Getting Started

The following instuctions will get you a copy of the project up and running on your local machine for development and testing purpose.

Prerequisites

What things you need to install the software

1. Latest version of android studio should be set-up and running on your system.
2. Add Firebase to your project. (https://firebase.google.com/docs/android/setup)
3. And finally, an android device (or emulator) running on Jelly Bean or higher.

Setting up Firebase - You have to add your own 'google-services.json' file

By now, you would have already downloaded the "google-services.json" file and connected your app to Firebase Server. Finally, to set the server side Authentication, Realtime Database and Storage provided by Google Firebase, follow the steps below:

1. Check for the following dependencies in app-level gradle file

   implementation 'com.google.firebase:firebase-core:16.0.8'
   implementation 'com.google.firebase:firebase-auth:16.2.1'
   implementation 'com.google.firebase:firebase-firestore:18.2.0'
   implementation 'com.google.firebase:firebase-database:16.1.0'
   

2. Add the following database rules, in Firebase console:

{
  "rules": {
    
    // nobody can read/write the developer_master_key (for security purpose)
    "developer_master_key": {
      ".write": false,
        ".read": false
    },
      
    // don't allow anyone to read from user_data section
    // write is only possible if user is authenticated
    "user_data": {
      ".write": "auth != null",
      ".read": false
    }
      
  }
}

3. Add the following cloud firestore rules, in Firebase console:

service cloud.firestore {
  match /databases/{database}/documents {
  	// allow a user to modify data only under his document
    match /password_collections/{user_uid}/user_passwords/{password_id} {
      allow read, write, delete, update: if request.auth != null && request.auth.uid == user_uid;
    }
  }
}

4. For Authentication, "Phone" in Firebase should be enabled and also add your SHA1 certificate to firebase
