 Hi all,

How can I hide some elements present in my spinner, when spinner is
already displated ?

1. Porting Andriod on the Omap3 EVM


I am trying to port android on the Omap3 EVM, but somehow I am facing
problem with kernel build.
For a reference, here I am listed down the steps:

1. Check out the Andriod kernel source code
$mkdir android_2.6.30
$cd android_2.6.30
$git clone git://android.git.kernel.org/kernel/common.git
$git checkout v2.6.30

2. Check out the Omap3 source code
$mkdir linux_2.6.30
$cd linux_2.6.30
$git clone 
$git checkout v2.6.30

3. Take the diff
$diff rN linux_2.6.30 android_2.6.30 > android_patch

4. Apply the anriod patch to omap kernel
$cd linux_2.6.30
$patch 1 <../android_patch

5. Build the kernel

## set the path env
$export PATH=$PATH:/opt/omap3evm/toolchain/arm-2007q3/bin/

## Set to default config
$make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- V=1
(**with this step .config file is created. I found some differences,
when I compared this file with omap3_evm_defconfig. This is very
strange, I couldn understand)

## build the kernel
$make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- V=1 uImage

[I have used default config file map3_evm_defconfigfrom omap git
(mentioned in step2)]

With the above steps, I got following errors while compiling the omap

arm-none-linux-gnueabi-ld -EL  -p --no-undefined -X --build-id -

Can anyone suggest something on this?
Am I doing anything wrong here?

2. Controlling the ProgressBar

I have created a MediaPlayer and will play a sound file. There is also
a ProgressBar which I've configured to be a Horizontal Progress Bar.
The problem I'm having is getting the progress bar to update as the
song plays, i.e. when the song is half way played I want the progress
bar to be half way filled.
I can see that the trick is to use some sort of sleeping thread that
wakes up and then performs the ProgressBar.setProgress
(MediaPlayer.getCurrentPosition()) code but I cannot factor in the
threading code.
Would someone please take a look at a simple version of my code that
uses a button to manually update the progress bar and please help to
set me on the right course. Threads have never been my strong suit :(
Thanks in advance guys.

public class musicPlayer extends Activity {

        private Button buttonPlay;
        private MediaPlayer mp = new MediaPlayer();
        private ProgressBar progressMusic;

        /** Called when the activity is first created. */
    public void onCreate(Bundle savedInstanceState) {


        //Create Play Button
        buttonPlay = (Button) findViewById(R.id.buttonPlay);
        buttonPlay.setOnClickListener(new OnClickListener(){
                public void onClick(View v){

        progressMusic = (ProgressBar) findViewById

        final Button buttonIndex = (Button) findViewById
        buttonIndex.setOnClickListener(new OnClickListener(){
                public void onClick(View v){

    //Creates the player with a default song selected.
    private void initialiseSong(){
        mp = MediaPlayer.create(this, R.raw.cake);
    private void playSong(){
