Question

What I Have Tried:

I already have registered an app in twitter and got Consumer Key and Secret.Even I got various codes to login with twitter.These are what I have tried from:

Problem I have:

Till now,above code takes me to twitter login and let me sign in and have a PIN to complete the login process.But I have no idea how to use it to get my app working.I checked the whole code but found nothing related to pin.

Secondly,when I registered my app on twitter,it asked for Callback URL but as it was written that its really not needed,i skipped specifying.(Even I don't know what it should be!)

And hence,I am giving null as CallbackURL in my app.

Can anyone suggest me,how can I use this PIN to complete login process and get user back to my app's main activity? Is it the callback url which is causing problem or something else I am doing wrong at?

Please reply.Any help appriciated! Thanks.

EDIT :

As suggested by Frankenstein,I tried code at github.com/ddewaele/AndroidTwitterSample/downloads

I added my consumer key and consumer secret along with callback url:

public static final String OAUTH_CALLBACK_SCHEME= "x-oauthflow-twitter";
public static final String OAUTH_CALLBACK_HOST= "callback";
public static final String OAUTH_CALLBACK_URL= OAUTH_CALLBACK_SCHEME + "://" + OAUTH_CALLBACK_HOST;

but it gives me this error:

Logcat:

Omg,I am going to be crazy...have been trying since two days! :( please help.

Answer 1

It's because your app is registered as a desktop client. To overwrite callback URL, your app need to be registered as a browser client.

Try configuring a dummy callback URL (http://example.com/ or whatever you want) at https://dev.twitter.com/apps/[appid]/settings > Callback URL and your app will be recognized as a browser client.

Then try @Frankenstein or @jamn224 code.
