Android :: Design For Droid Apps Ever-changing Screen Dimensions?

Aug 2, 2010

I'm a web designer by nature, accustomed to changing resolutions and font sizes, but I'm unsure how to design for the Android platform without knowledge of screen sizes, especially when the screen rotates from portrait mode to landscape.

Should I just do generic things that tile, or is there a way to design things of static size?

By this, I mean for the GUI and graphics, not element nodes of the XML.

Android :: Design Strategy - Large HTML In Apps Bookmark Location

Nov 8, 2010

I write Windows/iPhone/Android apps that mostly display large documents (HTML) in an HTML container view. What is a good strategy to determine where in a document the users has scrolled to so that when the app runs again, it goes to that location in the HTML document? ll of my software can 'listen' to javascript. Is there a way to find in a HTML page, perhaps with javascript, where the visible section is?

Android :: Can I Save Energy With Color Scheme?

May 25, 2010

I'm wondering what color-scheme is more energy-saving for AMOLED display? I've already decided to manage c-scheme according to ambient light, thanks to this post: Somewhat-proof, the link posted by nickf: Ironic Sans: Ow My Eyes. If you read that in a well lit room, the black-on-white will be the most pleasant to read. If you read it in a dark room, the white-on-black will be nicer.But if I want to save battery power, should I use bright content with dark background or vice versa?Is it possible anyway (they say it's not working for simple LCD)?

Android :: Intent Filter For Http Scheme

Sep 14, 2010

I built an Android application that requires OAuth. All was working well using a custom scheme call back which is intercepted by Android. It seems that Yahoo have changed the goal posts and now the custom scheme is not accepted by Yahoo.I am now looking at possible alternate approaches. My first attempt is to use a normal http scheme and modify my intent filter to intercept the new URL. I have the following in my AndroidManifest.xml :
<action android:name="android.intent.action.VIEW"></action>
<category android:name="android.intent.category.DEFAULT"></category>
<category android:name="android.intent.category.BROWSABLE"></category>
<data android:host="" android:scheme="http"></data>
Where will be substituted with a domain that I own. It seems :
* This filter is triggered when I click on a link on a page.
* It is not triggered on the redirect by Yahoo, the browser opens the website at
* It is not triggered when I enter the domain name directly in the browser.

So can anybody help me with
* When exactly this intent-filter will be triggered?
* Any changes to the intent-filter or permissions that will widen the filter to apply to redirect requests?
* Any other approaches I could use?

Android : Chart Using Scrollview

I want to draw a chart and I'm using a scrollview to do so. my scrollview holds the chart view. What I've observed is that the scrollview's onDraw calls the onDraw of my chart view.

Android :: Understanding Proper Alarm Flow

Jan 11, 2010

the app I'm trying to implement allows the user to select a sound file (MP3 or WAV) to play at a specific date and time showing a dialog with a progress bar and an OK/Cancel button allowing the user to stop the playing of the sound file. I want it to behave something like the countdown apps I've seen or even the built-in alarm clock app. As I'm implementing this simple (I thought!) app, I'm trying to better understand the platform and make the application conform to the Android way.

As I've been writing the app, I learn more about how things are supposed to work on the Android platform. And here's where I'm getting a bit confused. During my attempts to get the alarm to fire and display, I'm learning that properly formed Android applications are not supposed to show dialogs as a result of a background service or broadcast receiver being invoked through Android's alarm service. Instead, I think, the app is supposed to use a notification on the status bar to alert the user. The user then has the option to look at the notification to see what the app is trying to tell them..............

Android :: Activity Flow During OAUTH Authentication

Feb 3, 2010

I think that I've found the problem I am having with AccountManager that I described in an earlier thread that got no responses on the board.

I think it is a problem with the way that the Activity Stack is working during the OAUTH workflow. Here's the workflow as I see it. I found this problem by separating out my Activity, which I'll call M, from the oauth Activity, which I'll call O. In the course of authentication, the web browser is invoked and let's call that B.

When a user needs to start over with authentication, my application, through Activity M, starts Activity O. That, in turn, generates some magic URL that is sent to the web browser. So the browser is fired up and information was sent to the OAUTH provider to do a redirect back through the browser back to Activity O.

So, this how the OAUTH workflow looks up to the browser: M -> O -> B

At this point the user logs in and hits the Accept button and the browser then invokes my BROWSABLE activity, which, again, is O. I had thought this would unwind the above stack, but it seems that above situation disappears and what I have after the user hits Accept in the browser is this: B -> O

What I did to work around that is that I put a startActity(M) in O and that seems to work, but it is a workaround.

