Android“应用程序意外停止” - 谷歌Hello MapView Tutoria

时间：2010-05-02 13:18:10

标签： java android

我正在尝试Hello MapView Tutorial。当我在模拟器中启动程序时，我得到了大量错误（没有任何异常似乎与我的代码中的行有关）。模拟器窗口告诉程序“意外停止”。任何人都可以告诉我哪个是错误输出中的关键线？我需要改变什么？

答案 0 :(得分：2)

  

似乎没有例外   与我的代码中的行相关

最肯定的是：

关键是：

05-02 15:05:35.395: ERROR/AndroidRuntime(201): Caused by: java.lang.ClassNotFoundException: org.diretto.client.smartphone.android.ShowMap in loader dalvik.system.PathClassLoader@4376af90

可以通过实现org.diretto.client.smartphone.android.ShowMap类或确保其超类存在来解决。

由于你正在玩地图，我猜你是在Android模拟器中尝试这个。您的模拟器AVD可能没有安装Google API，因此Android无法找到ShowMap的某些与地图相关的超类（例如MapActivity）。确保您的AVD不仅适用于Android 2.1（或其他），但其中包含Google API。
