Creating a release

You need to bump the version number in:

• src/Config.js - appVersion
• android/app/build.gradle - versionCode and versionName
• package.json - version - Not strictly required
• Update user agent in android/app/src/main/java/com/xkr/MainApplication.java and android/app/src/main/java/com/xkr/TurtleCoinModule.java

Then cd android ./gradlew bundleRelease Optionally ./gradlew installRelease

or yarn deploy-android

Integrating QR Codes or URIs

Kryptokrona Mobile Wallet supports two kinds of QR codes.

• Standard addresses / integrated addresses - This is simply the address encoded as a QR code.

• xkr:// URI encoded as a QR code.

Your uri must begin with xkr:// followed by the address to send to, for example, xkr://SEKReTyRMJx2LTUrbf2r7GdMJ9PY5yHbYN6MCZkKUVvKZSwwwf3HnUS6Jia3TkD4jWgfxeh1AEYV3DKEAesSb7mSAvNqfCNBXrg

There are a few optional parameters.

• name - This is used to add you to the users address book, and identify you on the 'Confirm' screen. A name can contain spaces, and should be URI encoded.
• amount - This is the amount to send you. This should be specified in atomic units.
• paymentid - If not using integrated address, you can specify a payment ID. Specifying an integrated address and a payment ID is illegal.

An example of a URI containing all of the above parameters:

xkr://SEKReTyRMJx2LTUrbf2r7GdMJ9PY5yHbYN6MCZkKUVvKZSwwwf3HnUS6Jia3TkD4jWgfxeh1AEYV3DKEAesSb7mSAvNqfCNBXrg?amount=10000&name=Starbucks%20Coffee&paymentid=f13adc8ac78eb22ffcee3f82e0e9ffb251dc7dc0600ef599087a89b623ca1402

This would send 100 XKR (10000 in atomic units) to the address SEKR2Fyavy8CXG8BPEbNeCHFZ1fuDCYCZ3vW5H5LXN4K2M2MHUpTENip9bbavpHvvPwb4NDkBWrNgURAd5DB38FHXWZyoBh4wW, using the name Starbucks Coffee (Note the URI encoding), and using a payment ID of f13adc8ac78eb22ffcee3f82e0e9ffb251dc7dc0600ef599087a89b623ca1402

You can also just display the URI as a hyperlink. If a user clicks the link, it will open the app, and jump to the confirm screen, just as a QR code would function. (Provided all the fields are given)
