android - 索尼爱立信 Xperia 上的虚拟内存不足

Question

我的应用程序包含大量在运行时加载的图像。这个应用程序几乎在所有安卓设备上都能正常工作，但在 Xperia 上它经常因虚拟内存不足而崩溃。请帮助我...

Answer 1

您需要捕获低内存错误并减小下载图像的大小，如下所示。

 catch(OutOfMemoryError e)
         {
             e.printStackTrace();
             Log.e("Out of memory error", e.toString());
             reduce_size();
         }
.....

BitmapFactory.Options options=new BitmapFactory.Options();
    options.inSampleSize = 8;
    options.inJustDecodeBounds = true;

    Bitmap preview_bitmap=BitmapFactory.decodeStream(is,null,options);

    final int REQUIRED_SIZE=70;

    int width_tmp=options.outWidth, height_tmp=options.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;
    Bitmap btm=BitmapFactory.decodeStream(is, null, o2);
    img_t.setImageBitmap(btm);
