Bluedot android app crashes on first launch

[avipars]

Appears to be related to the android permissions model. After it crashed, i was able to reopen it and approve the Bluetooth permission (nearby devices) and it is fine

Device - galaxy s23 running android 14

Is the android app open sourced?

Is it possible to request adding a dark mode to the app (or can I make a pull request to do so)?

Its the first report I have had of it crashing on first open.

There was significant change made to the app for Android 12 (I think) when the permissions model changed.

I dont experience the same issue on my Android 14 device. If you can debug that would be useful.

The android client code is in this repo - https://github.com/martinohanlon/BlueDot/tree/master/clients/android

Cool!

As it was downloaded from google play (jan3rd 2023 update android12+ fixes), you may be able to see ANR and crash logs in the dashboard of the app. Additionally, I pasted the logcat below.

I cleared cache and app data first. Then, immediately after I try to open the app, it crashes and then the permission dialog for Nearby Devices pops up (Allow Blue Dot to find, connect to, and determine the relative position of nearby devices).

Upon allowing it and turning on BT, app appears to work fine... I haven't set up the bluedot library on my pi yet (so I will need to do further testing)

Would you be open to putting the android app in it's own repo and adding to fdroid? If not, would you be fine if I fork the repo to do so?
(And maybe add an optional dark theme)?

From comment #190 (comment) looks like FDroid is well setup for Android code being in a subdirectory so no need for a new repo. But maybe it is worth a quick readme update to make discovery easier.

Code fix available in (closed) PR #190 and fork/branch https://github.com/clach04/BlueDot/tree/issue_189_android_crash
