Automatic Code Signing for Secured Android Apps on Appdome

Last updated January 3, 2024 by Appdome

Google requires Android Mobile apps to be signed before they can be installed on a mobile device. A valid signature ensures the integrity of an app and stands as proof that the app has not been tampered with. This Knowledge Base explains how to sign secured Android Apps without Android Studio.

We hope you find it useful and enjoy using Appdome!

As an Appdome user, you can sign any built app either by using Appdome’s built-in signing capabilities or using your own mechanism outside of Appdome. It’s your choice. If you wish to Deploy apps from Appdome, the process is quick and easy for any Android app, including Native Android, hybrid apps and non-native apps built in Maui, Xamarin, Cordova, React Native, Ionic and more.

Prerequisites for Signing Secured Android Apps Without Android Studio

In order to sign your Android app, you’ll need a valid signing certificate stored in the Android development environment.  To use your certificate, you’ll need access to the following.

  • Appdome account
  • Appdome built mobile app
  • Keystore – This should be the same keystore file used to sign your Android app when distributing it via Google Play.
  • Keystore Password – The password used to unlock your keystore.
  • Key Alias – The name you assigned to your keystore.
  • Key Password – This is the specific password defined for your signing key.

When you click Sign My App, Appdome will analyze the fused app’s components and calculate a checksum that represents the exact state of each component within the app. Embedding the checksum combined with your signing credentials into the app’s components will ensure that the app can’t be modified or tampered with once the signing is complete.
