Pick json from local drive and decode it

Hi everyone.

I want to create an app that will open file manager and after choosing a json. The app should open it but I am having a challenge after it opens the file manager, you select the file, the file is not opening

Well, you are not opening the file. You, as a minimum, need to use the File component to read from a text file, this is assuming that the activityStarter is returning a valid file path.
