【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() {                @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);
