Android Things - Raspberry Pi Fails to Connect to Wifi

Question

There are a few questions out there that have similar issues but none of the solutions help. I'm trying to connect an Android Things Raspberry Pi to Wifi. My 2.4 GHz wifi ssid is 'cake' and I even removed the passphrase to see if that would help. Here is what comes out in the logcat:

Here is what I'm typing in the adb shell

rpi3:/ $ am startservice -n com.google.wifisetup/.WifiSetupService -a WifiSetupService.Connect -e ssid cake

I had also some issues setting up the Wifi. Blundell's answer to my question solved the issues

Network: Wi-Fi cannot connect to the internet if Ethernet is also connected to a network without internet access.

I had to remove the Ethernet cable from the Pi-3 and then it connected to my WiFi

If you have no application installed on the Pi you can observce your connectivity state by attaching an external display using the HDMI port (a monitor would do the job).

You should see a screen like this:

Yeah but how did you discover the IP address after you removed the ethernet cable from it?

dudeldidadum Over a year ago

The easiest way: You could connect your raspberry via hdmi to monitor

That did it! Thanks...such a ridiculous thing to not mention in the docs.

This trick works on the NXP i.MX7D Android things development kit as well. Thanks!
