API for Android Data Backup?

[X00btine]

I am still learning C++ and QT for my own. Right now, I am planning to build a data backup app for Android, such as contacts, text messages. I find this kind of app has a large user base. What kind of API should I use to create such an app?

P.S. It is quite hard to start the app from scratch. thanks

I think your problem will be that on both Android and iOS the data for each application is sandboxed away and only available to that application... unless your app asks for *all* of the permissions. Even then, it may only be possible to do on a rooted device....

Thanks for the reply. Actually I came across one app that can access phone data without root. Still can't figure out how it works.

There are many such Android backup app and software out there, like Mobiledic, Android manager, Aisoft Android File backup and more...
