android 监听SDCard安装和卸载的代码片段（测试通过）

  // 监听类private final BroadcastReceiver sdcardListener = new BroadcastReceiver() {@Overridepublic void onReceive(Context context, Intent intent) {String action = intent.getAction();Log.d("TAG", "sdcard action:::::" + action);if(Intent.ACTION_MEDIA_MOUNTED.equals(action)|| Intent.ACTION_MEDIA_SCANNER_STARTED.equals(action)|| Intent.ACTION_MEDIA_SCANNER_FINISHED.equals(action)){// SD卡成功挂载} else if(Intent.ACTION_MEDIA_REMOVED.equals(action)|| Intent.ACTION_MEDIA_UNMOUNTED.equals(action)|| Intent.ACTION_MEDIA_BAD_REMOVAL.equals(action)){// SD卡挂载失败}}};        // 注册监听private void registerSDCardListener(){IntentFilter intentFilter = new IntentFilter(Intent.ACTION_MEDIA_MOUNTED);intentFilter.addAction(Intent.ACTION_MEDIA_SCANNER_STARTED);intentFilter.addAction(Intent.ACTION_MEDIA_SCANNER_FINISHED);intentFilter.addAction(Intent.ACTION_MEDIA_REMOVED);intentFilter.addAction(Intent.ACTION_MEDIA_UNMOUNTED);intentFilter.addAction(Intent.ACTION_MEDIA_BAD_REMOVAL);intentFilter.addDataScheme("file");registerReceiver(sdcardListener, intentFilter);}

使用完成后注销监听：

unregisterReceiver(sdcardListener);
