Android Question

Android app launch first time launch is taking more time even some time 30 sec and more

Below is log when app is first time installing.

05-12 13:16:23.632 28250-28250/com.app.projectName W/System: ClassLoader referenced unknown path: /data/app/com.app.projectName-1/lib/arm
05-12 13:16:59.041 28250-28250/com.app.projectName W/System: ClassLoader referenced unknown path: /data/app/com.app.projectName-1/lib/arm
05-12 13:16:59.073 28250-28250/com.app.projectName I/MultiDex: VM with version 2.1.0 has multidex support
05-12 13:16:59.073 28250-28250/com.app.projectName I/MultiDex: install
05-12 13:16:59.073 28250-28250/com.app.projectName I/MultiDex: VM has multidex support, MultiDex support library is disabled.


And I am using Multidex library in my project it will work completely below pre lollipop devices.This delay varying in Lollipop devices between 30 sec to 90 sec first time app start up.

See it is not due to multidex right? because when time is 1.) initializeing 05-12 13:16:23.632 and second log comes after 36 second which is 05-12 13:16:59.041

That thing creates app delay classLoader referenced.... Multidex is initialising fast. Below is the screen shot enter image description here It is taking 15 seconds to 30 seconds and sometime even more.

My Gradle file is:

Answer

Finally found answer after more then 16 days all thanks to you @Amir. Correct answer is to disabling instant run then run. There is a strange issue with newly released Android Studio 2.0 & 2.1. first time of launching application take longer than usual this issue happens only in debug mode and not effect your released APK.

Settings/Preferences(Mac) → Build, Execution, Deployment → Instant Run and uncheck Instant Run
