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'm new android and i want to know how to remove more than one activity from stack. We use finish() for closing particular activity but i wanna close more than one activity underneath it, at a time.

View 4 Replies View RelatedI'm opening an Activity using this:
startActivity(new Intent(Parent.this, Child.class)); And on the child, I have this code on the onCreate function (the if contains more than just true, of course): public void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState); if (true) { AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setPositiveButton("OK", null); builder.setTitle("Error"); builder.setMessage("Connection error, please try later.") .show(); finishActivity(0); return;}}
Why is the activity not closing? I get the alert box, but then I have to tap the "back" button to go back.
When i launch Activity A, the screen goes black, then dark-gray. Then A launches B, and the screen goes black and dark-gray again. Is there a way to set the default background color to black? Activity A has no screen, its just a stub that calls B.
View 4 Replies View RelatedI created an activity by using a layout written in a XML file. I would like, in response to some events, to change the content of this activity. I would like to show a VideoView over the content. In response to some other event, I may want to go back to the first content. Would it be possible to switch the content of the activity this way without running another activity (I have another technical difficult in doing that)? I tried using setContentView( videoView), and then switching back with setContentView(T.layout.main), but it seems that, when going back to the main layout, all my buttons and text boxes are created again as they were new. Would it be possible to go back to the last state of all the controls?

View 7 Replies View RelatedThere are apparently at least three different techniques for changing screen brightness in the Android OS. Two of them no longer work post-cupcake and the third accepted technique evidently has a bug. I would like to increase screen brightness at the start of a one-view activity then turn the brightness back to the user setting at the end of the activity. No buttons, no second view or second activity. Just a maxed brightness at start and a return to original brightness setting at the end of the activity. The examples of the current technique using WindowManager.LayoutParams that I have located range from 2 lines of code
WindowManager.LayoutParams lp = getWindow().getAttributes();
lp.screenBrightness = 100 / 100.0f;
getWindow().setAttributes(lp);
To several pages of source code and numerous activities. Is there a simple example of maxing the screen brightness at start that someone can provide a link to?
For a new update I am changing the start-up work flow for the application. Part of this is setting the "android.intent.category.LAUNCHER" from one activity to another in my manifest. When I run an update from what is on the market to what I download from my website the application starts in the Activity where it used to start before the update. When I un install the application and install it from the same package I got from my website it starts in the Activity where I have now specified it to start. Shorter version: Update fails to update launching activity, un install- reinstall does update the launching activity. Is this a known issue? Do I really need to add logic to correct for people who update the app instead of installing fresh? Asking people to un install for an update is not a viable option. Is there something I can do to clean out whatever is getting saved that is causing the app to launch with the incorrect Activity?

View 4 Replies View RelatedI have Activity with ListView inside it and in the onCreate method of the Activity I have code for populating the Data of the ListView this Data is a server based and so populating includes calling Network URLs. I have the ArrayAdapter of the ListView in the Same Activity Class.
Now the Issue I'am facing is that, in Rest all scenarios my Activity is behaving in a proper way but when the Orientation [ Portrait to Landscaped or other way round] is taking place the Data is Getting lost and Newer Data calls are Required to Populate the Same Old Data now this is something that is not intended out the code how should I deal with it.
I have a language setting in my application. When the language is switched, I would like all the textviews etc to change language immediately. Currently I just change the locale in the configuration, so the language has changed when the user restarts the activity.
Solution to my problem would be to make each textview load the new resources each time the language is changed. Is there a better solution? Perhaps a neat way to discretely restart the activity? Or maybe just force reload of the resources?
This is the second time this has happened to me now. I changed the starting activity of my app, and put out an update, and now the icon on people's phone will not open my app. The only way they can open it is through the downloads section of their Android Market app, or if they uninstall and reinstall the app, causing them to lose ALL their data. I have no problem with updates on my N1, but every other Android phone has a problem with this. Why?
View 1 Replies View RelatedI 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.
View 3 Replies View RelatedMy app is comprised of a set of reusable Activities that other apps can reuse.

