Android 开发者控制台中的神秘堆栈跟踪(位图大小超过 32 位) [英] Mysterious stacktrace in Android developer console (bitmap size exceeds 32bits)

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.
