Android :: Stop Following Activity If Home Key Or Pressed Back Pressed
Jul 8, 2010
I have a problem and that is my SplashScreen I have. It is built as an intro and after 3 seconds it shows the main menu of the program. Anyway, if I press down Back or Home button during the time the SplashScreen shows, it closes, but the activity I have chosen to follow after the SplashScreen will still run after the three seconds.
My code: **UPDATED CODE**
Handler ur = new Handler();
myRun = new Runnable() {
public void run() {
mainIntent = new Intent(SplashScreen.this,MyApp.class);
SplashScreen.this.startActivity(mainIntent);
SplashScreen.this.finish();..........................

I saw another thread related to this question, but did not find the answer that was useful to me. Is it possible when the user presses the Home button to be able to finish() my activity somewhere? I saw that people were having problems with using onStop(). Has anyone found a resolution to see if this is always called on Home being pressed?

I am having an issue related to home key . when i press home key all current activity gets hidden. but when i press the executable it again starts from the fisrt screen . I have overidden all methods nsaveInstaceState opPause onStop onResume
but there are still issues what is the right way to handle those conditions. When i am pressing home button i am storing the widgets state in database and when i again click the exectable i am checking the database state and starting the new Intent as saved when user presses the home button .Is it the right way to do that as i am facing the problem when user does the same and again presses the back button , there is already on intent available in stack of activity .

I'm trying to do something which really ought to be quite easy, but it's driving me crazy. I'm trying to launch an activity when a home screen widget is pressed, such as a configuration activity for the widget. I think I've followed word for word the tutorial on the Android Developers website, and even a few unofficial tutorials as well, but I must be missing something important as it doesn't work.

like many others, I want to kill my Android application on "exit" button. Really kill, not just move to background and stop all active code. (I know very well that Android does not like it.) I found Process.killProcess(Process.myPid()); and System.exit(0) which both work fine (I have no problem with activity stack, the "exit" button is in my base Activity.). But there is a problem. When I kill my process and I am back in the shell, I press [Home] button. It shows list of applications that are on the background including my application which has been killed.
Is there a way how to do both: 1) kill the process and 2) remove it from the Android application list that is shown after user presses [Home] button? Thanks for all replays (with the exception of that stupid "you should not exit applications explicitly on Android"

I have a EditText filed in my Activity class, Where I need to retain data, when orientation is changed or "HOME" button is pressed or "BACK(FINISH)" is pressed. Android internally maintaining EditText when orientation is changed or HOME button is pressed. But it is not maintaining EditText status when BACK button is pressed. How can I make it happen to retain data in all three cases (orientation is changed, HOME is pressed, Back is pressed) in a feasible way?

While developing a sample android application I have constructed two activities
1)Activity 1
2)Activity 2
Now Activity 2 is the foreground activity whereas Activity 1 is the background one. Now user presses Home key. The application(i.e. both the activities) disappear. Now is we relaunch the application we see Activity 1 as the foreground activity. My question is:
1)Does the platform maintain any history entry when pressed home key?
2)How do we take the user to the last launch activity on relaunching the application?

I have an activity that contains several user editable items (an EditText field, RatingBar, etc). I'd like to prompt the user if the back/home button is pressed and changes have been made that have not yet been saved. After reading through the android documentation, it seems like this piece of code should go in the onPause method. I've tried putting an AlertDialog in the onPause however the dialog gets shown and then immediately tears down because nothing is there to block the pause from completing.

This is what I'm trying to support. Can this be done?
a) User is an Activity A in my app. b) The user is taken to the native dialer when he chooses a particular action in my Activity c) User presses the back key d) Taken to homescreen
Is there a way I can change it, so the back key press returns him to my app, instead of native homescreen?

In my android app I have a Tabhost with a ListView as one of the tabs. By clicking on an item in the ListView (an address) I start an Intent to Google Maps for directions and the choice dialog pops up for google maps, web browser etc. Problem is if I press the hard back button then the launch dialog goes away but also the ListView is cleared. Any idea why?

I did a halfa** search of jsut this fourm because I'm at work and it is the only one I can get to. I was wondering if any of the rooted Linix gurus around these parts knew of an easy set of commands I can type using ADB, or a quick patch that would return my phone to the home screen when end call is pressed. It is drivig me crazy. I know about the program NotCallLog, but before I install yet another program onto my baby.

I wanted to share that with you, because I'm sure I'm not the only one who has this problem. The trouble was that the back of my HTC Hero (white version) was creaking when it was pressed. That applies mostly to the area around the volume rocker. Obviously, the back cover is made from flexible plastic and it is not making very good contact with the phone itself - i.e. there is a slight distance between the back cover and the device. So what I did is to put some tape (regular transparent tape) on the back near the volume rocker opening at the hollow (which is supposed to be a space for the battery but it's leaving way too much empty space) and everything worked like a charm. I played with my phone for a week purposely seeking for the creaking sound but the method surprisingly gave very good results .
If you know a better way to fix the problem.

