This is my first useful Android project. I made it for my daughter, after I learned "just enough" about Android to get started. I can't say this is my best work, but it's a nice game and it is effective - she plays it and learns through it. When we started she was about 3 years old and the game was teaching her to match colors and shapes. Then I added some Hebrew letters and words, and she learned from that. Then I added English letters and words and she's learning from that. She's now almost 7 years old. The audio recordings are her voices.
The game itself is an implementation of the well known (at least in Israel) educational board game called "Ma Bamishbetzet", which is Hebrew for "What's in the square?". I named my project Matrix, coz it sounds cooler... But essentially this game is a game of fitting things into the right place in the matrix.
I'm using Java with Eclipse, so far using Android SDK version from 2013 - I haven't upgraded since I started the project. I am using the app on my Nexus 5X (Nougat) and also on my Nexus 10 (Kit-Kat?). The addition of the images seems to increase the size of the app so my emulator fails to load it at the moment. I picked the images at random and didn't bother about their size, maybe I should. But anyway, on real devices it works, so I guess it's not that big.
- When orientation changes, the game is reset
- My young son is able (and happy) to pull cards out of the screen so that they cannot be recovered.