View 1 Replies View RelatedSo I have an app with Activity A. The layout on the activity is dynamic genearted. So it's possible that on Activity A a user hits a button that goes to "A" and the new page looks different, then a user clicks another button to go to "A" again. Now I have 2 Activities in the history stack. A, A, and currently on A. Is it possible that if a user clicks a button that the whole Activity stack is cleared in a scenario such as this?

View 1 Replies View RelatedI have a problem to start/create Activity in landscape mode. My Activity need to start in landscape mode and be used in landscape mode by users. So far, I used setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) to force screen orientation of my Activity to landscape mode in onCreate() method.
In addition to this screen mode requirement, my application need to start another background thread in onResume() method, and this thread takes some seconds in order to finish an initialization process, and it is not desirable to to stop/restart this thread's service during the initialization process.
However setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) forces my Activity restart in a very little while (means onCreate->onResume->onPause->onStop are executed twice at the first place). As a result, my background thread be stopped/restarted during the initialization process, and this makes me a mess at this moment.
The default behavior from my observation is if current activity force closes Android tries to go to previous activity on stack How can I control this behavior? I want force close to close all activities

I'm writing an application that starts with a loading activity. In the loading activity the app requests html from web and parses the html, then it sends the parsing result to the main activity. The main activity has several tabs, and contents of these tabs are based on the result of parsing.For example, the result of parsing is a list of strings ["apple", "banana", "orange"], and I need to pass this list to main activity, so that the main activity can create three tabs named after three fruits.I would like to know if there is any way to pass a list of strings among activities, BTW, is it the common way of do this?

View 5 Replies View RelatedI'm working on an app that launches the browser activity to perform a Twitter OAuth authorization. This process uses a callback url which will re-launch the activity that started the browser activity in the first place.My problem is that the browser pages remain in the history stack and when the user then clicks back from the preferences activity that launched the browser in the first place, they don't go back to the app's main activity, but instead are brought back to the browser. I've tried adding flags to the launching intent to prevent history and reset on clear, but it doesn't seem to work when running on my phone, only on the emulators.
View 1 Replies View RelatedI have an application with contains multiple activities. The main activity will start the others ( use startActivity() ) depends on user event, when an activity close, it calls finish() and return back to main activity. It appears to behavior like that.
However, the "problem" I see is main activity's onCreate function is called every time. I think the the main activity should be placed in the activity stack and simply push to front when others exit, therefore only onResume, onStart are called. Is there some flag I need to set or I misunderstand the activity behaviro?
In child activity, besides calling finish() or startActivity for main activity, what is other way to move main activity to front?
I created an application which enables the user to set whether he wants to receive notification while the application runs in background mode. If the notifications are enabled an activity should be started (the dialog should appear on the screen).
I tried to enabled it the following way:
CODE:...........
This is the method from main activity. When onPause() is executed isRunningInBackground is set true.
When I tried to debug it when the main application was running in the background the line
startActivity(intent) had no effect (the activity didn't appear).
Does anyone know how to midify the logic in order to start an activity from the main activity when the main activity is running in the background (after onPause() is called)?
I have an activity that starts a long-running service which in turn adds an icon to the status bar. When the activity gets invisible, e.g. by pressing the Home button, and the pressing the icon in the status bar a new activity is created instead of showing the already created activity. If you now press the back button the new activity is destroyed and the activity created in the first place gets visible. How do I make the invisible activity brought to front when pressing the icon in the status bar instead of creating a new activity?
View 1 Replies View RelatedNeed an example of how to create/start a new activity from the main activity. I have a button click event on the main layout. Originally I just used setContentView(R.layout.secondactivity); which brings up the layout but I don't think that is correct since the secondactivity class is not instantiated at this point yet. I have looked for such an example and can not find one.

There is also a widget that will display important info and add data to the database. When the widget is clicked, a configure class displays a way for the user to edit data. When the configure activity is done, the widget is updated and instead of going back to the home screen, the apps main activity is started. I can't find where the main activity is being called from. Wouldn't I have to create an intent and start Activity() to get this behavior? When done updating, I want the home screen and not my app.
