Configuring Android Studio

To install the Android Studio IDE, follow the instructions from the official Android guide. For TomTom Digital Cockpit the recommended version is Android Studio version Chipmunk | 2021.2.1 or newer.

If you already have this Android Studio version installed, you can proceed to section Building with Android Studio.

When opening Android Studio for the first time, a dialog box Import Android Studio Settings may show. Select Do not import settings and click OK.

Gradle plugin for Android Studio

During this installation, or at any time after that, Android Studio may propose upgrading its Gradle plugin:

Ignore this upgrade! The TomTom Digital Cockpit build files specify the exact version of the plugin that is needed. The upgrade by Android Studio would change the TomTom Digital Cockpit build files into using a wrong and hard-coded version of this plugin.

Building with Android Studio

This section explains how to configure Android Studio for building the TomTom Digital Cockpit template app and the TomTom Digital Cockpit example apps.

Install Android 11 (R) SDK:

  • In the Welcome to Android Studio dialog, select More Actions > SDK Manager.
  • The Settings for new projects dialog appears. In tab SDK Platforms, verify whether Android 11.0 (R) is installed. If not yet installed, enable it and click Apply.

Now open the TomTom Digital Cockpit example app project:

  • In the Welcome to Android Studio dialog, select Open.
  • When this dialog does not show, you can open the project via File > Open.

  • From your local clone of the TomTom Digital Cockpit Example sources, select the top-level build.gradle.kts file, and click OK.

  • Android Studio may show a popup Trust Gradle Project?, on which you must click the Trust Project button.

Ensure that Android Studio uses OpenJDK11:

  • Go to File > Settings then open the tab Build, Execution, Deployment > Build Tools > Gradle.

    • Mac: Go to Android Studio > Preferences... then open the tab Build, Execution, Deployment > Build Tools > Gradle.
  • Under Gradle JDK select the OpenJDK version that you downloaded earlier (normally shown under JAVA_HOME) and click OK.

Gradle Sync should start running automatically, then Android Studio will configure the project and download its dependencies. If it does not, start it manually by clicking on the Gradle Sync icon. This step takes several minutes, depending on your internet connection and your PC's hardware configuration.

Now you can browse the source code in the IDE.

Build the application by clicking on the green hammer icon:

Note: Building the application may report an error like below. When this happens, open the SDK Manager via Tools > SDK Manager, then in tab SDK Tools tick Show Package Details and install the required package and/or accept its license terms.

License for package Android SDK Build-Tools 30.0.2 not accepted.
