My Android Java Voip Messenger

This is huge proprietary program therefore I never publish it, however as usually I will publish about 1% of my code to demonstrate what I usually can doing - https://github.com/Alex1998100/myMessenger

Some features what I have included to published part:

• Start activity - using ConstraintLayout to justify 3 items to screen center using layout_constraintVertical_bias
• Start activity - handle button click events in separate class
• Start activity - open Progress bar in separate process runOnUiThread
• Start activity - using Intent to pass data to next form
• Help activity - using WebView with fit to full screen except button on the bottom, what placed to screen center
• Help activity - two way to show data on WebView - from URL and from local HTML-file
• Main activity - using dynamic tab view on the bottom, this is difference with my application My Android Java apps for SelfTesting JS skills where I used statically defined tabs form
• Main activity - using RecyclerView to provide scrolable GridView
• Main activity - using DataAdapter to pass data to RecyclerView
• Main activity - using itemLayout with LinearLayout to combine icon and text
• Main activity - using RandomMessageItemAdapter to generate random text and random cons from predefined icon set
• Main activity - using number of customized vector drawable icon based on standard Android icons

As I mention, this is demo application what I make as fork of my real application. Goal of this publishing, as any other of my posts, is only take opportunity to beginners to learning and also demonstrate what I can usually doing in my real application.
