[Ovmsdev] Android code for OVMS

[Mark Webb-Johnson]

William,

I just got back from vacation (working from iPad, which turned out to be a hassle for searching through gigabytes of eMail). I got your copies. I'm putting the code up in a repository at the moment, and then will contact your people with details.

Thanks, Mark.

The Android project Sonny had worked on containing updates to the OVMS Android App has been accidentally deleted, and the latest updates to the code lost. The NAS backup arrangement that Sonny had in place has also failed, and there is no backup.

Primarily the settings screen, partial support for groups, and support for tablets. It is the tablet support that is causing problems with new high-res phones (as it is incorrectly identifying these as tablets) - I suspect that the settings code is the main thing we want to retain.

The code looks good, and seems to only need minor tidy-ups. But, the resources are a mess. It seems the decompile process retains code symbols, but not resource symbols. The resource IDs and tags end up as numbers.

I don't mind stepping in with the 'donkey work', but I really don't know where to start. What are those "R" class files - they look like they may be the key?
