Android Setup


In this article, we are going to set up the TYT App’s initial setup for real-time use cases.

Setup Instructions

  • Open your project File the Android Studio IDE which is used to create the project and also it is very powerful.

Major things to do:

  1. Change the BASE_URL Variable Presented in the Constants File.

    • It just updates your server’s primary URL to access all types of API Services From the App to your Server.
    • like this

      • Note : File Location : package_name(com.tyt.client) -> utilz -> Constants
      public interface URL {
         String BaseURL = "";
  2. Change the MQTT_URL value of the Variable which is presented in the SocketHelper File which is presented in the Utils Package.

    • It is used to make a Socket Connection between APP and the Server. So Update this value very carefully with your server’s right IP Address.
    • like this

      • Note : File Location : package_name(com.tyt.client) -> utilz -> SocketHelper
        public interface URL {
        String MQTT_URL = "";
  3. Create & configure account for map using Google map & Cloud by following below documents.

    * Google Cloud console link:
    * firebase setup doc:
  4. After created & enabled the billing from google cloud & map console

    • We need to create nodes in firebase realtime database, please find the sample json database below.

    • We need to update the rules for the created firebase-realtime-database as mentioned below.

  "rules": {
    "drivers": {
      ".read": true,
    "requests": {
      ".read": true,
      ".write": true
       "SOS": {
      ".read": true,
      ".write": true
       "call_FB_OTP": {
      ".read": true,
      ".write": true
- [Sample-json](

    * call_FB_OTP node is used to configure whether the firebase otp should used or dummy otp should use for our testing purpose
  1. Download & Paste the google-services.json into the project -> app -> build folder properly to make proper communication from your App which is a client to FireBase.

    Refer below screens for creating project & setup

  1. Generate SHA-1 and SHA-256 keys from the project

    • you will be able to get these keys in two ways these are

      • Get From Gradle ( Presented in the left panel ) -> android -> signing report makes two clicks. After that copy debug and release keys from the bottom window

      • Run the below command in the terminal to get SHA keys

        • Key tool -genkey -v -keystore release.keystore -alias [your_alias_name] -keyalg RSA -keysize 2048 -validity 10000
    • Finally copy that keys and paste those in Firebase where Click Settings icon (presented right on project overview ) -> project settings -> Your App section -> SHA certificate fingerprints click add button and paste & Submit.

  2. Google cloud Setup

    • Enable below services in cloud console
      • Places API - which helps to get address while typing keys from the app

      • Some Geolocation APIs like distance matrix, geocoding, geolocations, Maps JavaScript, Maps static.
  3. Reset the version code

    • So Finally Don’t Forget to reset the version code and version name to 1(version code) and “ your own string ” (version name) in the app’s build. Gradle file which is presented inside

anndroid -> defaultConfig

versionCode 1
versionName "1.0"

And also if you change the package name from the source make sure it is updated in the same file discussed above

applicationId "com.tyt.client"
