Android App connected to Firebase

Steps to config Firebase

• Create a new project in https://console.firebase.google.com
• name new firebase project
• add your app (android)
• add the app package name

    com.ernestovaldez.keyboardshortcuts

• add friendly app name (optional)
• click on Register App
• download file google-services.json

Create a RealTime database

• Go to in develop > database
• create a new realtime database and name it.
• set in the rules (without authentication)

    {
        "rules": {
            ".read": true,
            ".write": true
        }
    }

• or set in the rules (with authentication)

    {
        "rules": {
            ".read": true,
            ".write": "auth !== null"
        }
    }

• change null value by root

Create a Cloud Storage

• Go to in develop > storage
• create new storage
• define data center (if not defined previously)
• set in the rules

    rules_version = '2';
    service firebase.storage {
        match /b/{bucket}/o {
             match /{allPaths=**} {
                allow read, write;
            }
        }
    }

• create a new folder named images

Email and Google Authentication

• Go to in develop > authentication > Sing-in Method
• Enable Email/Password and Google

For Google Auth

• needs configure the SHA1 fingerprint in the Firebase project settings, to obtain it can be run a command in console:

For Debug mode:

    keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android 

for Release mode:

    keytool -list -v -keystore {keystore_name} -alias {alias_name}

example:

    keytool -list -v -keystore C:\Users\MG\Desktop\test.jks -alias test

or in Android Studio use simple step:

• Run your project
• Click on Gradle menu
• Expand Gradle app -> Tasks tree
• Double click on android -> signingReport and see the magic
• It will tell you everything on the Run tab

In the android app project

• copy the downloaded file to /app/google-services.json
• run the project
• add new shortcut and save it.
• verify in Firebase console that the shortcut was added in the realtime database
