Note about JNI and Proguard

[netshade]

Just a note for anyone else that may have encountered this: when running quickjs-android in a build that includes ProGuard, symbol information is discarded. This will cause the library to be unable to successfully complete JNI_OnLoad due to symbol lookups it performs.

In order to keep the symbol information so that JNI can initialize correctly, you will want to add the following rules to your proguard config:

-keep class com.hippo.quickjs.** { *; }

This will keep all symbol information in the library - you could be more selective here, but I opted to allow for everything to be retained in case there were any dependencies I wasn't aware of.
