Kompilieren für Android


In most cases, using the built-in deployer and export templates is good enough. Compiling the Android APK manually is mostly useful for custom builds or custom packages for the deployer.

Also, you still need to follow the steps mentioned in the Exportieren für Android tutorial before attempting to build a custom export template.


Zum Kompilieren unter Windows, Linux oder MacOS ist Folgendes erforderlich:

  • Python 3.5+.
  • SCons 3.0+ build system.
  • Android SDK (Kommandozeilen-Tools reichen aus).
    • Erforderliche SDK-Komponenten werden von Gradle automatisch installiert (mit Ausnahme des NDK).
  • Android NDK r17 oder höher.
  • Gradle (wird bei Fehlen automatisch heruntergeladen und installiert).
  • JDK 8 (entweder OpenJDK oder Oracle JDK).
    • JDK 9 oder höher wird derzeit nicht unterstützt.
    • Sie können einen Build herunterladen von ojdkbuild.

Buildsystem einrichten

Set the environment variable ANDROID_HOME to point to the Android SDK. If you downloaded the Android command-line tools, this would be the folder where you extracted the contents of the ZIP archive. Later on, gradlew will install necessary SDK components in this folder. However, you need to accept the SDK component licenses before they can be downloaded by Gradle. This can be done by running the following command from the root of the SDK directory, then answering all the prompts with y:

tools/bin/sdkmanager --licenses

Set the environment variable ANDROID_NDK_ROOT to point to the Android NDK. You also might need to set the variable ANDROID_NDK_HOME to the same path, especially if you are using custom Android modules, since some Gradle plugins rely on the NDK and use this variable to determine its location.

To set those environment variables on Windows, press Windows + R, type "control system", then click on Advanced system settings in the left pane, then click on Environment variables on the window that appears.

To set those environment variables on Linux or macOS, use export ANDROID_HOME=/path/to/android-sdk and export ANDROID_NDK_ROOT=/path/to/android-ndk where /path/to/android-sdk and /path/to/android-ndk point to the root of the SDK and NDK directories.

Erstellen der Exportvorlagen

Godot needs two export templates for Android: the optimized "release" template (android_release.apk) and the debug template (android_debug.apk). As Google will require all APKs to include ARMv8 (64-bit) libraries starting from August 2019, the commands below will build an APK containing both ARMv7 and ARMv8 libraries.

Compiling the standard export templates is done by calling SCons from the Godot root directory with the following arguments:

  • Release-Vorlage (wird beim Exportieren verwendet, wenn das Kontrollkästchen Debugging aktiviert deaktiviert ist)
scons platform=android target=release android_arch=armv7
scons platform=android target=release android_arch=arm64v8
cd platform/android/java
# On Windows
.\gradlew generateGodotTemplates
# On Linux and macOS
./gradlew generateGodotTemplates

Die resultierende APK befindet sich unter bin/android_release.apk.

  • Debug-Vorlage (wird beim Exportieren verwendet, wobei Debugging aktiviert aktiviert ist)
scons platform=android target=release_debug android_arch=armv7
scons platform=android target=release_debug android_arch=arm64v8
cd platform/android/java
# On Windows
.\gradlew generateGodotTemplates
# On Linux and macOS
./gradlew generateGodotTemplates

Die resultierende APK wird sich unter bin/android_debug.apk befinden.

Unterstützung für x86-Geräte hinzufügen

If you also want to include support for x86 and x86-64 devices, run the SCons command a third and fourth time with the android_arch=x86, and android_arch=x86_64 arguments before building the APK with Gradle. For example, for the release template:

scons platform=android target=release android_arch=armv7
scons platform=android target=release android_arch=arm64v8
scons platform=android target=release android_arch=x86
scons platform=android target=release android_arch=x86_64
cd platform/android/java
# On Windows
.\gradlew generateGodotTemplates
# On Linux and macOS
./gradlew generateGodotTemplates

This will create a fat binary that works on all platforms. The final APK size of exported projects will depend on the platforms you choose to support when exporting; in other words, unused platforms will be removed from the APK.

Bereinigen der generierten Exportvorlagen

Mit den folgenden Befehlen können Sie die generierten Exportvorlagen entfernen:

cd platform/android/java
# On Windows
.\gradlew cleanGodotTemplates
# On Linux and macOS
./gradlew cleanGodotTemplates

Verwenden der Exportvorlagen

Godot needs release and debug APKs that were compiled against the same version/commit as the editor. If you are using official binaries for the editor, make sure to install the matching export templates, or build your own from the same version.

When exporting your game, Godot opens the APK, changes a few things inside and adds your files.

Vorlagen installieren

The newly-compiled templates (android_debug.apk and android_release.apk) must be copied to Godot's templates folder with their respective names. The templates folder can be located in:

  • Windows: %APPDATA%\Godot\templates\<version>\
  • Linux: $HOME/.local/share/godot/templates/<version>/
  • MacOS: $HOME/Library/Application Support/Godot/templates/<version>/

<version> is of the form major.minor[.patch].status using values from version.py in your Godot source repository (e.g. 3.0.5.stable or 3.1.dev). You also need to write this same version string to a version.txt file located next to your export templates.

However, if you are writing your custom modules or custom C++ code, you might instead want to configure your APKs as custom export templates here:


You don't even need to copy them, you can just reference the resulting file in the bin\ directory of your Godot source folder, so that the next time you build you will automatically have the custom templates referenced.


Die Plattform wird in SCons nicht angezeigt

Double-check that you've set both the ANDROID_HOME and ANDROID_NDK_ROOT environment variables. This is required for the platform to appear in SCons' list of detected platforms. See Setting up the buildsystem for more information.

Anwendung nicht installiert

Android könnte sich beschweren, dass die Anwendung nicht korrekt installiert ist. Wenn dies der Fall ist:

  • Prüfen Sie, ob der Debug-Schlüsselspeicher ordnungsgemäß generiert wurde.
  • Überprüfen Sie, ob die ausführbare Datei jarsigner aus JDK 8 stammt.

Wenn es immer noch fehlschlägt, öffnen Sie eine Befehlszeile und führen Sie logcat aus:

adb logcat

Then check the output while the application is installed; the error message should be presented there. Seek assistance if you can't figure it out.

Die Anwendung wird sofort beendet

If the application runs but exits immediately, this might be due to one of the following reasons:

  • Make sure to use export templates that match your editor version; if you use a new Godot version, you have to update the templates too.
  • libgodot_android.so ist nicht in libs/<android_arch>/, wo <android_arch> die Architektur des Geräts ist.
  • The device's architecture does not match the exported one(s). Make sure your templates were built for that device's architecture, and that the export settings included support for that architecture.

In jedem Fall sollte adb logcat auch die Fehlerursache anzeigen.
