# This script builds an android native-activity from go sourcecode and packages it as an apk.
|
|
|
|
# Android Studio does not need to be installed to run this script. The only prerequisite are the android-sdk
|
|
# command line tools (available as archive at https://developer.android.com/studio/index.html, see bottom of page).
|
|
# This script assumes that the command line tools are located in $HOME/android-sdk. If you wish to use
|
|
# another location set the $ANDROID_HOME environment variable accordingly. If the android-skd is already installed,
|
|
# you will likely want to call this script like this: "ANDROID_HOME=path/to/sdk path/to/this/script/build-android.sh".
|
|
|
|
# This script should be called from the folder containing the go source code, which in turn is expected to contain a folder called
|
|
# "android" with gradle files and the manifest. The native toolchain, go shared libray, assets and final apks will be copied into
|
|
# or created in this folder and it's subfolders. See the examples at (https://github.com/xlab/android-go/tree/master/examples) for
|
|
# example of the expected layout and content of the "android" folder
|

# Set default values if they are not provided by the environment.
