Android :: Multiple Back Button Clicks Needed To Exit Application

Jul 30, 2010

In my current application design, I have an activity class application.java (which starts on launching the application), and it does not have a layout(UI screen). I call another class called servicebind.java from the onCreate method of my 1st class. here I bind to the local server (bindServer()). i call back the application class through an intent. Once I am back to my application class, I call my activity class called welcome.java which has a layout/UI. When I run this application, I am able to see the welcome screen. But the problem is, when I click on the back button, I get a black screen with just the title on top. I have to hit back button 3 times to exit the application.

The reason I see from the logs is that, the 1st 2 activity classes (application.java and services.java) does not get destroyed unless I hit the back button. So the 1st time I hit back button, the welcome activity gets destroyed. the next back button destroys the servicebind class and final back destroys the application class. Is the reason because these classes dont have a UI to display in the onCreate method. I do not want to change my design where I bind the service in the servicebind class and call the welcome activity in the application class.

Android :: Where The Quit / Exit Button?

Oct 28, 2010

I just used some great app and now I'm done, and... I want to *exit* the app. So I look for the 'exit' button.'quit' button.. nope can't find it.. !? Is there really no 'quit' button for android apps? (like in all other operating systems: the X button at the top right corner of the window) Shurely this can't be true. Only way to quit is to go to the home menu and start up a 2nd application dedicated to killing other apps and then kill app nr 1 from that?? Like buying a car that only has an 'on' switch and when i arrive at my destination, I have to open the hood and disconnect a gas lead or sometning to stop the engine.. (Or press the back button 10 times go through all documents you viewed until you reach the home screen). Isn't this like one of the basic features an OS should provide in its user interface?

HTC Incredible :: Why Droid Applications Don't All Come With Exit Button

Aug 5, 2010

why droid apps don't all come with an exit button. I know you can use the back button to eventually close a program but in so many cases that can mean several taps and in the case of a browser, going back several pages. Using the home button just leave the program running and using resources. It just seems like such an obvious oversight.

Android :: Button Doesn't Close / Exit On Application?

Nov 24, 2010

the problem is that this button doesn't exit of my app... it simply closes the current intent ant returns to the previous intent (window) of my app.... how i can do a real exit/close button? i tryed with this:

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

but it doesn't works, because when i turn back into my app, the app comes in the last opened window, and not in the first window of the app, how i can do that? i need that when i re-open my app it starts on the first window of my app

Android :: Exit Current Activity To Homescreen (without Using Home Button)?

May 3, 2010

What I am trying to do is emulating the "Home" button which takes one back to Android's homescreen. So here is what causes me problems: I have 3 launcher activities. The first one (which is connected to the homescreen icon) is just a (password protected) configuration activity. It will not be used by the user (just admin) One of the other 2 (both accessed via an app widget) is a questionnaire app. I'm allowing to jump back between questions via the Back button or a GUI back button as well. When the questionnaire is finished I sum up the answers given and provide a "Finish" button which should take the user back to the home screen.

For the questionnaire app I use a single activity (called ItemActivity) which calls itself (is that recursion as well when using intents?) to jump from one question to another:

Questionnaire.serializeToXML();
Intent i = new Intent().setClass(c, ItemActivity.class);
if(Questionnaire.instance.getCurrentItemNo() == Questionnaire.instance.getAmountOfItems()) {
Questionnaire.instance.setCompleted(true);
} else Questionnaire.instance.nextItem();
startActivity(i);

The final screen shows something like "Thank you for participating" as well as the formerly described button which should take one back to the homescreen. But I don't really get how to exit the Activity properly. I've e.g. used this.finish(); but this strangely brings up the "Thank you" screen again. So how can I just exit by jumping back to the homescreen?

Motorola Droid X : Back Button Functionality - Cannot Simply Go Back One Menu Using The Back Key

Jul 15, 2010

This 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.

Android :: How To Control Activity Flow - Back Button Versus Home Button

Sep 2, 2010

I have 3 activities in my app: Activity1 -> Activity2 -> Activity3. Inside Activity3, if the user presses Back, I would like to return to Activity2. In Activity3's onPause event, I added a finish() statement. That's probably not even necessary, but I wanted to make sure this Activity gets cleaned up. This works fine.
However, while in Activity3, if the user presses Home or starts a new app (through notification bar or some other means), I want both Activity3 and Activity2 to finish. If the user returns to this app, he should resume with Activity1.

I have figured out how to do one or the other, but I can't figure out how to handle both cases, if it's even possible. Can I trap the "Back" button in Activity3 and send a message back to Activity2 telling it not to finish()? It seems like the Activities follow the same lifecycle flow (Pause, Stop) regardless of what you do to send them to the background. Just to answer the question of why I want this behavior, imagine that Activity1 is a login screen, Activity2 is a selection screen, and Activity3 is a content screen. If I press Back from the content page, I want to be able to make a new selection. If I exit via any other means (Home, notification bar), I want the user to be "logged out".

Android :: WebView.clearHistory() - Don't Want Back Button To Allow User To Go Back Further Than Current Session

Mar 31, 2009

I call WebView.clearHistory(), but I am still able to go back after doing so. I want to reuse a WebView, but I don't want the back button to allow the user to go back further than the current "session" of using the WebView. Anybody know what is the best way to handle this? I thought for sure that clearHistory() would do it.

