Hello, I've got an app that capture photos and video according to a schedule (for example, takes 6 photos at 10 second intervals, and then records 2 minutes of video, then repeats). This all seems to be fine, and when I leave it running it will continue for hours without any problem.
However, if I run it at the same time as another app (that runs as a Service, logging sensor information to SD card), the scheduled camera app will mysteriously crash at some point (anywhere between 10 mins and a couple of hours after it starts). The problem is always the same - a call of the stop() method of my MediaRecorder object never completes. In order to debug this, I created a wrapper class to MediaRecorder to log each call to any of the MediaRecorder methods, and so I can verify that the MediaRecorder object is always in the correct state when this crash occurs (ie. I'm not doing anything in the wrong order). At the point of the crash, the log message immediately before stop() is logged, but the one immediately afterwards isn't. Additionally, no exceptions are thrown, and logcat shows no error messages whatsoever. The crash only becomes evident when I press the UI and several seconds later an Application Not Responding dialog is shown (and the corresponding messages appear in logcat). >From looking at logcat, I wonder whether this could perhaps be some sort of memory problem - often before the failed call to stop(), I see a few Davlik garbage collector messages, but I didn't think they are normally cause for concern?

Can anyone suggest what might be happening, or how I could continue my investigations? Any help would be greatly appreciated.
