.lang.NoClassDefFoundError

Question

它和我在这里询问的程序相同.我解决了这个问题,但现在当我启动它时,它会崩溃并获得:

W/dalvikvm(  316): Unable to resolve superclass of Lcom/wingdom/convention/Map; (12)
W/dalvikvm(  316): Link of class 'Lcom/wingdom/convention/Map;' failed

该应用程序有3个活动类,TabWidget,Schedule和Map(Map实际上是MapActivity,但它现在是空白,希望应用程序首先运行).TabWidget几乎就是android开发者网站上给出的HelloTabWidget学习示例.时间表只是一个文本列表.如果您需要查看任何代码来帮助修复它,请询问.提前致谢!

Answer 1

<uses-library android:name="com.google.android.maps" />

确保将此作为应用程序的子项添加到清单中.这将阻止崩溃.

您还需要将Internet权限添加为清单的子项.

<uses-permission android:name="android.permission.INTERNET" />
