Cordova file plugin warning


I have the following warning when staring my app.

2018-06-14 14:28:44.721086+0300 domovea v2[2995:1364159] THREAD WARNING: [‘File’] took ‘13.257080’ ms. Plugin should use a background thread.

The problem is because of this the application does not fully load because i am setting the background from a local file. And when I navigate to another page not all controlls are being loaded. I haven’t found anything to help out. I am trying to build on iOS.

Thanks in advance.
