What applications to make on Android for practice?

Question

Android

Guys, throw in the options for applications that you can write to get experience in Android !!! ToDo list - already done)) any ideas for applications, maybe there are some interactions with the camera or something else, in general, it is desirable that as many Android themes as possible be involved in the application

Answer 1

Systemwide application that turns the background into a picture from the camera. That is, you walk down the street, write SMS, read mail, select a track in the player - and see the road through the screen. And sell for $3. I would buy.

Answer 3

1. An analogue of popular software. For example, all sorts of state analyzers, etc. (they collect statistics and visualize it - for example, some kind of Wi-Fi checker with registration of the frequency of connecting to wi-fi, which can be viewed on the graph, as well as a list of routers, trust in which is determined by the number of connections to them. But this is a utility that has its cons).
2. Client-server anonymous chat with the ability to select a nickname, colors, change them, change the theme to night and day (this is a cool experience for saving settings and understanding the work of android layout drawing), system messages about new users entering the chat, etc. . the main condition, of course, is synchronization (if your nickname is red, then everyone should have your nickname red)
3. creative.
Hidden photo. It's like a regular camera, but information from the camera is not displayed on the screen, and shooting can be done, for example, with a rocker :) by the way, a great idea, maybe it will shoot a little.
You can also write a generator of useless ideas. On your side, you create a bunch of tools and features (drawing an emoji by the user), adding click sounds on that emoji (which, for example, can be recorded from a microphone and slightly processed to the ridiculous), etc. It's like a framework for users :)

Something for experience with graphics, some simple game (tetris, pacman), with more complex graphics (like shooter-scroller), and with simple graphics in 3d (rubik's cube)
