Question

I am new react-native and just ran my first hello world app using a real device using Expo.

Now, I would like to run first hello world app on an android emulator. I setup an AVD using AVD Manager from Android Studio. (Marshmallow)

But, every time the bellow error happens.

I can't find the fix for this.

Any clue is much appreciate. Mike

To view your app with live reloading, point the Expo app to this QR code.
You'll find the QR scanner on the Projects tab of the app.

EDIT

This is the SS....

And I get the below error ....

Or enter this address in the Expo app's search bar:

  exp://192.168.1.35:19000

Your phone will need to be on the same local network as this computer.
For links to install the Expo app, please visit https://expo.io.

Logs from serving your app will appear here. Press Ctrl+C at any time to stop.

Error running adb: socket hang up

The device itself is recognized anyway, so that problem is solved, I just had to fix the path to same ADB as the android studio....see below:

mike@mike-Laptop:~/Desktop$ adb devices
List of devices attached
emulator-5554   device

thanks for your comments anyway....

EDIT

I followed the link in the error message it turns out I had not installed "apt-get install android-tools-adb". So I installed it and then ran when I had two devices connected (an actual Nexus 5 and a AVD Nexus 6.):

mike@mike-Laptop:~/Desktop$ adb devices 
adb server is out of date.  killing...
* daemon started successfully *
List of devices attached 

mike@mike-Laptop:~/Desktop$ 

Note that using Expo everything works just fine. I just want to be able to use an emulator (Whether Android or Gynomotion) for the sake of development.

EDIT

I managed to connect an actual device using USB. Tried

sudo adb kill-server 
sudo adb start-server 

But, it was very slow ...it took 10mins to show up the app on the device (Nexus 5).

But still having problem with running things on Emulator. It give the below error:

Error running adb: socket hang up

EDIT

Dear Gavin,

Below is the snapshot of what I have on my Andr. Stdu. ...

I look forward to hearing your comments... thanks very much indeed

Answer 1

You need to actually launch your virtual device in android studio. While AS is open, click the emulator (looks like phone) button in the top right, it will launch the emulator if you're setup right, then you can run react-native run-android
