Class not found exception when using LiquidCoreAndroid with proguard

[martinspaeth]

Hi there,

When using the LiquidCore lib while proguard is activated will fail.

To solve one just need to add a simple proguard keep rule:
-keep class org.liquidplayer.javascript.** { *; }

May this could be part of the Library itself

Sample stacktrace for one running into the same issue:

Thanks for reporting. I will add a proguard rules file to the library.
