 I am trying to pass a simple string in to a new activity.  I feel a
little dense.  I have looked at the samples, and I just can't seem to
get it through my thick head.  What do I need in the first parameter.

        public static final String DRINK_TYPE = "type";
.
.
.
        Intent i = new Intent(this, BeerScreen.class);
        i.putExtra(DRINK_TYPE, "beer");


Then in BeerScreen.java

        String sType = extras.getString("type");
        if(sType == "beer"){

The code inside the if is not executed.  <sigh>

Kevin

 Dude,
Use Java functions equals or compareTo, "==" operator won't work

Cheers,
Tej

 Hi,

if you have static final String DRINK_TYPE you can use follow construct

if(className.DRINK_TYPE.equals("beer")){
}

or make new class just with constats
class IConstants
...
public static final String DRINK_TYPE = "type";
public static final String  BEER = "beer";
public static final String LAGER = "lager";
...


and next
if(IConstants.DRINK_TYPE.equals(IConstants.BEER)){
...
}

1. Unable to prepare VideoCamera to capture videos

Hello,
Does anyone know how to capture videos with Android VideoRecoder?

I am trying to develop an application that I could use to capture
video. I am
trying to use the MediaRecorder API in 1.5, which is supposed to
support
video capture. However,  I got an error report from prepare() method.
Here are
the initializeVideo settings and the logcat shows:

PS: In order to fix the problem, I suppress the audio recording. And
my sdcard is enabled in the phone.
Thanks for your help!

in packages\apps\Camera\src\com\android\camera\VideoCamera.java

in method initializeVideo

       mMediaRecorder = new MediaRecorder();

        if (DEBUG_SUPPRESS_AUDIO_RECORDING) {
            Log.v(TAG, "DEBUG_SUPPRESS_AUDIO_RECORDING is true."); //
this will be done!
        } else {
            mMediaRecorder.setAudioSource
(MediaRecorder.AudioSource.MIC);
        }
        mMediaRecorder.setVideoSource
(MediaRecorder.VideoSource.CAMERA);

        mMediaRecorder.setOutputFormat
(MediaRecorder.OutputFormat.MPEG_4);

        mMediaRecorder.setMaxDuration(MAX_RECORDING_DURATION_MS);

        if (mStorageStatus != STORAGE_STATUS_OK) {
            mMediaRecorder.setOutputFile("/dev/null");
        } else {
            // We try Uri in intent first. If it doesn't work, use our
own instead.
            if (mCameraVideoFileDescriptor != null) {
                mMediaRecorder.setOutputFile
(mCameraVideoFileDescriptor);
            } else {
                createVideoPath();
                mMediaRecorder.setOutputFile(mCameraVideoFilename);
            }
        }

        boolean videoQualityHigh = getBooleanPreference
(CameraSettings.KEY_VIDEO_QUALITY,
                CameraSettings.DEFAULT_VIDEO_QUALITY_VALUE);

        if (intent.hasExtra(MediaStore.EXTRA_VIDEO_QUALITY)) {
            int extraVideoQuality = intent.getIntExtra
(MediaStore.EXTRA_VIDEO_QUALITY, 0);
            videoQualityHigh = (extraVideoQuality > 0);
        }
        mMediaRecorder.setVideoFrameRate(15);
        if (videoQualityHigh) {
            mMediaRecorder.setVideoSize(320,240);
        } else {
            mMediaRecorder.setVideoSize(176,144);
        }
        mMediaRecorder.setVideoEncoder
(MediaRecorder.VideoEncoder.MPEG_4_SP);
        if (!DEBUG_SUPPRESS_AUDIO_RECORDING) {
            mMediaRecorder.setAudioEncoder
(MediaRecorder.AudioEncoder.AMR_NB);
        }
        mMediaRecorder.setPreviewDisplay(mSurfaceHolder.getSurface());

        long remaining = getAvailableStorage();

        try {
            mMediaRecorder.setMaxFileSize(remaining -
LOW_STORAGE_THRESHOLD / 4);
        } catch (RuntimeException exception) {

        }

        try {
            mMediaRecorder.prepare();
        } catch (IOException exception) {
            Log.e(TAG, "prepare failed for " + mCameraVideoFilename);
            releaseMediaRecorder();
            return false;
        }
        mMediaRecorderRecording = false;

        if (!mIsVideoCaptureIntent && !mThumbController.isUriValid())
{
            updateLastVideo();
        }

        if (!mIsVideoCaptureIntent) {
            mThumbController.updateDisplayIfNeeded();
        }

        return true;
