Building my Unity 3.4 iOS app on Android for the first time blog - Gamieon

Since I bought the Unity license to do so, I decided to see what happens if I build and deploy Hyperspace Pinball, which has been out on the App Store for a while, onto my HTC Thunderbolt. I wanted to do so without changing anything in the Unity project except for target platform and OpenGL version (1.x) just to see what would happen.

First, I found some great tutorials to get me started:

YouTube Tutorial: Getting Started with Unity3D for Android by Dr. Brian G Burton (Part 1 of 2)
Youtube.com

Tutorial: Getting started in the market
Unity3d.com

After doing some watching and reading, I did the following in order:

1. Installed HTC Sync to make sure my device was talking to my computer without problems. I never used it before because I really just use my phone for calls, web surfing and development.
2. Changed my phone to be in "HTC Sync" mode when I plug it in
3. Made sure I could get it to sync by syncing some music.
4. Installed Java JDK from Oracle.com
5. Installed Android SDK  http://developer.android.com/sdk/index.html
6. Fired up Unity, opened Hyperspace Pinball, set target platform to Android, forced OpenGL 1.x, and pressed the magic build button.
7. Kept getting build errors; something about a value not in an expected range (-1).
8. Uninstalled HTC sync. Error gone.
9. New error: Building DEX Failed! java.lang.IllegalArgumentException: already added: Lcom/heyzap/sdk/ClickableToast$1;
10. Fixed the error by deleting all my HeyZap jar files from my Plugins/Android folder in my Unity project. I'm not ready to integrate HeyZap for Android yet anyway; I have a ton of other things to learn and do first.
11. Build succeeded, and ran on my phone!

Two problems I saw in the game off the bat:

1. Game play was actually a bit sluggish!!! This is intolerable. I must find out why.
2. Hyperspace Pinball has two of every font; one is regular size and one is half size. I decide which fonts to use based on the device's resolution (specifically, a width of 320 uses the half-size ones, the rest use the default size. It's ugly, but I have no better solution yet). Anyway, the fonts are too big on my Thunderbolt, so I need to figure out what to do about that.

Will post more blogs as I learn how to publish apps and integrate banner ads.
