Hi @bang919,

Thanks for reporting! I used the same device model, OS and library version (1.4.1), and repeated the provided steps for several times, but still couldn't reproduce. Did you change any configurations in DefaultLoadControl before seeing the issue?

Hi @tianyif ,

Thanks for the response! I haven't changed any configurations in DefaultLoadControl (see Fig. 1). After repeatedly opening and closing the ViewPagerActivity, I noticed that multiple PlayerViews persist, even after garbage collection has been executed. I'll attach a screenshot for reference.

Thanks @bang919 for the useful information!

I saw that the corresponding ViewHolders are still alive even when the ViewPagerActivity is stopped and GC is executed. I will provide a fix to this.
