Game not launching on Android

Hello, I am trying to launch my game on my Nextbit Robin phone. I followed the instructions here Android Quick Start | Unreal Engine Documentation and that worked fine. But when I try launch my own project, when it gets to “Launching on “device””, it hangs and the log just repeats:

<>c__DisplayClass65_0.b__0: Waiting for server to start…

But I can’t tell why.

Uploaded the log file here

I have a similar problem. I am trying going to C:\NVPACK\android-sdk-windows\tools and running android.bat and making sure all that stuff is installed. Hope that works…
