Application Configurations

Make the following configurations in your mobile application before you start integrating the SDK for wallet transactions.

Organize the Setup

To organize the setup, complete the following steps:

Add dependencies in build.gradle file.

implementation 'com.google.android.gms:play-services-wallet:18.0.0'
implementation 'com.android.support:appcompat-v7:24.1.1'

Update AndroidManifest.xml to enable Google Pay API.

<application
    ...
    ...
    <!-- Enables the Google Pay API -->
    <meta-data
        android:name="com.google.android.gms.wallet.api.enabled"
        android:value="true" />

Create Request Object

The mPoint SDK provides mPoint class to create request object based on the client configuration details. The request object is required to initiate the payment process.

this._mpoint = mPoint(URL ("[CPD provided URL]"), 
        this, 
        "username",[USERNAME] 
        "password", [PASSWORD] 
        clientid, [CLIENT ID] 
        accountid, [ACCOUNT ID] 
        null, 
        context, 
        null,
        RecordMap<String, String> (),
arrayOf(ClientInfo.IDENTIFIERS.DEVICEID)
 this._mpoint.mode = mPoint.OUTPUT_MODE.NONE)
