If you’re working on Android app development, especially with Google APIs like Firebase or integrating login systems, one of the common requirements is to generate the SHA1 key from Android Studio. In this article, we will guide you step-by-step on how to generate the SHA1 key using Android Studio and solve common issues you may encounter during the process.
What is SHA1 Key and Why Do You Need It?
The SHA1 key is a unique digital fingerprint used to secure and authenticate Android applications, particularly during API integrations. It’s often required when setting up features like Firebase Authentication, Google Sign-In, or any login-related functionality that involves verifying app credentials.
Steps to Generate SHA1 Key in Android Studio
Follow these steps to generate your SHA1 key easily:
Step 1: Open Android Studio
Make sure your Android Studio is installed and the project is properly loaded. You can download Android Studio from the official website:
🔗 https://developer.android.com/studio
Step 2: Open the Terminal
At the bottom of Android Studio, you’ll find the Terminal tab. Click to open it. We will use the terminal to run a specific command that generates the SHA1 key.
Step 3: Run the Signing Report Command
Now type the following command in the terminal:
./gradlew signingReport
💡 Note: If you are on Windows, use this version instead:
gradlew signingReport
Then press Enter.
Step 4: Wait for the Build to Complete
After running the command, Gradle will begin building the project. Once complete, look at the output log. You’ll find the SHA1 key listed under the Variant section, typically in this format:
Variant: debug
SHA1: AB:CD:EF:12:34:56:78:90:AB:CD:EF:12:34:56:78:90:AB:CD:EF:12
Copy this key and keep it safe. You’ll use this in places like Firebase Console or Google Cloud Console for enabling services.
Common Problems and Their Solutions
Here are a few common issues developers encounter and how to resolve them:
❌ Command Not Found
If running the command gives you a “command not found” error, double-check:
- You’re in the correct project directory.
- You’ve used the right syntax based on your OS (
./gradlewfor macOS/Linux,gradlewfor Windows).
❌ SHA1 Key Not Showing
If the SHA1 key doesn’t show:
- Make sure your project is synced with Gradle.
- Clean the project (
Build > Clean Project) and then try again.
When Do You Need the SHA1 Key?
You typically need the SHA1 key when:
- Integrating Firebase Authentication
- Setting up Google Sign-In
- Using Firebase Cloud Messaging (FCM)
- Any API that uses OAuth2 or verifies app integrity
If your app doesn’t include these features, the SHA1 may not be required.
