android 监听SDCard安装和卸载的代…

// 监听类
private final BroadcastReceiver sdcardListener = new BroadcastReceiver() {


        @Override
public 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);
