This project builds GDAL into an Android Archive(AAR) file. So you can use GDAL's functionality in your Android App.
Version Info: GDAL 3.7.0, PROJ 9.2.1, SQLITE 3.42.0, EXPAT 2.5.0(used for kml support)
This project provides a Dockerfile which you can build a docker image which is suitable to build GDAL4Android without environment problems. Below is some examples about how you can build GDAL4Android with docker.
# Note: don't forgot to install docker.
cd <your-workspace-path>
git clone https://github.com/kikitte/GDAL4Android.git
cd GDAL4Android
# this step produces an image named gdal4android_builder_img
docker build -t gdal4android_builder_img - < docker/Dockerfile
# this step runs a container so you can build GDAL4Android within it.
docker run -it --name gdal4android_builder -v .:/root/GDAL4Android gdal4android_builder_img
# Note: You are now in the container environment, /root/GDAL4Android is the project root directory in the container.
# override the default FindJNI.cmake,
cp /root/GDAL4Android/docker/cmake_modules/FindJNI.cmake /usr/share/cmake-3.22/Modules/FindJNI.cmake
# change working direction to the project root direcory
cd /root/GDAL4Android
# clean project first
./gradlew gdal:clean
# build gdal aar, the output aar file is in: GDAL4Android/gdal/build/outputs/aar/gdal-release.aar
./gradlew gdal:assembleRelease
# build gdaltest apk, the output apk fiel is in: GDAL4Android/gdaltest/build/outputs/apk/debug/gdaltest-debug.apk
./gradlew gdaltest:assembleDebug-
Linux
bash
some utilities: getconf & make & cmake & libtool & ant & ...
swig: for building gdal java bindings.
-
Android Studio 2022.2 or newer
with latest ndk installed, r25c or newer
use Android Studio default JDK as Gradle JDK (specified in Gradle settings)
You may encounter problems caused by development environment, if something is missing, just install it.
How to build?
