React Native Metro Bundler not starting automatically

Question

I'm using mx Linux which is Ubuntu derivation. Trying to use react-native with genymotion. I did all installation right I suppose.

Android studio latest with some SDK.

Configured PATH like

    export ANDROID_HOME=$HOME/Android/Sdk
export PATH=$PATH:$ANDROID_HOME/emulator
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH:$ANDROID_HOME/platform-tools

Nodejs version 10.21.0 (tried 12.4.0 and latest also.But result is same ) npm version 5.8.0 (tried newests but same)

Genymotion settings (For SDK path ) done like that

 /home/kaan/Android/Sdk/

And here is the result. Metro bundler didn't run as aspected as automatically.

I started npx react-native start its working but when I change something it's not updating because npx react-native run-android finished as you see on top.

Did anyone face this problem before ? And anyone can solve this?

There is no solution except running metro bundler manually. Thanks!
