例外從Android的內存

Question

我有一個問題，從數據庫恢復圖像到Android使用類型byte []和我們傳遞ArrayList圖像到我們使用Glide的適配器，但我可以恢復超過20個圖像的數據庫使用服務Web PHP，應用程序返回異常「內存不足!!」

我希望你能幫助我找到一個解決這個problemI多試解決方案的更多，但我仍然有問題

public class CardAdapter extends RecyclerView.Adapter<CardAdapter.MyTag>

在AndroidManifest.xml添加這個標籤<Application>內：

android:hardwareAccelerated="false" 
android:largeHeap="true"
