How to specify output .apk file path when using fastlane gradle? - fastlane

Question

I have different product flavors of my app and I build them with fastlane. This is my fastfile:
default_platform(:android)
platform :android do
desc "Release apk with different urls"
lane :release do
gradle(
task: "assemble",
build_type: "release",
flavor: "flavorname",
print_command: true,
properties: {
"android.injected.signing.store.file" => "Key.jks",
"android.injected.signing.store.password" => "KeyPass",
"android.injected.signing.key.alias" => "KeyAlias",
"android.injected.signing.key.password" => "KeyPass"
}
)
end
end
The problem is apk files are created in project directory.
(projectname/app/build/outputs/apk/flavorname/release/app-flavorname-release.apk)
How to move this apk files to my Desktop automatically?

Answer 1

I use the following under my gradle call:
lane :release do
gradle(...)
APK_LOCATION = "#{lane_context[SharedValues::GRADLE_APK_OUTPUT_PATH]}"
sh("mv #{APK_LOCATION} ~/Desktop/")
end
The advantage of using the variable is that you will be able to use the same code for release and debug apk.
Cheers.

Answer 2

It doesn't seem that gradle has an option to specify the output.
What I suggest you is to add a command line just after the gradle is done to move this .apk to the Desktop or wherever you want.
sh "mv ../app/build/outputs/apk/release/app-release.apk path/to/Desktop"

You can also use fastlane action copy_artifacts instead of mv
lane :release do
gradle(...)
copy_artifacts(
artifacts: ['*/build/outputs/apk/**/*.apk'],
target_path: '~/Desktop/'
)
end
Wilcard */build/outputs/apk/**/*.apk will work with any build types, flavors app module name.
Or as said #janpio above, you can use variable GRADLE_APK_OUTPUT_PATH:
lane :release do
gradle(...)
copy_artifacts(
artifacts: [lane_context[SharedValues::GRADLE_APK_OUTPUT_PATH]],
target_path: '~/Desktop/'
)
end
