Android app need to be built twice to avoid crash -
i'm facing issue don't understand @ all. have android app crash upon entering settings (crash log below), first time built. issue discovered while investigating why f-droid builds "faulty", while own worked fine.
the steps reproduce following:
rm -r ~/.gradle- ./gradlew assemblerelease && adb install -r ...
the build completes here, apk not work.
- ./gradlew assemblerelease && adb install -r ...
the second build completes, time crash not present anymore. has idea why such problem happening?
the issue can reproduced project located here. crash triggered entering settings. here full stack trace:

as @commonsware suggested, issue resolved disabling proguard release build. confirms source of problem, , work begin figure out if -keep option missing somewhere.
regarding reason why 2 subsequent builds not generate same apk, i'm afraid i'll never know.
