Android 监控USB插拔事件和sdcard卡插拔事件

1.AndroidMainifest.xml注册监听广播

 <receiver android:name=".view.SdcardReceiver" android:enabled="true">
            <intent-filter>
                <action android:name="android.hardware.usb.action.USB_DEVICE_DETACHED" />
            </intent-filter>
            <intent-filter>
                <action android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" />
            </intent-filter>
			<intent-filter>
			      <action android:name="android.intent.action.MEDIA_MOUNTED" />
			      <action android:name="android.intent.action.MEDIA_UNMOUNTED" />
			      <data android:scheme="file" />
			</intent-filter>
       </receiver>
2.代码处理广播
public class SdcardReceiver extends BroadcastReceiver {

	@Override
	public void onReceive(Context context, Intent intent) {
		// TODO Auto-generated method stub
		  String action = intent.getAction();
	      if(action.equals(Intent.ACTION_MEDIA_MOUNTED)){
	          Log.e("MainActivity","插入sdcard");
	      }else if(action.equals(Intent.ACTION_MEDIA_UNMOUNTED)){
	          Log.e("MainActivity","拔出sdcard");
	      }else if (UsbManager.ACTION_USB_DEVICE_DETACHED.equals(action)) {
              Log.e("MainActivity", "拔出usb了");
              UsbDevice device = (UsbDevice) intent.getParcelableExtra(UsbManager.EXTRA_DEVICE);
          } else if (UsbManager.ACTION_USB_DEVICE_ATTACHED.equals(action)) {
              Log.e("MainActivity", "插入usb了");
          }
	}
}
