Android :: Design Flow Chart Scheme For Apps?Oct 7, 2010
I'm seeing that it would be good to have some sort of charting scheme (or possibly just a table-based design strategy) when designing Android apps.Have any such schemes been proposed?

What are the best practices to design webservices for mobile (particularly Android) apps?
Personally I'm focused on using JSON (and not XML) and I try to make it the less verbose I can. But I'm probably missing a lot of things.
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.
not sure if this is the right forum but here it goes, I want to see if anyone knows if u can change the color scheme of the apps on the windows/ screen to let's say black and white, FYI I am rooted with 3.21 if that helpsView 1 Replies View Related

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. Now I draw the entire chart on the canvas when the onDraw of chart view is called. Also scrollview's onDraw is called everytime I scroll the view. So I end up drawing the entire chart multiple times. Is there any better way to achieve what thisView 1 Replies View Related

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)?View 4 Replies View Related
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 :
<data android:host="www.test.com" android:scheme="http"></data>
Where www.test.com 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 www.test.com
* 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?
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..............
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.
Can you please tell me if there is a way to layout textaround an image?I have gotten a response from an android developer about this question. But I am not sure what he means by doing my own version of TextView? Thank for any tips.This is not possible using only the supplied widgets and layouts. could write your own version of TextView to do this, it shouldn't be hard.View 2 Replies View Related

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?

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 http://developer.android.com/guide/topics/manifest/application-elemen..., 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.

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?View 1 Replies View Related

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:http://developer.android.com /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?View 1 Replies View Related

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".
When the person opens my app, I want to display a button. The user clicks this button, and it opens a browser (embedded, of course) inside the app, allowing the user to LOGIN through that web page.
Of course, when the person logs in, it only logs in to that web server. The web service now knows that the user is logged in.
As the user uses my mobile app, I need to know if he's logged in or not. How can I know? There's no way for my app to determine if the user is logged into my web service.
By the way, I am using Django framework for my web service.

I'm kind of new to android development.I have read from many sources that findViewById() is a "costly" operation. I'm making an application that deals with 5 TextViews to provide different kinds of information (distance, duration, title, description, etc) from a database. I'm using listeners to catch touch/click events and feedbacks a handler. The main function of the handler is to received a "position" in the Cursor where the new information needs to be displayed. I mentioned earlier that findViewById() is a "costly" operation. So, I don't call this method in the handler. Doing so, it will retrieve every time the Views when user touchs/clicks some widget. Is it right to populate the Activity with private members of the Views/Layout it displays? I mean, I don't like it. I don't know why, but seems that I'm populating too much the activity. I'm aware of the android:onClick xml attribute, but in my case I also use long click listeners. So, a piece of onCreate() looks like: And all of those are private members, wihout mention the "cursor.getColumnIndex()" for each. I thought on implementing Handler.Callback and set on the Hanlder.Callback constructor implementer a View array or a View list or something, but I also need this objects later to set other listeners and setups. Is this right? I cannot think another way, as I need the reference to the object, and also the Cursor reference that the handler will move to the "position" provided and update the correspondent View. I will really appreciate either an advice or a useful link/info/doc to read in what concern in this kind of designs. What I do not like is that It looks like imperative programming filling the Activity with "global" variables.View 6 Replies View Related
I'm asking if anyone else has had the same problem as me. After about a week of having my phone I found the charging socket would only work intermittently. I had to push the cable towards the front to get it to work.
I duly called orange customer services and they arranged a courier to switch it for a brand new one, top job there, I'm not sure how long that warrenty lasts though.
Now the new one, arrived precisely 5 hours and 31 minute ago, I placed it on charge very carefully and waited for the light to go green.
