Android Error : IPerf::tryGetService failed

Question

I am developing a simple Android app. In my app I implement a toolbar and an actionbar with a ViewPager for doing swipe between fragments, I am using a RecyclerView to fill a list of movie and everything goes fine.

The app doesn't crash but in the Log Cat appears a constant error every time I am scrolling over the list and swiping between fragments and I notice that my app runs slowly and has a terrible user experience.

Any luck by figuring out what is going wrong by using the official profiler in Android Studio? – Hautbois

The slowly behavior is more likely because of [How you fetch the recyclerView], as I understood u should be fetching data from internet to recyclerView, does it happen in background ?. what library u use for requesting data ?. do you request all data items or just the first 10 items and when scroll another 10 items are requested ? – Scholiast

Have you tried to reproduce this same behaviour on other devices/emulators? In my experience some android devices tend to be quite verbose when it comes to errors not specifically related to application code. – Larry

Can you please post the relevant code? – Ritter

IPerf is not responsible for your slow app perfomance.Make Recyclerview smooth scrollable and use ` android:nestedScrollingEnabled="false"` inside your recyclerview. – Etan

Did you get any solution for this? – Syce

@MohamedEmbaby hi, I am getting same error and I am using volley and yes, I am facing 20 objects at a time. – Syce

@Ancee request 10 items and when user scroll to last item request 10 more – Scholiast

E/ANDR-PERF: IPerf::tryGetService failed!

I also got the above error too, but after a while, I realized that it was occurring because my code was trying to get some data from an API.

I hope this might give some idea to you, I know it's too late to answer but it might be helpful for those who are searching and land here.

Best regards.

that it was occurring because my code was trying to get some data from an API??? this is what i want my code to do do you say that i have to stop fetch data from the api to make this error disappear? – Bladdernose

No, I just mentioned the reason of the error. It means fetching fails because of wrong link/credentials or slow connections between them. It might even caused by another reason but code might be reviewed for that. Sorry I don't remember how i solved mine; It was jun '19. @Sideeg MoHammed – Kipkipling
