Verify Twitter app is logged in on Android

Question

My app I'm developing launches the official twitter app new post screen so the user can post a tweet with some extra text added in the intent. I have got this working nicely however things get a little confused if the user is not logged in with the twitter app. The app launches but the user has to sign in, once they've done that the normal twitter screen appears, if they use the back button to get back to my app the new post screen actually appears after hitting back on the twitter feed screen.

Is there any way I can check that a user is actually signed into the twitter app before trying to run the intent?

Answer 1

I think it's a Twitter app internal issue and you can't test for it.

On the other hand you could provide a Dialog warning the user for this matter with a "Do not show this dialog anymore" checkbox so he gets advised and can dimiss forever the Dialog. You could even provide instructions to authenticate insside the Twitter app in this Dialog.

I am using twitter4j lib. Here I check for the username. If the username is null then there is no user signed in , else I get the username. This user name is available in the access token which I store in shared preference.

username= mySession.getUsername();

username = (username.equals("")) ? "Not logged in" : username;

code for mySession :-

public class  MySession {
    private SharedPreferences sharedPref;
    private Editor editor;

    private static final String TWEET_AUTH_KEY = "auth_key";
    private static final String TWEET_AUTH_SECRET_KEY = "auth_secret_key";
    private static final String TWEET_USER_NAME = "user_name";
    private static final String SHARED = "Twitter_Preferences";

    public TwitterSession(Context context) {
        sharedPref = context.getSharedPreferences(SHARED, Context.MODE_PRIVATE);
        editor = sharedPref.edit();
    }

    public void storeAccessToken(AccessToken accessToken, String username) {
        editor.putString(TWEET_AUTH_KEY, accessToken.getToken());
        editor.putString(TWEET_AUTH_SECRET_KEY, accessToken.getTokenSecret());
        editor.putString(TWEET_USER_NAME, username);
        editor.commit();
    }

    public void resetAccessToken() {
        editor.putString(TWEET_AUTH_KEY, null);
        editor.putString(TWEET_AUTH_SECRET_KEY, null);
        editor.putString(TWEET_USER_NAME, null);

        editor.commit();
    }

    public String getUsername() {
        return sharedPref.getString(TWEET_USER_NAME, "");
    }

    public AccessToken getAccessToken() {
        String token = sharedPref.getString(TWEET_AUTH_KEY, null);
        String tokenSecret = sharedPref.getString(TWEET_AUTH_SECRET_KEY, null);

        if (token != null && tokenSecret != null)
            return new AccessToken(token, tokenSecret);
        else
            return null;
    }
}

Hope this will help you.
