wingu-android-sdk is an SDK for service. This framework will allow you to find nearby beacons and geofences at user's location, and display content attached to those channels. It also supports discovering content via QR codes and NFC tags.

1. Installation

In build.gradle of your application module add this:

android {
  compileSdkVersion 27

  defaultConfig {
    // wingu SDK requires `minSdkVersion >= 21` and `targetSdkVersion <= 27`.
    minSdkVersion 21
    targetSdkVersion 27
    multiDexEnabled true

repositories {
  maven { url "" }
  maven { url "" }
  maven { url "" }

dependencies {
  implementation 'com.github.Speicher210.wingu-android-sdk:sdk:3.6.0'
  implementation 'com.github.Speicher210.wingu-android-sdk:component-video:3.6.0' // optional
  implementation 'com.github.Speicher210.wingu-android-sdk:qrcodescanner:3.6.0' // optional

If you are using Kotlin standard library, Support Libraries, Google Play Services or have issues with dependencies, read dependency management.

Initialize wingu SDK in your Application subclass:

override fun onCreate() {
    WinguSDKBuilder.with(this, YOUR_WINGU_API_KEY)
//      .registerComponent(..) // optionally activate maps & video components

For start, you can use WinguSDKBuilder.DEMO_APP_ID key.

2. Requirements

To be able to listen for nearby channels (iBeacons and geofences) you need to have:

  • runtime LOCATION permission (on Android 6+; either ACCESS_COARSE_LOCATION or ACCESS_FINE_LOCATION)
  • Bluetooth on
  • location services on
  • Google Play services

You can check this on your own, or use a PrerequisitesChecker class, for example in your main activity:


override fun onStart() {
    if (PrerequisitesChecker.checkWithDefaultDialogs(this, WINGU_SDK_PREREQUISITES_REQUEST)) {
        // all prerequisites are met
    // if `checkWithDefaultDialogs` above returned `false`,
    // dialogs are shown to resolve any issues,
    // and results are returned in `onActivityResult`

override fun onStop() {

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
        val results = PrerequisitesChecker.getResolveResults(data)
        if (results != null && results.failed.isEmpty()) {
        } else {
            Log.e("wingu", "Could not get ResolveResults or some failed")

3. Listening for nearby channels

Once you have all the prerequisites, you can listen for nearby channel events. Using NearbyChannelObserver you can be notified for example when you enter a geofence zone, or go out of beacon range.

private var channelsSubscription: Subscription? = null

private fun listenForNearbyChannels() {
    channelsSubscription = WinguSDK.getInstance()
            { channelEvents -> Log.d("wingu", "$channelEvents") },
            { throwable -> Log.e("wingu", "Could not get nearby channels", throwable) }

private fun stopListeningForNearbyChannels() {
    channelsSubscription = null

Alternatively, you can fetch all channels that are nearby at any given moment:

val nearbyChannels = WinguSDK.getInstance().getNearbyChannelObserver().getCurrentNearbyChannels()

Finally, you can display content of selected channel:

private fun onChannelClicked(channel: Channel) {
    val intent = ChannelDetailsActivity.newInstance(this, channel,

If you used WinguSDKBuilder.DEMO_APP_ID in the first step, you can launch the Android Emulator and set latitude to 37.422 and longitude to -122.084. Within a few seconds you will receive your first channel event. If you change the location (for example set the latitude to 38.422) you will receive a LOST event, and the content will no longer be accessible. Note: due to limitations in the Emulator, it's not possible to receive iBeacon or geofence events when the app is in background.
