Gradle templates

Learn what Gradle templates are and how to use them to gain more control over the build process.

Gradle templates configure how to build an Android application using Gradle. Each Gradle template represents a single Gradle project. Gradle projects can include, and depend on, other Gradle projects.

Gradle template files

A Gradle template consists of the following files:

File

Location

Contains

baseProjectTemplate.gradle
In the exported project, 
root/build.gradle
folder		Configuration information that affects all modules in the final Gradle project. It specifies which Android Gradle Plugin version to use and locations of java plugins. The locations are a combination of online repositories and java plugins inside of this project.
launcherTemplate.gradle
In the exported project, 
root/launcher/build.gradle
folder		Instructions on how to build the Android application. This includes bundling, signing, and whether to split the apk. It depends on the unityLibrary project and outputs either an .apk file or an app bundle.
mainTemplate.gradle
In the exported project, 
root/unityLibrary/build.gradle
folder		Instructions on how to build Unity as a Library. This outputs an .aar file. You can override the Unity template with a custom template in the Unity Editor. Refer to the Providing a custom Gradle build template section on this page for more details.
libTemplate.gradle
VariesIf an Android Library plug-in doesn't include a 
build.gradle
file, Unity uses the 
libTemplate.gradle
file as a template to generate one. After Unity generates the 
build.gradle
file, or if one already exists in the plug-in's directory, Unity copies the plug-in into the Gradle project.
settingsTemplate.gradle
In the exported project, 
root/settings.gradle
file		Specifies the names of modules that the Gradle build system should include when it builds the project. You can override the Unity template with a custom template in the Unity Editor. Refer to the Providing a custom Gradle build template section on this page for more details.
gradleTemplate.properties
In the exported project, 
root/gradle.properties
file		Configures the Gradle build system and specifies properties such as the size of the Java virtual machine (JVM) heap
To have more control over the Gradle project files that Unity produces, you can override Unity's default Gradle template files. For information on how to do this, refer to Modify Gradle project files with Gradle template files.

Modifying the exported Gradle project using C#

To modify the Gradle project after Unity assembles it, create a class that inherits from IPostGenerateGradleAndroidProject and override the OnPostGenerateGradleAndroidProject function. This function receives the path to the unityLibrary module as a parameter and you can use it to reach the application’s manifest and resources through C# scripting.
