Proguard

In case you are using Proguard, you will need to whitelist MPAndroidChart, which requires to add the following line to your Proguard configuration file:

-keep class com.github.mikephil.charting.** { *; }

If you don't do this, animations might not work.

If you are having issues with the Realm.io classes, add the following to your config file:

-dontwarn io.realm.**
