Implemented:
Background Animations
- Blur
- Tilting the phone
- Motion of the colors on chat events (chat opening, message sending, jump to message).
- Smooth motion with custom interpolation. For the chat opening interpolation is 1f. Message sending and jump to message: interpolation factor is 0.33f.
- Four-color background.
- Safe to open chats few time and change screen orientation. Image buffers and background will be removed after screen is locked or activity is not visible for user.

Not implemented:
Editor for the animations and background
Message Bubble Animations
If you want to test background animation with other parameters feel free to use my code.
Properties of the motion, background colors, tilting reaction can be changed in the code:

Конкурсное задание выполнено не полностью — в работе не реализовано никакой функциональности, за исключением анимированного фона. Приложение не переподписано. Отметим, что фон не анимируется при переходе между закреплёнными сообщениями.

When switching to night mode on landscape orientation, the background becomes dark, and when returning to day mode, appears the default background pattern.
