UnityAndroidNativeToolkit 🧰

Created by Eric Batlle Clavero

This Android App made with Unity includes a complete AndroidToolkit plugin to allow Unity to use native Android OS features such as taking shots with the camera, pop dialogs, pick contacts, etc..

This repository is divided in 2 parts:

• Unity Project (C#)
• Android Plugin (Java)

Example 🎬

This image shows all UnityAndroidNativeToolkit features UI.

How to Use ⚙️

If you want to test the app, you can download the APK from here.

If you want to open the project and check the code, you need to have Unity and AndroidStudio installed and updated.

If you want to scratch the code:

• To check Unity project, open the project, select NativeToolkit scene. Either inside the unity project or simply dragging the .cs classes on your editor, you have to watch the classes located on UnityNativeToolkit/Assets/Scripts.
• To check Android Plugin you can do it opening the solution with AndroidStudio and checking the classes located in UnityNativeToolkitPlugin_Android\NativeToolkit\src\main\java\com\eric\nativetoolkit.

App Functionality is simple, just press the feature button you want to test. Some features like Dialogs also have toggles to specify some parameters.

On code side, the only thing to keep in mind is to make a Script (like NativeToolkit.cs in the example) that has a reference to NativeToolkitPlugin and initialize the plugin doing:

pluginReferenceVariable = NativeToolkitPlugin.GetPlatformPluginVersion(this.gameObject.name);

From here you can call all plugin features simply calling pluginReferenceVariable. and the feature you want, like

pluginReferenceVariable.TakeShot()

If you don't want to implement all features callbacks, remember to only implement the desired feature interface, like INativeCamera, instead of INativeToolkitPlugin. This last one implements all features interfaces.

Multiple plugins support 🔌

This plugin has been made following a fragment-pattern to avoid errors that can be derived from extending UnityPlayerActivity.

This way you can integrate this plugin with your projects even if they already have more plugins. Truly pluggable.

If you already have imported on your project the library core-1.3.1.aar or similar, remember to remove it, or remove the plugin one.

Upgrading dependencies 📜

Keep in mind that the actual release (v1.0) of the plugin works with AndroidX dependencies. That means that is targeting Android 9 (API level 28).
