i'v try using twitter connect plugin but it does't work 
i'v error `failed login session`
i'v also get fabric key 
so any solution for this to get twitter authentication and login with it.
this is my code:

```
loginWithTwitter(){

  this.tw.login().then(function(result) {
    console.log(result);
    //Get user data
    this.tw.showUser().then(function(user){
      //Save the user data in NativeStorage

      this.storage.setItem('twitter_user',
      {
        name: user.name,
        userName: user.screen_name,
        picture: user.profile_image_url_https
      }).then(function() {      
        console.log("twitter");
      })
    }, function(error){

  });
})

}

```

and this my config file 

```
<plugin name="twitter-connect-plugin" spec="https://github.com/chroa/twitter-connect-plugin">
    <variable name="FABRIC_KEY" value="ddb30e3efa7732b38e327c75a3ce57fd4c688ee1" />
    <variable name="TWITTER_KEY" value="twitter key" />
    <variable name="TWITTER_SECRET" value="twitter secret" />
</plugin>

```

any solutions?
