Android：OutOfMemoryError錯誤位圖

我得到錯誤java.lang.OutOfMemoryError並崩潰應用程序，同時運行應用程序從服務器下載多個圖像並存儲到SD卡。我有一些gradle的變化。屬性並更改行＃org.gradle.jvmargs = -Xmx2048m -XX：MaxPermSize = 1024m -XX：MaxHeapSize \ = 1024m -XX：+ HeapDumpOnOutOfMemoryError -Xmx1024m -Dfile.encoding = UTF-8。並試圖撥打System.gc（）;也。但一次又一次得到同樣的錯誤。如何解決這個問題。先謝謝了。Android：OutOfMemoryError錯誤位圖

這裏是我的代碼

在該行imagenObtenida = BitmapFactory.decodeStream（conn.getInputStream（），空，期權）的錯誤;

Log.e("fileUrl ", " = " + fileUrl + " ImageName = " + ImageName); 
      URL ImgUrl = new URL(fileUrl); 
      HttpURLConnection conn = (HttpURLConnection) ImgUrl.openConnection(); 
      conn.connect(); 
      int lenghtOfImage_File = conn.getContentLength(); 
      Log.e("lenghtOfImage_File ", " = " + lenghtOfImage_File); 


       System.gc(); 
       if(imagenObtenida != null) 
       { 
        imagenObtenida.recycle(); 
        imagenObtenida = null; 
       } 
       BitmapFactory.Options options = new BitmapFactory.Options(); 
       options.inTempStorage = new byte[16*1024]; 
       options.inPurgeable = true; 
       options.inSampleSize = 1; 

       imagenObtenida = BitmapFactory.decodeStream(conn.getInputStream(), null, options); 
       newFolder = new File(Environment.getExternalStorageDirectory().getPath() + File.separator + "classnkk_images"); 

       File file = new File(newFolder, ImageName);

這是我記錄錯誤
