Android :: Possible To Define Each Tab's Content In A Separate XML File?
Jun 28, 2010
I would like to define each tab's content in a different XML file so the visual editor in Eclipse can be used. That is, without all of the tabs being laid over each other. The visual editor doesn't even seem to work with the XML example provided here: [link text][1]
[1]: http://developer.android.com/guide/tutorials/views/hello-tabwidget.html "Here", It just has a Null pointer exception.
I have tried to define each tap in it's own file, for example. code...
And when adding the tab I use:
mTabHost.addTab(mTabHost.newTabSpec("tab_in").setIndicator("Input").setContent(R.layout.input));
But this causes the application to crash on launch. Is there any way to do this?

I have some problems finding the documentation of the definitions of shapes in XML for Android. I would like to define a simple circle filled with a solid color in an XML File to include it into my layout files.
Sadly the Documentation on android.com does not cover the XML attributes of the Shape classes. I think I should use an ArcShape to draw a circle but there is no explanation on how to set the size, the color, or the angle needed to make a circle out of an Arc.

I'm currently developing an Android application, but I'd like to be able to handle button click events etc in a separate file for each Activity. Is this possible? At the moment, I have one very large file that handles all events for several Activity windows.

I am new to android development and am currently working my way through the "Hello..." Tutorials on the developer website.
I got stuck on the Tab Layout walkthrough and the only way I could resolve it was to put each Activity Class in a separate .java file.
I was wondering if all Activities need to be in separate .java files, or am I missing something.

I'm using a default Eclipse project file generated for my Android application, and I want to keep it in a targets/ directory (along with other eclipse-specific files) in order to better organize my project structure (I also plan on adding a target for NetBeans).

Is there a reason why the Thread class in the SDK LunarLander and JetBoy examples are not each in a separate java file, rather than being inside the View file?
It would make things a bit clearer, IMHO. Am I missing something?

I know the absolute path of an image (say for eg, /sdcard/cats.jpg). Is there any way to the content uri for this file? Actually in my code I download an image and save it at a particular location. In order to set the image in an ImageView currently I open the file using the path, get the bytes and create a bitmap and then set the bitmap in the ImageView. This is a very slow process, instead if I could get the content uri then I could very easily use the method ImageView.setImageUri(uri)

In android it is not directly possible to share files and folders across different application. The only way is Content Providers.
1. Is there any general (any file type) content store? Today there is Audio, Video and Image Store.
2. Wanted to write new Content Provider to store Big files, like Video and Audio. Saw some examples, like

I need to write a ContentProvider to provide a dynamically generated audio stream to be playable by MediaPlayer. That is MediaPlayer will use ContentResolver.openInputStream() to play it. I have read a lot of discussions about this problem but no one had a solution yet. The most recent one was in January 2010: http://groups.google.com/group/android-developers/browse_thread/threa.

I do an import of the full package name / java file, and if I do a <classname>.<method>, SOMETIMES I can get it to access - other times I get a lot of can't use a static in a non static bunch of talk. I'll admit I'm new to Java, so what do I need to do? Call a class instance first, then call my methods? I'm rather confused by this, as I want to put all of my 'functions' into a FunctionsList.java file, and all of my main Activity (UI) into a MyActivity.java file.
For example:
<MyActivity.java>
import com.example.FunctionsList;
private class MyActivity extends Activity {
FunctionsList.function();
}
9/10 times I get that static/non-static error. If I put all of my functions into MyActivity.java, I have zero problems!

I'm now trying to implement my own content provider. My original data was stored on network or local/remote file systems, so I want to provide data via input stream. I know that client may call ContentResolver.getnputStream to retrieve the input stream to access data. But I don't know how to implement content provider in this situation, I searched the Internet but all the tutorials for content provider are talks about how to expose data that stored on local database. how to expose data that stored on file systems using a content provider? what happened when client call ContentResolver.getnputStream? I want to know how to return an input stream to my client.

With Android, you can define different resources for different phone attribute by naming res directories appropriately. I need to be able to support different layouts for 480x800 and 480x854. I figured I could have one set of resources stored in the layout-hdpi-v4 directory and another in layout-long-hdpi-v4. However, both resolution seem to think that they are long (at least based on the emulator, which I understand may not reflect devices accurately). Is there another way in which I can distinguish between the two resolutions/aspect ratios?

I'm starting to design my object graph for an OpenGL ES 1.1 app on Android. What's advisable when it comes to actually drawing my triangles and controlling their size? Should I store all the vertices in units relative to each other and then multiply them by a value I pass during a draw(GL10 gl)? Would this approach have any impact when it comes time to do frustum culling?

I'm porting android to Devkit8000 which is a BeagleBoard clone. I have a GPS module connected on /dev/ttyS0. I could successfully get NMEA output when writing "cat /dev/ttyS0" in the terminal emulator.
I want to know how to let android know that there is a GPS module on /dev/ttyS0 and it is outputting NMEA standard? To be able to use the android.location class with it! or test it with any GPS app in the store!
Is there something to edit in the android's source? adding driver for example, writing a code with android-ndk or what?
