| Summary | 0012301: MMA crashes when playing UPnP and WiFi connection is lost | ||||
| Description | Tested build 331 as follows: 1 play tracks via UPnP 2 put device into airplane mode --> currently playing track finishes playing --> MMA attempts to play multiple other inacessible tracks over UPnP --> MMA crashes Debug logs automatically sent by my account at 2014/11/06 10:50am EST. Note: attempting the same test on other occasions yielded different results: - In one case audio stopped playing, but the seekbar and timer continued to advance until the track was over. - A user reported another outcome in which the first track stopped, and then the next track (which was also inaccessible) started playing a few seconds which were presumably loaded in the buffer. Proposed fixes: a) If network playback is occurring and an external action triggers the network to go down, then we can use a variant of the following dialog that appears when the user attempts to browse UPnP while Wi-Fi is disabled: Wi-Fi disabled --------------- [Cancel] [Ignore] [Enable] The modified version could be something like: ------------------------------------- Wi-Fi disabled <countdown timer 30s> ------------------------------------- Playback has been interrupted due to network problems. ------------------------------------- [Cancel] [Ignore] [Re-enable] [Always Re-enable] ------------------------------------- b) After the countdown timer has expired, if the network does goes down while playback over UPnP is active, then playback should advance to the next track on the NP list that is local, and if none are it should stop. | ||||

Per discussion with Marek, the issue would be better resolved without user interaction. i.e.: -ensure that the Wi-Fi connection is maintained active when playing over UPnP (to what extent though? i.e. what if the user activates airplane mode?) as other UPnP apps do. -fail gracefully in the event that a wi-fi connection is lost (i.e. give a single toast message and proceed to the next accessible track, rather than crashing and/or resetting the playback pointer to the first track in the list). Toast messages discussed in related bugs: Skipping inaccessible tracks Skipping tracks (missing codec) |

- I meant that we should assure that wifi lock is held and wifi won't be turned off by system (to spare resources) not by user. - as discussed, MMA should check all tracks and then jump back to track that was last valid. This will be fixed as part of 0010826 because it is the same behaviour as for unsupported or invalid tracks |

According to mcow, the wifi connection still goes down sometimes during playback. See debug log AZ3SRGR7YI and report at: http://www.mediamonkey.com/forum/viewtopic.php?f=21&t=78308#p400306 |

I'm not sure if the last fix works or not, but there's a regression in build 364--MMA now crashes if Wi-Fi becomes unavailable (tested by turning off Wi-Fi while MMA is playing). This had previously been fixed. Edit: this crash occurs in both build 363, 364, and 365. I've created a log of this with build 365 so that you can compare whether it's the same issue as 0012480: Played NP list consisting of UPnP Tracks: 'Owner of a Lonely Heart' 'Venus' 'Walk Like an Egyptia' While 'Owner of a Lonely Heart' was playing, turn off Wi-Fi. --> MMA crashes when 'Venus' completes and 'Walk like an Egyptian' is about to play.

There are some exceptions caused by connection lost but it looks like the crash was caused by loading of artwork for remote players. This should be fixed as part of 0012201 by replacing direct bitmap loader by Universal Image Loader Now I have added catching of exception. So it shouldn't crash. |
