I'm working on an app that is meant to be used by fans of a sport team. In the future, I expect to use the same app but for any different team. So, what changes would be the colors, team logo, app name and the like. So, is there any technique that allows me to build binaries for different teams without having duplicated resources?

I am looking to create an Android application that uses Tabs.
Requirements
- When a user selects a tab and gets back to the same tab, there shouldn't be a loading period (preferably).
- Each tab will contain a listview.
- In one of the tabs, I will have to use subtabs. And that's it.
One great example I really liked (although I didn't try the app) is

I'm currently working on an application which need security features. My question is simple, if every application is signed by its developper, how can I access application public key? (and private).
View 6 Replies View RelatedI used Eclipse with the Android SDK to develop the original application. I ask since this was my first Java (and Eclipse, and Android, and XML) project. I assume that most of the Java should run on the PC without too much trouble. I may want to restructure the code to isolate the Android specific functions. Should I stay with Eclipse or move to something like NetBeans?
View 3 Replies View RelatedFor my first application, the only testing I've really done to this point is on my Droid X. I want to think through the various hardware differences and come up with a testing plan that is representative of the Android landscape. My initial thought is to create a list of emulators that have unique qualities such as screen size and SDK levels. I've noticed very quickly how the UI of my application will need some adjustment when viewed on devices that don't carry a 4.3" screen. How have you approached this hurdle in your own development?

View 9 Replies View RelatedI'm a total newbie to Android (and to Java in general... mostly a PERL/ PHP guy here...), so forgive me if I use the wrong terminology to refer to things... I have been asked by my company to implement an application for Android that allows a user to enter a note at the end of every call. E.g., either they or the other party hangs up, immediately a notes area pops up with a "save" button and if they enter a note, the note is saved with a reference to the call log entry. As I understand it, onCallStateChange() will give a pretty good indicator of a hangup if the state has become Telephony Manager.CALL_STATE_IDLE. I've figured out how to do the UI part, how to save it in a database, etc... My question, however, is about how I implement this "listening" aspect of it. Should I have a service running all the time that has an instance of android.telephony.PhoneStateListener? If so, do I use the onBind or onStart method, and how do I make sure it doesn't go away when memory runs low? Or can I somehow attach the listener to this event, and then terminate? Or is a Broadcast Receiver the way to go?

View 5 Replies View RelatedWe are supposed to cache textual and audio data in our application until device is booted or maximum of two days, whichever happens earlier. To get a perspective on data to be cached, note that we are to store about 200 text headers containing around 10 fields, each of length 30 bytes and about 20 sound files each about a minute long.We are getting the textual data by parsing XMLs and then we keep them in ArrayLists. The sound files are directly written inside the app storage using File I/O (and not on SDcard or Apps Cache directory).This application is to be run on devices running Android 1.5 or later.I understand, and please correct me if I am wrong, that we can cache the files either on SDcard or inside the application or inside applications Cache directory.
View 2 Replies View RelatedBackGround: There are Facebook APIs(and SDKs) available to develop applications for other Mobile devices like iPhone, BlackBerry etc, but it seems there are no official ones for Android(?).
People have ported Java APIs to work on Android and have written FaceBook Client applications(FaceBook dev: Wiki Page). Apparently, there is also a light weight FaceBook SDK in alpha release for Android(a la FBRocket). But it is not avised to be used in Production.
Since these FaceBook functionalities have been exposed as REST based service, most of work would invove sending requests in desired format over Http. So, writing a FaceBook client app for Android certainly is doable.There are similar applications already in market e.g.: Bloo.
Questions: When asked to write a FaceBook client application what approach should one undertake? Should we choose the SDK or invoke the services over Http?
If there is already a Web application that integrates with FaceBook, can we just browse to that Application from inside a WebView and be done with this?
I turned on my Droid this morning to listen to MSNBC and I heard the last 5 minutes of Keith Obermann (5:55 am est) and then all of my news and talk channels disappeared! Channels like CNN, C-SPAN, MSNBC and NPR are all gone from my favorites and the channel line-up. There is nothing in the "News and Public Radio" category.
Has anyone else noticed this? I'm thinking this must be a temporary glitch but I would hate to lose all of these channels. If you have the Sirius/ XM radio app, would you please check this on your Droid?

Eg: Lets take FACEBOOK or TWITTER as the website.The application which I design should intimate me about the new posts or tweets of my friends. At the same time I must be able to post or tweet just by opening a text box in the application and writing in it. As soon as I write, the message should get posted or tweeted on the website.
I am not sure about the complexity of the above application but I feel this would reduce the trouble of opening a browser, typing the website name and then logging in by putting the username and password.

View 1 Replies View RelatedI need to build compass for my application.
From reading the documentation it seems there are two reasonable ways of doing this:
Sensor.TYPE_ORIENTATION method: This is the easy way of doing it. The problem with this is it is not accurate. When I compare my reading with Snaptic Compass it is about 10-15 degress off which for my purposes is unacceptable.
Sensor.TYPE_ACCELEROMETER, Sensor.TYPE_MAGNETIC_FIELD and getRotationMatrix() in conjunction with remapCoordinateSystem() and getOrientation() method: The documentation says this "is usually more accurate". The problem is regardless of the delay I register with listener the compass goes crazy even when the device is stationary on flat surface.

