Android Tumblr oAuth Confusion

Question

I am trying to implement the Tumblr API in an android application. I really get hung up on user authorization so that they can do things like a message and view their dashboard. I really don't understand oAuth, and the Tumblr API skips right above it. I have no idea if I should ask the user for my credentials or what to do with the ones I have or something like that. I added the Signpost library to my project, but since then I have been scratching my head. Is anyone familiar with oAuth on Android who would like to fill me up? Thank!

Answer 1

Yes, the documentation is not so good. You should first read about OAuth. Twitter has a good review.

First of all, you need a consumer key and a secret (you can get them by registering your application in tumblr). After that, you should use the URLs that Tumblr provides to get authorization from the user. Usually you will create a request URL from which you can send the user to a browser where he will log in and authorize your application. This will trigger a callback for your application and you can get the oAuth token. Save this in your application (SharedPreferences) so that you do not need to request authentication again from the user. With this token, you can interact with the Tumblr API, which requires authentication.
