android 監聽SDCard安裝和卸載的程式碼片段（測試通過）

      
// 監聽類
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卡成功掛載
                
            } else if(Intent.ACTION_MEDIA_REMOVED.equals(action)
|| Intent.ACTION_MEDIA_UNMOUNTED.equals(action)
|| Intent.ACTION_MEDIA_BAD_REMOVAL.equals(action)
                    ){
// SD卡掛載失敗
                
            }

        }
    };

// 註冊監聽
    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);
    }

使用完成後登出監聽：

unregisterReceiver(sdcardListener);
