Twitter Login Integration - Andriod

Core Features

How it works

• User can press on Login with Twitter button from the main activity
• User will be redirected to Twitter windows where user can entered their credential for the login
• If user will enter the correct detail, app will fetch the basicdetail from the twitter and it will display on the same screen.
• You also need to create one app on twitter console which can be used in the coding for the twitter authentication.

Step 3: Click on Apps to get list of Twitter apps which you have create

Step 4: Click on Create an app to create a new Twitter App

Step 5: Click on Details button to view the App details, Key and Tokens and permissions for that app

Step 6: You can copy Consumer API Key and Consumer Secret Key and use it in your Application

Requirements

• Android JellyBean 4.1

Code Snippet

Step 1: Add twitter librabary in Gradle file to use it in code

Gradle File

defaultConfig {
    applicationId "com.twitter"
    minSdkVersion 16
    targetSdkVersion 28
    versionCode 1
    versionName "1.0"
}

dependencies {

//Twitter SDK
implementation 'com.twitter.sdk.android:twitter-core:3.1.1'
}

Step 2: onCreate() method is used to verify Twitter developer account keys.

// We will get these keys from twitter developer account app

val CONSUMER_KEY = "Your Consumer key"
val CONSUMER_SECRET = "Your Consumer secret key"


//It is intialization of twitter in onCreate() 

val config = TwitterConfig.Builder(this)
        .logger(DefaultLogger(Log.DEBUG))//enable logging when app is in debug mode
        .twitterAuthConfig(
            TwitterAuthConfig(
                CONSUMER_KEY,
                CONSUMER_SECRET
            )
        )
        //pass the created app Consumer KEY and Secret also called API Key and Secret
        .debug(true)//enable debug mode
        .build()

//finally initialize twitter with created configs
Twitter.initialize(config)

Step 3: getTwitterSession() method lets us know that Twitter sesion is active or expired

// Get result of twitter session is active or not

private fun getTwitterSession(): TwitterSession? {

    //NOTE : if you want to get token and secret too use uncomment the below code
    /*TwitterAuthToken authToken = session.getAuthToken();
    String token = authToken.token;
    String secret = authToken.secret;*/

    return TwitterCore.getInstance().sessionManager.activeSession
}

Step 4: twitterLogin() method verifies twitter login credentials and allows user to login.

// This function is use to twitter login

fun twitterLogin() {
    if (getTwitterSession() == null) {
        mTwitterAuthClient!!.authorize(this, object : Callback<TwitterSession>() {
            override fun success(twitterSessionResult: Result<TwitterSession>) {
                Toast.makeText(this@MainActivity, "Success", Toast.LENGTH_SHORT).show()
                val twitterSession = twitterSessionResult.data
                fetchTwitterEmail(twitterSession)
            }

            override fun failure(e: TwitterException) {
                Toast.makeText(this@MainActivity, "Failure", Toast.LENGTH_SHORT).show()
            }
        })
    } else {//if user is already authenticated direct call fetch twitter email api
        fetchTwitterEmail(getTwitterSession())
    }
}

Step 5: fetchTwitterEmail() fetches all necessory user details from twitter account.

// Get the twitter user details.

fun fetchTwitterEmail(twitterSession: TwitterSession?) {
    mTwitterAuthClient?.requestEmail(twitterSession, object : Callback<String>() {
        override fun success(result: Result<String>) {
            //here it will give u only email and rest of other information u can get from TwitterSession

            Log.d(TAG, "twitterLogin:userId" + twitterSession!!.userId)
            Log.d(TAG, "twitterLogin:userName" + twitterSession!!.userName)
            Log.d(TAG, "twitterLogin: result.data" + result.data)

            btnLogin!!.visibility = View.GONE
            txtViewDetails!!.visibility = View.VISIBLE
            btnLogut!!.visibility = View.VISIBLE
            var userId = twitterSession!!.userId
            var username = twitterSession!!.userName
            var email = result.data
            var token = twitterSession.userId.toString()
            var str = "Now you are successfully login with twitter \n\n"
            var tokenStr = ""
            var usernameStr = ""
            var emailStr = ""
            if (token != null || token != "") {
                tokenStr = "User Id : " + token + "\n\n"
            }

            if (username != null || username != "") {
                usernameStr = "Username : " + username + "\n\n"
            }

            txtViewDetails!!.setText("" + str + tokenStr + usernameStr + emailStr)

        }

        override fun failure(exception: TwitterException) {
            Toast.makeText(this@MainActivity, "Failed to authenticate. Please try again.", Toast.LENGTH_SHORT)
                .show()
        }
    })
}
