npx react-native run-android: E/Device: Error during Sync: EOF

Question

I am trying to run react native app to my real android device. I checked my device before running

adb devices

List of devices attached
3357425441473098        device

I started with

npx react-native start

and in other console

npx react-native run-android

But got an error..

And right after that error. I lost my device connection.

adb devices

shows nothing..

and at the bottom of stacktrace I see this error also

My device is us samsumg galaxy s9. It was working when I use Expo sdk. What is my problem?

react-native : 0.61.5

Weird thing is that it works first execution after computer boot. then I tried reconnect phone, and it pops up again.

Answer 1

I had a similar issue. I noticed that the USB configuration defaults back to No data transfer every time I connect it with an USB-cable. It even seems to happen sometimes when the cable is still connected.

You can change the default USB configuration in the developer settings:

Go to Developer Options > Default USB configuration > and change the setting to File Transfer / Android auto

Answer 2

Just had the same problem. Turned out it was an issue with my USB cable. For some reason the installation process was being interrupted half way through by the device going offline. I've replaced the cable, and everything started working again.
