Better error message for not connecting to Android debug device - WIFI debugging #154545

Open FMorschel opened 3 months ago

FMorschel commented 3 months ago

Steps to reproduce

  1. Connect a physical Android device to debug
  2. Leave it there unattended for some time until it shows on flutter doctor -v that it is offline (maybe only happens on wifi debugging?)
  3. Try to debug a project with flutter run -v
  4. See the output below (logs).

About point two here, not sure this is exactly when you can see this output. Look https://github.com/Dart-Code/Dart-Code/issues/5245 for more info. It happens to me whenever I have left my phone lock the screen by itself and have not used it for some time. If I lock it manually or recently this does not happen.

Expected results

Device is offline message. Or some better message handling when not in verbose mode.

Actual results

Connection closed before full header was received message only in verbose mode.

Hi @FMorschel, curious, what device are you using? And is that the only device you're seeing this on? I have been trying to get my pixel 7 to read as offline, but after the phone locks for several times, it is still able to connect

I've used a Samsung Galaxy S23U and had this experience but currently downgraded to see the behaviour on older devices and am using a Samsung Galaxy S20 FE. Not sure if this is only a Samsung thing. As I said on the issue for Dart-Code, it seems weird that the phone receives the app and installs it just fine bit is not able to connect to the service protocol.

As I said, it is pretty inconsistent as well. I'm not really sure how to make this happen. The one thing I noticed is that I connect it through wifi debugging and leave the phone locked for some time while doing other things (not deving or deving without debugging) and whenever I come back, I always need to manually unlock my phone to make debugging work.

I'm guessing this might be because adb might be dying on us. Possibly related https://github.com/flutter/flutter/issues/9707

Labeling this as a proposal for an improved message.
