Android：OutOfMemoryError错误位图

我得到错误java.lang.OutOfMemoryError并崩溃应用程序，同时运行应用程序从服务器下载多个图像并存储到SD卡。我有一些gradle的变化。属性并更改行＃org.gradle.jvmargs = -Xmx2048m -XX：MaxPermSize = 1024m -XX：MaxHeapSize \ = 1024m -XX：+ HeapDumpOnOutOfMemoryError -Xmx1024m -Dfile.encoding = UTF-8。并试图拨打System.gc（）;也。但一次又一次得到同样的错误。如何解决这个问题。先谢谢了。Android：OutOfMemoryError错误位图

这里是我的代码

在该行imagenObtenida = BitmapFactory.decodeStream（conn.getInputStream（），空，期权）的错误;

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);

这是我记录错误
