Twitter Integration in Android and Its New API v1.1

Twitter API v1 Retirement and Use Case of Use API v1.1

The Twitter REST API v1 will officially retire on June 11, 2013. So it is time now to migrate all your applications from API v1 to API v1.1.

If you are using Twitter4J jar file in your application, then simply update your application with this jar file “ twitter4j-core-3.0.3” in your libs folder of application. There is some change in the method also in this file. Here, I am showing the list of that method changed in this new jar file.

Updating Twitter4j jar File in Android Application

Step 1

Open your existing project, right click on Project folder >> property>>Java Build Path>>library>> select previous Twitter4j-core file >> click on remove

Now copy and paste Twitter4j-core-3.0.3 jar file in your existing project libs folder and do the following. Right click on Project >> properties>>java Build Path>>library>> add Jar >> choose your project libs folder >.select the Twitter4j-core-3.0.3 file and >> apply.

Step 2

After performing step one, go into your src folder source code and modify the required method if needed as per the above given table. This is the basic way to update your existing twitter integration in Android.

Now I am going to show a simple integration of Twitter in Android Step 1

You need to create the following classes and XML file for this integration:

1. TwitterHomeActivity (main class)
2. ConnectionDetector (for checking Internet connection)
3. AlertDialogManager (for Alert Message)
4. activity_twitter_home.xml (mail activity class XML)

Step 3

Use the following code for this integration:

public class AlertDialogManager {

public void showAlertDialog(Context context, String title, String message, Boolean status) {
    AlertDialog alertDialog = new AlertDialog.Builder(context).create();

    // Setting Dialog Title
    alertDialog.setTitle(title);

    // Setting Dialog Message
    alertDialog.setMessage(message);

    if(status != null)
        // Setting alert dialog icon
        alertDialog.setIcon((status) ? R.drawable.success : R.drawable.fail);

    // Setting OK Button
    alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
        }
    });

    // Showing Alert Message
    alertDialog.show();
}}

public class ConnectionDetector {

private Context _context;

public ConnectionDetector(Context context){
    this._context = context;
}
public boolean isConnectingToInternet(){
    ConnectivityManager connectivity = (ConnectivityManager) _context.getSystemService
					(Context.CONNECTIVITY_SERVICE);
      if (connectivity != null)
      {
          NetworkInfo[] info = connectivity.getAllNetworkInfo();
          if (info != null)
              for (int i = 0; i < info.length; i++)
                  if (info[i].getState() == NetworkInfo.State.CONNECTED)
                  {
                      Log.d("Network", "NETWORKnAME: "+info[i].getTypeName());
                      return true;
                  }
      }
      return false;
}}

Android Manifest file looks like this:

<?xml version="1.0" encoding="utf-8"?>

<uses-sdk
    android:minSdkVersion="6"
    android:targetSdkVersion="8" />
<!-- Permission - Internet Connect -->
<uses-permission android:name="android.permission.INTERNET" />

<!-- Network State Permissions -->
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.sks.twitter.TwitterHomeActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        <intent-filter>
            <action android:name="android.intent.action.VIEW" />

            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />

            <data
                android:host="t4jsample"
                android:scheme="oauth" />
        </intent-filter>
    </activity>
</application>

Activity_twitter_home.xml looks like this:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

<TextView
    android:id="@+id/textView1"

    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"
    android:layout_marginLeft="106dp"
    android:layout_marginTop="21dp"
    android:text="@string/hello_world"
    android:textColor="#A52A2A"
    android:textStyle="bold"
    android:typeface="serif" />

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@+id/textView1"
    android:layout_below="@+id/textView1"
    android:layout_marginTop="80dp"
    android:text="Login to twitter" />

<EditText
    android:id="@+id/editText1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
    android:visibility="gone"
    android:ems="10" />

<Button
    android:id="@+id/button2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@+id/editText1"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="34dp"
    android:visibility="gone"
    android:text="Tweets" />

Finally, TwitterHomeActivity code is as given below:
