Q:

Is there an alternative to android:largeHeap="true"

I work with a lot of bitmaps, which far exceeds the maximum capability of 
android: largeHeap = "true"

this method is obsolete, and I think will soon be closed, because it has a large number of security holes.
Now I want to find out whether there is an alternative to this command?
Write any ideas maybe your post will push me to new thought to solve this problem.

A:

Is using largeheap in Android manifest a good practice?
That being said I've just checked the docs and there's no thing such as deprecated label or warning.
If your app makes hevy usage of memory, and you don't want to request a larger heap from Dalvik optimize your app. 
Quote from @Gabe 

Use LRUCaches and lazy loading techniques to minimize the number of
  images in memory.
