SHA Fingerprint​

note

SHA-1 fingerprint is a unique key generated for your PC that can be used for signing. It is important to have in the add Firebase as we are using Google Login and OTP Login, and to authorize these logins, we need a SHA Fingerprint certificate.

Add a SHA fingerprint to Firebase:

  1. Follow these steps if you didn't initially provide a SHA certificate fingerprint for your Firebase Android app or if you need to add an additional one:

    • In your Project settings, go to the Your apps card. and Select the Firebase Android app to which you want to add a SHA fingerprint.

How to generate the SHA from Android Studio​

note

There are two types of SHA Fingerprint, Release SHA Fingerprint, and Debug SHA Fingerprint. Here we will see how to generate both types of SHA Fingerprint.

  1. Create a file in android folder of your project name key.properties if not exists.

  2. Add properties and it's value below

       storePassword=<Your JKS password>
       keyPassword=<Your JKS Key Password>
       keyAlias=<You JKS Key Alias>
       storeFile=<Your jks file location path>

  3. Add following line to your Android/app/build.gradle file above the all android block (Check if this line already exist or not)

       def keystoreProperties = new Properties()
       def keystorePropertiesFile = rootProject.file('key.properties')
       if (keystorePropertiesFile.exists())
       {
             keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
       }

  4. Now in app:build.gradle android block check for below lines if not exist Add into your Android/app/build.gradle

       signingConfigs {
          release {
          keyAlias keystoreProperties['keyAlias']
          keyPassword keystoreProperties['keyPassword']
          storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
          storePassword keystoreProperties['storePassword']
          }
       }

       buildTypes {
          release {
             signingConfig signingConfigs.release
          }  
       }

  5. Open your terminal and enter following command

       cd android
          ./gradlew signinReport

Wait for a while it will generate your SHA Copy Both SHA1 and SHA256 for variant & config Debug and Release and add to Firebase

  • Copy SHA1 and SHA256 of both "App signing key certificate" and "Upload key certificate"
  • Paste it to Firebase
Successful !!

Great! You have successfully configured the Android App Firebase for Push Notificationa and Google Social Login!
