So how to achieve that?
View 5 Replies View RelatedI want dont want the activity animation that comes by default when we start a new activity (i.e. the right to left scrolling effect to new activity view) so i googled a bit and found a flag FLAG_ACTIVITY_NO_ANIMATION in the Intent class also i applied that flag to my intent via the setflags() method but somehow i still see the activity animation when a new actvity is launced ( i am developing in android 2.1 update).
View 6 Replies View RelatedMy problem is: Activity A called Activity B, and in Activity B, it start a background thread to do some client-server work. But it maybe takes too much time. So i add a cancel button to call the stop() method to stop the thread, and call finish() to finish the Activity B and go back to Activity A. Although it is back to Activity A, the thread isn't stop immediately. Can i just call the finish() to go back to Activity A, and leave the thread to exit by itself? If it is not the right way, which is?

View 2 Replies View RelatedI have a START and STOP button in the main screen of an App. there are some GUI and threads that are instantiated when I click on START. When I click on stop, I want everything to be stopped and the activity should come back to its origin state. To the state that is exactly same like when launched (when we tapped on App icon in mobile).Is it possible to do this? I tried with finish() , this killed the app and exited . I don't want to exit from main screen. rather, on clicking STOP I want app to come back to origin or born state.

Currently working on a simple app to allow users to find various things around them. When the activity that shows the Google map is active I can see the GPS icon on the status bar, which is normal. But I need to be able to stop the GPS hardware when my user navigates away from the activity, and switch the GPS back on when the activity is shown.
Is there a simple way to stop GPS when a user navigate away from an activity? I have tried the LocationManager's removeUpdates() but this doesn't actually stop the GPS (the icon is still flashing on the status bar and draining the battery).
What I'm looking for is a simple way to programatically stop the GPS hardware.
Can anyone tell me how to stop media player that was started in a previous activity?For ex. In activity-1 button pressed that did - mp.start(); then activity-2 starts for different layout with new buttons, then when button pressed, mp.stop is called, but does not stop the media from the first activity.
View 4 Replies View RelatedI have an AsyncTask object which starts executing when the activity is created and does stuff in the background (downloads upto 100 images). Everything works fine but there is this peculiar behavior which i'm not able to understand.For eg: when the android screen's orientation changes then the activity is destroyed and created again. So I override the onRetainNonConfigurationInstance() method and save all the downloaded data executed in the AsyncTask. My purpose of doing this is to not have AsyncTask run each time activity is destroyed-created during orientation changes, but as i can see in my logs the previous AsynTask is still executing. (The data is saved correctly though)I even tried to cancel the AsynTask in the onDestroy() method of the activity but the logs still show AsynTask as running.This is really strange behavior and would really be thankful if someone can tell me the correct procedure to stop/cancel the AsynTask.
View 1 Replies View RelatedI have an application that must create a database and if that fails, then no sense moving forward. I've built an AlertDialog and show() it but it never displays. The logic falls through and then barfs because of the missing database.What is the right/best way to throw up a message and halt the activity? The code below executes fine (meaning the show() occurs while debugging and it falls to the next line) but the UI never displays this alert.BTW I realize the throw might not be the most graceful but I'm not even getting that far so.
View 2 Replies View RelatedIn Android, I have some code to check whether the user has GPS switched on, and launch the Settings for them to turn it on if they don't.However, I'm finding that if the user opens the Settings, turns GPS on, then carries on using the app as normal, there is an odd problem. Often, when the user reopens the app, the Settings are at the front. How can I set them so they don't keep reappearing?I wonder if I should be using the CLEAR_TOP flag or something similar.I've tried looking at the docs for the Activity flags but find them a bit confusing.
View 1 Replies View RelatedI have started dialer activity with code
Intent myIntent = new Intent(Intent.ACTION_CALL, Uri.parse(createTelUrl("1234567"))); startActivityForResult(myIntent);
Is there a way to stop the dialer activity from same code.? Logically it should be possible as i started it and i should have rights to stop it as well.
I have a Timer which executes a TimerTask every 30 seconds. I only want the timer to launch a new TimerTask if the Activity is displayed i.e. if the user receives a phone call or launches a new activity the Timer will stop. I then need the Timer to restart when the Activity is re-launched and comes into focus.
Now this should be easy, I override the "onWindowFocusChanged(boolean hasFocus)" method and either start or stop the timer depending on the value of has Focus. The way I start the timer is to create a new Timer object and TimerTask each time and the way I stop the Timer is to call the cancel() method on the Timer object and set timer to null.
My problem is this doesn't always work, if I launch the activity which has the Timer and switch orientations quickly (to start/stop the Activity) I find the Timer is not always canceled and I end up with multiple Timers launching TimerTasks at an ever increasing rate.
Just like the title says, Is there a simple line of code I could add to onStop()that will simply stop any gps activity currently going on with my application?

View 1 Replies View RelatedThis 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.
View 2 Replies View RelatedI 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();..........................
In my application i have several activities and i want to start background music whenever my *Application* is launched and stop music whenever *Application* is paused or stopped.
View 4 Replies View RelatedOkay when user presses log out button what's supposed to happen is:
Code:
stopService(myIntent);
unbindService(mConnection);
mIsBound = false;
I need to shut down the service on background.Except the service restarts itself over and over again! Even if I kill the program from task manager the service restarts itself. Other programs aren't using the service. when I uninstalled the program the foreground program information popped up indicating it was STILL there(albeit this I solved by rebooting phone).
When user says he's finished with the program 'least he can expect is for the program to stay down rather than keep eating battery by acquiring GPS signal and sending them to server. The program is not intended to be "once you log in you need to Uninstall me and reboot phone to get rid of me!" type of program!
I have a very simple app. I have simplified for sake of discussion, but I think this is a good representation.
My issue is that when I exit the app, the GPS continues receive updates. As far as I can tell the app never stops running, it just no longer displays the map activity.
I have to be missing something important.
CODE:..............
Whenever the memory needs to be reclaimed, the process is being killed by Activity Manager Service in killPidsForProcess. I have a back button in my activity window on right corner of the title bar.
I want to kill the activity completely on clicking the close button. Can I reuse the same function and will it have any major effect? Please help me out in this.
I want to be able to show the Battery Info activity in my app, which shows things such as the exact level, battery health, etc.I'm not sure how I can get it, though a few applications such as Power Manager, Any Cut, etc. show this screen as well. I found in the source code of Settings this intent in a file called testing_settings.xml,But I don't know how to use it. I would guess from the fact that Any Cut has a list of activities, that a list of said activities exists somewhere, and therefore an easy way to access them exists, but I haven't found it.
