# Android/Kotlin

## Environment Set-up

### Overview

In order to build an `Android` app that uses HAT APIs you first need to install the **HAT API Android** library from [github](https://github.com/Hub-of-all-Things/HAT-API-Android). To do so you can either manually download the library and add it to your project or you can use maven \[*link coming soon*].

### Requirements

* Android studio 3.2
* Kotlin 1.3
* This guide does not show you how to set up the UI; you have to be able to design a basic UI in order to make everything work.

### Install manually

To manually install the library you have to download the repo from github and add it to your project via drag n drop.

### Install via Gradle

#### **Step 1**

In the top-level gradle file, add the jitpack repository link

```kotlin
allprojects {
  repositories {
    maven { url "https://jitpack.io" }
  }
}
```

#### **Step 2**

In your app level gradle file , implement the library dependency

```java
implementation 'com.hubofallthings.android.hatApi:hat:<latest-version>'
```

#### **Step 3**

Sync the project to download the library.

#### **Step 4**

Add internet permission into the AndroidManifest

```markup
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.hubofallthings.myProject">
/>​
```
