FIDEL Android SDK

This SDK helps you to add card linking technology to your Android apps in minutes. It captures credit/debit card numbers securely and links them to your programs.

Install with Jitpack

Add jitpack.io to your root build.gradle at the end of repositories:

allprojects {
	repositories {
		...
		maven { url 'https://jitpack.io' }
	}
}

And finally add Fidel dependency

dependencies {
    compile 'com.github.FidelLimited:android-sdk:1.2.1'
}

Manual setup

You can manually download FidelSDK.aar and import it as a new .jar/.aar module with File / New Module / Import .JAR/.AAR package command.

And add the following dependencies:

implementation 'io.card:android-sdk:5.5.1'
implementation 'com.google.android.gms:play-services-auth:16.0.0'

Then add a new Fidel SDK module to your project.

Sample code

First, set up a programId and an apiKey (can be found in your dashboard):

Fidel.programId = "your program id";
Fidel.apiKey = "your api key";

You can pass additional data with org.json.JSONObject:

JSONObject jsonMeta = new JSONObject();
try {
    jsonMeta.put("id", "this-is-the-metadata-id");
    jsonMeta.put("customKey1", "customValue1");
    jsonMeta.put("customKey2", "customValue2");
}
    catch(JSONException e) {
    Log.e(Fidel.FIDEL_DEBUG_TAG, e.getLocalizedMessage());
}

Then, present the Fidel activity:

Fidel.present(YourActivityClass.this);

To automatically start credit card scanning, use:

Fidel.autoScan = true;

You can retrieve a card object, in case a card is successfully added:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if(requestCode == Fidel.FIDEL_LINK_CARD_REQUEST_CODE) {
        if(data != null && data.hasExtra(Fidel.FIDEL_LINK_CARD_RESULT_CARD)) {
            LinkResult card = (LinkResult)data.getParcelableExtra(Fidel.FIDEL_LINK_CARD_RESULT_CARD);

            Log.d("d", "CARD ID = " + card.id);
        }
    }
}

You can customize the topmost banner image:

Fidel.bannerImage = Bitmap(...);

If you don't set a banner, we'll just free up the space reserved for it on the top of screen.

For customizing the checkbox consent, please use the following APIs:

Fidel.companyName = "Your Company Name Inc."; //(Maximum 60 characters);
Fidel.privacyURL = "https://yourcompany.com/privacyURL"; //(must be a valid URL)
Fidel.deleteInstructions = "Your delete instructions"; //(Maximum 60 characters);

The default for companyName is "Company Name". The default for deleteInstructions is "going to your account settings".

Default country

Set a default country the SDK should use with

Fidel.country = Fidel.Country.UNITED_KINGDOM;

When you set a default country, the card linking screen will not show the country picker UI. The other options, for now, are: .UNITED_STATES, .IRELAND, .SWEDEN, .JAPAN.

Documentation

In test environment use our VISA and Mastercard test card numbers:

VISA: 4444000000004*** (the last 3 numbers can be anything)

Mastercard: 5555000000005*** (the last 3 numbers can be anything)

Possible errors

If you configured Fidel correctly, you will not receive errors after presenting the Card Linking activity. However, we respond with some suggestive errors in case something goes wrong. Please make sure that you test the integration manually as well. It's best to make sure that you configured everything correctly in your app.

In case something is not configured correctly, after attempting to present the Fidel card linking activity, you can also subscribe for checking for any errors:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
	if(requestCode == Fidel.FIDEL_LINK_CARD_REQUEST_CODE) {
		if(data != null && data.hasExtra(Fidel.FIDEL_LINK_CARD_RESULT_CARD)) {
			LinkResult linkResult = data.getParcelableExtra(Fidel.FIDEL_LINK_CARD_RESULT_CARD);
			LinkResultError error = linkResult.getError();
			if (error != null) {
			    Log.e("Fidel Error", "error message = " + error.message);
			}
		}
	}
}

In case an error is encountered we send a LinkResultError object with the LinkResult object. Retrieve the LinkResultError object by calling linkResult.getError() as demonstrated above.

The LinkResultError object

The LinkResultError object has the message and errorCode properties which might be useful for you. The errorCode property has the following codes:

public enum LinkResultErrorCode {
    USER_CANCELED,
    INVALID_URL,
    STRING_OVER_THE_LIMIT,
    MISSING_MANDATORY_INFO
}

• USER_CANCELED - Sometimes it's useful to know if the user canceled the card linking process so please check for this error, if that's the case.
• INVALID_URL - If you provide an invalid Fidel.privacyURL, you will receive this error. Please make sure your URL matches the Patterns.WEB_URL pattern.
• STRING_OVER_THE_LIMIT - We send this error in case your Fidel.deleteInstructions or Fidel.companyName exceed 60 characters.
• MISSING_MANDATORY_INFO - Some of the mandatory information necessary to configure the SDK were not provided. The following are the mandatory info you need to provide:
  1. Fidel.apiKey
  2. Fidel.programId
