I notice that my application continues to run in the background after I hit the home or back button. I tried calling the finish() method and it still says its running. On another note, how do I setup the keyListener to respond to the user hitting the back or home button. I tried implementing OnKeyListener and using findViewById(R.Layout.main).setOnKeyListener(this) to call finish().
Just got the new Droid X. Coming from a windows mobile phone (which I hated) I have a question on the android OS. It seems that when you are done with an app you just have to hit the menu button again.. but this leaves it in memory running.. is there anyway to close the and and just leave it? I did download the Advanced app killer but that seems silly to have to pick from a list of what you want closed.. I see no way to just close the app you are in.. it should be a default option for every app.. I hope I am just not finding it.. and it is there somewhere..
In my application there is a button called Exit. when i click the button it should end the application. I trie with finish(). It is not working. It is closing only the current scrren. I need to close all the screens.
I have requirement that needs to save data to a file. During multiple Activitiy screens, I add different data to a list and finally when user is not using the app (means if user exits app by pressing "home" button or "call" button), just before exiting that app, i want to save that data of the list to a file.
coding before exiting activity screen is simple - by calling onDestory () method, but here I want not one activity but the application exit.
So my question is How do I write a code that will be executed just before application exits ? I tried created one class extends Application, and then I override onTerminate() method, but it's not get called when I exit ( pressing home button on device)
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
Is it possible to stop all started services when the user hits the Home Button? I use: startService(new Intent(ClassName.this, ClassName2.class)); stopService(new Intent(ClassName.this, ClassName2.class));
This means I will have to somehow add the 'stopService()' for 7+ of my app classes I've researched this topic and I think there's 'onTerminate' but still not sure how this should be implemented.
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.
I have a project that builds against Android v2.1 . I can run it fine on a phone running 1.5 but when I try to launch it with an emulator running 1.5, the emulator doesn't show up on the list of available AVDs. I have the <uses-sdk android:minSdkVersion="3"/> tag in my manifest but it doesn't make a difference.
Has anyone experienced the sudden exit from an application or browser? It happens intermittantly on my phone where it will suddenly exit out with a vibration or two and return to main page. This has happened infrequently but many times in the past couple weeks.
I use a file browser to locate the APK, it installs successful and I can run it OK (when clicking "run" after install completes) However, if I then exit the application, I'm unable to see a launcher for it on my apps menu (where I would expect it, like other apps I've created) At the moment, every time I want to run the app, I first have to re-install it so I can access it, surely there must be a better way?
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?
I have an issue with identifying return to application after it was left using Home click. The main purpose of this is to define when do I have to display to user Type Password dialog. So, let's imaging such workflow, User works in application and decides to see what's the weather tomorrow. The User clicks Home button and is transfered to desktop. Now he goes back to My application. At this point we have to verify that our User is still the right one User by proposing him to type password. How can I identify this condition here? (returning after leaving by Home click)
I'm not sure whether I need to add an exit button to my app. Is there any point to doing this? And if on exiting one activity or service is not .finish() or closed properly could this cause a lot of damage?
application exit handling. My application has multiple Activity say : - EntryAct, Act1, Act2 .... Act10. When user presses home key on any of these Activities, I need to do some flag setting. Handling home key in every application Activity is not possible! Can someone tell how this can be achieved?Can't change anything in OnPause,OnStop or OnDestory of all activities Act1.
My application is a trial version apk. Once the period is completed, can I initiate another application to be installed/downloaded from the android market ( purchasing process) which is a paid application using the current running trail application.
I want my app to kill a running app but i got the problem that since AP I 8 the method is deprecated and i need to use another function. So i want that if AP I level of the device is smaller than 8 it runs this Activity Manager a M = (Activity Manager) this.get System Service(ACTIVITY_SERVICE); a M.restart Package(package); And from 8 this But how do i accomplish this because using something like an if will make the compiler complain.
I understand when an activity closes, onDestroy() is called. But this is not done always right? Sometimes, onPause() is called. So suppose I want to clear some memory when an activity closes, where exactly do I do it? Since onDestory may not be called, I cannot keep it there either right? Elaborating: I have 2 activities A1 and A2. A1 is hsown in the startup of the app. A1 calls A2 later. Suppose I create a class object in onCreate() of Activity A1. This object must be deleted when the I exit the app, i.e when the app is no longer visible. Is the best place to do this onDestroy() or onStop() of A1? I guess onPause() may not be the right place, because onPause() will be called when A1 calls A2 and I dont want to delete the object then.
I need an Android application which should be able to fetch data from the web (maybe an .apk or a .jar) and launch "something" from it.
If it's a "trivial" class there's no problem at all. This is my Loader
The problem is that the code I want to execute looks very like an application, which should have a "simple" view and some interaction on it.
I'm not able to invoke the "onCreate" method of my downloaded class.
I guess I've three streets:
I look for a method which silently install the application and then runs it (is it possible?) I understand how to initialize a second "application" inside my own one (with its own R and all stuff) I write my master program to fetch data from the web and construct pages dinamically.
I develop[e a small program to play the video from localhost ... but that is not working its show like ... ActivityManager: Warning: Activity not started, its current task has been brought to the front this is the error message ....
I have made an app which have target sdk a 2.2 and min sdk version as 3.
