Fail to connect to camera service on G1

Question

I apologize in advance for this long post, but it's necessary to show what is happening.

I've been working on an app that works on the 1.6 emulator, but bombs on my G1.

Here is the Photographer activity:

public class Photographer extends Activity {

 private SurfaceView preview = null;
 private SurfaceHolder previewHolder = null;
 private Camera camera = null;
 public static final int IMAGE_HEIGHT = 320;
 public static final int IMAGE_WIDTH = 480;

 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.photographer);

  preview = (SurfaceView)findViewById(R.id.preview);
  previewHolder = preview.getHolder();
  previewHolder.addCallback(surfaceCallback);
  previewHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
 }

 private void takePicture() {
  camera.stopPreview();
  camera.takePicture(null, null, photoCallback);
 }

 SurfaceHolder.Callback surfaceCallback = new SurfaceHolder.Callback() {
  public void surfaceCreated(SurfaceHolder holder) {
   camera = Camera.open();

   try {
    camera.setPreviewDisplay(previewHolder);
   }
   catch (Throwable t) {
    Log.e("Photographer", "Exception in setPreviewDisplay()", t);
   }
   try {
    takePicture();
   } catch (Throwable t) {
    Log.e("Photographer", "Exception in takePicture()", t);
   }
  }

  public void surfaceChanged(SurfaceHolder holder,
         int format, int width, int height) {
   Camera.Parameters parameters=camera.getParameters();
   parameters.setPreviewSize(IMAGE_WIDTH, IMAGE_HEIGHT);
   parameters.setPictureFormat(PixelFormat.JPEG);
   camera.setParameters(parameters);
   camera.startPreview();
  }

  public void surfaceDestroyed(SurfaceHolder holder) {
   camera.stopPreview();
   camera.release();
   camera = null;
  }
 };

 Camera.PictureCallback photoCallback = new Camera.PictureCallback() {
  public void onPictureTaken(byte[] data, Camera camera) {
   new SavePhotoTask().execute(data);
   camera.startPreview();
  }
 };

 class SavePhotoTask extends AsyncTask<byte[], String, String> {
  @Override
  protected String doInBackground(byte[]... jpeg) {
   File photo = new File(Environment.getExternalStorageDirectory(), "WIIA-new.jpg");
   if (photo.exists())
    photo.renameTo(new File(Environment.getExternalStorageDirectory(), "WIIA-old.jpg"));

   try {
    FileOutputStream fos = new FileOutputStream(photo.getPath());

    fos.write(jpeg[0]);
    fos.close();
    Log.e("Photographer", "Picture taken");
    // returning result
      Intent returnIntent = new Intent();
      setResult(RESULT_OK, returnIntent);     
      finish();
   }
   catch (java.io.IOException e) {
    Log.e("Photographer", "Exception in photoCallback", e);

    // returning result
      Intent returnIntent = new Intent();
    setResult(RESULT_CANCELED, returnIntent);
    finish();
   }

   return(null);
  }
 }

}

and here is where this activity gets called from:

    public class WIIA extends Activity {

 public class CountDown extends CountDownTimer {
  private TextView tvCountDown = (TextView) findViewById(R.id.progress);
  private TextView tvSystemState = (TextView) findViewById(R.id.system_state);

  public CountDown(long millisInFuture, long countDownInterval) {
   super(millisInFuture, countDownInterval);
  }

  @Override
  public void onFinish() {
   tvSystemState.setText(R.string.system_state_armed);
   tvCountDown.setText(R.string.armed);
   snapshotInterval = Long.parseLong(settings.getString("snapshot_interval_list", "5"));
   imgCaptureTimer = new Timer("imageCapture");
   imgCaptureTimer.scheduleAtFixedRate(doRefresh, 0, snapshotInterval*1000);
  }

  @Override
  public void onTick(long millisUntilFinished) {
   tvCountDown.setText(millisUntilFinished/1000 + " seconds until Armed");
  }

 }

 private TimerTask doRefresh = new TimerTask() {
  public void run() {
   if (armed) {
    refreshImage();
   } else {
    imgCaptureTimer.cancel();
   }
  }
 };

 private void refreshImage() {
  Thread updateThread = new Thread(null, backgroundCaptureImage, "capture_image");  
  updateThread.start();        
 }

 private Runnable backgroundCaptureImage = new Runnable() {
  public void run() {
   doRefreshImage();
  }        
 };

 private void doRefreshImage() {
  Intent photographer = new Intent(this, Photographer.class);
  startActivityForResult(photographer, GET_PHOTO);
 }

 @Override
 public void onActivityResult(int requestCode, int resultCode, Intent data) {
  super.onActivityResult(requestCode, resultCode, data);
  switch(requestCode) {
   case (GET_PHOTO) : {
    if(resultCode == RESULT_OK) {
    // go on to compare images
     new ProcessImageTask().execute();
    }
    break;
   }
  }
 }

Having trouble pasting the relevant portions of AndroidManifest.xml, but I have permissions for Camera:

  <uses-permission android:name="android.permission.CAMERA" />

here's the Photographer part:

      <activity android:name=".Photographer"
   android:configChanges="keyboardHidden|orientation"
   android:screenOrientation="landscape"
   android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
  </activity>

also set for testing on G1:

android:debuggable="true"

and working off of 1.6:

<uses-sdk android:minSdkVersion="4" />

All this works on a 1.6 emulator, but when I run this on the G1, LogCat shows:

It sounds like the problem is a timeout issue, but I am at a loss as to where I should be looking .... does anyone have a clue?

Thanks!

Answer 1

Most probably the cameraService which is part of the media process has crashed in the background. If you just try to run the default camera app in android and it does not show up then simply reboot the device to get this error off.

Answer 2

Try to define the permission tag outside the application tag, like this:

<manifest ......>
    <uses-permission android:name="android.permission.CAMERA" />
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity ...
                  .....>
        </application>
</manifest>

Answer 3

You should not call stopPreview prior to takePicture.

http://developer.android.com/reference/android/hardware/Camera.html

6.Important: Call startPreview() to start updating the preview surface. Preview must be started before you can take a picture.

 private void takePicture() {
  // WRONG: camera.stopPreview();
  camera.takePicture(null, null, photoCallback);
 }
