Would someone be able to explain android fragmentation?
If I created an app using 1.5 will that app work on all devices that have version 1.5 - 3.2 (highest current version)? Or are there issues between the versions? I understand 3.0 is the tablet version so an app made for 1.5 probably won't look good, but will it work without having to create specific version targeted versions of the app?
Also, why does it take so long for some phones to get updates? Is Android so tied to specific device hardware that upgrading it is not possible without other device specific modifications? I would have expected that if a phone is able to run a new version it would get it OTA, but reading around it seems a lot of android users complain that it's taking so long to get x update or that they don't even know if they will get it.
