I've removed my convoluted and badly malformed question so that it doesn't detract from the very neat and correct answer beneath. Given the (surprising) difficulty of finding an on-line example for doing this incredibly common task, I hope Yoni gets a few more up-ticks for his response.
So the question...How do I use Apache.Commons to upload a file to some destination. I'm using it in Android and uploading to a PHP script, but obviously it can work from any Java program and to any HTTP based listener.

1. Can I call ADT Layout Editor in my java source file, not by XML file "open with" menu ?
2. When I click "add" button in the outline view of ADT Layout Editor , it will show such a list of UI components as "AbsoluteLayout AnalogClock AutoCompleteTextView Button ....." My question is where it gets this list? Can I config this path to get my customized UI components?

I'm a novice user writing my first android application. I have the need to upload a file to a webserver from the device. I googled enough before joining this forum and not at one place did I find a suitable solution. I would like to know how to launch the file browser when user clicks on the "Browse" button to upload a file.

Is it possible to build a GridView object in XML with 3 columns and 4 rows of Image buttons? It doesn't seem to have similar containment relationship like LinearLayout or RelativeLayout viewgroups.
I want to do this entirely in an xml layout file. When I put ImageButton xml tags inside a GridView xml body, The layout panel in eclipse is throwing an exception: UnsupportedOperationException:addView(View, LayoutParams) is not supported in AdapterView.

Does anyone know the aximum upload file size for Droid you tube videos on 3G? I'm going to be in an area with most likely no wifi but I'm pretty sure I should have solid EVDO and I need to upload videos, just wanted to know the maximum file size/length for youtube videos and if there's a way to bypass the limit (I really don't care if I ring up 1.5 gigs of data).

I have a dialog with a custom layout, and I try to close it when I press a button:
private void showAboutDialog() {
dialog = new Dialog(MainMenu.this);
dialog.setContentView(R.layout.about_dialog);
dialog.setCancelable(true);
dialog.setTitle(R.string.about_title);
dialog.show();
LayoutInflater inflater = (LayoutInflater) getApplicationContext().getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.about_dialog, (ViewGroup) findViewById(R.id.layout_root));
Button closeButton = (Button) layout.findViewById(R.id.about_close_button);
closeButton.setOnClickListener(new Button.OnClickListener() { public void onClick(View view) { dialog.dismiss();
} } );
}
But it doesn't work.

I have a webview I'd like to display as a dialog. I'd like the webview to fill the entire screen, except for a button below it that I'd like to stay at the bottom of the dialog regardless of how much content is in the webview. Currently my webview fills up the dialog just enough to push the button off the screen. I'm sure this is something pretty easy but for the life of me, I haven't been able to find the magical combination of layouts, views and attribute values to get it to play nice. Just to be clear, I've gotten it so the button floats over the webview but I'd like the webview to stop just above the button and scroll, if that makes sense.

I'm sure this might be a simple question, but unfortunately this is my first time using Java and working the Android SDK.
I am uploading files on Android using the Apache HTTP libraries, in particular using the MultipartEntity.
I'm uploading to a service that allows me to send them chunks of the file, and once complete, they'll reassemble the chunks. I'd like to take advantage of this feature.
Here's the scenario.
File FOO.BAR is 20 MB. I'd split it into some arbitrary chunk size, let's say 1 MB, which means 20 chunks. Chunks #3 and #14 fail (maybe the cellular/WiFi connection was bad). I can now re-upload just these two chunks and everything will be good.
What I'd like to know is how can I read only part of a file (like the data between 3MB and 4MB)?
The file piece should be an InputStream or File object.

Is there anything the Dalvik VM supports (in terms of bytecode) which is not used currently because the .class files don't have it?
As an example, if people would write their own Source-to-DX converter for their functional language XYZ, would they be able to implement e. g. full tail calls although the .class file does support tail calls only under certain circumstances?

So this is related to a question I asked earlier. I am trying to display an alert using a specified layout. My layout is:
And the code to call and show the alert dialog is..
When I run it I get an error saying:
Uncaught handler: thread main exiting due to uncaught exception
android.view.WindowManager$NadTokenException: Unable to add window -- token null is not for an application
I've looked through the android development site and can't figure it out. I think I'm just missing something obvious but the fix isn't jumping out at me. How can I get this alert dialog to display?

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!

How can I add a layout to another layout in java? In xml, you can do it with include. How can you do it in Java without the help of XML? (I need to know this because the number if includes changes dynamically).

Is there any class generators to process web services in Android/Java? I may have to write my own to generate classes against WSDL but I'm trying not to. Also is there one for REST services as well?
If not providing me with discovery service suggestions like disco/wsdl are good enough.

System config is MacOSX with default JDK 1.5.0_16. Eclipse 3.4 The problem is I have a project in workspace that has been developed under JDK 1.6.I don't really want to switch back to 1.5 ( i' would have to clean up a LOT of @Override ) but if i work with this project, after couple of rebuilds - eclipse layout editor not able to display preview. Work around i found so far open android project that is in compliance with Java 1.5. Close everything else and rebuild workspace. But it's kind of annoying to do it every time.

Ok o my program i prefer to make the layout in java but i was wondering is it more efficient to make it in xml? i dont wanna test both and see whats faster but it feels like when my program call the oncreate (which is where all my layout building code is) takes about 2 secs to load, will loading a layout from xml be faster?
Also a second question, i know you can allocate two different layouts (one per landscape or portrait) but does it till rerun oncreate when you do this and rotate? i ask because im considering not using landscape at all in my app however it would be usefull in a few situations like text entry but is there a way to jump to lanscape without calling oncreate so it will load much faster?
