You can tell when this is happening when you see \"WINDEATH\" in the Android log. You can see the full log via the Android SDK's \"adb logcat\" command line tool.\r\n\r\nYou can see this happening with Google's apps as well. Tap on the Calendar app and then create/tap on an event to display an event activity window. Press the home button and go to a different app. And then switch back to the Calendar app. Notice that the Calendar app is restarting (you can see its splashscreen). You would also see that it was forced-quit by the Android OS in the background as well (WINDEATH in adb logcat). The difference here is that Google's app keeps track of the last state it was in so that it can restore its previous state.\r\n\r\nAlso, the Android OS can force-quit your app when it is running low on memory as well. This is likely to happen if your app consumes a lot of memory such as images.",

					"body": "It's not crashing on resume. It's being force quit in the background after switching apps. That's my point.\r\n\r\nFor example, try adding this code snippet to your app:\r\n\r\n{code:javascript}\r\nsetInterval(function() {\r\n\tTi.API.info(\"@@@ Timer elapsed. \" + (new Date()).toString());\r\n}, 1000);\r\n{code}\r\n\r\nThe above will log a message every 1 second, even while the app is in the background (this isn't iOS; your app doesn't really suspend). When switching to another app with this setting on (or if the device is running low on memory), your app can be force-quit by the OS. When this happens, you'll notice that the above stops logging a message every 1 second and the last logged message will be followed by another message such as...\r\n\r\n{code}\r\nActivityManager: Killing <YourProcessId>:<YourPackageName>\r\n{code}\r\n\r\n...along with a message like this...\r\n\r\n{code}\r\nWindowManager: WIN DEATH: Window{228b981 u0 <YourPackageName>/<YourPackageName>.<YourActivityName>}\r\n{code}\r\n\r\nYou can't catch this event.  This is like a Windows Ctrl+Alt+Delete equivalent that's happening to your app. And unfortunately, Android won't automatically restore the last state of your app. It's up to you keep track of where it was last left off.\r\n\r\nAlso, I don't think the \"IllegalArgumentException\" stack trace you gave us is related. We actually see this exception when launching an app from a \"cold start\" from Appcelerator Studio. And it's an exception from the OS, not the Titanium app. Note that there is no Titanium/Appcelerator related things in the stack trace (although I'd like to know what triggers this).",