I believe there is something that I could do with launch modes or activity modes to fix this problem and maintain the original activity stack.

All that is happening, really, is that the O activity pauses for little while, then comes back with the goods, the login credentials. But when I tried to return the information via startActivityForResult (), nothing. Because M is no longer on the Activity Stack.

Android :: Specify Scheme Specific Part In Data Tag For An Intent-filter?

Feb 3, 2010

I want to set up a BroadcastReceiver to handle PACKAGE_REPLACED, but I only want to be notified when my package is replaced. It works fine if I specify a data tag with scheme="package" but then I get notified when any application is reinstalled or upgraded. I can't figure out how I'm supposed to specify the package name which is in the scheme specific part -- that is, when my BroadcastReceiver gets the intent in onRecieve(), if I do intent.getData().getSchemeSpecificPart(), that's the package name, but is there any way I can filter for only that in my intent-filter?

Android :: What Is Purpose Of Path Pattern If I Cannot Filter Http Scheme?

Nov 16, 2010

I want to capture Intents with a specific Uri pattern that uses the http scheme. I DO NOT want the chooser dialog to pop up. The Android API advertises filtering of intents based on pattern matching of the path part of the Uri: /guide/topics /manifest/data-element.html However, when I try to specify a pattern for my path other than ".*" (which pops up the chooser, which I'm trying to avoid), it doesn't work, and the browser automatically handles the Intent. So, my question is, what is the purpose of the pathPattern/pathPrefix if, for the http scheme, it either auto resolves to the browser, or pops up the chooser anyways?

Android :: Program Flow When Rotating Device With Two Activities

Aug 13, 2010

My first activity is creating a second activity within its onCreate:


The second activity has EditText views for the username and password along with submit and cancel buttons. When either button is pushed, the text from username and password is sent back to activity one (via onActivityResult), which connects to a server to see if the username is available. While connecting to the server showDialog is used to show a ProgressDialog. When the server responds, the ProgressDialog is dismissed and an AlertDialog is shown. This works fine as long as the device is not rotated.

Here's the problem: if the user rotates the device from within the second activity and pushes submit, the first activity re-invokes its onCreate, which ends up launching the second activity again since the username and password are still null.

Does anyone have any suggestions to get around this?

Is there a method that could be used to pass data from activity-2 to activity-1's onCreate? I wouldn't want to use a database in this case, as that seems like overkill.

I've thought about containing the server communication and dialogs to activity 2, but then I'd have duplicate server code in activity 1 and activity 2 (activity 1 connects to the server for other things too). Another issue I'd have with this approach is that the user has an option to cancel creating the password, in which case I want the app to finish. If I called finish from activity 2, activity 1 would appear and I don't want that to show unless a username and password have been created.

It just occurred to me - if I could replace activity 2 with a dialog it might make things simpler. The dialog view needs to have 2 EditTexts and 2 buttons. Can I create something like this and use the showDialog method?

Android :: Multiple Process On Separate Development Flow

Jul 14, 2009

I need two activities run in different processes in the same application. Now I have made it work by specifying the different process name in "android:process". But I met a problem, from, we have only one superclass of Application will run before the activity starts(I have tested it, and each time a after new processes start, this Application(its superclass) will run before activity). But, my two activities have two different superclasses of Applications.

So, how to make Applications for different activities run for its corresponding activity? If there is no way to use different Application class for different activity, how can I make a flag for the common Application superclass to judge which process(by getting its name) is running? BTW, the two activities were on the separated development flow and I am trying to merge them.

Android :: How To Control Activity Flow - Back Button Versus Home Button

Sep 2, 2010

I have 3 activities in my app: Activity1 -> Activity2 -> Activity3. Inside Activity3, if the user presses Back, I would like to return to Activity2. In Activity3's onPause event, I added a finish() statement. That's probably not even necessary, but I wanted to make sure this Activity gets cleaned up. This works fine.
However, while in Activity3, if the user presses Home or starts a new app (through notification bar or some other means), I want both Activity3 and Activity2 to finish. If the user returns to this app, he should resume with Activity1.

I have figured out how to do one or the other, but I can't figure out how to handle both cases, if it's even possible. Can I trap the "Back" button in Activity3 and send a message back to Activity2 telling it not to finish()? It seems like the Activities follow the same lifecycle flow (Pause, Stop) regardless of what you do to send them to the background. Just to answer the question of why I want this behavior, imagine that Activity1 is a login screen, Activity2 is a selection screen, and Activity3 is a content screen. If I press Back from the content page, I want to be able to make a new selection. If I exit via any other means (Home, notification bar), I want the user to be "logged out".
