Unity3D Game Build to Android

Original Source Code from Unity Technologies.

Getting Started with Android Development

Building games for a device running Android OS. However, the hardware is not completely standardized across all devices. There are some feature differences in the Android version.

Setting up your Android Developer environment

You will need to have your Android developer environment set up before you can test your Unity games on the device. This involves downloading and installing the Android SDK with the different Android platforms and adding your physical device to your system (this is done a bit differently depending on whether you are developing on Windows or Mac). This setup process is explained on the Android developer website, and there may be additional information provided by the manufacturer of your device. Since this is a complex process, we've provided a basic outline of the tasks that must be completed before you can run code on your Android device or in the Android emulator. However, the best thing to do is follow the instructions step-by-step from the Android developer portal.

Access Android Functionality

Unity Android provides scripting APIs to access various input data and settings. You can find out more about the available classes on the Android scripting page.

Exposing Native C, C++ or Java Code to Scripts

Unity Android allows you to call custom functions written in C/C++ directly from C# scripts (Java functions can be called indirectly). To find out how to make functions from native code accessible from Unity, visit the Android plugins page.

Occlusion Culling

Unity includes support for occlusion culling which is a particularly valuable optimization on mobile platforms. More information can be found on the occlusion culling page.

Splash Screen Customization

The splash screen displayed while the game launches can be customized - see this page for further details.

Troubleshooting and Bug Reports

There are many reasons why your application may crash or fail to work as you expected. Our Android troubleshooting guide will help you get to the bottom of bugs as quickly as possible. If, after consulting the guide, you suspect the problem is internal to Unity then you should file a bug report - see this page for details on how to do this.

How Unity Android Differs from Desktop Unity

Strongly Typed JavaScript

For performance reasons, dynamic typing in JavaScript is always turned off in Unity Android, as if #pragma strict were applied automatically to all scripts. This is important to know if you start with a project originally developed for the desktop platforms since you may find you get unexpected compile errors when switching to Android; dynamic typing is the first thing to investigate. These errors are usually easy to fix if you make sure all variables are explicitly typed or use type inference on initialization.

ETC as Recommended Texture Compression

Although Unity Android does support DXT/PVRTC/ATC textures, Unity will decompress the textures into RGB(A) format at runtime if those compression methods are not supported by the particular device in use. This could have an impact on the GPU rendering speed and it is recommended to use the ETC format instead. ETC is the de facto standard compression format on Android, and should be supported on all post 2.0 devices. However, ETC does not support an alpha channel and RGBA 16-bit will sometimes be the best trade-off between size, quality and rendering speed where alpha is required.

It is also possible to create separate android distribution archives (.apk) for each of the DXT/PVRTC/ATC formats, and let the Android Market's filtering system select the correct archives for different devices (see Publishing Builds for Android).

Movie Playback

Movie textures are not supported on Android, but a full-screen streaming playback is provided via scripting functions. To learn about supported file formats and scripting API, consult the movie page or the Android supported media formats page.

Android SDK Setup

There are some steps you must follow before you can build and run any code on your Android device. This is true regardless of whether you use Unity or write Android applications from scratch.

1. Download the Android SDK

Go to the Android Developer SDK webpage. Download and unpack the latest Android SDK.

2. Installing the Android SDK

Follow the instructions under Installing the SDK (although you can freely skip the optional parts relating to Eclipse). In step 4 of Installing the SDK be sure to add at least oneAndroid platform with API level equal to or higher than 9 (Platform 2.3 or greater), the Platform Tools, and the USB drivers if you're using Windows.

3. Get the device recognized by your system

This can be tricky, especially under Windows based systems where drivers tend to be a problem. Also, your device may come with additional information or specific drivers from the manufacturer.

For Windows: If the Android device is automatically recognized by the system you still might need to update the drivers with the ones that came with the Android SDK. This is done through the Windows Device Manager.

If the device is not recognized automatically use the drivers from the Android SDK, or any specific drivers provided by the manufacturer.

Additional info can be found here: USB Drivers for Windows

For Mac: If you're developing on Mac OSX then no additional drivers are usually required.

Note: Don't forget to turn on "USB Debugging" on your device. Go to , then enable USB debugging. As of Android Jelly Bean 4.2 the Developer options are hidden by default. To enable them tap on multiple times. Then you will be able to access the .

If you are unsure whether your device is properly installed on your system, please read the trouble-shooting page for details.

4. Add the Android SDK path to Unity

The first time you build a project for Android (or if Unity later fails to locate the SDK) you will be asked to locate the folder where you installed the Android SDK (you should select the root folder of the SDK installation). The location of the Android SDK can also be changed in the editor by selecting Unity > Preferences from the menu and then clicking on External Tools in the preferences window.

NFC is a type of RFID.
RFID tech is being used increasingly for identification & financial transactions.
As keys to open locks of all kinds.
As the mobile phone has become a “convergence” device for other portable electronics,
so too it may become a universal “keyring” for RFID applications

Android NFC Development

NFC Basics

This document describes how Android handles discovered NFC tags and how it notifies applications of data that is relevant to the application. It also goes over how to work with the NDEF data in your applications and gives an overview of the framework APIs that support the basic NFC feature set of Android.

Advanced NFC

This document goes over the APIs that enable use of the various tag technologies that Android supports. When you are not working with NDEF data, or when you are working with NDEF data that Android cannot fully understand, you have to manually read or write to the tag in raw bytes using your own protocol stack. In these cases, Android provides support to detect certain tag technologies and to open communication with the tag using your own protocol stack.

NFC Basics

This document describes the basic NFC tasks you perform in Android. It explains how to send and receive NFC data in the form of NDEF messages and describes the Android framework APIs that support these features. For more advanced topics, including a discussion of working with non-NDEF data.

There are two major uses cases when working with NDEF data and Android:

Reading NDEF data from an NFC tag
Beaming NDEF messages from one device to another with Android Beam™

Reading NDEF data from an NFC tag is handled with the tag dispatch system, which analyzes discovered NFC tags, appropriately categorizes the data, and starts an application that is interested in the categorized data. An application that wants to handle the scanned NFC tag can declare an intent filter and request to handle the data.

The Android Beam™ feature allows a device to push an NDEF message onto another device by physically tapping the devices together. This interaction provides an easier way to send data than other wireless technologies like Bluetooth, because with NFC, no manual device discovery or pairing is required. The connection is automatically started when two devices come into range. Android Beam is available through a set of NFC APIs, so any application can transmit information between devices. For example, the Contacts, Browser, and YouTube applications use Android Beam to share contacts, web pages, and videos with other devices.
