Android错误位图超过VM预算

Question

我编写了一个简单的应用程序，它可以从scrollview中加载多个壁纸（20），并允许用户将它们设置为他/她的背景。它在我的设备上安装并正常工作，但用户在安装后一直报告“强制关闭”错误，不允许他们打开应用程序！我得到的唯一报告的错误是OutOfMemory错误，但它非常神秘，我不确定有什么问题！任何指导将不胜感激，谢谢！

Answer 1

这是代码真的非常糟糕的片段。您应该知道您的应用程序在设备上确实只有有限的内存部分，因此您无法一次将所有Bitmap内存加载到内存中。

1. 使用的GridView，ListView而是有很多的ImageView。
2. 将位图质量降低到合理的位置，或者可以缩放它们。
3. 正如我可以看到，你正在尝试写一些用户可以从图像列表中选择设置为WALLPAPER;我建议Gallery。