Has anyone got the WikiNote from

What I did was:
1) Checkedout the project via apps-for-android instructions
[svn checkout http://apps-for-android.googlecode.com/svn/trunk/ apps-for-android-read-only]
2) Opened a new Android project using existing source dir [per the WikiNote direction]
3) Cleaned the project and let it rebuild
It won't build the APK though and reports compilation errors (the top level dir is flagged red in eclipse but nothing else is so I can't track down where the error supposedly is)

I am currently finding about how to build a XMPP client application on android 2.1.I came across this link which somewhat talks about the same problem.I am a newbie to android dev and thus found the solution given there to be difficult to digest.
The system currently has Active MQ as a JMS provider.My job is to fed the messages coming from JMS to the XMPP server and then develope XMPP client on android 2.1 which will listen and show notification to the events pushed by the server. I have following concerns(which might sound foolish)
1.How do I push the events from JMS to the XMPP server which will in turn push them on android?
2.Which XMPP server implementation I should use?I have 3 options....................

When I executed the make command, I got an error here like this build/core/java.mk:20: *** frameworks/ex/common: Invalid LOCAL_SDK_VERSION '8' Choices are: current 4 5 6 7. Stop. Then I changed the frameworks/ex/common/Android.mk to LOCAL_SDK_VERSION = 8 from LOCAL_SDK_VERSION = 7. Next place, build/core/java.mk:20: *** external/jsr305: Invalid LOCAL_SDK_VERSION '8' Choices are: current 4 5 6 7. Stop. I changed the external/jsr305/Android.mk to LOCAL_SDK_VERSION = 8 from LOCAL_SDK_VERSION = 7
Last one, build/core/java.mk:20: *** external/guava: Invalid LOCAL_SDK_VERSION '8' Choices are: current 4 5 6 7. Stop. I changed the external/guava/Android.mk to LOCAL_SDK_VERSION = 8 from LOCAL_SDK_VERSION = 7
By these changes the code started the compilation.
1. Why the error occured?
2. Changes which I did is correct or not?
I doubt there are too many people who run CDT in eclipse for native apps also with ADT installed for Android, but in the off-chance that someone here knows anything about this, my problem is that any time I run any android app, my C builder kicks in for projects totally unrelated. I have no idea why and have been digging through settings on everything, unable to find out why. All I can think is that the ADT pre-launch process triggers it via a refresh or some kind of catch- all type call in eclipse API land that I'm unaware of. Does anyone know anything about this? It's very annoying to have a C builder run for a different project than the one you're working on every time you launch the app.

View 2 Replies View RelatedI'm navigating through a 3-level hierarchy of names to get to a document view page. I've set up tabs for the 3 levels. The tabs are left, middle, and right where the right tab is the lowest level of the hierarchy. Each tab has a list of 10 to 20 Radio Buttons with the names. This all works great and is very efficient and intuitive. One note is that there may be 1000 documents available (from an online source) but the average user will only be viewing a handful regularly. So I store the choices for each of the 3 tabs. This way a user can quickly navigate to his favorite without having to negotiate the entire hierarchy each time. My question comes when the user is on the right tab. At this point they have navigated through to the document they want and I'm wondering what is the best way to initiate the document view page. Remember that most of the navigation happens on the right tab in the small set of documents the user regularly visits, with only occasional visits to the other tabs. So making the right tab efficient is good. My current approach is to add a LongClickListener to the buttons of the right tab. Then a press-and-hold kicks off the document view. This certainly minimizes the number of objects on the screen and the number of separate clicks required to get to the document but I question whether new users will know that a long press is expected. I guess I could put up some Toast if the user doesn't do anything for 5 seconds but that still seems clunky. Another approach is to add a Button at the top of the right tab Radio Buttons. This has the merit of being dead obvious but it's a less efficient use of screen space and also an extra click for an experienced user.
View 9 Replies View RelatedI'm trying to build a radio application for Android.I'm an android newbie,but familiar with Java.Could anyone tell me the procedure for streaming audio from an internet radio station onto my android device in detail?
View 1 Replies View RelatedI am required to work on an application which is be deployed on devices running Android 1.5. The application is supposed to maintain a connection with a server and regularly poll it for new data. The server will notify the client of new data following which the client will connect to the server and download the data.I know that ideally a push based approach will be more conducive here given that we are to run this on a mobile platform. Also, from Android2.2 there is going to be support for C2DM(Cloud to Cloud device Messaging) but as already mentioned this application is for devices running Android1.5.Implementation: I was thinking of using AlarmManager which would Broadcast Intents periodically(poll interval), The Broadcast receiver will then try to connect to the remote server and make data changed check. If the server has an update, the thread will connect to the remote server and download the data from the server.
Problem and Issues: 1. Is this the right way to approach the problem? 2. Is AlarmManager reliable? Would it remember Alarms after a device boot? (I think it does) 3. How do I ensure that battery usage is kept at minimum.(I have heard something about using "keep-alive" to sustain the session for longer time..what is this legend?) 4. What are other things that I need to consider? I am sure I must be missing lots of things here.
