Android How to get the public tweets with out making user login in fabrics

I know this question is asked already . I have read the twitter fabrics sdk. and its Auth but I am so dumb in understanding it. So below is the key point what I want

What I want

1. I want to get all the tweets going on the basis of hash tag following is the example of what I want on mobile Tweets on #Wwe

2. I want that my user should not have to sign in his/her twitter account. He just see the list of tweets in my app and get him self updated.

I have followed many tutorials but they are not helping me and also read how to get tweets from here and some other link .

Please tell me which auth do I need ? and How to do all these stuff. And good link with out twitter login please??

First you need to initialize Fabric with the key and secret of your twitter app:

public void initFabric(Context context){
    if(!Fabric.isInitialized()) {       
          TwitterAuthConfig authConfig = new TwitterAuthConfig(TWITTER_KEY, TWITTER_SECRET);
          Fabric.with(context, new Twitter(authConfig));                 
    }else{
          Log.d(TAG, "Fabric already initialized");
    }
}

Just rememeber to keep your key and secret secret.

Then you can retrieve the tweets by account and hashtag in the following way:

public static TweetTimelineListAdapter retrieveTimeLineByHashtag(Context context, String hashtag){
    Log.d(TAG, "Loading tweets with hashtag " + hashtag);
    SearchTimeline searchTimeline = new SearchTimeline.Builder().query(hashtag).build();
    return new TweetTimelineListAdapter.Builder(context).setTimeline(searchTimeline).build();
}

public static TweetTimelineListAdapter retrieveTimeLineByAccount(Context context, String account){
    Log.d(TAG, "Loading tweets from user " + account);
    UserTimeline userTimeline = new UserTimeline.Builder().screenName(account).build();
    return new TweetTimelineListAdapter.Builder(context).setTimeline(userTimeline).build();
}

Also take in account that the SearchTimeline only search for recent tweets that includes your search words, so you can find that no tweets are returned. However, I couldn't find a better way to get the tweets by Hashtag using Fabric.

Edit:

public class Prueba extends AppCompatActivity {

    private static final String TAG = "TWITTER_PRUEBA";
    private ListView listView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_prueba);

        bindUI();
        initFabric(getApplicationContext());
    }

    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);

        TweetTimelineListAdapter adapter = retrieveTimeLineByHashtag(this, "#Wwe");
        listView.setAdapter(adapter);
    }

    private void bindUI(){
        listView = (ListView) findViewById(R.id.prueba);
    }

    public static void initFabric(Context context){

        Log.d(TAG, "Initializing Fabric");

        if(!Fabric.isInitialized()) {


                TwitterAuthConfig authConfig = new TwitterAuthConfig(TWITTER_KEY, TWITTER_SECRET);
                Fabric.with(context, new Twitter(authConfig));


        }else{
            Log.d(TAG, "Fabric already initialized");
        }
    }

    public static TweetTimelineListAdapter retrieveTimeLineByHashtag(Context context, String hashtag){
        Log.d(TAG, "Loading tweets with hashtag " + hashtag);
        SearchTimeline searchTimeline = new SearchTimeline.Builder().query(hashtag).build();
        return new TweetTimelineListAdapter.Builder(context).setTimeline(searchTimeline).build();
    }

    public static TweetTimelineListAdapter retrieveTimeLineByAccount(Context context, String account){
        Log.d(TAG, "Loading tweets from user " + account);
        UserTimeline userTimeline = new UserTimeline.Builder().screenName(account).build();
        return new TweetTimelineListAdapter.Builder(context).setTimeline(userTimeline).build();
    }
}

Result:
