Android Quick Start demonstration

The purpose of this demonstration is to make you experience an end-to-end flow where IBM MobileFirst Platform Foundation SDK for Android is integrated into an Android project and used to retrieve data by using a MobileFirst adapter.

To learn more about creating projects and applications, using adapters and lots more, visit the Native Android Development landing page.

Prerequisite: Make sure that you have installed the following software:

• MobileFirst Platform command line tool (download)
• Android Studio

1. Create a MobileFirst back-end project and adapter.

   • Create a back-end project in a location of your choice.

     mfp create MyProject
     cd MyProject

   • Add an HTTP adapter to the project.

     mfp add adapter MyAdapter -t http

2. Deploy artifacts to the MobileFirst Server.

   • Start the MobileFirst Server and deploy the adapter.

     mfp start
     mfp push

3. Create an Android project in Android Studio.

4. Add the MobileFirst Android SDK to the Android Studio project

   • In Project > Gradle scripts, select build.gradle (Module: app).
   • After apply plugin: 'com.android.application', add the following line:
     

     repositories {
         jcenter()
     }

   • Inside android, add the following lines:
     

     packagingOptions {
         pickFirst 'META-INF/ASL2.0'
         pickFirst 'META-INF/LICENSE'
         pickFirst 'META-INF/NOTICE'
     }

   • Inside dependencies, add the following lines:
     

     compile group: 'com.ibm.mobile.foundation',
         name: 'ibmmobilefirstplatformfoundation',
         version: '7.1.0.0',
         ext: 'aar',
         transitive: true

   • Add the following permissions to the AndroidManifest.xml file:
     

     <uses-permission android:name="android.permission.INTERNET"/>
     <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
     <uses-permission android:name="android.permission.GET_TASKS" />

   • Add the MobileFirst UI activity:
     

     <activity android:name="com.worklight.wlclient.ui.UIActivity" />

   • In Terminal, navigate to the root of the Android Studio project and add the required configuration files by running this command:
     

     mfp push

   • Implement MobileFirst adapter invocation.

     • Main Activity class

       Make sure that your MainActivity class extends the Activity class:
       

       public class MainActivity extends Activity {
       ...

       
       Add the following import statements:
       

       import com.worklight.wlclient.api.*;
       import android.util.Log;
       import java.net.URI;
       import java.net.URISyntaxException;

       Add the following lines to the onCreate method:
       

       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_main);
       final WLClient client = WLClient.createInstance(this);
       client.connect(new WLResponseListener() {
           @Override
           public void onSuccess(WLResponse wlResponse) {
               URI adapterPath = null;
               try {
                  adapterPath = new URI("/adapters/MyAdapter/getFeed");
               } catch (URISyntaxException e) {
                  e.printStackTrace();
               }
               WLResourceRequest request = new WLResourceRequest(adapterPath,WLResourceRequest.GET);
               request.send(new MyInvokeListener());
           }
           @Override
           public void onFailure(WLFailResponse wlFailResponse) {
               Log.i("MFPMyProject","Failed connecting to the MobileFirst Server: " + wlFailResponse.getErrorMsg());
           }
       });

     • MyInvokeListener class

       Add a new MyInvokeListener class.
       Add the following import statements:
       

       import com.worklight.wlclient.api.*;
       import android.util.Log;

       Paste the following lines:
       

       public class MyInvokeListener implements WLResponseListener {
           @Override
           public void onSuccess(WLResponse wlResponse) {
               Log.i("MFPMyProject","Adapter invocation response: " + wlResponse.getResponseJSON());
           }
           @Override
           public void onFailure(WLFailResponse wlFailResponse) {
               Log.i("MFPMyProject", "Adapter invocation response: " + wlFailResponse.getErrorMsg());
           }
       }

   • Final configurations

     • Create an Android Virtual Device (AVD).

   • Click Run.

     Review the LogCat view for the data retrieved by the adapter request.
