Android 安卓arduino usb通信

我正在尝试在安卓4.1 cross usb上建立Arduino UNO R3和Galaxy SII之间的通信。我下面的代码示例如下所示：。不幸的是，我收到消息“应用程序已停止”，这里是LogCat错误

谁能帮帮我吗。提前感谢….

您的导入很奇怪。它应该查找android.hardware.usb.UsbManager当我从import com.android.future.usb.UsbManager更改时，我遇到了很多错误；导入android.hardware.usb.UsbManager；UsbAccessory附件=UsbManager.getAccessoryintent；错误mUsbManager=UsbManager.getInstancethis；错误UsbAccessory[]附件=mUsbManager.getAccessoryList；错误mUsbManager.requestPermissionaccessory，mPermissionIntent；好啊我只是快速搜索了一下，com.android.future.usb.UsbManager包含在谷歌API附加库中。确保此库位于项目的libs文件夹中。
