将开发过程常用的内容段做个收藏，下边资料是关于Android系统下监听SD卡的插入并读取内容的内容。

private final BroadcastReceiver broadcastRec = new BroadcastReceiver() {

    @Override
    public void onReceive(Context context, Intent intent) {
         {                
            }
             
                 ||intent.getAction().equals("android.intent.action.ACTION_MEDIA_UNMOUNTED")
                 ||intent.getAction().equals("android.intent.action.ACTION_MEDIA_BAD_REMOVAL"))
         {
         }
    }
};

IntentFilter intentFilter = new IntentFilter(Intent.ACTION_MEDIA_MOUNTED);

    intentFilter.addAction(Intent.ACTION_MEDIA_UNMOUNTED);

    intentFilter.addAction(Intent.ACTION_MEDIA_REMOVED);


    intentFilter.addAction(Intent.ACTION_MEDIA_BAD_REMOVAL);



    intentFilter.addDataScheme("file");
