Android bluetoothchat应用程序显示错误

我正在尝试在我的智能手机上运行一个示例蓝牙聊天应用程序（运行Android 2.3）。Eclipse中的目标构建项目使用Android API级别10

the same project includes this in the manifest:

<uses-sdk minSdkVersion="6" android:targetSdkVersion="10"  />

以及显示这些错误的logcat

检查Eclipse项目的类路径和project.properties文件，我认为它设置不正确。

请尝试使用您以前创建的常规项目中这些文件的信息。也许会有帮助。

autobot_101，谢谢你的回复，我的项目属性文件在你的项目中也显示了这个target=android-10check.project（项目文件）。有时候，你的项目可以在这个文件中使用，当在不同的计算机上使用时，您需要更改这些行以指向正确的资源。原因是：加载程序dalvik.system.PathClassLoader[/data/app/com.example.android.BluetoothChat-1.apk]中的java.lang.ClassNotFoundException:com.example.android.BluetoothChat.BluetoothChat导致此错误是什么？
