AutoScrollViewPager | A ViewPager that can scroll

After doing some R&D and doing work on suggestions, Our app is 50-70% (Depending on RAM on different devices) performing better as per before.

I raised some points for the issue, I configure that:

• Is this caused due to any module or library??

Some modules make our APK size a little bit large at the time of debugging. So, if we apply progaurd or use bundle then our app APK will become less in size and will also take less RAM at that time.

• Using too many images in nested recycler views like Playstore.

Use the famous libraries for image loadings like glide or Picasso, we need bitmap pooling for images which we are using again and again. This will help us to avoid more and more bitmaps for the same image URLs

• Using AutoScrollViewPager with 1.5 secs of delay

Here is the major issue that comes, after using the app for 3-5 mins, GC calls so frequently, and that is due to ViewPager.setCurrentItem(). For the whole application where we are using ViewPager and changing pages GC calls.

In AutoScrollViewPager there is a delay with 1.5 secs and then ViewPager AutoScrolls, then GC calls. That's why there are too many GCs in the android profiler after every 2 secs.

So, we removed the code for AutoScrolling, performance is better from the last scenario.

Some other optimizations are:

• Replaces multiple instances to singleton instances.
• Removed all Leaks from the application.

Any suggestions for this issue will be helpful for all. Thank you
