Android: Fabric User Timeline Not Working -

i followed documentation , project appeared set fine. however, when run project app displaying "no tweets' textview, not timeline. code in doc, cuz wanna see working first before else.

here's activity's oncreate:

protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_social);       try{         twitterauthconfig authconfig = new twitterauthconfig(twitter_key, twitter_secret);         fabric.with(this, new twitter(authconfig));          final usertimeline usertimeline = new usertimeline.builder()                 .screenname("fabric")                 .build();         final tweettimelinelistadapter adapter = new tweettimelinelistadapter(this, usertimeline);          setlistadapter(adapter);     }catch(exception ex){      }

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" app:layout_behavior="@string/appbar_scrolling_view_behavior" tools:context="org.witrackclub.wtc.socialactivity" tools:showin="@layout/activity_social">  <textview android:id="@id/android:empty"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:gravity="center_horizontal|center_vertical"     android:text="no tweets"/>  <listview android:id="@id/android:list"     android:layout_width="match_parent"     android:layout_height="0dp"     android:layout_weight="1"     android:divider="#e1e8ed"     android:dividerheight="1dp"     android:drawselectorontop="false"/>  </linearlayout> 

help appreciated

well, think problem keys (consumerkey & consumersecret).

androidmanifest.xml

<application     ...     android:name="timelinefabricapplication"     ... 

the application: timelinefabricapplication.java

import android.app.application; import com.twitter.sdk.android.twitter; import com.twitter.sdk.android.core.twitterauthconfig; import io.fabric.sdk.android.fabric;  public class timelinefabricapplication extends application{      @override     public void oncreate() {         super.oncreate();          twitterauthconfig authconfig =  new twitterauthconfig("consumerkey", "consumersecret");         fabric.with(this, new twitter(authconfig));     } } 

the activity: mainactivity.java

import android.app.listactivity; import android.os.bundle; import com.twitter.sdk.android.tweetui.tweettimelinelistadapter; import com.twitter.sdk.android.tweetui.usertimeline;  public class mainactivity extends listactivity {      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);          final usertimeline usertimeline = new usertimeline.builder()             .screenname("fabric")             .build();         final tweettimelinelistadapter adapter = new tweettimelinelistadapter.builder(this)             .settimeline(usertimeline)             .build();         setlistadapter(adapter);     } } 

and layout: activity_main.xml

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     android:orientation="vertical"     android:layout_width="match_parent"     android:layout_height="match_parent">      <textview android:id="@id/android:empty"         android:layout_width="match_parent"         android:layout_height="match_parent"         android:gravity="center_horizontal|center_vertical"         android:text="no tweets"/>      <listview android:id="@id/android:list"         android:layout_width="match_parent"         android:layout_height="0dp"         android:layout_weight="1"         android:divider="#e1e8ed"         android:dividerheight="1dp"         android:drawselectorontop="false"/> </linearlayout> 

my result:

the keys helped me found myself in fabric.io of created application. sure created app on fabric.io user?

in logcat or androidmonitor, see like: failed app auth token com.twitter.sdk.android.core.twitterapiexception: 403 forbidden
