I know this question was asked couple of times in this list, but I haven't found any answer in archives, and last time this subject was debated almost a year ago. Does anyone knows is it now possible to somehow extend contacts functionality (for example: add custom field for VoIP phone number in which case user can use it to start custom activity for voip)? What are Contacts.ExtensionsColumns for?

Adding "floating window" to the long press context window of an app icon and/or a system setting for double clicking the app icon to open in a floating window. I don't Dev. This is a freebie. Would be a cool PA/CM/AOKP option.

I would like to be able to create MultiAutoCompleteTextView that will filter contacts the same way, to make contact selection easy in my app. using the mms app is cumbersome since it uses internal apis and has everything split across classes.
Has anyone made an easy way to do this?
I'm just getting into Android development, coming from a mostly ruby and scheme with some Java background. For a first project, I decided to try and build a stopwatch.
The included Chronometer widget doesn't quite have the functionality I wanted, so I copied its code into my own package. However, when I try to build it, I get the following error:
CODE:...............
If I remove the RemotableViewMethod annotation, the code compiles, but crashes with an IllegalStateException as soon as I call a method on the widget, as seen in this stacktrace: http://www.pastebin.org/50243 .
Looking through the android source, you can see stock widgets using the RemotableViewMethod all over the place, but for some reason, my code can't.
So, my question is this: What can I do to enable the RemotableViewMethod annotation in my custom widgets? Is there something I should be doing differently in order to code custom widgets?
I have trouble (example<http://groups.google.com/group/android-developers/browse_thread/threa...>) wrapping my head around styles/themes. Can somebody help me or point me to actual documentation?
Let's say I have a drawable that I want to use as the background of a layout:
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle>
<gradient android:startColor="#9F9FA4" android:endColor="#66FFFFFF" android:angle="270" /> </shape>
Now I want to have a dark and a light theme. Depending on the chosen theme I want to have a different value for startColor and endColor. How do I do that? I am aware of extending themes, but what do I put into the items? How do I reference those new values then?
I want to extend the built in media player, however when i grab the sources, there are a lot of external dependencies that are hard to track down. Is there any way to get the source and the dependencies so that i can have it as a standalone and then extend it, is this even possible?

Ultimately I wish to produce a compressive Contact Manager with some specific features. I thought it would be good to experiment by extending Contact. So using git I checked out froyo-release and tried to build it. That didn't work so well as it contains things like
Suppress the internal stuff under the assumption that I really don't need it. Start with a toy Contact Manager and implement (reinvent) everything.
My guess is that I am going about this incorrectly. "I want that third alternative" --kirk.
Just for completeness, the new special behavior is to provide an action list for a contact based on the types of that entities data.
Im using the NotePad example as a base for an application. This binds a ListActivity to a Provider.
Its perfect, except it uses SimpleCursorAdaptor, which means the list only binds to and displays one item per row. I want it to display two items, both bound the Provider. Or more accurately display the text from one Content Provider field and an icon which depends on the value of a different field.
This sounds like a pretty simple thing to do, a very slight modification to the NotePad application. Trouble is, I have no idea on *how* to do it. I really need a starting point, and "approach" to use.
So far I have tried (unsuccessfully):
* Hand populating the ListView by reading in the Provider data and populating an array in OnCreate. This works, except as the data is not bound the List does not update when I add an item.
* Extending SimpleCursorAdapter with a custom getViewBinder. Could still only bind to a single column.
* Building my own ListAdaptor. Couldn't get this to work.
* Concatenating both fileds together and "parsing" 2 fields into 1 field read/write.
The next thing I will try is extremely tacky running two separate simpleCursorAdaptors in two views in a Linear Layout, fudged so the row height is identical, and duplicate the logic.
I say this only to show that I really, really have tried.
How I can create a custom CursorAdaptor which binds to two fields instead of just one like SimpleCursorAdapter?
Is there a way to extend Webkit on Android? Can we write plug in for webkit in android? Can we do things like creating our own renderer for a particular type of data embaded in the webpage? Can we track user session or modify data stored in the browser cache/memory?

View 1 Replies View RelatedI'm creating a custom widget that extends AdapterView. Imagine something like a ListView except that the list items can overlap each other with some transparency. Because of the overlap, I'm trying to control the layout and drawing order of the children.
My issue is that the control renders it's children, but ONLY one level deep. Each child is inflated from an XML resource that contains a FrameLayout and an ImageView. The FrameLayout draws, but the ImageView is never visible. I assume I need to call some method to tell the FrameLayout to layout or draw it's children, but I'm not sure what, why, or where. Does anyone know what I'm missing?

