| Summary: A few days ago, some Chromecast-supporting Android apps | |
| started crashing upon launch. Other Android apps, notably YouTube, | |
| remain unaffected, as do iOS apps and Chromecast support in Chrome | |
| (see table below). Today, I discovered that these crashes go away | |
| when I remove the SONOS BRIDGE device that connects my SONOS audio | |
| system to the same network. | |
| My hypothesis: There is some interaction between the Chromecast | |
| device-discovery logic and the SONOS bridge's presence on the network | |
| that causes the problem. The most likely explanation for why these | |
| problems only showed up recently and don't affect all apps is that | |
| they are caused by recent changes in the Chromecast libraries | |
| released for Android and shared by the affected apps. | |

| Notes: | |
| - The crashes occur shortly after app launch, apparently during | |
| Chromecast discovery, and occur if and only if the SONOS bridge is | |
| powered on *and* connected to the same network as the Chromecast | |
| device. In my case, the SONOS bridge is connected via Ethernet | |
| cable to the WiFi router that the Chromecast connects to via WiFi. | |
| - The crashes still occur when the Chromecast device is powered off. | |
