File-transfer plugin slows the start of the app

I am developing an app who use the file-transfer plugin and when I install in android the start speed is very slow (more ore less, one minute to start).
I was creating different projects with the different plugins and discover than the file-transfer is the problem.
Creating a blank project and installing only the file-transfer, without other plugins ore code, and slows the start of the app.
I tried it on a LG g5 with an 7.0 Android.

Someone knows what could be the problem?