We are experiencing this strange problem. If I press screen off button When my activity is running, its again starting a new activity. If I press the screen off button again and unlock the phone, it again starts a new activity. So in total there are 2 new activities getting created for one screen off and on.

I have noticed while working in the emulator that whenever i get out of my app via any method other than pressing the back button, my toggle button (if pressed) will have its state saved and return to that state when i return to the app. im guessing its because its value gets saved in a bundle and reloaded when i return. when i leave the app via the back button, this does not happen and the toggle is always off when i return. is there any way to get the value of the toggle back if the user leaves via the back button, without having to save the value in a db table? alternatively, if my apps notification is in the status bar, i can be confident that the toggle should always be selected, so if there is no way to save the state, is there a way to find out if my apps notification is currently being displayed? then it would be easy to just set the toggle each time via a quick check of the status bar.

This is difficult for me to diagnose because the Log doesn't provide the offending code line that indicates what caused it.Running the app in the Emulator seems to work OK until I press Home or Back from the Main Activity. Using Back between the activities in the program seems to work OK, it only fails at the Main. I don't have the app finished yet so I haven't loaded it to a device yet.The Log says there was a null pointer exception so I would like to find why.The log points to the android routines (and I don't appear to have the source for those routines in the emulator-most but not all and these are refering to those I can't access). The log gives up at one point and says "11 more".It would be nice to see the remaining 11 in the hopes that one of them points to the line in my code that caused the offense.I'm looking for ideas on ways to find the error and hopefully cure it.

Does anyone know how to tell when the headset button is being pressed? I'd like to support the usb headsets and possibly bluetooth headsets. My app is a media player and ideally, I could register it somewhere so that if no app that uses the headset button has focus it button press would act as a play/pause command in my app. If the phone is ringing or a call is in progress, I'd like to be sensitive to that and let the button do what it normally does: pickup and hang up calls. we've been trying to chase the button down using this: Intent Filter headset Filter = new Intent Filter (Intent.ACTION_HEADSET_PLUG); headset Filter.addAction ("android.intent.action.HEADSET_STATE_CHANGED"); headsetFilter.addAction("android.bluetooth.intent.HEADSET_STATE"); headset Filter.addAction ("android.bluetooth.intent.HEADSET_STATE_CHANGED"); headset Filter.addAction ("android.bluetooth.intent.action.MODE_CHANGED"); headsetFilter.addAction("android.intent.action.MODE_CHANGED");

Is there a way I could get the color that is used when a button is pressed? I know that the button uses a default selector xml that consists of the pressed image. But, I am having some custom buttons for which I want it to be close to the default image used for pressed state.

There is know problem in all the Android phones. Go to Bluetooth Settings->Turn ON bluetooth->Click on bluetooth discovery->Then timer will start in summary->Long press on Bluetooth device discovery-> observe Bluetooth ON/OFF title start to toggle with Bluetooth Discovery toggle. I analyzed the issue. Blueooth ON/OFF is CheckBoxPreference. Bluetooth Discovery is also CheckBoxPreference which has dependency on Bluetooth ON/OFF. When we click on Bluetooth discovery then On thread will run at every second to update summary in Bluetooth Discovery preference. When we change the Bluetooth discovery to OFF then thread will be removed/ killed. When i press the Bluetooth discovery for long time when its already in ON State then still the thread will be updating the summary (remaining time from 120 to 00) till i press it. When i leave the Thread will stop. As it has dependency on Bluetooth ON/OFF, its making to the title invisible. But it should not happen. Solution: When i touch the Device Discovery i should kill the update summary thread then i guess, that problem will be solved. But in prefence i dont have any listener to know the pressed state. I hope somebody can give me solution.

i have an app widget that has a couple of buttons on it, and in my onUpdate() call, I am hooking up the buttons to do something when you press them
RemoteViews remoteViews = new RemoteViews(context.getPackageName (), R.layout.appwidget); remoteViews.setOnClickPendingIntent(R.id.Button1, button1PendingIntent); remoteViews.setOnClickPendingIntent(R.id.Button2, button2PendingIntent);
The problem is that when I click on button2, it sends the button1 pending intent. i think that's because it's reusing the pending intent. http://groups.google.com/group/android-developers/browse_thread/threa. "If the creating application later re-retrieves the same kind of PendingIntent (same operation, same Intent action, data, categories, and components, and same flags), it will receive a PendingIntent representing the same token if that is still valid, and can thus call cancel() to remove it." So then the question is, how do I communicate which button was pressed?

In my activity I respond to an onClick() by replacing the current view with a new one (setContentView()). For some reason when I do this and then go back to the original view later the button I originally pressed still looks like it is pressed. If you 'refresh' it somehow (e.g. scroll over it with the trackball) then it reverts to the unpressed state. It's as if the button doesn't get the 'touch-up' event. The weird thing is: This only happens on my T-Mobile Pulse (android 1.5). It doesn't happen on the emulator. I've tried calling invalidate()/postInvalidate() on the view when I show it but it doesn't have any effect.
