Android 开发者控制台中的神秘堆栈跟踪(位图大小超过 32 位)

问题描述

我在开发者控制台中得到以下堆栈跟踪.有些报告说应用程序无法启动"或启动时崩溃".

I'm getting the following stacktrace in the developer console. Some report say "the application won't start" or "crash at startup".

我不知道该怎么做，它在我的应用程序类中没有提及任何内容！有人遇到同样的错误并找到了解决方法吗?

I don't know what to do, it doesn't mention any on my app's class! Anyone got the same error and found a fix?

推荐答案

如果是数量问题，你必须回收您的位图.
如果是大小问题(您不能加载太大的图像)，则必须加载位图的较轻副本.

if it 's a matter of quantity, you have to recycle your bitmaps.
if it's a matter of size (you can't load too big images), you have to load a lighter copy of your bitmap.

这是创建较小图像的代码

Here is the code to create a smaller image

Options thumbOpts = new Options();
thumbOpts.inSampleSize = 4;
Bitmap bmp = BitmapFactory.decodeFile(imagePath, mThumbOpts);

inSampleSize 设置为 > 1 的值, 请求解码器对原始图像进行二次采样，返回较小的图像以节省内存.
使用 2 的幂以提高效率.

inSampleSize set to a value > 1, requests the decoder to subsample the original image, returning a smaller image to save memory.
Use a power of 2 for it to be more efficient.
