This document describes how to sign your APK or app bundle using Android Studio, including creating and storing your certificate, signing different build configurations using different certificates, and configuring the build process to sign your APKs automatically.

The owner of the certificate holds the corresponding private key. When you sign an APK, the signing tool attaches the public-key certificate to the APK—the same is true when signing an app bundle. This helps Android ensure that any future updates to your app are authentic and come from the original author. The key used to create this certificate is called the app signing key.

A keystore is a binary file that contains one or more private keys. Every app must use the same certificate throughout its lifespan in order for users to be able to install new versions as updates to the app. For more about the benefits of using the same certificate for all your apps throughout their lifespans, see below. Sign your debug build When running or debugging your project from the IDE, Android Studio automatically signs your app with a debug certificate generated by the Android SDK tools.

Because the debug certificate is created by the build tools and is insecure by design, most app stores including the Google Play Store will not accept an APK or app bundle that's signed with a debug certificate for publishing. Android Studio automatically stores your debug signing information in a signing configuration so you do not have to enter it every time you debug. 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. For more information about how to build and run apps for debugging, see. Expiry of the debug certificate The self-signed certificate used to sign your app for debugging has an expiration date of 365 days from its creation date.

When the certificate expires, you will get a build error. To fix this problem, simply delete the debug. Note that you must run your app, building alone does not regenerate the keystore and debug key. Manage your key Because your app signing key is used to verify your identity as a developer and to ensure seamless and secure updates for your users, managing your key and keeping it secure are very important, both for you and for your users. You can choose either to opt in to use App Signing by Google Play to securely manage and store your app signing key using Google's infrastructure or to manage and secure your own keystore and app signing key.

Loss of the app signing key means that an app cannot be updated, so it is critical for it not to be lost. Compromise of the key would allow a malicious attacker to deploy a malicious version of your app as an update over an existing install.

With Play App Signing, developers only manage an upload key which can be reset in the case of loss and compromise. In the event of compromise, an attacker also needs access to the developer account to be able to do anything malicious.

Use App Signing by Google Play With App Signing by Google Play, Google manages and protects your app's signing key for you and uses it to sign your APKs for distribution.

And, because app bundles defer building and signing APKs to the Google Play Store, you need to enroll in App Signing by Google Play before you upload your app bundle. When using App Signing by Google Play, you will use two keys: the app signing key and the upload key.

You keep the upload key and use it to sign your app for upload to the Google Play Store. When you opt in to use App Signing by Google Play, you export and encrypt your app signing key using the Play Encrypt Private Key tool provided by Google Play, and then upload it to Google's infrastructure.

Then you create a separate upload key and register it with Google. When you are ready to publish, you sign your app using the upload key and upload it to Google Play. Google then uses the upload certificate to verify your identity, and signs your APK s with your app signing key for distribution as shown in figure 1. If you do not already have an app signing key, you can generate one during the sign-up process.

Signing an app with App Signing by Google Play When you use App Signing by Google Play, if you lose your upload key, or if it is compromised, you can contact Google to revoke your old upload key and generate a new one. Because your app signing key is secured by Google, you can continue to upload new versions of your app as updates to the original app, even if you change upload keys.

For more information about how to opt in to use App Signing by Google Play, see. Manage your own key and keystore Instead of using App Signing by Google Play, you can choose to manage your own app signing key and keystore.

If you choose to manage your own app signing key and keystore, you are responsible for securing the key and the keystore. Additionally, you cannot upload Android App Bundles without enrolling in App Signing by Google Play. When you are ready to create your own key and keystore, make sure you first choose a strong password for your keystore and a separate strong password for each private key stored in the keystore.

You must keep your keystore in a safe and secure place. If you lose access to your app signing key or your key is compromised, Google cannot retrieve the app signing key for you, and you will not be able to release new versions of your app to users as updates to the original app. For more information, see , below. If you manage your own app signing key and keystore, when you sign your APK, you will sign it locally using your app signing key and upload the signed APK directly to the Google Play Store for distribution as shown in figure 2.

Create a new keystore in Android Studio. This should be different from the password you chose for your keystore. Your key should be valid for at least 25 years, so you can sign app updates with the same key through the lifespan of your app.

This information is not displayed in your app, but is included in your certificate as part of the APK. Once you complete the form, click OK. Otherwise, first and then return to complete this step. Note: If you are using App Signing by Google Play, you should specify your upload key here. If you are managing your own app signing key and keystore instead, you should specify your app signing key. For more information, see above. Select a private key in Android Studio.

