Android Twitter integration using oauth and twitter4j
I want to integrate twitter in an android application and found many tutorials. Implemented 2 of them. But after implementing, when ran the application, I came to know that
-
To illustrate my comment above, here is my final working MainActivity class. Pretty similar to the code above, the differences are :
- the internal class
OAuthAccessTokenTask, that includes the retrieval of the Oauth token and the user information - its callback
onRequestTokenRetrieved(Exception)
Also, note that to get this to work you must declare a callback url on your twitter app settings, even a phony one. It took me a few hours to figure out the way it works.
When you check the twitter4j documentation, the first pieces of code refer to a PIN code you have to get from an authorisation webpage. That's what happens when no callback url is set in your app. It's called PIN based authentication and you don't want to use it on a mobile :)

This is the working example from my code , i am using twitter4j and also you don't need to set any intent in manifest since i use webview instead of browser.
Place your consumer and secret key and you should be good to go

Have you seen the sign-in-with-twitter github project, it is based on twitter4j and implements Twitter sign in for Android.

I solved the problem. I made changes to the code I found in a tutorial to make it work. Copying the whole code here. Just replace with your
ConsumerKeyandConsumerSecret.You need to add twitter4j library to your project's

I found a good example which works well with twitter4j 3.0.3 on android. Others do not work. http://hintdesk.com/how-to-tweet-in-twitter-within-android-client/
