    @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);