In a book I read, the author suggests to extend the application class in order to have a place to be used as a singleton. In this way, it is easy to make some initialization stuff in it onCreate().Now my question: if my application has also some broadcast receivers declared in the manifest, and the application was not started explicitly, or it was but then the os reclaimed it resources back, what will be happening if the broadcast receiver is triggered? Will the onCreate of the application class be called first?
View 7 Replies View RelatedWhile programming on Android, I end up writing a parent activity which is extended by several others. A bit like ListActivity. My parent activity extends Activity. if I intend to use a Map or a List, I can't use my parent activity as superclass - the child activity can only extend one activity obviously. As such I end up writing my parent activities with the same logic for Activity, ListActivity, MapActivity and so forth.
What am I looking for is some sort of trait functionality/design pattern which would help in this case. Any suggestions?

The SurfaceView doesn't seam to have an onMotionEvent to override. Is there anyway to capture onMotionEvents with a class extending SurfaceView?
I just got my HTC Desire with Android 2.1, and the first problem I'm running into a lot is when using the visual keyboard. Being multilingual and having friends who only speak one particular language, there's no single 'correct' input language setting for the word prediction feature, so I started looking into how much work it might be to extend the keyboard with two rather basic, though essential, features:
1) Showing the current language selection, so that I don't have to type stuff, getting it mis-corrected, then discover the language setting must be wrong, go into the settings, select to change language, select language, etc. until I get back, erase the old text and start over. That gets old real quick.
2) Being able to simple change whatever language is used for the word prediction by just having a button on the keyboard doing that directly, i.e. a button that just cycles through the 'relevant' languages with the key label showing which is currently active. Improving it even further, one might imagine:
3) Having a per contact setting, noting the word-prediction language that should be used when communicating with that user. But searching through the docs, I'm slowly coming to the realization that the input text language setting may not even be available to be changed outside the system settings dialog, making this impossible to implement - is that correct?
I am trying to create a simple 3-D app for android that will have an additional view layered on top of the OpenGL view (much like the SurfaceViewOverlay example in the API demos). I'm running into an issue trying to implement that method with an extended GLSurfaceView class. I've set up an example where I'm trying to do a combination of this demo with the API Oerlay demo. If I try to cast to a Martin's VortexView object like this (replace lines 44-46 in the API demo) I get a ClassCastException error (which is understandable, as I assume casting is fairly specific) so I guess I'm looking for a method to transfer the view from a GLSurfaceView instance to a new subclass or a way to set the rendering surface to an XML defined view for a subclass after it has been created. it will do the casting correctly with the above code but generates Null Pointer Exceptions when it hits the surfaceCreated and surfaceChanged routines (I think it's the called methods in the GLThread class based on the line number) inside the GLSurfaceView class. So maybe I should change the question- How can I implement an extension for GLSurfaceView without generating NullPointerExceptions on surfaceCreated and surfaceChanged, or how can I debug them without having the source for GLSurfaceView.java? Code...

View 9 Replies View RelatedI've run into the following issue:
Say I have an Animal class, which is parcelable, and I have a Dog class and a Cat class, which are subclasses of Animal and also implement Parcelable.
Say I have a service with the following AIDL interface:
sendAnimals(List<Animal> animals);
Now I'm calling this remote interface from some client application, passing it a List containing Cats and Dogs. What happens now is that android calls the Cat's and the Dog's writeToParcel() methods at the client side, but at the server side, the Animal's CREATOR is used, which calls Animal's readFromParcel() method. So the right data is sent from the client, but the wrong unmarshalling code is executed at the server.
I have tried to put this in the AIDL file:
sendAnimals(List<T extends Animal> animals);
This results in a syntax error from the aidl compiler though.
My current workaround is as follows: - In each specific Animal subtype's writeToParcel() method, I write the class name as a String into the Parcel as the first element. - In the Animal's CREATOR.createFromParcel() I read the first String out of the parcel, and based on that I create the appropriate type and call the appropriate readFromParcel() method.
I think this is kind of ugly though. I would expect the android framework to take care of this for me.
(My application is not actually dealing with animals, this is just to make it simpler to explain the issue)
