I have a Jadoo4 USB stick that runs on Android, similar to Chromecast. It has an app to watch live TV from East Asia.

I made an APK of that app, but whenever I try to install it on other devices (like my phone), it fails. This is the error that I get on my phone.

The app is provided by the producer. And I don't know if it's specially made for the device. The device doesn't seem very special. It's like a USB/Chromecast but running full Android on it.

The device that runs the app has Android KitKat on it. On my phone, I run Android 7.1. I even tried to install the app virtual Android 4.4 (VirtualBox). First, it seemed that the installation was successful, but after 1 minute, I got the message that the installation failed. On the virtual machine, the error is just "App installation failed".

Any idea why that might be?
