I created an application which is asynchronously communicating with the server. When the application makes a server request a new dialog (activity) with "loading" notification is created. The main activity implements methods for handling server responses and I would like to close the foreground activity when the main activity receives the answer from the server.

View 3 Replies View RelatedI have a map activity for which I would like to have the screen turned on as long it's active (the app consists of one activity only). When the activity is paused or stopped I want to return to normal on/off mode. Keeping the screen on works fine while the app is running but when I exit the app the screen stays on as well. What am I missing?

View 2 Replies View RelatedI have two activities running: MainActivity and ChildActivity. Whenever the user clicks in the button in MainActivity, the ChildActivity is launched. What I want to do is this:When the active activity is the ChildActivity and the user clicks the home button then relaunch the application (like opening from the beginning), I want to see the ChildActivity instead of MainActivity that is launched. However; This is happening only when the user clicks from recent activities window. (the window opened when you long press the home button).I had some suggestions actually work arounds and I tried to manipulate onStart, onRestart, onResume, onStop, onDestroy events. But, they didn't fully solve the problem. There should be a smart way out there.

I have an EditText field and I want to pop up a new window/activity whenever a user touches/clicks the field. The new window has some widgets and of course Apply and Cancel buttons. Here is the code how I intercept the onTouch event.
EditText ctlMaskEt = (EditText)findViewById(R.id.mask_field); ctlMaskEt.setOnTouchListener(new OnTouchListener() { public boolean onTouch (View v, MotionEvent event) { popMaskEditor(); return true; } });
Everythings work fine until I click the Apply and Cancel buttons. The API finish() won't close the new window unless I click the same button one more time. Calling popMaskEditor() from a button's OnClick event handler doesn't have this problem.
Is it possible to close/finish activities in activity stack from a backgorund service.
View 2 Replies View RelatedI started to develope an application. When I wanted to close the application I clicked on the home screen, but the app is still playing in the background. Than I tried to click on the "back" key, but nothing happend, so I've created a key event listener for the 'back" key, and inside that method I wrote finish(); Now my app is closing but I think it's still running in the background, because when I go to "manage applications" I can still see it in the "running" tab, and if I press it, I see I can click on the "force close" to actually close the app. What do I need to do in order to really close the app without leaving it open (one way or another)?
View 9 Replies View RelatedI managed to create a secondary Activity, but now I wonder how I can close it again.
public void button_onClick(View v){
finish();
}
works when I'm dealing with just one Activity at a time, but how do I let the secondary Activity close the entire application?
Can finish() be used to close an activity from a service? If not, what is the proper way to end an activity from a Service? I've created an activity from my service and need to close it.

Essentially it is supposed to call zxing Barcode Scanner to scan a barcode on a button click and return the result into an EditText field.

View 1 Replies View RelatedI'm writing a graphic design application for Android where the user can add several images to a document, where each image is stored as a Bitmap object. Each bitmap has roughly a dimension of 800x400 pixels and uses ARGB8888 pixel format (i.e. ~1.5Mb each).
I'm aware that most of the first generation Android devices have a 16Mb heap limit and this limit is 24Mb and larger for newer phones. I'm also aware that bitmap memory is allocated externally, but I'm confused and what the implications of this is.
My question is: How can I tell at runtime when adding a new Bitmap will get me too close to the memory limit?
Before someone suggests "don't use that much memory", I know that one option I have is to limit how many Bitmaps the user can create such that I know this limit is safe for the most basic Android phones. However, I'd like for phones with a bigger memory limit to support more bitmaps and/or bigger bitmaps.
I know to check for OutOfMemory exceptions when allocating bitmaps. However, there will be some situations where I've only got just enough memory left to allocate one more bitmap. After this point, the whole application will be unstable because even allocating small things like strings could cause an OutOfMemory exception. This is something I want to avoid.
I'm not sure how to define "too close to the memory limit", but I suspect something like "don't allocate more than half of your available memory to bitmaps" would work OK as my other data structures I store in memory are small in comparison.
Is there any way for an activity to register for being notified if a wait/force close dialog is shown or alternatively if the user selects force close, a way to detect that in ondestroy()?
View 6 Replies View RelatedSo I read through the SDK docs and I thought that calling a new activity(browser) as part of a task (myTask) will mean that activity* (browser) will close when a user closes the task (myTask) But I am left with a browser window.

Question 1: What is the cleanest way to ensure that when a user closes my app, any outside activities called will be closed to.
Question 2: Does a callback URl start a new Task, or use one in the stack if available?

View 1 Replies View RelatedI have a toolbar view set for most of my activities.
The toolbar has several buttons which all trigger certain intents. Now, the problem is: how can I close current activity before starting another one ?
Problem 1) Activity cones For instance one of the buttons ('A') starts activity A. Activity A also has toolbar. If you press on the 'A' button, a new A activity will be started. I suppose I can look at Activity.getInstanceCount(), right ?
Problem 2) Unnecessary activities The activity X is not needed any more if the opts for A. I just want A then. How can I remove X from toolbar which only has access to context ?
I, of course could find toolbar view inside activity X and override the onClicks, but in general this would mean doing so for all my activities !? Am I on the right track ?

How do I close a whole hierarchy of activities and show a new activity not present in the current task?
Context
Consider a FTP browser that resumes the previous session on launch. Each folder is displayed in its own activity. When I click on a folder, a new activity is started for the folder. If I press the back button, the app returns to the previous activity, which corresponds to the the parent folder.
I can logoff from the menu at any time. Logging off should bring me to the login activity (not present the current task when the app has resumed the session), and close all the other activities. How can I do this?
From what I've read, if the activity were in the current task I could use FLAG_ACTIVITY_CLEAR_TOP in the intent, but this is not my case.
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.
