1. Download the examples

git clone


2. Download the aar library and put it to the 'export' folder





cp wcs-android-sdk- export


3. Open the 'export' folder and execute the script that will prepare configs for further building. The result is placed into the 'output' folder.


cd export

./ wcs-android-sdk-


4. Edit the file and specify paths to Android SDK and NDK







Building examples with Gradle


Prepare examples for building, then go to the 'output' folder and start building:


cd output

gradle build


Building examples in Android Studio


Prepare examples for building and put them to the 'output' folder, then rename it to 'wcs_android_sdk_samples', for instance.


1. Install the following programs:

- Android Studio и Android SDK

- Android NDK


2. Open the project from the 'output' folder in Android Studio




4. Add Gradle run configuration to the Run / Debug Configurations menu
