Chartboost SDK & Proguard

UPDATE: This post (both issues) was made obsolete by Chartboost SDK 3.1.5. Follow the integration instructions supplied by Chartboost.

When using Chartboost SDK 3.1.3, ProGuard fails to compile with few warnings. To bypass this issue add the following lines to proguard.cfg:
# Chartboost
-dontwarn com.mongodb.tools.ConnectionPoolStat
-dontwarn com.mongodb.util.management.jmx.JMXMBeanServer
-dontwarn org.bson.types.ObjectId

IMPORTANT: If you're using mediation you might need to add more ProGuard exceptions.

Also, as of Chartboost Android SDK 3.1.3 there's a bug which prevent clicking Chartboost ads on Android 3.0+ (it will hang during the "Loading..." stage after the user clicks an ad). In the logcat the following exception appears: android.os.NetworkOnMainThreadException

Until Chartboost will fix it, just add the following patch to the onCreate method:

StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy); 

Note: this requires Android Platform SDK 9+
