VM預算我已經開發了一個機器人example.here我得到了以下錯誤：

java.lang.OutOfMemoryError: bitmap size exceeds VM budget

這裏我的控制檯窗口顯示以下錯誤：

這是我的位圖代碼：

private Bitmap getBitmap(String url) 
{ 
    File f=fileCache.getFile(url); 

    //from SD cache 
    Bitmap b = decodeFile(f); 
    if(b!=null) 
     return b; 

    //from web 
    try { 
     Bitmap bitmap=null; 
     URL imageUrl = new URL(url); 
     HttpURLConnection conn = (HttpURLConnection)imageUrl.openConnection(); 
     conn.setConnectTimeout(30000); 
     conn.setReadTimeout(30000); 
     conn.setInstanceFollowRedirects(true); 
     InputStream is=conn.getInputStream(); 
     OutputStream os = new FileOutputStream(f); 
     Utils.CopyStream(is, os); 
     os.close(); 
     bitmap = decodeFile(f); 
     return bitmap; 
    } catch (Exception ex){ 
     ex.printStackTrace(); 
     return null; 
    } 
} 

//decodes image and scales it to reduce memory consumption 
private Bitmap decodeFile(File f){ 
    try { 
     //decode image size 
     BitmapFactory.Options o = new BitmapFactory.Options(); 
     o.inJustDecodeBounds = true; 
     BitmapFactory.decodeStream(new FileInputStream(f),null,o); 

     //Find the correct scale value. It should be the power of 2. 
     final int REQUIRED_SIZE=70; 
     int width_tmp=o.outWidth, height_tmp=o.outHeight; 
     int scale=1; 
     while(true){ 
      if(width_tmp/2<REQUIRED_SIZE || height_tmp/2<REQUIRED_SIZE) 
       break; 
      width_tmp/=2; 
      height_tmp/=2; 
      scale*=2; 
     } 

     //decode with inSampleSize 
     BitmapFactory.Options o2 = new BitmapFactory.Options(); 
     o2.inSampleSize=scale; 
     return BitmapFactory.decodeStream(new FileInputStream(f), null, o2); 
    } catch (FileNotFoundException e) {} 
    return null; 
    }

請幫我解決這個錯誤。

檢查圖像分辨率和CONVER成低分辨率，您可以使用PNG文件類型...並 – Hemant

退房此developer.android鏈接： http://developer.android.com/training/displaying-bitmaps/load-bitmap.html –

您只需要更仔細地進行搜索。

這是最好的IMO，link這可能有助於回答你的問題。

謝謝你的答案。這對我真的很有幫助 – user1859172

您可以修復使用opts.inSampleSize=2; or opts.inSampleSize=4（question）

BitmapFactory.Options opts = new BitmapFactory.Options(); 
opts.inSampleSize=2; 
Bitmap bitmap = decodeFile(f,opts);`

問題也是本文提供了一些提示，可以幫助：

-這是位圖的一個常見問題，這是在加載位圖導致內存超出界限時引起的。
