Java 应用程序可以在模拟器上运行，但不能在真实设备上运行

我刚刚把我的应用程序上传到google play上，然后把它安装在我的安卓手机上，安卓手机运行的是安卓2.3.5。不管怎样，在模拟器上一切都运行得很好，但在真正的设备上启动时就崩溃了。有什么想法吗？这是密码

看起来您使用的是一种未在android中实现的方法。请将您的问题发布到logcat上好吗？“但在实际设备启动时立即崩溃”请显示崩溃错误消息（logcat）是否为android 2.3.5配置了仿真器？清单文件中的Min SDK是什么？如果没有logcat消息，就无法真正帮助您我没有usb连接设备进行调试模拟器中的log cat正常吗？即使它在那里工作得很好谢谢你我删除了这个方法现在我只需要等待我新上传的apk生效再次感谢tho:）
