Problems with ADB and launching project in UE4.

Hey Sugunwar, if your UE configuration is OK as suggested by wittlief, it could be an issue with ADB. ADB has a tendency to work great for small tasks, then explode in your face when you tax it heavily in some cases. Often a cable will work to charge or do small operations, but not transfer large amounts of data reliably. I’d recommend you try either a different combination of cable/USB port, or connecting over wifi:

#plug in USB cable
#run this and get your device’s IP address from the output
adb shell netcfg

#restart ADB in network mode:
adb tcpip 9999

#unplug USB cable
#use this command to connect ADB over your network:
adb connect 192.168.1.x 9999