To be able to upload your app bundle and take advantage of , you need to upload this encrypted file to the Play Console and enroll in.

If you selected the option to export your signing key, you can quickly navigate to it by clicking the dropdown arrow in the bottom right corner of the popup to expand it and clicking Show Exported Key File, as shown in figure 6. After the IDE finishes generating your signed app bundle, click the links in the popup to analyze or locate your app bundle, or locate your exported signing key.

You may now distribute your signed app through an app marketplace like the Google Play Store, or using the mechanism of your choice. For more about how to publish your signed APK to the Google Play Store, see. To learn more about other distribution options, read.

Sign Wear OS apps If you are building an Wear OS app, the process for signing the app can differ from the process described on this page.

See the information about. Signing considerations You should sign your app with the same certificate throughout its expected lifespan. The system allows the update if the certificates match. If you sign the new version with a different certificate, you must assign a different package name to the app—in this case, the user installs the new version as a completely new app. In this way you can deploy your app in modules, and users can update each of the modules independently. By signing multiple APKs with the same certificate and using signature-based permissions checks, your apps can share code and data in a secure manner.

If you plan to support upgrades for an app, ensure that your app signing key has a validity period that exceeds the expected lifespan of that app. A validity period of 25 years or more is recommended.

When your key's validity period expires, users will no longer be able to seamlessly upgrade to new versions of your app. If you plan to publish your apps on Google Play, the key you use to sign your app must have a validity period ending after 22 October 2033. Google Play enforces this requirement to ensure that users can seamlessly upgrade apps when new versions are available.

If you use , Google ensures your apps are correctly signed and able to receive updates throughout their lifespans. Secure your key If you choose to manage and secure your app signing key and keystore yourself instead of opting in to , securing your app signing key is of critical importance, both to you and to the user.

If you allow someone to use your key, or if you leave your keystore and passwords in an unsecured location such that a third-party could find and use them, your authoring identity and the trust of the user are compromised. Note: If you use App Signing by Google Play, your app signing key is kept secure using Google's infrastructure.

You should still keep your upload key secure as described below. If your upload key is compromised, you can contact Google to revoke it and receive a new upload key. If a third party should manage to take your key without your knowledge or permission, that person could sign and distribute apps that maliciously replace your authentic apps or corrupt them. Such a person could also sign and distribute apps under your identity that attack other apps or the system itself, or corrupt or steal user data.

Your private key is required for signing all future versions of your app. If you lose or misplace your key, you will not be able to publish updates to your existing app. You cannot regenerate a previously generated key.

Your reputation as a developer entity depends on your securing your app signing key properly, at all times, until the key is expired. In general, if you follow common-sense precautions when generating, using, and storing your key, it will remain secure.

Remove signing information from your build files When you create a signing configuration, Android Studio adds your signing information in plain text to the module's build. If you are working with a team or open-sourcing your code, you should move this sensitive information out of the build files so it is not easily accessible to others. These instructions assume you have configured a single signing configuration for your release build type, as described in , above.

} Note: You could choose to store your keystore. In that case, you should modify the code above to correctly initialize keystorePropertiesFile using your actual keystore. Modify the signingConfigs block of your module's build. Because your build files no longer contain sensitive information, you can now include them in source control or upload them to a shared codebase. Be sure to keep the keystore.

This may include removing it from your source control system. Sign your app from command line You do not need Android Studio to sign your app. You can sign your app from the command line, using apksigner for APKs or jarsigner for app bundles, or configure Gradle to sign it for you during the build. Either way, you need to first generate a private key using. For example: keytool -genkey -v -keystore my-release-key.

This example prompts you for passwords for the keystore and key, and to provide the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key. The keystore contains a single key that is valid for 10,000 days.

Now you can , or. Sign your app manually from the command line If you haven't already done so,. If you want to sign an app bundle from the command line, you can use. If you instead want to sign an APK, you need to use zipalign and apksigner as described below.

The apksigner tool supports other signing options, including signing an APK file using separate private key and certificate files, and signing an APK using multiple signers. For more details, see the reference. Note: To use the apksigner tool, you must have revision 24.

You can update this package using the. For example: android {... } } } Note: In this case, the keystore and key password are visible directly in the build. For improved security, you should.

Now, when you by invoking a Gradle task, Gradle signs your app and runs zipalign for you. So you can build, align, sign, and install the release APK on an emulator or device all with the installRelease task. An app signed with your private key is ready for distribution, but you should first read more about how to and review the.
