App crashes on Android 2.3.x

[matthiaswenz]

Hi,
on any Android 2.3.x-devices my app crashes upon startup with the following stack trace:

3089-3089/net.hockeyapp.client E/AndroidRuntime﹕ FATAL EXCEPTION: main

Here's my environment:

• several Android 2.3.x devices (LG P970, 2.3.4, Genymotion Nexus One Emulator, 2.3.7)
• MSAI Android SDK 1.0 beta 2 / beta 4
• integrated via Maven

Please let me know if you need additional information.
Best,
Mat

This looks like it could be related to pro guard rules since the offending method is named "java.lang.NoClassDefFoundError: com.microsoft.applicationinsights.library.f"

I wrote the pro guard excludes before we refactored the code to match iOS architecture. We probably need to either update this file (https://github.com/Microsoft/ApplicationInsights-Android/blob/master/applicationinsights-android/proguard-rules.pro) to accommodate the new public interface or make an the class represented by "java.lang.NoClassDefFoundError: com.microsoft.applicationinsights.library.f" public so that the existing rule catches it.

The class in question is LifeCycleTracking - no need to make the class public, instead #48 should mitigate this issue.

Fixed in #48
