Android 我的应用程序安装在emulator中，但引发错误：不幸的是，AppNAME已停止

我正在使用Phonegap和Cordova构建一个应用程序。当我在Eclipse emulator中运行应用程序时，apk安装成功，但单击它后，我收到一条警告：“不幸的是，AppName已停止”。任何解决此问题的指导或建议都将非常好，谢谢

ClassNotFoundException。你的应用程序找不到你的类。检查所有java文件一次。或者发布您的清单文件。

尝试转到Project->Properties->Java Build Path->Order&Export，并确保为您的项目和您正在使用的所有其他库项目检查Android私有库。之后清理所有项目，看看会发生什么。

单击按钮时是否会显示错误？

尽量避免在packagenames中混用大写和小写名称，这注定会带来麻烦。尤其是在windows计算机上开发时

---

因此，使用com.structivexgames.structivexgames代替包名com.structivexgames.structivexgames，方法是重命名包目录并替换项目每个文件中的packagename。

Android似乎无法在运行时找到所需的类或库。com.structivexgames.structivexgames.Challenger？确保libs文件夹中存在cordova.jar。在androidMainfest上添加正确的应用程序名称。xml@AmitPrajapati在清单文件中，我当前有一个问题，我是否应该将其更改为app_name，以便在清单文件中添加ComponentInfo活动。确保清单文件和活动具有相同的类名称请再次检查问题，我刚刚在问题中添加了清单文件代码。android:name=“Challenger”。首先检查你的活动名称，应该是“挑战者”。如果是挑战者，那么就把它放进去。在挑战者面前。所以它看起来像android:name=“.Challenger”。我刚刚检查过它，它们被检查过了！我没有写任何Java代码。我正在使用phonegap库，这意味着我已经用HTML、CSS和JS编码了它，而不是核心java@colourtheweb哦，对不起，我不知道电话差距。我认为您正面临这个问题，因为menifest.xml中的包名或类名与导入包名的位置不匹配。所以，请在我单击“确定”时进行交叉检查，然后什么都没有发生。所有这些错误都发生在我在模拟器中启动应用程序时。发生这种情况的原因有很多。对我来说，当我将处理按钮按下事件的代码放在onCreate（Bundle savedInstance）{…}方法而不是onCreateOptions菜单（Menu Menu）{…}中时，就会发生这种情况方法…尝试将事件处理代码移动到onCreateOptionsMenu（）方法，看看会发生什么。
