Building the Hellocharge Sample App

The hellocharge app is available in the sample-hellocharge folder.

Check out this repo:

git clone https://github.com/square/point-of-sale-android-sdk.git
cd point-of-sale-android-sdk

Create a hellocharge.properties file in the sample-hellocharge folder, with a clientId key set to your application's client id which is the same as your application id in the Square Developer Portal (sq0idp-XXXXXXXXXXXXXXX). Do NOT use a sandbox clientId, as those do not work for the Point of Sale API.

echo clientId=\"[put your clientId here]\" > sample-hellocharge/hellocharge.properties

Build the SDK and the sample app:

./gradlew build

Add the SHA1 fingerprint of the sample app to your application dashboard:

keytool -list -printcert -jarfile ./sample-hellocharge/build/outputs/apk/sample-hellocharge-debug.apk

Install the sample app:

./gradlew :sample-hellocharge:installDebug
