Android

This section of the User Manual contains documentation on developing for the Android platform,

Environment setup

Before you can run code on your Android device or an Android emulator, you must set up Unity to support Android development. See Android environment setup.

If you don’t install one or more necessary components during initial setup, Unity prompts you to download missing components when you try to build a Project for Android.

Building your app

Unity lets you configure build and runtime settings for your app. See Building apps for Android.

If you have a Unity Pro subscription, you can customize the splash screen that displays when the game launches. See Customizing an Android splash screen.

Scripting

Unity provides scripting APIs that allow you to access input data and other settings from Android devices. See Android scripting.

You can use plug-ins to call Android functions written in C/ C++ directly from C# scripts. You can also call Java functions indirectly. See Building and using plug-ins for Android.

Optimization

Unity includes support for occlusion culling, which disables rendering of objects when they’re not currently seen by the camera because they’re obscured (occluded) by other objects. This is a valuable optimization method for mobile platforms. See Occlusion culling.

Troubleshooting and bug reports

The Android troubleshooting guide helps you discover the cause of bugs as quickly as possible. If, after consulting the guide, you suspect the problem is being caused by Unity, file a bug report following the Unity bug reporting guidelines.

Texture compression

Ericsson Texture Compression (ETC) is the standard texture compression format on Android.

ETC1 is supported on all current Android devices, but it does not support textures that have an alpha channel. ETC2 is supported on all Android devices that support OpenGL ES 3.0. It provides improved quality for RGB textures, and also supports textures with an alpha channel.

By default, Unity uses ETC1 for compressed RGB textures and ETC2 for compressed RGBA textures. If ETC2 is not supported by an Android device, the texture is decompressed at run time. This has an impact on memory usage, and also affects rendering speed.

DXT, PVRTC, ATC, and ASTC are all support textures with an alpha channel. These formats also support higher compression rates and/or better image quality, but they are only supported on a subset of Android devices.

It is possible to create separate Android distribution archives (.apk) for each of these formats and let the Android Market’s filtering system select the correct archives for different devices.

Movie/Video playback

We recommend you use the Video Player to play video files. This supersedes the earlier Movie Texture feature.
