How to create an overlay for app as an watermark in Android pragmatically?

Question

I want to make an app in which there will be a watermark that will be shown in every activity including the fragments if it exists. I want to do that programmatically, without any XML for reducing redundant and boilerplate code. The main purpose of it is that if I share an APK with anyone else then he cannot steal my APK because it contains a weird watermark everywhere.

I made a library for this to do that in a reusable way. Here is documentation on how to use it in Java and Kotlin. First, initialize it from an activity from where you want to show the watermark-

AppWaterMarkBuilder.doConfigure()
                .setAppCompatActivity(MainActivity.this)
                .setWatermarkProperty(R.layout.layout_water_mark)
                .showWatermarkAfterConfig();

Then you can hide and show it from anywhere in your app -

  /* For hiding the watermark without callback*/
  AppWaterMarkBuilder.hideWatermark() 

  /* For showing the watermark without callback*/
  AppWaterMarkBuilder.showWatermark()
