TransactionTooLarge means that the data being sent through the IPC call is too large.
I just checked my test case and verified that this doesn't kill the service's process *if* it is in the foreground (with Service.startForeground()). I'm not sure what may be different in your situation... one thing to keep in mind is that when the user removes a task, and it is not safe to kill a process associated with it, then that process is marked as having a pending kill, and as soon as it becomes safe it will be killed. So for example at whatever point after that you are no longer foreground, your process will be killed. There was a change in JB to make this interaction better about finding processes associated with the app and killing them. If your service isn't running in the main process of the app, its process should always be killed now, where before it may not have been. However in all cases it is only killed if it is safe to do so -- that is if the process is at an oom_adj level that is safe to kill by the OOM killer. Just running a background service means it is safe to kill; the service itself will be restarted if you have indicated this is what you want. This is not a new situation that your app needs to deal with -- its process could always have been killed while in this state if memory was needed elsewhere (for example if the user launches a game that uses a lot of RAM). Back to the exception you mention, I wouldn't like to see this in the logs... if you can give me steps to reproduce it, it is something I would like to investigate. That said, your initial description is not actually a system problem as you describe it -- yes your process gets killed, but this is a normal part of operation you should be dealing with, and if you can't recover when it is restarted then that is something that needs to be fixed in the app. On Sat, Jul 21, 2012 at 4:01 PM, Andy dev <[email protected]> wrote: > Ok, I've found out a little more information.
