startIntent with documents

Question

I have a problem, I have this code.

Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.setData(Uri.fromFile(file));

        intent.setType("application/*");
        startNewActivity(intent);

I opened Documents but throws me an error , saying Documents has closed unexpectedly.

But on the other hand , if I navigate to the file location and I open it, Documents, opens me perfectly .

I trace capturing the whole I find this phone .
