Folders & Devices Screen stays empty

[yeus]

I have a Huawei P Smart and Android 8.0.0.

The "folders" and "devices" screen stays empty. Also, the app crashes when I add a new device after putting in the ID.

I am pretty unexperienced regarding android is there any way I can help to debug this?

[Nutomic]

Did you download the app from Google Play, and send the crash report? That would be the easiest way to get the log.

[Pazuu]

Same here, just send the crash report. I think this is new since 0.3.4. thank you!!

[Pazuu]

I dont know whether this is important or not, but if i add a device the app crashes and there is no popup asking me to send a report via google play. But if i use the option to clear the index and cache the app crashes and i can send a report via google play (what i did).

[Nutomic]

@Pazuu No idea why that happens.

@l-jonas I think this is the correct crash report from Google Play. I can also give you access so you can view the reports yourself.

@Pazuu Does the crash happen in the setup wizard or when adding devices later in the App? (Or is it at both?) (the crash report above is for the setup wizard and looks like it's caused by a configuration change (screen rotation))

@Nutomic For the crash report access: Can I send you my google account id using the mail address which is at the bottom of https://nutomic.com/?

[Pazuu]

The crash happens after adding a device later (not in the wizard), as soon as this device (e.g. a laptop) accepts the syncthing lite smartphone and starts to establish a connection.

[l-jonas]

@Pazuu If you reset the App and add the device which you now added later as the first device, does it occur again then (or only if you later add the device which you now added as first device)? Is there really no way to send a crash report for this/ did you download the App from Google Play?

[Pazuu]

You are right, i experience the same crash equally if i add the first device in the setup wizard (as soon as it (e.g. laptop) tries to establish a connection) or if i add it later.

I am very sorry, i downloaded the app via google play, but it does not ask me to send a report after that crash (different to the "clear index crash")

I am using a Fairphone 2 with Android 7.1.2 (had the same crash with Android 6)

[l-jonas]

@Pazuu This sounds like your issue should be fixed with #91 (which is not yet part of a released version). Moreover, I created #102 because there could be other cases when crash reports are needed without relying on Google.

[Nutomic]

@l-jonas Yes, that would be perfect.

[Pazuu]

I am sorry, but i still experience the same crash with version 3.5 and i "turned on" the new built in Custom Crash-Handler, but it does not copy a log to the clipboard after this particular crash. After adding a device, the device view stays empty and the app crashes, as soon as the device accepts the syncthing lite smartphone and connects.

[l-jonas]

@Pazuu Then I know that the crash happens at the IndexHandler (and this component is currently beeing rewritten). There, the (old) function Executor.submitLogging is used which does a custom exception handling which does not redirect the exception to the custom or the android crash handler (I tested it, if a crash occurs there, then the crash handler does not work, if a crash happens in a coroutine, then it is correctly handled). I'm sorry, but the only thing you can do is to wait for the release of the new IndexHandler.

[Pazuu]

I am absolutely happy to wait and i really appreciate the work that is done here! Thank you for looking in to this!! :)

[Newar417]

Same here, as above. Additionally the "Show device ID", also stays blank (just circling until crash).

0.3.5 from FDroid, Asus Z00A, Lineage OS 7.1.2

[l-jonas]

@Newar417

Additionally the "Show device ID", also stays blank (just circling until crash).

Which above (there are different described situations)? Did you add an device already or did you not add one? Can you provide a crash report (eventually the crash handler from the settings of the App itself works for you; otherwise: "adb logcat" should work always)?

[Newar417]

As in the first post. I have had a device added already. Two now in the meanwhile. The in-built crash reporter does not work for me.

I hope this helps:

@Newar417 Yes, it helps. I created #106 for the first exception in it. The second exception (java.lang.IllegalArgumentException: provided path is invalid) is not usable yet. With the new version 0.3.6, there is a setting for detailed errors which - when enabled - should include the file name of the file which causes this exception.

(And the crash reporter should work for the second exception in the new version)

[Pazuu]

With version 0.3.7 i can add a device and establish a connection. The crash is gone and the device shows up in the list. Thanks!!! 😺

[l-jonas]

@yeus Does it work for you too now?
@Newar417 If you still get "provided path is invalid" then please enable the detailed errors and create a new issue.

[Newar417]

F-Droid only updated to 0.3.7 yesterday.
I can see my device ID, devices, folders, but not files. It still crashes after a little while. The basic crash reporter also works now, the below is from the clipboard. As you can see it is still there, will create the issue:
