为什么我在.verifyCredentials（）上遇到错误

Question

I want to get the data using twitter's fabric api but whenever i tend to verify credentials and use a callback it shows an error , specifically ,"The arguments differ in length"

void getUserData() {
        Twitter.getApiClient(session).getAccountService()
                .verifyCredentials(true, false, new Callback<User>() {

                    @Override
                    public void failure(TwitterException e) {

                    }

                    @Override
                    public void success(Result<User> userResult) {

                        User user = userResult.data;
                        String twitterImage = user.profileImageUrl;

                        try {
                            Log.d("imageurl", user.profileImageUrl);
                            Log.d("name", user.name);
                            Log.d("email",user.email);
                            Log.d("des", user.description);
                            Log.d("followers ", String.valueOf(user.followersCount));
                            Log.d("createdAt", user.createdAt);
                        } catch (Exception e) {
                            e.printStackTrace();
                        }


                    }

                });


    }

Answer 1

Just change the twitter dependency in your Build.Gradle from

compile('com.twitter.sdk.android:twitter:2.0.0@aar') {
    transitive = true;
}

to

compile('com.twitter.sdk.android:twitter:1.11.0@aar') {
    transitive = true;
}

The new version of the .verifyCredentials() method doesn't accept a callback hence your error.

Answer 2

If you check the fabric documentation, it shows two version of the method, however when I tried to open the source code in Android Studio but it had only the version without the callback.

You can solve the isssue as follows:

//Getting the account service of the user logged in
Call<User> call = Twitter.getApiClient(session).getAccountService()
        .verifyCredentials(true, false);
call.enqueue(new Callback<User>() {
        @Override
        public void failure(TwitterException e) {
            //If any error occurs handle it here
        }
        @Override
        public void success(Result<User> userResult) {
            //If it succeeds creating a User object from userResult.data
            User user = userResult.data;
                    String twitterImage = user.profileImageUrl;

                    try {
                        Log.d("imageurl", user.profileImageUrl);
                        Log.d("name", user.name);
                        Log.d("email",user.email);
                        Log.d("des", user.description);
                        Log.d("followers ", String.valueOf(user.followersCount));
                        Log.d("createdAt", user.createdAt);
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
        }
    });
