How to Build

The generated code uses a few Gradle dependencies e.g., Jackson, Volley, and Apache HttpClient. The reference to these dependencies is already added in the build.gradle file will be installed automatically. Therefore, you will need internet access for a successful build.

• In order to open the client library in Android Studio click on Open an Existing Android Project.

• Browse to locate the folder containing the source code. Select the location of the MtnMOMCollection gradle project and click Ok.

• Upon successful import, the project can be built by clicking on Build > Make Project or pressing Ctrl + F9.

How to Use

The following section explains how to use the MtnMOMCollection library in a new project.

1. Starting a new project

For starting a new project, click on Create New Android Studio Project.

Here, configure the new project by adding the name, domain and location of the sample application followed by clicking Next.

Following this, select the Phone and Tablet option as shown in the illustration below and click Next.

In the following step, choose Empty Activity as the activity type and click Next.

In this step, provide an Activity Name and Layout Name and click Finish. This would take you to the newly created project.

2. Add reference of the library project

In order to add a dependency to this sample application, click on the android button shown in the project explorer on the left side as shown in the picture. Click on Project in the drop down that emerges.

Right click the sample application in the project explorer and click on New > Module as shown in the picture.

Choose Import Gradle Project and click Next.

Click on Finish which would take you back to the sample application with the refernced SDK.

In the following step first navigate to the SampleApplication > settings.gradle file and add the line include ':MtnMOMCollectionLib'

Then navigate to the SampleApplication > app > build.gradle file and add the following line implementation project(path: ':MtnMOMCollectionLib') to the dependencies section as shown in the illustration below. Also add the following packagingOptions.

packagingOptions exclude 'META-INF/LICENSE' exclude 'META-INF/NOTICE' exclude 'META-INF/DEPENDENCIES' }

Finally, press Sync Now in the warning visible as shown in the picture below.

3. Write sample code

Once the SampleApplication is created, a file named SampleApplication > app > src > main > java > MainActivity will be visible in the Project Explorer with an onCreate method. This is the entry point for the execution of the created project. Here, you can add code to initialize the client library and instantiate a Controller class. Sample code to initialize the client library and using controller methods is given in the subsequent sections.

How to Test

The generated code and the server can be tested using automatically generated test cases. JUnit is used as the testing framework and test runner.

In Android Studio, for running the tests do the following:

1. Right click on SampleApplication > MtnMOMCollectionLib > androidTest > java) from the project explorer.
2. Select "Run All Tests" or use "Ctrl + Shift + F10" to run the Tests.

Initialization

Authentication

In order to setup authentication and initialization of the API client, you need the following information.

Parameter	Description
ocpApimSubscriptionKey	TODO: add a description

API client can be initialized as following. The appContext being passed is the Android application Context.

// Configuration parameters and credentials
String ocpApimSubscriptionKey = "ocpApimSubscriptionKey";

com.mtn.momodeveloper.sandbox.Configuration.initialize(appContext);
MtnMOMCollectionClient client = new MtnMOMCollectionClient(ocpApimSubscriptionKey);

createTokenPOSTAsync

This operation is used to create an access token which can then be used to authorize and authenticate towards the other end-points of the API.

void createTokenPOSTAsync(

client.createTokenPOSTAsync(authorization, new APICallBack<TokenPost200ApplicationJsonResponse>() {
    public void onSuccess(HttpContext context, TokenPost200ApplicationJsonResponse response) {
        // TODO success callback handler
