 Android requires that apps that you want to install are digitally signed. Unlike iOS where all certificates are issued by Apple, Android allows self signed apps so you can freely create certificates and keys required to sign apps.
 
-The process of creating certificates and keys may seem complicated but as long as you are in development, Defold fully automates the process. When you create an Android application bundle from the editor you can provide a specific certificate and key. If you don't, Defold generates a random certificate and a key and signs the resulting *.apk* (Android Application Package) file.

-It is important to note that when it is time to release an app on Google Play, you will need to create a certificate and key that you use to sign the app. The reason is that when you intend to publish an updated version of the app, _the updated *.apk* file needs to be signed with the same signature as the current version_. If you sign with a different private key, Google Play will reject the *.apk* update and you will need to publish the game as a totally new app.

 ## Creating an Android application bundle
 
-The editor lets you easily create a stand alone application bundle for your game. Before bundling you can specify what icon(s) to use for the app, set version code etc in the "game.project" [project settings file](/manuals/project-settings/#android). To bundle select <kbd>Project ▸ Bundle... ▸ Android Application...</kbd> from the menu.

 ## Permissions
 
 The Defold engine requires a number of different permissions for all engine features to work. The permissions are defined in the `AndroidManifest.xml`, specified in the "game.project" [project settings file](/manuals/project-settings/#android). You can read more about Android permissions in [the official docs](https://developer.android.com/guide/topics/permissions/overview). The following permissions are requested in the default manifest:
