Crash on Pixel Watch 2 after selecting "Available Devices"

[mangoobyt]

Clicking on

I have the same issue.

To give some additional context: I could connect WearMouse with an already connected device (my phone) only once, but that was a one-off.
Now, even though my phone is "connected" in the watch settings, it is displayed as "disconnected" in wearmouse. Switching connection on-off, it is displayed as "connecting..." in the app, but without actually connecting. It goes to "disconnected" after a few seconds.
Re-installing the app didn't help either.

@ginkage For context, this issue seems to be happening on wearAuthn too
Theory 1:
it primarily happens on devices running windows (11). It seems like something in windows 11 is blocking the bluetooth connection (the pixelwatch 2 shows that it is not connected, but windows says its connected to the watch) This makes it that the connection never exists. Testing the same situation on debian shows no problem whatsoever.

Theory 2:
google broke the bluetooth api with the pixel watch 2 and devices dont always register a connection

Some related but vague reports:

There are two separate issues. Clicking on "Available Devices" is one, for which I've captured the stack trace:

I think I can fix that one.

For Windows 11, please file a separate one.

This log should contain connecting to a windows 11 device and pressing selecting these in the watchmouse app:
After pressing connect to device nothing works

@fmeum Im tagging you too as I noticed that wearauthn is having the same issue where the connection to a windows 11 device doesnt seem to work. Here is a log: https://diededrive.designedbydie.de/index.php/s/8EFJQZExzB4yMkL
(File was too big for github)

Welp, that bugreport only shows that I did things correctly, according to the documentation, yet the app is still crashing due to not having some permission (supposed to be BLUETOOTH_ADVERTISE, and the app asks for it on startup). Probably a bug with the device itself.

Could very well be a problem with wearOS 4.0, had a buddy on a galaxy watch on wearOS 4 try it out, which he had the same issue. Time to contact google haha

[ginkage]

The thing is, I have a Galaxy Watch with wearOS 4, and I don't have that issue...
Did you accept all the permissions at the app start? You can also try removing the app and installing it again, so that it definitely asks you for the missing permissions.

[Cyanogenbot]

yeah i accepted the permissions... Are you running win 11 too?

[Cyanogenbot]

Reinstalling didnt do the job either :?, I think its a pixelwatch 2 issue then, the setting pane doesnt ever show it as being connected either. I dont think it can finish the connection..

[Cyanogenbot]

@ginkage for context, when connecting the pixelwatch to an ipad, your app works perfectly other than the available devices button, so It must be on googles side

[ginkage]

Thank you for the information. As soon as I get a chance to get my hands on a Pixel Watch with Wear OS 4 (that might take a few days or a few weeks), I'll try to reproduce it and hopefully find a way around it.
I don't think it's a matter of what you're connecting to, be it an iPad or Windows 11: since it does connect fine with a device it's already paired to, the problem is clearly in the way the app is requesting the Bluetooth stack to enable its visibility to other devices when you tap the "Available Devices" button.
In theory (that is, according to the official documentation), it should be enough to have the BLUETOOTH_ADVERTISE run-time permission granted and accepted by the user to request the Bluetooth visibility from the OS. But, as the crash happens within the checkStartAnyActivityPermission method, I think the issue is that the Pixel Watch 2 System UI does not have android:exported="true" set on the activity that is resolved for that Intent, which would indeed be a bug on Google side (extra note: this does not happen on Samsung with Wear OS 4).
Again, I am following the documentation to the letter for this functionality, so there's little I can do but to escalate this matter back up to Google.

[Cyanogenbot]

In that case, there definitely seem to be multiple bugs on googles pixel watch stack, namely the connection to devices and the permissions as you said. lets hope that those will be fixed. The problem I was referring to is that the pixel watch can’t even pair properly to windows devices haha, already files a bug report through Google support on that but I doubt it will be read. Thank you for the effort on the other issues though, let’s hope we can get these devices supported :)

Same on my Pixel Watch 1.
It crashed if I searched for available devices.

[rodolforfq]

Happening on OnePlus Watch 2 as well.

If I accept the permission request and enable precise location, it just crashes/closes. If I limit it to approximate location instead, screen goes black instead of simply crashing back to the previous screen.

Happy to provide more info or perform tests, if it's any help.

[TheBarii]

I have a Oneplus Watch 2 as well! It is also happening for me and WowMouse is also not working either. This is an important app that'll help me with making my daily life better. Really is unfortunate.

Willing to help in any way, please ask away here.

[TheBarii]

I also cannot connect to any devices at all. Clicking "connect" simply does absolutely nothing.
Available devices causes a crash.

[Munka9]

Same issue for me (Pixel Watch 2), was this ever fixed/worked around?

[ginkage]

Let me unpack this a bit...

AndroidRuntime: java.lang.SecurityException: Permission Denial: starting Intent { act=android.bluetooth.adapter.action.REQUEST_DISCOVERABLE cmp=com.google.android.apps.wearable.settings/onnectivity.bluetooth.BluetoothRequestDiscoverableActivity } from ProcessRecord{6dd0129 12368:com.ginkage.wearmouse/u0a118} (pid=12368, uid=10118) requires android.permission.BLUETOOTH

My AndroidManifest has this:

<uses-permission android:name="android.permission.BLUETOOTH"
 android:maxSdkVersion="30" />

as, according to the documentation, requesting android.permission.BLUETOOTH permission for API above 30 is wrong, see https://developer.android.com/develop/connectivity/bluetooth/bt-permissions
So, on WearOS 4 this Intent (android.bluetooth.adapter.action.REQUEST_DISCOVERABLE) should check for a different permission, android.permission.BLUETOOTH_ADVERTISE instead of android.permission.BLUETOOTH: https://developer.android.com/reference/android/bluetooth/BluetoothAdapter#ACTION_REQUEST_DISCOVERABLE
Thus, the fix should be made on the OS side, specifically in the AndroidManifest of the Settings app, in com.google.android.apps.wearable.settings/onnectivity.bluetooth.BluetoothRequestDiscoverableActivity.
As @Cyanogenbot has correctly mentioned, the same issue was present in WearAuthn as well. So, I'm putting in a workaround: now I'll request android.permission.BLUETOOTH on all API versions (even though this is incorrect!).
The bug for this was filed at Google back in January, but you know them... Also, reportedly this issue was fixed in Wear OS 5.
I've staged an updated version for review, so fingers crossed, maybe it will go through shortly.

[ginkage]

If I'm reading it correctly, the update should be live (as of yesterday). Can anyone on the thread confirm if it works?

[rodolforfq]

I can confirm it's all working for me (OnePlus Watch 2). Thanks @ginkage ! 🥇

[ginkage]

Alright, sounds like we're out of the woods. Thanks everyone for your input and patience. I only wish Google could fix its bugs (reported back in January!) quicker, but oh well, at least we can work around it.
A PR with the workaround will be merged soon. Have a nice day everyone.

im sorry to say but the issue hasn't been fully fixed yet. In the Wear Mouse app, Whenever I click my PC's username from the Paired Devices list, and then click Connect, it does not seem to work at all and it does nothing.
Edit: I've reinstalled the app and it's stuck at "Connecting". Clicking my PC from the list again shows a Disconnect option instead.

While trying to connect from the Bluetooth settings on my oneplus watch 2, it says "Couldn't connect".
But on my PC it says the watch is: "Connected, mic"
An alternative to your app, WowMouse has this similar bluetooth connectivity issue with oneplus watch 2. Any suggestions? I'm using the Play Store version.

[rodolforfq]

I should have probably mentioned my tests were performed with a Macbook. Not Windows.

It shouldn't matter all that much but worth putting that out there since @TheBarii isn't having much luck with Windows.

[TheBarii]

I'd also like to mention that I'm not able to connect to my phone. From the devices list, it says it's Disconnected while it clearly is not. I fear it's something to do with the "Connected, mic" issue.

If there is any way for me to help, please let me know.

[Suranjandas7]

facing the same issue on oneplus watch 2r as well
