Android, ProGuard, and keepclasseswithmembernames

Question

A common pattern in ProGuard configs for Android applications is to preserve custom View classes, since they are probably referenced only from layout XML instea

Answer 1

When I first tried the integrated proguard with Ant, my app kept crashing with runtime errors on the clickhandlers. (I always set these in XML). I assumed I must be doing something wrong, couldn't work out what, so added the line

-dontshrink

at the top of the proguard.cfg.

Maybe this isn't optimal but it stopped the run time errors!

Addendum

In fact I checked this by looking at usage.txt. The clickhandlers were listed in there before I added the dontshrink option, after I added it, usage.txt was empty as would be expected.
