Hi Nick,
there is a 50mb limit for the size of the app binary.
There are only a limited number possible solutions for the size problem:
- providing a large separate data file that gets downloaded
automatically by the play store after the user installed the app. The
problem here is that space is often times a rather rare resource on android
phones. Many low end devices have only 2 or 4gb in total. If a single app
takes several hundred megs many users would complain or not even understand
why so much space is needed. So in the end i decided against this all or
nothing approach
- let the app selectively download the training data at the cost of
adding the internet permission. This is how it is now.
- let the user push the training data manually to the app by copying it
to the sd card himself. (this is currently possible but i think this
feature is too complicated for the average user)
Regarding publishing the code. I want to do this. Iam not yet sure if i
want to use the GPL or Apache 2.0.
Also since i modified tesseract and leptonica sources a bit and have
several submodules i need to write a proper build script or readme file
before releasing the sources.
If i have time i'll push something to my git hub this weekend.
Cheers
Renard
