[android-developers] Re: How to close an activity when the user clicks on home button
it may be as simple as adding android:clearTaskOnLaunch=true in your Manifest under the main activity tag to re-initialize after returning to Home screen. intbt On Feb 20, 4:54 am, Mark Murphy mmur...@commonsware.com wrote: Achanta wrote: But since I started trying to log everything to see the activity life cycle, what I observed is that onStop method is not actually being called when I click on home button. :: blink, blink :: Its being called as soon as i open my app again, which is not how I wanted it to do.

[android-developers] Re: How to close an activity when the user clicks on home button
I just tried it on an app I'm working on (Android 2.1), and onStop() was called at the point I pressed the HOME button. I am using Android 1.6 as I need to support all the phones which are working on that version also. And in this version or atleast for my situation its not working so. Are you doing anything unusual in your manifest vis a via android:launchMode or similar settings? Yes I was using launchMode=singleTask. I actually wanted singleInstance but somehow Voice recognizer is giving a connection problem when I use singleInstance. So just to see if it is working in the way you suggested, I tried removing all the launchMode etc in manifest and just left the activity name and label. This time onStop method or the onRestart method are never ever called. But these are being called when I set finishTaskOnLaunch to true in the manifest. Thank you anyway for the help and the suggestions. I atleast got it to work to the most extent if not stopping the updates and the activity on clicking home button. The other thing is that I expected my stack to be as it is and as soon as I open my app after hitting on home button, the activity which I was previously in will be opened. But it restarted the app itself. This is what I observed in my app. Say I have a main activity A and another Activity B. I come to Activity B from Activity A. Then I click on home button. It closes the app but does not yet call onStop on B. Now I open my app and it now calls onStop on Activity B. It starts Activity A again.

[android-developers] Re: How to close an activity when the user clicks on home button
Thankyou, I needed finishTaskonLaunch as that is more suitable than clearTaskOnLaunch for my case as I need to close the activity itself which I am opening in a separate task.

[android-developers] Re: How to close an activity when the user clicks on home button
Thank you Mark, I do know that I can you onStop method as it is supposed to be called when ever something else comes on to the screen (in this case the home page). But my situation is a little more complicated than that. I have an address field and an option for gps[if its switched on]. But in the bottom portion of the screen I will be loading my results based on the location. Now since I have loaded the results using the onCreate, its doing so. So I changed it to do all those things in the onStart method so that the Activity life cycle goes on smoothly. Thanks for the suggestion because of which I went through my Activity's lifecycle to see how everything is going on. But since I started trying to log everything to see the activity life cycle, what I observed is that onStop method is not actually being called when I click on home button. Its being called as soon as i open my app again, which is not how I wanted it to do. The locationUpdates should stop the moment the user hits home button. The other thing is that I expected my stack to be as it is and as soon as I open my app after hitting on home button, the activity which I was previously in will be opened. But it restarted the app itself. This is what I observed in my app. Say I have a main activity A and another Activity B. I come to Activity B from Activity A. Then I click on home button. It closes the app but does not yet call onStop on B. Now I open my app and it now calls onStop on Activity B. It starts Activity A again. Now only when I click on button for activity B, it calls onRestart method on Activity B. So am I doing something wrong or is it supposed to work in that way or is it a bug?

Then stop location updates in onStop(). This will get invoked: -- when the user presses HOME -- when the user pressed BACK (en route to onDestroy()) -- when the user takes a phone call -- when the user responds to a notification that brings up an activity -- etc. The one thing you may want to do is handle configuration changes yourself, so you won't be called with onStop() when the user rotates the screen. I need to do this just in case any user while in that activity clicks on home button and changes the location settings. I'm not sure what the location settings are. If you mean they disable GPS, your LocationListener should be notified of that. -- Mark Murphy (a Commons Guy)http://commonsware.com|http://twitter.com/commonsguy Android Training in US: 26-30 April 2010:http://onlc.com -- You received this message because you are subscribed to the Google Groups Android Developers group.
