emulator times out on mac android studios

I also tried with 'Tunnel' and 'local' connection types too and in both case, I can see JSON response from my emulator browser, but expo-client is faced with an error. When I go to '192.168.43.188:19000' in my browser (on android studio emulator and my real device), I can see the JSON response (it takes about 25 seconds). How do I get rid of the default app header in Android Studio 380 Views. '192.168.43.188' is my correct host IP and my laptop and my device are in a same network. This message comes when your emulator going to launch.Normally it take some time. I installed the expo client on my real android device and android studio simulator, when I click on 'run on android/device emulator' or when I scan the QR barcode from my device, the expo client is run successfully but the error message is appeared: 'Could not load exp://192.168.43.188:19000. The expo was run successfully and expo developer tools was run in the browser. Then I used 'expo init' for creating a new project.

I installed node v10.15.1 and then I install expo-cli: 'npm install -g expo-cli'.
