//usb插入監聽 新增廣播過濾意圖


intentfilter filter = new intentfilter();


filter.addaction("android.hardware.usb.action.usb_device_attached");


filter.addaction("android.hardware.usb.action.usb_device_detached");


filter.addaction("android.hardware.usb.action.usb_state");


registerreceiver(musbbroadcastreceiver, filter);


//boolean為成員變數，自己隨便起乙個就行


broadcastreceiver musbbroadcastreceiver = new broadcastreceiver() 


if (action.equals("android.hardware.usb.action.usb_device_detached")) 


}//判斷儲存usb


if (action.equals("android.hardware.usb.action.usb_state")) else }}


//判斷耳機 


if (action.equals("android.intent.action.headset_plug")) 


} if (intextra == 1) 


if (inttype == 1) 


} } 


boolean = true;}};
最後廣播在ondestory裡面unregister一下就行

private


void


setbroadcast(long restflow) 


ctrl+r進入命令列介面後按照如下格式傳送廣播


"adb shell am broadcast -a 你的廣播 "
