Thread Warnings on xcode

I’m testing my app on my device, and while its building I see a few warnings on xcode like this:

2017-02-03 05:35:57.807700 myFrame[3592:875108] THREAD WARNING: [‘StatusBar’] took ‘19.945801’ ms. Plugin should use a background thread.

2017-02-03 05:35:57.839501 myFrame[3592:875108] THREAD WARNING: [‘ImagePicker’] took ‘24.204102’ ms. Plugin should use a background thread.

is this ok or do I need to change any settings?

Thanks
