Africa's Talking Java SDK

Download

The SDK provides convenient access to the Africa's Talking API from applications written in Java.

Android Users: Remember your API key has to be kept secret; hard-coding it into an apk you publish is a security risk. So on Android, use the Android SDK instead.

Documentation

Take a look at the API docs here.

Install

You can depend on the .jar through Maven (from http://dl.bintray.com/africastalking/java):

<repositories>
   <repository>
      <id>africastalking</id>
      <name>AfricasTalking</name>
      <url>http://dl.bintray.com/africastalking/java</url>
   </repository>
</repositories>
...
<dependency>
  <groupId>com.africastalking</groupId>
  <artifactId>core</artifactId>
  <version>3.4.1</version>
</dependency>

or sbt:

resolvers += "africastalking maven repository" at "http://dl.bintray.com/africastalking/java"
// Get all services
libraryDependencies += "com.africastalking" % "core" % "3.4.1"

or Gradle:

repositories {
  maven {
    url  "http://dl.bintray.com/africastalking/java"
  }
}

dependencies{
  // Get all services
  compile 'com.africastalking:core:3.4.1'
}

Usage

The SDK needs to be initialized with your app username and API key, which you get from the dashboard.

You can use this SDK for either production or sandbox apps. For sandbox, the app username is ALWAYS sandbox

// Initialize
String username = "YOUR_USERNAME";    // use 'sandbox' for development in the test environment
String apiKey = "YOUR_API_KEY";       // use your sandbox app API key for development in the test environment
AfricasTalking.initialize(username, apiKey);

// Initialize a service e.g. SMS
SmsService sms = AfricasTalking.getService(AfricasTalking.SERVICE_SMS);

// Use the service
List<Recipient> response = sms.send("Hello Message!", new String[] {"+2547xxxxxx"}, true);

See example for more usage examples.

  • initialize(string username, String apiKey): Initialize the library.
