This will get your Android app Kin enabled in a few minutes. All you need to do is add a simple class file to your app, and you should be able to make calls to Kin's blockchain immediately.
Make sure you have read Getting Started and have the required environment variables
- Add the Kin.kt class to your app
- Add entries in AndroidManifest.xml to your app's manifest
- Add entries in build.gradle to your app's gradle
- Make sure
app_icon.pngexists in your
- Import and instantiate the class in any
- Instantiation requires several variables from the getting started section:
val kin = Kin( applicationContext, //Application context false, //In Production mode 165, //Your App Index "GC6D...32XS", //Your Public Address "MyUser", //Your device's current user "MyPassword", //Device's current password ::balanceChanged, //get notifications for balance changes ::paymentHappened //get notifications for payments )
- See MainActivity.kt for instantiation and sample calls
Any transactions made by the device will alert your server with a webhook. (see server tutorials). Your server will receive a notification of the transaction, including
MyPassword credentials above. The credentials help your server track transactions from specific users.
However, you can safely test your device code without turning on your webhooks.
A demo App is included that you can run and test. To use the app:
- Pull https://github.com/kintegrate/kin-starter-kotlin into a local folder
- Access the
/demofolder on your local.
- Open in android studio and click run to emulate it. The app runs on Kin's test network and will display its Kin blockchain address on startup, which will have 0 Kin.
To fund the demo app or any address in Kin's
TEST blockchain, simply copy its address and paste it to Kin drops:
The service will send it 10 Kin in the test network. You can refresh this as often as you like to add more Kin to your app.
