Answer 1

The Instant Run is enabled in your Android Studio. Try to disable the function. You will not get that issue.

Why does my App start incredibly slow (10s+) at first run, showing only white screen on android 5.0?

@DaxeshVekariya, I guess what Dave mentioned is minify enabled build. (debug built apk is also signed with debug keystone) – Efface

If you have an image which shows in splash screen and if there is only single density image, put it in drawable-xxxhdpi folder.

this is not my problem, I enabled insta run after disabling its fine. – Rorrys

Yes Instant Run also causes trouble. – Chaworth

Answer 5

In my experience, Fabric consumes a bit of time in establishing the connection and communicating.

I would suggest you to comment the Fabric portion on the code and re-run to see if there is any change in the app load time.

Additionally u could move the code on to an async task rather than performing these on the main thread. It would at least not slow down ur initial app launch time.

In my case, it was due to instant run enabled. Though this works fine on the latest android version 4.1.1
