I've been making a simple android app here, but i'm stuck with a problem. The app is composed of 1 splash(that is the main activity) and 4 other activities(one of them is used to go to the other 3). Whenever i exit my application and resume it with the process manager, it opens the activity i stopped at. But, when i resume it by clicking on the icon, it goes back to the splash activity. Is there any way to make it always go to where i stopped? Any flag or something i can set on the manifest?
This is an Android bug. The standard behaviour is to return to your application (in the same state as when you left) when launching it from the HOME screen. However, if you started your application for the first time from the installer, this gets broken.
To check if you are seeing this behaviour, go to the Settings->Applications and force close your application. Now go to the HOME screen and start your application. Use your application for a bit. Now press the HOME button to return to the HOME screen and launch your application again by clicking on the icon. It should return to your application exactly the way you left it.
See https://stackoverflow.com/a/16447508/769265 for more information and other links to this long-standing and nasty Android bug.
When I build the application to the testing phone everything works fine. If i then press the home button go back to the main screen then run the app , again everything works fine.
However if I quit the app to the home screen then close the application from running in the background and then try to run the app again from the main icon, it wont run it just goes to black screen and stops the phone from working or itll load the main view and none of the buttons work.. the only way to fix the phone so its usable again is to lock it and turn the device on again..
has anyone suffered this same issue before?
Sometimes the bootstrap server seems to get confused when you hit the home button and return to the app. If you are testing multi-tasking/background behavior, try the following process:
Build and run from Xcode.
Disconnect your device (your app will quit).
Now, truly quit the app by double tapping the home button and holding down on the app icon.
Finally, reopen the app and test for multi-tasking/backgrounding behavior (your won't get console messages however).
In my appname-Info.plist
I have 'Application does not run in background' box checked.(it is ticked)
But when i press the button under the screen to close the app, and then double press the button it shows the list of apps and my app is there among the list of currently running apps. Does this mean that my app is running in the background?
If so is there a fix for this? I'd like to make sure my app is completely dead when user quits it.
Thanks

Your app is not running in the background after you close it.
Even if you see it in the switcher app list.
Application has different states
Active
InActive
Running in Background
Your application become in-active, not running in background.
Aplications are allaowd to run in the background only for:
Playing music.
Navigation needs.
VOIP (as Skype).
And you should explicitly ask the permission and set the appropriate code for doing that and not only check the 'Application does run in background' in the info.plist
The list you get when you double tap the home button is not a running applications list. That's a common misconception. It's actually a list of recently launched applications. Therefore it makes sense for your app to be in it even if it doesn't multitask.
What does double-tapping on the home button exactly do?
Does it list the applications running in background, OR
Does it list recently used applications?
I've implemented the "Application does not run in background" in my Info.plist file. In spite of this my application shows on double tapping the home button !! Yes I have tried a clean build.
It shows all recently-used apps, not just the multi-tasking ones. If you try to tap your app now, it will start exactly like it was first launched, displaying the launch image first before initializing (calling application:didFinishLaunchingWithOptions: and sending the relevant notifications).
Today i updated my 3GS i-phone to install my application to see it's functioning well in OS4,when i'm running the application and tap the home button it's goes to multitasking bar,then again i get the application from there it's goes to previous state where i was.i think the behavior is OK. but problem comes when i kill the application in multitasking bar and run it it's come to same state,simply it's ignore the login screen.
My question is when i kill the application i want to get my login screen, not the previous state, this application is working fine in 3GS,can some one please help me to fix this issue?
Thanks
Sam.
Sam,
If you don't want the OS to save state for you, you should place the key UIApplicationExitsOnSuspend in your info.plist file.
More information here: http://developer.apple.com/iphone/library/documentation/General/Reference/InfoPlistKeyReference/Articles/iPhoneOSKeys.html#//apple_ref/doc/uid/TP40009252-SW23
This will kill the app when the home button is pressed, instead of suspending it into the background (which is what iOS4 does for multi-tasking).
