Problems with running app in android device

Hi! I am new in Expo and React native. I try to run my app in real android device using Expo QR-code and I have an error, don`t know how to solve it. If somebody has such experience, help me please!

  • I run my app by “expo start” and then I have this:

Starting Metro Bundler on port 19001.

Building JavaScript bundle: finished in 27369ms.

Building JavaScript bundle: finished in 22225ms.

Building JavaScript bundle: finished in 1337ms.

Building JavaScript bundle: finished in 1302ms.

Error starting tunnel ���⥬� �� 㤠���� ���� 㪠����� ����.

In my project log I see this:
“Tunnel URL not found (it might not be ready yet), falling back to LAN URL”.

Expo on my Android device showing this:
“Uncaught Error: java.net.ConnectException: Failed to connect to …”

My computer and Android device are using same WiFi connection…

How can I solve this problem and finally run my app on Android device?
