Overview

To use the Google Fit for Android, you need an OAuth 2.0 client ID forAndroid applications.

How to create an Android Keystore file The following tutorial guides you through the steps to generate a keystore file required to build an Android app for submission to the Google Play Store. We will be using the software KeyStore Explorer to generate the keystore file and Headjack to build the Cardboard VR Play Store App. Keytool will quickly generate a public/private key pair and store them in a keystore for you after you answer a few simple questions. Keytool has a number of commands. The most common command used for signing Android builds -genkeypair, commonly abbreviated -genkey. A signing configuration is an object consisting of all of the necessary information to sign your app, including the keystore location, keystore password, key name, and key password. You cannot directly edit the debug signing configuration, but you can configure how you sign your release build. I am looking for the best way to protect sensitive data in Android devices, e.g. Secret or private keys, and found Android Keystore System.Based on the documentation, key material may be bound to secure hardware (e.g., Trusted Execution Environment (TEE), Secure Element (SE)) of Android device. It implies that not all of the Android devices support this. . Key file structure highlights user -level KeyChain isolation. /data/misc/keystore/userX, as before (where X is the Android user ID, starting with 0 for the primary user). Encryption of key files depends on Android version and TEE availability. If keystore not hardware backed, lockscreen password used to derive keys for protecting.

All Android apps are signed with a digital certificate for which you hold theprivate key. Refer to the Android guide to signing your applicationsfor more information about digital certificates.

Android OAuth client IDs are linked to specific certificate/package pairs. Youonly need one ID for each certificate, no matter how many users you have forthe app.

Getting an ID for your app requires several steps. These steps are outlinedbelow.

  1. Find your app's certificate information.
  2. Create or modify a project in the Google API Console.
  3. Request an OAuth 2.0 client ID.

Find your app's certificate information

The API key is based on a short form of your app's digital certificate, known as its SHA-1 fingerprint. To display the SHA-1 fingerprint for your certificate, first ensure that you are using the right certificate. You may have two certificates:

  • A debug certificate: The Android SDK tools generate this certificate automatically when you do a debug build. Only use this certificate with apps that you're testing. Do not attempt to publish an app that's signed with a debug certificate. The debug certificate is described in more detail in Signing in Debug Mode in the Android Developer Documentation.
  • A release certificate: The Android SDK tools generate this certificate when you do a release build. You can also generate this certificate using the keytool program. Use this certificate when you are ready to release your app to the world.

Follow the steps below to display a certificate's SHA-1 fingerprint using the keytool program with the -v parameter. For more information about Keytool, see the Oracle documentation.

Displaying the debug certificate fingerprint

  1. Locate your debug keystore file. The file name is debug.keystore, and is created the first time you build your project. By default, it is stored in the same directory as your Android Virtual Device (AVD) files:

    • macOS and Linux: ~/.android/
    • Windows Vista and Windows 7: C:Usersyour_user_name.android

  2. List the SHA-1 fingerprint:

    • For Linux or macOS, open a terminal window and enter the following:

    • For Windows Vista and Windows 7, run:
