Failed to open trivial text file with FileProvider

Question

I'm crazy, I used the new Android FileProviderin the past, but I can’t get it to work with the (trivial) file just created in the Download folder.

In mine AsyncTask.onPostExecuteI call

Intent myIntent = new Intent(Intent.ACTION_VIEW, FileProvider.getUriForFile(mContext, BuildConfig.APPLICATION_ID + ".fileprovider", output));
myIntent.setType("text/plain");
myIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(myIntent);

My FileProvider XML file is similar to this

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="Download" path="Download"/>
</paths>

In the Genymotion emulator, I always get by choosing Amaze Text Editor as the target application:

So far I see the contents of the file using the HTML Viewer:

I can not understand this behavior and fix what should be a trivial task, for example, to open a file with clear text using the requested text editor.

thanks a lot Nicola
