Cannot start my react-native application on Genymotion with expo

When I try to start my react-native application on Genymotion, it shows:

Error running adb: 'Error running app. Error: Activity not started, unable to resolve Intent { act=android.intent.action.VIEW dat=exp://192.168.56.1:19000 flg=0x10000000 }'

Yet when I tried to start Java application, everything works well. I searched the web I found some tips but nothing.

My environment :
