Why AssetManager creation takes tooo long to load that make application start slow

Question

I am making an android app. When I compile and run it (even when I copy and paste apk on device and run) it takes too long to start and show me my first activity. I debugged logs and found that 1st log as follow takes like 20 seconds then from there after approx 20 seconds I get later logs and app runs.

First log of app:

5-19 18:41:42.816 29232-29232/com.softinator.mantrafm D/ResourcesManager: creating new AssetManager and set to /data/app/com.softinator.mantrafm-2/base.apk

Answer 1

I was also facing the same problem. Thanks to one of my teammate, basically you'll have to disable "Instant Run" if you are using gradle 2.x

I installed android studio v2 and suddenly this problem came up. So basically before giving apk may it be debug apk or production apk, go to Settings -> Build, Execution, Deployment -> Instant Run and uncheck "Enable Instant Run to hot swap/resource changes on deploy". You need to disable that and then build apk and give it to somebody else or use yourself.
