 1 | # SIM Card Based Mobile Authentication with Android
 2 | 
 3 | How to Add SIM Card Based Mobile Authentication to your Android App with [tru.ID](https://tru.id).
 4 | 
 5 | [![License][license-image]][license-url]
 6 | 
 7 | 
 8 | ## Before you begin
 9 | 
10 | You will need:
11 | 
12 | - Android capable IDE e.g. [Android Studio](https://developer.android.com/studio)
13 | - A [tru.ID Account](https://tru.id)
14 | - An Android phone with a SIM card and mobile data connection
15 | 
16 | ## Getting Started
17 | 
18 | Install the [tru.ID CLI]() and set it up using the command provided in the [tru.ID console](https://developer.tru.id/console):
19 | 
20 | ```bash
21 | $ tru setup:credentials {client_id} {client_secret} {data_residency}
22 | ```
23 | 
24 | Install the development server plugin:
25 | 
26 | ```bash
27 | $ tru plugins:install @tru_id/cli-plugin-dev-server@canary
28 | ```
29 | 
30 | Create a **tru.ID** project:
31 | 
32 | ```bash
33 | $ tru projects:create authsome-android
34 | ```
35 | 
36 | Run the development server and take a note of the local tunnel URL:
37 | 
38 | ```bash
39 | $ tru server --project-dir ./authsome-android
40 | ```
41 | 
42 | Clone or this repo:
43 | 
44 | ```bash
45 | $ git clone git@github.com:tru-ID/sim-card-auth-android.git
46 | ```
47 | 
48 | Open the project with your Android Capable IDE.
49 | 
50 | Create a file `app/tru-id.properties` in your project and add configuration to identify the local tunnel URL of the development server:
51 | 
52 | ```
53 | EXAMPLE_SERVER_BASE_URL="https://example.com"
54 | ```
55 | 
56 | Connect your phone to your computer so it's used for running the application and run the application from your IDE.
57 | 
58 | Enter the phone number for the mobile device in the UI in the format +{country_code}{number} e.g. `+447900123456`. Press the done keyboard key or touch the "Verify my phone number" button and you will see the result of the check.
59 | 
60 | Get in touch: please email [feedback@tru.id](mailto:feedback@tru.id) with any questions.
