import android.content.ComponentName;

在init()方法里，注册监听USB插拔广播

        // wangrui Monitor USB data cable plugging and unplugging broadcasts
        context.registerReceiver(mUSBReceiver, new IntentFilter("android.hardware.usb.action.USB_STATE"));

广播接收器

    // wangrui When the USB data cable is inserted, a file transfer dialog box pops up
    BroadcastReceiver mUSBReceiver = new BroadcastReceiver() 
        @Override
        public void onReceive(Context context, Intent intent) 

            boolean connected = intent.getExtras().getBoolean("connected");
            if (connected) 
                Intent intent1 = Intent.makeRestartActivityTask(
                        new ComponentName("com.android.settings",
                                "com.android.settings.Settings$UsbDetailsActivity"));
                mContext.startActivity(intent1);
            
        
    ;

三步搞定
