Answer 1

我解决了这个问题。

问题是活动布局中的背景资源

原因======================================= 后台资源文件分辨率为482 * 290

但图像路径是可绘制的

所以我的手机dpi是xxxhdpi（mdpi * 4）

查看Allocation Tracking

中的byte [] size 8998912

482 * 4(mdpi * 4) * 290 * 4(mdpi * 4) * 4(ARGB_888 takes 4 Bytes) = 8998912

参考网站：http://gokhanarik.com/android-background-image-high-memory-usage-issue/

我知道内存大小增加的原因，但我不知道为什么没有调用GC。

如果你知道请告诉我原因..

为什么从移动活动中增加内存？
