Poor man's Family E-Album With Kindle Fire 7th 2019

This Black Friday, I grabed 2 Kindle Fire 7th 2019 by $29.99 for each. I have being watched them for about half a year just because they are at golden size for an E-Album, big enough storage for pictures, and most important, cheap enough for poor man. I only have to do a little extra work -- writing an Android app -- that can't be hard for me.
Here is how:

Download Android Studio IDE

A soooo long waiting.

Write An App with Fullscreen Activity

Have to learn Kotlin language, which is good

App Fetching Pictures From Remote Server

Be careful that Android has no too much memory.

App Has Some Animations For Picture Switching

Make my E-Album have better performance.

A Web Server Providing Pictures

So my E-Album can work when traveling.
