Axway Appcelerator Titanium Alloy Application Boilerplate for Apple Touch ID and Google Fingerprint implementation

This is a boilerplate for Apple Touch ID and Google Fingerprint implementation in your Ti Alloy application.

The idea is to have this as a sample and a boilerplate for building applications using those technologies.

iOS Demo	Android Demo

Dependancies (all included)

Ti.Identity
ti.androidfingerprintalertdialog for Android Fingerprint Dialogs
Bencoding.Securely to store login credentials securely on Android (replace Apple KeyChain)

Requirements

Ti SDK 6.3.0.GA+
All dependancies.

Usage

Once cloned, you can run appc new --import --no-service to initialise your tiapp.xml file with a valid app GUID.

Don't forget to add the following to your tiapp.xml too:

For iOS Touch ID, at the root of the file:

<property name="touchid.team_id" type="string">YOU_TEAM_ID</property>

This is so you can build and run this on iOS devices too.

YOUR_TEAM_ID can be found here once logged in.

From there, you should be ready to build and test the boilerplate.

Note: For some reason, Ti.Identity.isSupported() always returns false on an Android Virtual Device but it works pretty well on a real device.

Installation

Here I'm going to list down all the things you will want to have a look at while porting this boilerplate into your application.

`tiapp.xml`

<android ...>
    <manifest ...>
        ...
        <!-- Fingerprint Permissions -->
        <uses-permission android:name="android.permission.USE_FINGERPRINT"/>
        ...
    </manifest>
</android>

<modules>
    <module platform="android" version="1.0.0">ti.identity</module>
    <module platform="android" version="3.1.0">bencoding.securely</module>
    <module platform="iphone" version="1.0.1">ti.identity</module>
</modules>

Install the required modules

ti.identity for both iOS and Android.
bencoding.securely for Android only.

Install the required Alloy assets

ti.androidfingerprintalertdialog Widget for Android only. Don't forget to add the dependancy to your app/config.json file.

Our FingerprintIdentity CommonJS library lib/fingerprint-identity.js is a wrapper to give you easy-to-use functions to call.

It also supports authentication capabilities if you're planning to use Touch ID or Fingerprint with a login functionality.

Initialise it in your app/alloy.js:

// Init the library
var FingerprintIdentity = require("fingerprint-identity");
Alloy.Globals.fingerprintIdentity = new FingerprintIdentity();

app/controllers/index.js is a good example of what you can easily do with fingerprint-identity.

Our login setup example is what you could use with an API for example. You could ask for an access_token only valid for a fingerprint login.

Here we simply accept a password input but it would be exactly the same thing with an API call.

No matter what, we securely store it (the password or token) using either the iOS KeyChain or AES Encryption using Bencoding.Securely on Android.
