Android integration

Once done, follow these steps :

• Decompress the file.zip
• Copy the filepay-android-gateway-release.aar in the folder libs of your application
• Open the file build.gradle  of your application and modify the line
  implementation fileTree(dir: 'libs', include: ['*.jar']) to have
  implementation fileTree(dir: 'libs', include: ['*.jar','*.aar'])
• Still in the file build.gradle, add in the block dependencies the lines below :
  implementation 'com.google.code.gson:gson:2.8.5'
implementation 'com.squareup.okhttp3:okhttp:3.12.1'
implementation 'com.squareup.okio:okio:2.1.0'
implementation 'com.squareup.retrofit2:retrofit:2.5.0'
implementation 'com.squareup.retrofit2:converter-gson:2.5.0'
• Perform a gradle build to update your application

Now open the activity or fragment where the payment will take place.
Once done, follow these steps:

• • Declare the request code and plugin configuration variables by copying and pasting
    private static final int PLUS_PAYMENT_ACTIVITY_RESULT = 1102; // The plugin request code (do not change its value)
private Pay_Setup RequestSetup, ResponseSetup;


• • Initialize the plugin by copying and pasting
    String appName = "name of your mobile app";
RequestSetup = new Pay_Setup(); // initialization of the setup variable for sending
ResponseSetup = new Pay_Setup(); // initialization of the setup variable for the response
RequestSetup.setApi_public_key("Master key generated during the creation of your application");
RequestSetup.setApi_token("Token generated during the creation of your application");
// Definition of the mode of use. Either 'test' or 'live', example : RequestSetup.setMode("live") ou RequestSetup.setMode("test")
RequestSetup.setMode(" How your application works");

RequestSetup.setMethod(0);

• • Suppose your customer has purchased two items. To add these two articles to the setup, do like this :
    RequestSetup.addInvoiceitem(new Pay_InvoiceItem("Jean Gucci", 3, 150, 450, "Jean bleu, de marque Gucci"));
RequestSetup.addInvoiceitem(new Pay_InvoiceItem("Jean Prada", 2, 100, 200, "Jean noir, de marque Prada"));


• • To add the total and the description of the invoice, do like this :
    RequestSetup.setDescription("Purchase of "+ RequestSetup.getInvoiceItems().size()+" item(s) for "+RequestSetup.getTotal_amount()+" franc(s) in "+appName );
RequestSetup.setTotal_amount(650); // allows to indicate the total amount of the invoice. this amount will be deducted from the customer

• • To start the payment process, do like this :
    Intent PaymentActivity = new Intent(getApplicationContext(), pay_payment_activity.class);
Bundle PaymentActivitySetup = new Bundle();
PaymentActivitySetup.putParcelable("setup",RequestSetup);
PaymentActivity.putExtras(PaymentActivitySetup);
startActivityForResult(PaymentActivity, PAY_PAYMENT_ACTIVITY_RESULT);

• To recover the result of the payment process, do like this :
  @Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
  if (requestCode == PAY_PAYMENT_ACTIVITY_RESULT && resultCode == RESULT_OK) {
    Bundle PaymentActivitySetup = data.getExtras();
    Pay_GetReport report = PaymentActivitySetup.getParcelable("report");
    ResponseSetup = PaymentActivitySetup.getParcelable("setup");
    switch (report.getResponse_code()){
      case "00":
        if(report.getStatus() == "completed"){
          // write your successful payment code here
          Toast.makeText(getApplicationContext(),"Succes", Toast.LENGTH_SHORT).show();
        }else{
          //write your failed payment code here
          Toast.makeText(getApplicationContext(),"Echec", Toast.LENGTH_SHORT).show();
        }
        // to recover the token of this transaction, do ResponseSetup.getInvoiceToken();
      break;
      default:
        //write your failed payment code here
        Toast.makeText(getApplicationContext(),"Echec", Toast.LENGTH_SHORT).show();
        // failure pattern display
        Toast.makeText(getApplicationContext(),""+report.getResponse_text(),Toast.LENGTH_SHORT).show();
        // to recover the token of this transaction, do ResponseSetup.getInvoiceToken();
      break;
    }
  }
}
