Not intalled application from F-Droid client android 4.4.2

I want to install the application from F droid but it can’t be installed and a fragment dialog appears that “Failed to install due to an unknown error”. I use an Android operating system with Kitkiat version 4.4.2 with a Huawei type device
EC6108V9-01 for TV Box. How do I solve this problem ???

This is a TV or what?

yes… I tried to install on a TV Box device like Apple TV but it has an Android operating system

There isn’t any chance to resolve this but through the logcat. Get it somehow.

The information in logcat is when onActivityResult always returns the default value in the resultCode. This problem was found in the DefaultInstallerActivity class
