USB的拔出广播消息是什么

我用的是pad ，系统3.2的 。插入消息收集到了这是我接受到的USB 插入广播 public void onReceive(Context context, Intent intent) { String action = intent.getAction(); String strTmp = ""; String actionUsbConnect = "connected"; if (action.equals("android.hardware.usb.action.USB_STATE")) { //notify usb connect if (intent.getExtras().getBoolean(actionUsbConnect)) { //success } }}USB拔出广播 我试过了android.hardware.usb.action.USB_DEVICE_DETACHED "android.hardware.action.USB_DISCONNECTED";可惜 没接收到。大神来帮个忙吧

可以参考源码:
frameworks\base\packages\systemui\src\com\android\systemui\usb\UsbStorageActivity.java

简单示例如下:

@Override
protected void onResume() {
super.onResume();
registerReceiver(mUsbStateReceiver,
new IntentFilter(UsbManager.ACTION_USB_STATE));
}

.........

private BroadcastReceiver mUsbStateReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(UsbManager.ACTION_USB_STATE)) {
boolean connected = intent.getExtras().getBoolean(UsbManager.USB_CONNECTED);
if (!connected) {
// It was disconnected from the plug, do something ...
}
}
}
};

1.插入mp3进usb接口后，再打开mp3电源。2.如果还不行，把你的小安装盘安装一下。安装盘虽小，但一样可以放到dvdrom里啊，它的使用和大小无关。假如光盘插入后没有自动运行，那就找到driver目录里的setup.exe文件双击即可安装。3.安装完后，拨出mp3再重新插入，再打开mp3开关。
