File opener issue for android marshmallow

I am using file opener plugin for opening a file. It works perfectly on pre marshmallow versions, but I am getting error for marshmallow. Below is the error
I have referred to all the solutions on the forum ,but none is working. Can anyone tell me how to solve the issue.

Posting error messages as images is impolite and impractical: Nobody can copy paste the error message to google for solutions.

Did not mean to be impolite and impractical by posting error messages as image, I am new to Ionic and the forum, anyways still looking for a solution for the file opener issue.

Step 1: Replace the error message by some text. Then maybe I or someone else can do some googling.
