Android开发者控制台中的神秘堆栈跟踪(位图大小超过32位)

Question

我在开发人员控制台中获得了以下堆栈跟踪.一些报告称"应用程序无法启动"或"启动时崩溃".

我不知道该怎么做,它在我的应用程序课上没有提到任何内容!任何人都有同样的错误,并找到了修复？

Answer 1

如果这是数量问题,你必须回收你的位图.
如果它是一个大小问题(你不能加载太大的图像),你必须加载一个较轻的位图副本.

这是创建较小图像的代码

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的幂可以提高效率.
