My app is taking 10-12 sec delay while first load on 5.0+ devices, 4.4 or below devices does not have this problem. I have added a log message in Application class onCreate method but it is also called after 10-12 sec seconds. I have tried multidex enable false, minify enabled true but does not make any difference. I have found one thing, when we clear cache and data from app info activity, then it again delay while loading and my app is taking around 10mb of cache and 5 mb of data which is higher than usual. How to address this problem? I have not find this type of issue on net or stackoverflow
It happens when you enable Instant Run in Android Studio. Try disabling instant run and check. It happens only in debug builds
