Twitter Oauth Callback getOAuthRequestToken null

Question

I am using the sample for the app here https://github.com/itog/Twitter4j-android-Sample and it is working. I use the same method in my app but it return null when I at line

static final String CALLBACK_URL = "oauth://t4jsample"; [Copy the same as the Sample] requestToken = twitter.getOAuthRequestToken(CALLBACK_URL);

Here are my manifest

<activity android:name="com.my.app.SharePreviewActivity" android:screenOrientation="portrait" android:theme="@style/Theme.Fullscreen" android:windowSoftInputMode="stateAlwaysHidden|adjustPan" > <intent-filter> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.BROWSABLE" /> <data android:host="t4jsample" android:scheme="oauth" /> </intent-filter> </activity>

This is other code which I copy the same from the sample app.

private void askOAuth() { ConfigurationBuilder configurationBuilder = new ConfigurationBuilder(); configurationBuilder.setOAuthConsumerKey(CONSUMER_KEY); configurationBuilder.setOAuthConsumerSecret(CONSUMER_SECRET); Configuration configuration = configurationBuilder.build(); twitter = new TwitterFactory(configuration).getInstance(); try { requestToken = twitter.getOAuthRequestToken(CALLBACK_URL); Toast.makeText(this, "Please authorize this app!", Toast.LENGTH_LONG).show(); this.startActivity(new Intent(Intent.ACTION_VIEW, Uri .parse(requestToken.getAuthenticationURL()))); } catch (TwitterException e) { e.printStackTrace(); } }

After a big time struggle, I manage to find that I forgot to

Ticked the twitter jar library (silly me!)
Added security to HTTP

You need to set the minimum sdk available for your app

if (android.os.Build.VERSION.SDK_INT > 8) { StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder() .permitAll().build(); StrictMode.setThreadPolicy(policy); }

and voila it will worked.

It's better to use SocialAuth for android instead if you are just gonna use a 3rd party SDK for the development since it offers much more. Right now I think your problem is getting a developer twitter account.

I got a developer twitter account. I am using twitter4j for API as well.
