java - 加载图像时出现内存不足错误

Question

我想在android上加载图片

background = BitmapFactory.decodeResource(getResources(),R.drawable.hangmanbegin);    
background =  Bitmap.createScaledBitmap(background,screenx,screeny,false);

图像是 800*1280 像素，所以如果我是正确的，它应该使用大约 3MB 的内存空间？但是我的堆就在那个阶段从 15MB 增长到 29MB，所以没有窗口或上下文泄漏？

这怎么解释？ zh 你能做些什么呢？

提前致谢!

Answer 1

Bitmaps take up a lot of memory, especially for rich images like photographs. For example, the camera on the Galaxy Nexus takes photos up to 2592x1936 pixels (5 megapixels). If the bitmap configuration used is ARGB_8888 (the default from the Android 2.3 onward) then loading this image into memory takes about 19MB of memory (2592*1936*4 bytes), immediately exhausting the per-app limit on some devices.
