android - 创建位图时内存不足异常 [英] android - out of memory exception when creating bitmap

问题描述

第二次创建位图后出现以下错误:

I am getting the following error after creating bitmap second time around:

04-17 18:28:09.310: ERROR/AndroidRuntime(3458): java.lang.OutOfMemoryError: bitmap size exceeds VM budget

this._profileBitmap = Bitmap.createBitmap(_profileBitmap, xCoor,  yCoor, width, height);

来自日志:

04-17 18:27:57.500: INFO/CameraCropView(3458): Original Photo Size: W 1536 x H 2048   
04-17 18:28:06.170: INFO/CameraCropView(3458): xCoor: 291   
04-17 18:28:06.170: INFO/CameraCropView(3458): yCoor: 430    
04-17 18:28:06.170: INFO/CameraCropView(3458): Width: 952  
04-17 18:28:06.170: INFO/CameraCropView(3458): Height: 952  

由于图像很大，我得到了错误.但有趣的是第一次不会发生错误，只有在我第二次拍照时才会发生，这让我相信这个 profileBitmap 没有被破坏.我该如何清理?

Since the image is huge I get the error. But the interesting thing is the error does not happen the first time, only when I take the picture the second time, which makes me believe this profileBitmap is NOT destroyed. How do I clean this up?

推荐答案

我遇到了同样的问题并通过以下方式解决:

I had the same problem and fix it this way:

我的应用程序大小约为 18MB，当我看到还有多少可用内存时，我感到震惊 - 654KB(在 1GB RAM 上！).所以我只是从项目中删除了几乎所有的图片，并在第一次启动时从互联网上下载它们，并在需要时使用 SD 卡中的图片.

My app was ~18MB size, and when I see how much memory left free I was shocked - 654KB (on 1GB RAM!). So I just deleted almost all images from project and downloaded them from the internet on first start, and use pics from SD card when needed.

要检查您的应用使用的总内存/可用内存:

To check total/free memory for your app use:

 Runtime.getRuntime().totalMemory();
 Runtime.getRuntime().freeMemory();

我忘记了主要内容 - 在您的清单中添加应用程序标签之间的这一行:

I forgot the main thing - add in your manifest, between application tag, this line:

android:largeHeap="true"
