how to get sha 1 in android studio with code examples

In this article, we will be discussing how to get SHA-1 in Android Studio with code examples. SHA-1 is a cryptographic hash function that generates a fixed-length output (160 bits), which is commonly used for checking the authenticity of digital data, such as data transmission security, message integrity, and file validation. In Android apps, SHA-1 fingerprints are required when you integrate your app with Google services, such as Google Maps, Firebase, and Google Sign-In. In this tutorial, we will delve into the steps required to get SHA-1 in Android Studio.

Step 1: Create a new project or open an existing one in Android Studio

To get started, the first thing you need to do is create a new project in Android Studio if you haven't already done so. If you already have an existing project, you can open it in Android Studio. If you choose to create a new project, you can follow the steps outlined by the wizard until your project is fully set up.

Step 2: Open the terminal window

Next, you should open the terminal window in Android Studio. The terminal window in Android Studio is used to execute gradle build commands, including issuing the SHA-1 command.

To open the terminal window in Android Studio:

Click on the "Terminal" tab located at the bottom of the screen.

Step 3: Move to the project folder

Once you have opened the terminal window, the next step is to navigate to the project folder in the terminal window. You can either type in the required commands in the terminal window or click ‘Terminal’ at the top of the screen then select ‘New Terminal’.

Step 4: Execute the SHA-1 command

After navigating to the project folder, the next step is to execute the SHA-1 command within the terminal window to get the SHA-1. This command in Android Studio is called the keytool command, and it generates a hash value from your app’s default keystore file.

You use the following command in your terminal window:

On Windows:
keytool -list -v -keystore "%USERPROFILE%.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

On Linux or Mac:
keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android

After running the command, you should see a long string of characters that represents the SHA-1 fingerprint of your application. Copy this entire string for future use.

Step 5: Add the SHA-1 to your Google Project

After obtaining the SHA-1 fingerprint for your app, the next step is to add it to your Google project. This is a simple process, you have to navigate to the Google API Console and select or create a project, then select the Credentials option.

Once you are on the Credentials page, click on the "Create Credentials" button and select "OAuth client ID." From there, follow the prompts to create the client ID, including adding the SHA-1 key you just created in Android Studio.

Conclusion

In conclusion, getting SHA-1 in Android Studio is an essential part of incorporating Google services into your Android app. Using the keytool command within the terminal window of Android Studio is the most efficient way of getting SHA-1. With the above steps, you should be able to seamlessly integrate your application with Google services.

here are some additional details about the various topics discussed in the article:

Creating a new project in Android Studio:

When creating a new project in Android Studio, you will be prompted to choose a project type such as Empty Activity, Basic Activity, Tabbed Activity, and more. You will also need to select a name for your project, a package name (which should be unique), and a location to save the project files on your computer. Once you have selected the options, click on the ‘Finish’ button to create the project.

Opening an existing project in Android Studio:

If you have an existing project, you can open it in Android Studio by clicking on ‘File’ > ‘Open’ and navigating to the location of the project folder on your computer. Once you have selected the project folder, click on ‘OK’ to open the project in Android Studio.

Terminal window in Android Studio:

The terminal window in Android Studio is a command-line interface that allows you to execute a variety of gradle tasks and commands such as generating SHA-1. You can access the terminal window by clicking on the ‘Terminal’ tab located at the bottom of the screen.

Using keytool to generate SHA-1:

Keytool is a command-line utility in Java that is used to manage certificates in a keystore. To generate SHA-1 for your Android app, you will need to use the keytool command. The command varies slightly depending on whether you are using Windows, Linux, or Mac. When executing the command, make sure to replace ‘androiddebugkey’ with the application package name.

Adding the SHA-1 to your Google project:

To add the SHA-1 fingerprint to your Google Project, you will need to navigate to the Google API Console, select or create a project, and then go to the ‘Credentials’ section. Here, you can create a new client ID if required, and then add the SHA-1 key you generated in Android Studio.

In conclusion, getting the SHA-1 fingerprint is a crucial part of integrating your Android application with Google Services such as Google Maps, Firebase, and Google Sign-In. By following the steps outlined in this article, you should be able to generate the SHA-1 key with ease. Remember to keep the key safe and secure as it contains sensitive information about your application.
