Plugin wrapper for the Polar SDK

Getting Started

Android

app/build.gradle:

android {
  buildTypes {
    release {
      minifyEnabled false
      shrinkResources false
    }
  }
}

dependencies {
    implementation 'polarofficial:polar-ble-sdk:3.2.4@aar'
}

If you can figure out how to get it to work in release mode without disabling minify please make a pull request.
