android 接收SDCcard插拔的广播

 

接收SDcard插拔广播的 Intent为隐式意图。隐式意图必须要求 IntentFilter中的各项参数匹配

 

mReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        Log.i("Loger"," Receive SDCard Mount or UnMount!");
    }
};

IntentFilter filter = new IntentFilter();
filter.addAction(Intent.ACTION_MEDIA_MOUNTED);
filter.addAction(Intent.ACTION_MEDIA_UNMOUNTED);

filter.addDataScheme("file");

registerReceiver(mReceiver, filter);
