Show modal after installation or update of app [closed]

Question

A lot of Android apps now display a modal with the most recent changelog after it is installed or updated.

How can I display a scrollable modal after the application is initially installed or updated?

Answer 1

Try this:

With Android Change Log you can easily create, show and maintain an Android change log dialog.

Features are:

• display only what's new or the whole change log
• display on first start of newly installed app or new app version
• write the change log in a simplified language but also use HTML and CSS if needed...
