If you’re finding that app data is using up more and more of the storage capacity on your Android phone, Google has just rolled out something that is likely to help: an API that allows developers to store app data on Google Drive instead of in your phone’s flash memory.

It will also mean that data created by apps using the API will be automatically synced between device. 

The change will be completely invisible to users – it will Just Work. When an Internet connection isn’t available, data will be cached locally until it can again reach Google Drive. There will be some impact on data usage, but for most apps this is likely to be trivial.
