Crashing with my lms server

[ohuc]

Crashing constanly

[maniac103]

What version of the app - built from git or F-Droid? Did you try restarting the server? What server version?

[maniac103]

And most importantly: can you provide output of adb logcat?

[ohuc]

Running the F-Droid Build
Not sure about the server version this is how it's running

Also, I'm trying to connect to a music assistant client which connects perfectly when I use the squeezer app.

Here are the logs

Also I'm trying to just get the controls of the Music assistant server in my mobile phone which the squeezer app could do but it has a lot of delay issues

I've been looking for an android client for Music Assistant also. I don't have a LMS up currently, does this act as a client/endpoint for any slim protocol/squeezelite server, or is it perhaps a wrapper around a LMS server's web interface? I'm currently sharing files to MA from a NAS.

Well i just enabled the "Slimproto (Squeezebox players)"
as one of the player providers and used the music assistant companion app for windows to emulate it as a speaker, however now while trying to connect to the server with squeeze client it crashes

So I think the music assistant server acts as a LMS server itself

[maniac103]

This app interacts as client to LMS' cometd server interface.
From the log it looks like MA's implementation just doesn't provide media directories, which are used only for reconstructing the folder structure during music download, so I guess I can make those optional.
I want to make one thing clear though: if MA differs more significantly from LMS than in such minor details, I don't have any intentions to support it, for two reasons:

• I don't have any way (or rather: intentions) to test it because I don't use MA myself
• The logic behind the data decoding is complicated enough as is already, I don't want to make it even more complicated for supporting a server that never was intended to be supported.

I hope for your understanding there ;-)

I'll provide a test APK for making mediadirs optional, we'll see where this goes.

[ohuc]

I don't think it differs too much because it seems to be running all good in the squeezer app except for the fact that there is a bit of a delay

Alright waiting for the APK

[droyholmes]

I appreciate you taking the time to even make a test APK. I totally understand the complications as well as your limited time. Good luck on this project either way!

[maniac103]

Test APK (rename to .apk)

(File is just named .zip due to Github's file name restrictions)

This makes mediadirs optional, which in turn renders the download folder structure option 'match server' useless. If all goes well, I'll improve things there to make that option become unavailable in that case.

Please let me know if this works for you, or - in case it doesn't - provide a new log.

Still crashing

[maniac103]

Stupid me ... note to self: don't do stuff in a hurry, it leads to mistakes :-(

Next attempt

[ohuc]

Thanks for the test apk :)
However it still seems to be crashing

I think it may be a lot different to the way lms works I guess because it seems to be crashing at every little minor detail

[maniac103]

One notable difference between Squeeze Client and Squeezer that was important to me is that I made the JSON consumer as rigid as possible to get a better understanding of what input data I can rely on and what data is optional. Squeezer is more lenient in that regard, at the expense of much more complicated code (because it needs special case handling for missing values everywhere).
However, in this particular case, it looks like the JSON is not actually valid?
Here's another APK, this time as debug version, which should dump the received data into logcat. The crash will be the same, but can you provide the data right before the crash from the log, please?

[ohuc]

sorry provided the same log earlier
Is this what you were looking for?
