Hi Terry,

Indeed there are potential issues when minifying with proguard an application based on the "full" version of LS Android SDK library.
We suggest excluding the class names from minification, as some parts of the library use Java reflection in a way that proguard may not detect.
We suggest adding the following restrictions in proguard-rules.pro (though narrower restrictions are certainly possible):

-keep class io.netty.** { *; }
-dontwarn io.netty.**
-keep class com.lightstreamer.** { *; }
-dontwarn com.lightstreamer.**

If small footprint is very important in your case, you can also consider the "compact" version of the LS Android SDK library.
See the library overview for details (https://www.lightstreamer.com/api/ls...client/latest/).

Regards,
Giuseppe
