Please keep in mind that both 64 bit CPU and 64 bit OS are mandatory condition. If your system DOES NOT meet this condition, you have to change affected hardware or software or the whole system. It is strongly recommended to use SSD (Solid State Disk) instead of HDD (Hard Disk Drive) because it will take less time when you are building the APS installation apk file. Recommended is just recommended and it is not a mandatory. However, you may still use a HDD when you are building apk file but note that the building process can take a long time to complete, although once started, you can leave it running unattended.

Tento článek je rozdělený do dvou částí.

  • In the overview part there is an explanation on what steps are necessary to build the APK file.

  • In the step by step walkthrough part you will find the screenshots of a concrete installation. Because the versions of Android Studio - the software development environment which we will use to build the APK - will change very quickly this will be not identical to your installation but it should give you a good starting point. Android Studio also runs on Windows, Mac OS X and Linux and there might be small differences in some aspects between each platform. If you find that something important is wrong or missing, please inform the facebook group „AAPS users“ or in the Discord chat Android APS so that we can have a look at this.

Průvodce krok za krokem

Detailed description of the steps necessary to build the APK file.

Nainstalujte git (pokud ho ještě nemáte)

Follow the manual on the git installation page.

Instalace Android Studio

The following screenshots have been taken from Android Studio Version Arctic Fox | 2020.3.1. Screens can change in future versions of Android Studio. But you should be able to find your way through. Help from the community is provided.

One of the most important things when installing Android Studio: Be patient! During installation and setup Android Studio is downloading a lot of stuff which will take its time.

Download Android Studio from here and install it on your computer.

On first start you will find the setup wizard:

Select „Do not import settings“ as you have not used it before.

Do not import settings

Decide whether you want to share data with Google or not.

Share data with Google

On the following screen click „Next“.

Welcome screen

Select „Standard“ installation and click „Next“.

Standard installation

Select the theme for the user interface you like. (In this manual we used „Light“.) Then click „Next“.

Note: This is just the color scheme. You can select whatever you like (i.e. „Darcula“ for dark mode). This selection has no influence on building the APK but the following screenshots might look different.

UI color scheme

Click „Next“ on the „Verify Settings“ dialog.

Verify settings

Click on all three license agreement parts and select „Agree“. When you have agreed to all, the „Finish“ button will be enabled and you can „Finish“.

Signing means that you indicate your app to be your own creation but in a digital way as a kind of digital fingerprint within the app itself. That is necessary because Android has a rule that it only accepts signed code to run for security reasons. For more information on this topic, follow this link.

  • After Android Studio is started, wait until all background tasks are finished.
