Android M-Pesa Daraja SDK Download

This is a simple Android M-PESA SDK to allow you to integrate Safaricom M-PESA API dubbed Daraja in your Android App with ease without knowing a thing. It’s easy. I promise. 🚀

This version only offers the MPESA Express (STKPush) Support.

I will be having Kotlin support soon also, as well as examples!

If you were using 1.0.0, be warned that version 1.0.2 breaks the code. Look at the updated example

Getting Started

These instructions will help you set up this library easily on your current project and working in no time. You only need a few configurations to start working!

Setting Up

To be able to use the following library, you will need to add the following gradle dependency in your build.gradle(module:app) file

dependencies {
  implementation 'com.androidstudy:daraja:1.0.2'
}

That is the basic set up needed to be able to use the library in your applications!

Daraja requires minSdkVersion Level 14 (Min Supported by Android Studio)

Permissions

If you are using this Library,don't forget the following permission:

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

That's it, you have the required permissions and ready to go!

How do I use Daraja?

Simple use cases with MPESA Express (STKPush) will look something like this:

Have a Daraja singleton instance

    @Provides
    @Singleton
    Daraja providesDaraja() {
        return Daraja.Builder(Config.CONSUMER_KEY, Config.CONSUMER_SECRET)
                .setBusinessShortCode(Config.BUSINESS_SHORTCODE)
                .setPassKey(AppUtils.getPassKey())
                .setTransactionType(Config.ACCOUNT_TYPE)
                .setCallbackUrl(Config.CALLBACK_URL)
                .setEnvironment(Environment.SANDBOX)
                .build();
    }
        
     @Inject lateinit var daraja : Daraja
        
     private fun getToken() {
        daraja.getAccessToken(object : DarajaListener<AccessToken> {
            override fun onResult(accessToken: AccessToken) {
                var token = accessToken.access_token
                
                makePaymentRequest(token)
            }

            override fun onError(exception: DarajaException) {

            }
        })
    }

    private fun makePaymentRequest(token : String) {
        var phoneNumber = ""
        var amount = "100"
        var accountReference = "2343de"
        var description = "Payment for airtime"

        daraja.initiatePayment(token, phoneNumber, amount, accountReference, description,
            object : DarajaPaymentListener{
                override fun onPaymentRequestComplete(result: PaymentResult) {
                    Toast.makeText(baseContext, result.CustomerMessage, Toast.LENGTH_LONG).show()
                }

                override fun onPaymentFailure(exception: DarajaException) {
                    Toast.makeText(baseContext, exception.message, Toast.LENGTH_LONG).show()
                }

                override fun onNetworkFailure(exception: DarajaException) {
                    //This is invoked if the error has to do with infrastructure 404 / no internet
                    Toast.makeText(baseContext, exception.message, Toast.LENGTH_LONG).show()
                }

            }
        )
    }
