Crash when player service is being stopped in some cases (NullPointerException)

[InconsolableCellist]

Checklist

• I made sure that there are no existing issues - open or closed - which I could contribute my information to.
• I have read the FAQ and my problem isn't listed.
• I have taken the time to fill in all the required details. I understand that the bug report will be dismissed otherwise.
• This issue contains only one bug.
• I have read and understood the contribution guidelines.

Affected version

0.27.0

Steps to reproduce the bug

1. Begin playing a video
2. Switch from WiFi to 5G or vice versa. Wait a moment

Expected behavior

Video continues to play

Actual behavior

Video stops playing and NewPipe opens up (even when playing in the background) with the guru meditation screen.

I'll need to close and open the app to recover. Also sometimes my position in the video will be lost, so even going to it through the History tab won't allow me to resume where I left off. That makes it even more annoying.

Affected device model

Additional information

Phone: SM-F936U1
One UI 5.0
Android 13
Kernel Version: 5.10.81-android12-9-25407272-abF936U1UEU1BVKB

This is a de-Googled phone, so it doesn't run Google Play Services, which has been put to deep sleep via adb.

Maybe you can add a null check here:

NewPipe/app/src/main/java/org/schabi/newpipe/player/mediasession/MediaSessionPlayerUi.java

Line 215 in 879d7a2

sessionConnector.setCustomActionProviders(

private void updateMediaSessionActions() {
    if (sessionConnector == null) {
        // log...
        return;
    }

    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.TIRAMISU) {
        return;
    }

    // ...
}

Or maybe it's clear to you why

NewPipe/app/src/main/java/org/schabi/newpipe/player/mediasession/MediaSessionPlayerUi.java

Line 280 in 879d7a2

public void onMetadataChanged(@NonNull final StreamInfo info) {

can be called when init apparently wasn't called, or sessionConnector is somehow being unset?

This happens very often to me, basically whenever I leave the house while playing a video in the background, or entering.

[opusforlife2]

Is that the error you get each time? This looks like a duplicate of #10097, but your error is different,

[AudricV]

No, that's completely different and is very likely a 0.27.0 regression related to media notification actions changes.

I can reproduce this issue if a playback error occurs when playing a content in the main player (so it is closed due to the error), while the player service is being stopped.

[marek22k]

I got the same error, but in a different situation. I was watching a video and wanted to play another one. I clicked on the other one. Then the message appeared. After clicking away the error message, I had to restart NewPipe.

Feel free to hide my message if it's annoying. However, since there was the "Waiting for Author" tag for a short time, I thought I'd write my error message briefly too.

[dolmen]

See also #11066, #11061, #11065, #11068.

[pawlosck]

When it will be fixed? Since few days, my newpipe is completely unusable. Anybody know, where is problem?
I am using Android14.
