Augmented Reality

Do you ever wanted to play with AR a little but didn't want to dive deep into whole ARCore experience?
In our company as a part of R&D research we developed a little library that provides you with a view showing labels of the destinations provided by you. It's an open source project so you can contribute or write suggestions of new features at our repo https://github.com/netguru/ar-localizer-view-android

You can easily use it in your projects:

Using library

Add repository in you projects build.gradle file

repositories {
    maven {  url 'https://dl.bintray.com/netguru/maven/' }
    ...
}

Add library dependency

    dependencies {
            implementation 'com.netguru.arlocalizerview:arlocalizerview:0.1.0'
    }

Add view to your layout

 <co.netguru.arlocalizer.arview.ARLocalizerView
        android:id="@+id/arLocalizer"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        />

In in arLocalizerView onCreate method you need to provide

interface ARLocalizerDependencyProvider {
    fun getSensorsContext(): Context
    fun getARViewLifecycleOwner(): LifecycleOwner
    fun getPermissionActivity(): Activity
}

fun arLocalizerView.onCreate(arLocalizerDependencyProvider: ARLocalizerDependencyProvider)

In order to process the permission request you need to provide permission results to the view.

    fun onRequestPermissionResult(
        requestCode: Int,
        permissions: Array<out String>,
        grantResults: IntArray
    )

Finally in order to display the destination labels on the camera preview use
```
arLocalizerView.setDestinations(destinations: List<LocationData>)
```
