Hi，I have meet same problem before, and I was able to resolve it by following these steps. (maybe it could help you or someone who have face the same issue)

1. check if your device have the minicap file. The installation can see :https://github.com/DeviceFarmer/minicap
2. check the apk file can install successfully on the device, you can manually drag the apk file to the device to valid.
