Exception when running default app on Samsung Galaxy Note 5

Error message

Seeing a strange behavior for the Galaxy Note 5 only when running the hello world application created by running flutter create. After a reboot of the phone, I can launch the application as expected. But trying to run the same application again for the 2nd time, the app gets stuck at the Flutter Debug Loader screen, with the message: "This is a hot-reload-enabled debug-mode Flutter application...".

The behavior is tied to the hot reload feature, when I disable it by using flutter run --no-hot, everything is working fine on the Galaxy Note 5.

Exception / error message shown: I've seen this exception a couple of times, but that doesn't seem to be the main problem, since the app get's stuck with different error messages as well.

On an Nvidia Shield tablet or Lumigon T3 Android phone everything is working fine. These are the engine and framework revisions:

Framework revision 6777766 (57 minutes ago), 2016-10-11 15:51:35
Engine revision e8d046e

When running the app as a release using flutter run --release, it launches as expected.

Steps to Reproduce

On a Galaxy Note 5 (Android 6.0.1, build MMB29K.N920SKSU2BPH3), run the following steps:

Reboot the phone
Create a new default app using flutter create helloworld.
Run the app by executing flutter run lib/main.dart or flutter run: Application should run as expected
Stop the app and run again: Application launches with black screen, or with the "Flutter Debug Loader" screen (This is a hot-reload-enabled debug-mode Flutter application...").
Now run the app with hot reload disabled: flutter run --no-hot, and the app will load again.

flutter run -v output:

For extra long logs like this gist.github.com can be useful for taking them out-of-band. :)

Looks like the first exception was:

@Hixie

Presumably that's a bug in TextPainter? @Hixie

Moved the log files into gist.github.com. Updated the description with more details after more testing. Was never able to reproduce that behavior on the two other Android devices I'm testing with.

@johnmccutchan

@johnmccutchan the updated description suggests maybe hot reload is failing on the note 5?

@Hixie

@Hixie the DevFS failure in the log is a result of the VM process dying while we are copying files.

@raju-bitter Do you have any idea what all the filesystem errors (ENOTEMPTY, ENOENT) are coming from? I've never seen that and it appears to be coming from the Android system directly.

@eseidelGoogle

@eseidelGoogle Do we have a Galaxy Note 5?

We have a Note 3 and a Galaxy S5.

Did a factory rest of Galaxy Note 5 and tried again. Same behavior as before, here are the log files:

Testing flutter.io on Galaxy Note 5 after factory reset, 1st run of app with one hot reload

https://gist.github.com/raju-bitter/b3ac3e535cb5cd5e19b421c840c4d547

The 2nd time I'm running the app, I can see this extra exception:

Exception from flutter run: HttpException: Connection closed before full header was received, uri = http://127.0.0.1:8102/ws

https://gist.github.com/raju-bitter/b3ac3e535cb5cd5e19b421c840c4d547#file-flutter-run-log-galaxy-note5-factoryreset-second-run-log-L911

Thanks for double checking. I'll purchase a Note 5 right now.

Update: phone ordered. :)

This also repros if you run a Flutter app from the IntelliJ plugin against a Nexus 5X (but not if you run that same app against that same 5X from a terminal with flutter run): flutter/flutter-intellij#289.

Some kind of timing issue?

@mit-mit

I can also reproduce this problem on a Nexus 5X using flutter daemon; see my comment in the bug @mit-mit referenced.

@raju-bitter

@raju-bitter On the second run the HttpException is caused by the app on the phone crashing. It's unclear why it is crashing, I'm trying to reproduce locally with no luck. Could you gather the full logs from 'adb logcat' ? It might give us a clue about where the crash is occurring.

Looking at the logs I noticed the first error:

It's unclear from the stack trace what is happening but this happens before we even create the DevFS environment.

@raju-bitter

@raju-bitter I have made a change to flutter tools that will hopefully give a better stack trace for the above error. Could you sync to the latest master and try again?

@johnmccutchan Did another test run with today's version

Here is the complete log after rebooting and launching the Flutter app two times. First time reloading is working. Second time stuck, Flutter exception highlighted:

Thanks! Our Note 5 arrived, and it's on John's desk :)

I can confirm that I can reproduce the failure as described. It's flaky but I can make it happen.

Initial investigation points at a low level networking failure between the host machine and the phone. We fail to make the initial service protocol connection. The client receives and HTTP error but the server (running on the phone) never sees the connection attempt. Possibly something bad is happening at the adb level.

I've figured out what causes this problem: we get stale device logs and try and use the previous launch's service protocol port.

After a few attempted runs, I see the following from adb forward --list. Note the repeated device ports.

Nice! Thanks for tracking it down :)
