a "better solution" you say?

heres the one i recommend to everyone around the time they hit the 2gb limit if i notice...

take /all/ of the images up to the new version and put them into an RPA file, you can include it with the standard installs easy enough and android users can manually put it into a folder to the same effect. this bypasses the android limit by reducing the contents of the APK back down to nothing but the code files for at least the one update, and only has to be done whenever it hits the APK limit.

the only catch is you do need to set up a different folder where they can drop the APKs because android some time back did the retarded thing and made it impossible to access the normal install folders without Root or external access. I have no clue how to do it, but its something that every porter on f95 im aware of does now, so you should be able to ask any of them and get the information.

though if your hitting the 2gb mark already you might also want to ask around about ways to reduce the size of the images as much as possible >.< not sure who to ask about that though since i dont know what your doing, or what the other devs are doing frankly.