Android : Back Button - Disable In Buffering Or Should Prevent The Player Tostart If Back Is Clicked

Oct 11, 2010

In my android application i have a video list screen,a buffering screen and a videoplayer screen.
As soon as the user clicks an item from videolist screen ,he is navigated to buffering screen and then to videoplayer.
In the buffering screen i am using Async task and doing the loading process in on background process.

Now my issue is like the user if has selested a video then gets navigated to buffering screen.But if the user clicks back when he is in buffering screen then initially he is getting navigated to videolist screen but immediately after that again he is navigated to videoplayer screen.

What i would like to have is either the back button should be made disable in buffering or should prevent the player tostart if back is clicked.

Motorola Droid X : Back Button - Swipe Left To Right On Maybe The Top Bar It Goes Back

Jul 19, 2010

I'm finding that I'm using the back button A LOT whether browsing the web or just navigating the OS. It kind of sucks because the buttons on the droid x are well, really small, and sometimes hard to press because they are so narrow and flimsy feeling. And depending on how you are holding the phone, it could be a good bit of distance for your thumb to travel or I'm finding myself having to reposition the phone in my hands just to reach the back button, which you seem to need very frequently.

Anyone know of any kind of back 'swipe' implementation ? Like some software you can install that makes it if you swipe left to right on maybe the top bar it goes back?

Android :: Android Application Have Exit Button (or Menu Function) Or Not?

Jan 27, 2009

should an Android application have an exit button (or menu function) or not? Ok, if there's some service or other resources consuming something running in the background I think the user should have an option to make it stop. But what about an application that would just sit there, inactive? If I take a look at the standard application it seems that the Android philosophy is to keep the applications running and let the system decide when to stop and destroy an application idling in the background. I didn't recognize "exit" or "quit" options in the standard programs. On the other hand - why not let the user decide and give the option to quit some software if he knows it's currently not used. So, what's the advice here? Give even a "passive" application an exit button? Or not and just leave it to the system?

HTC Incredible :: Swiping Down Notification Bar / Back It Up - Hit Back Button?

Instead of trying to grab the notification bar and swiping it down, simply start ABOVE the screen and swipe down. Fast or slow makes no difference.

You can swipe it back up, or simply hit the back button.

Android :: Android - Override Back Button To Act Like Home Button

Jan 4, 2010

On pressing the back button, I'd like my application to go into the stopped state, rather than the destroyed state. In the Android docs it states: not all activities have the behavior that they are destroyed when BACK is pressed. When the user starts playing music in the Music application and then presses BACK, the application overrides the normal back behavior, preventing the player activity from being destroyed, and continues playing music, even though its activity is no longer visible


How do I replicate this functionality in my own application? I think there must be three possibilities.

1) Capture the back button press (as below) and then call whatever method(s) the home button calls...........

HTC EVO 4G :: Back Button Not Responsive / Way To Fix?

Sorry if someone else has posted this, but I searched and didn't find anything. I've noticed that since I updated a few days ago, my back button has become pretty useless. I have to tap it several times before it will go back a screen. I know I'm hitting the button right... there is still haptic feedback, just nothing happens on the screen.

HTC EVO 4G :: Home Button - Takes Back

Aug 3, 2010

As an avid user of ADW and Launcherpro, I encountered some problems after the update to 2.2. For instance, If I switch to LauncherPro, and set it as default via "Home Switcher", the next time I hit the home button it still takes me back to Sense. The solution I found is this:

1. You cannot use Home Swithcer.
2. After uninstalling Home Switcher, go to Settings> Applications> Manage Applications.
3. Click the tab to show all, navigate to "HTC Sense", clear it's defaults.
4. Now, the next time you hit Home, it will ask what to do. Select the launcher of your choice and make it default.

From here out, you can use Home Switcher to launch a different launcher, but know that the "Set Default" action will not work for 2.2. You will have to clear default for whatever launcher in order for home to function properly for whatever launcher you choose.

Android :: Back Vs Home Button

Jul 4, 2010

This has been brought up before, but I was unable to find a satisfying answer. And I know it's a newbish question.

What is the difference between exiting an app with the back button compared to the home button? I am not talking about switching to the home screen, I am talking about a scenario when you want to exit an app. For example, you play a game, you're done - do you press home or back? Or, you're in the Facebook app and you want to exit to the homescreen - what do you press - back or home? At first, I thought both buttons do the same with the difference that home brings you to the homescreen instantly while back goes through your previous steps/pages/screens in the current app and then returns you the homescreen.

But later I noticed that 'reactivating' some apps that were exited via the back button cause them to 'reload' (the loading screen shows up - with certain games, grooveshark's loading screen, etc.) while they switch back instantly when "exited" with the home button.

I gather the way to 'leave' an app you don't plan on using for at least a short while (I am not talking about closing the app, I know it's up to Android, or some task-killer) is the back button, while home is more for task switching/starting new apps while old ones are running.

Is there any kind of skin to put on top of this until that would make these buttons available when I actually need to press them? Or is there some setting in the menus to disable them, or configure them?

Android :: Control Back Button

Aug 12, 2009

I want to get the Text data value from Sub-Activity back. And everything is ok. But when the Sub-activity was opened, then I just click back "button" on the phone, it throw an exception error. I found on the android NotePad life-cycle control toturial but It's hard to understand. Can someone help me? This is my code:
