The docs say "The onStart() and onStop() methods can be called multiple times, as the activity alternates between being visible and hidden to the user"When I press the back button an it will go back to the previous activity which totally covers the old one.What is going on here?

Each time I switch the orientation of the device, onStop() and onDestroy() are called. They are also called when I close the Avtivity (dismiss()), and when I press 'back' key. In onStop() or onDestroy() methods : how can I know how I can here ? I'd like to run some code when I close the Activity (back button), but not if I change screen orientation

i have an app that haves a lot of activitys, all created with ONACTIVITYRESULT.which method is called when i press back key? i need to know it because i have to override/implement code on it
View 2 Replies View RelatedI need be able to tell if Activity.onStop() was called because my application is moving to a new activity, or if it was closed because the user pressed the "Home" key or hit the back button from the bottom of the activity stack.The reason is because I need to know when it is appropriate to shut off music that is playing in my application (A game). There is nothing more annoying than hitting home and having something playing music in the background.However, Activity.OnStop() is called for each activity change, and I don't want to suspend music when moving between multiple activities in my app. I just can't find a way to differentiate between going home and going to a internal activity.Am I perhaps hooking into the wrong events?

View 6 Replies View RelatedI'm saving the state of my activities for orientation change support, it works well. Sometimes I have a dialog open though and need to save its state as well. My dialog's onStop() method doesn't seem to get called when I change orientation. Where would get notified inside the Dialog that we're being destroyed, so I can save its state?
View 3 Replies View RelatedI have a problem with the activity lifecycle specifically on Nexus One (2.1 running on emulator works fine). If I just create a simple empty Activity with no special launchModes that logs the calls on the onStart and onStop methods, this is what I see: - launch app: onStart called; - home button: onStop NOT called; - launch app: onStart NOT called; - home button: onStop NOT called: and so on. Sometimes if I press the back button then the onStop is not called, but the when i launch the activity again the onStart is called and right after the onStop is called. Similar results with different launchModes. What is going on? Can anyone confirm this?

View 5 Replies View RelatedMy application uses GPS updates while it is running and I would like that to stop when the user back out of the app as I assume it will continue wasting a lot of battery power. I've tried intercepting the back button press but it doesn't seem to work. I'm not sure if this is because it's not executing the code or I'm using the wrong command.

Whenever I am using any app and press the home button, the home screen blacks out for a few secs and it takes around 10 sec to get all the icons back and before I can start using my phone again. I am using a non rooted mytouch 3g.
This problem does not happen if I exit an app by pressing the back button. It becomes very annoying at times.
So i rooted with Droid Does rom, because i heard its nice and fast and what not. So basically the only problem i have with it is this.
When on a call, the proximity sensor doesnt work, so the screen goes black. And when i press the end call button to turn the screen back on it just ends the call. Is this normal? Or a known issue?

View 3 Replies View RelatedThis is my first android device and i'm loving it... but one thing that irks me is the use, or lack thereof, of the back button.
As I am navigating menus and options in the Settings, I cannot simply go back one menu using the back key. For example, if I go to Settings->Battery Manager->Battery Profile Options and want to go back to the Settings screen, I cannot.
Pushing the back button does nothing and I can only go back to the Settings menu by going Home, then re-entering.
Another quirk regarding the back button is when reading emails. Using a regular email account such as Hotmail, I cannot simply read an email and go back to the inbox using the button.
It makes navigating the phone very tedious.
I am trying to catch when the user has pressed the Home button. I thought I could use
protected void onResume()
{
registerReceiver(homeReceiver, new IntentFilter(Intent.CATEGORY_HOME));
}
...
private BroadcastReceiver homeReceiver = new BroadcastReceiver()
{
public void onReceive(Context context, Intent intent)
{
// logic here
}
};
but that doesn't seem to work. I understand that onPause will be called, but my particular app has some logic that I need to handle separately. Short story is based on some info coming in, the app will display new Activities to the user. To prevent Back button issues, as each Activity hits it's onStop it calls finish on itself. However if the user presses the Home button I do not want the Activity to call finish so that when the user presses the app icon on the home screen or via the Recently run apps list, the last Activity is brought back
I realize the Camera button on the Droid X is not a standard feature across all phones, so, I'm curious how to attach a callback to it. I have a camera application that I wrote and I want the user to be able to snap the picture by pressing that button, but currently it doesn't work that way, so, I'm wondering how to attach my callback to it.

View 2 Replies View RelatedHow can I capture a long press of the device menu button in my application?I thought of an intent filter, but there's only an action called android.intent.action.SEARCH_LONG_PRESS, but nothing for the MENU button.I found that long press of the menu button actually does different things on different devices,i.e. on Nexus One it will show the soft keyboard, while on Samsung Galaxy S it will pop up the search widget.
View 5 Replies View RelatedI have an Activity with an EditText, a button and a ListView. The purpose is to type a search screen in the EditText, press the button and have the search results populate this list. This is all working perfectly, but the virtual keyboard is behaving strange. If I click the EditText, I get the virtual keyboard. If I click the "Done" button on the virtual keyboard, it goes away. However, if I click my search button before clicking "Done" on the virtual keyboard, the virtual keyboard stays and I can't get rid of it. Clicking the "Done" button does not close the keyboard. It changes the "Done" button from "Done" to an arrow and remains visible.
