MultiDexTest

This app was written to reproduce a bug in Android build tools.

Reproduce environment

1. Gradle plugin: com.android.tools.build:gradle:0.14.0
2. Compile SDK: android-21
3. SDK Build tools: 21.1.0
4. SDK tools: 23.0.5
5. SDK platform-tools: 21
6. Ubuntu & Android Studio 0.9.1

Bug description

In latest SDK build tools, we can use the dx parameters '--multi-dex' & '--main-dex-list' & '--minimal-main-dex' to generate and control multiple dex files in APK. If these parameters were used, the expected dex files will be generated, it's great. But in the final APK, the dex files' names were changed.

From the following operation logs, you can see that the "classes*.dex" names in the final APK were exchanged!
