Okay, I managed to detect the data path from previous version and migrate Data, Mp3, Saves and Maps folders and config/settings.json file. I decided to skip Mods folder though (I think it could cause problems aaand it would take more time to implement).
Edit ~ actually, the saves probably aren’t even compatible with current version, so probably they shouldn’t get migrated…
Feel free to mess with the travis file.
If you need it, generated artifacts should be in ./project/vcmi-app/build/outputs/apk/*.apk
There are still some (minor) things to solve for daily builds. Currently travis builds only one configuration (debug, api16+, armeabi-v7a). I think that ideally 2 packages should be created (release,api16,armeabi-v7a and release,api21,all abis). Changing the build to 2 packages is probably a matter of fiddling with travis config (+ less hardcoding in ./travis-extras/vcmiconf.json.in) and to build release package, we would need to add some “fake” signing to repo.
