Android loads more images

This was after the improvement yesterday. I tested it and can load 50 thousand images. It is estimated that more than 50 thousand images are OK. I only tried 50 thousand images, but it is not necessary to do this, in reality, about 1000 is almost the same, but my application is almost the same as 100, package com. lanlong. test; import java. io. file; import java. lang. ref. softReference; import java. lang. ref. weakReference; import java. util. hashMap; import java. util. map; import android. app. activity; import android. graphics. bitmap; import android. graphics. matrix; import android. graphics. drawable. bitmapDrawable; import android. graphics. drawable. drawable; import android.
