Orientación de la cámara en Android

Question

Hola amigos. Estoy creando una aplicación para Android que usa código de cámara. He usado android-API 2.1. He instalado mi aplicación en dell mobile y la orientación de la cámara es correcta. Sin embargo, instalé mi aplicación en otros móviles Android como Samsung Galaxy S2, etc. Aquí, el problema es con la orientación de la cámara, incluso en modo retrato, la cámara gira 90 grados. ¿Puede alguien sugerirme si es necesario cambiar los parámetros de la cámara para que la orientación de la cámara funcione bien en todos los móviles ...? Aquí está mi código:

//class CameraDemo 
public class CameraDemo extends Activity { 
private static final String TAG = "CameraDemo"; 
Camera camera; 
Preview preview; 
Button buttonClick; 
Button next; 


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

super.onCreate(savedInstanceState); 
setContentView(R.layout.camdemo); 

preview = new Preview(this); 
((FrameLayout) findViewById(R.id.preview)).addView(preview); 

buttonClick = (Button) findViewById(R.id.buttonClick); 
next = (Button) findViewById(R.id.next); 
buttonClick.setOnClickListener(new OnClickListener() { 
public void onClick(View v) { 

preview.camera.takePicture(shutterCallback, rawCallback, jpegCallback); 

try{ 

Constants.takepic=1; 

buttonClick.setEnabled(false); //once click is clicked, its disable 
} 
catch(Exception e) 
{ 
e.printStackTrace(); 
} 
} 


}); 
next.setOnClickListener(new OnClickListener() { 
public void onClick(View v) { 
//preview.camera.takePicture(shutterCallback, rawCallback, jpegCallback); 
if(Constants.takepic==1) 
{ 
Intent intent_new=new Intent(CameraDemo.this,NotesAndUpload.class); 
startActivity(intent_new); 
} 
else 
{ 
Toast.makeText(CameraDemo.this, "Take a picture",5); 
} 

} 


}); 

Log.d(TAG, "onCreate'd"); 
} 
catch(Exception e){} 
} 


ShutterCallback shutterCallback = new ShutterCallback() { 
public void onShutter() { 
Log.d(TAG, "onShutter'd"); 
} 
}; 

/** Handles data for raw picture */ 
PictureCallback rawCallback = new PictureCallback() { 
public void onPictureTaken(byte[] data, Camera camera) { 
Log.d(TAG, "onPictureTaken - raw"); 
} 
}; 

/** Handles data for jpeg picture */ 
PictureCallback jpegCallback = new PictureCallback() { 
public void onPictureTaken(byte[] data, Camera camera) { 
//taking time and date 
Constants.dateValue=dateAndTime("yyyy-MM-dd"); 
Constants.timeValue=dateAndTime("HH:mm:ss"); 
FileOutputStream outStream = null; 
try { 
// write to local sandbox file system 
// outStream = 
CameraDemo.this.openFileOutput(String.format("%d.j pg", 
System.currentTimeMillis()), 0); 
// Or write to sdcard 
long imageNameLong=System.currentTimeMillis(); 
Constants.imageName=new Long(imageNameLong).toString(); 
outStream = new 
FileOutputStream(String.format("/sdcard/%d.jpg",imageNameLong)); 
outStream.write(data); 
Constants.takepic=1; 
outStream.close(); 

Log.d(TAG, "onPictureTaken - wrote bytes: " + data.length); 
} catch (FileNotFoundException e) { 
e.printStackTrace(); 
} catch (IOException e) { 
e.printStackTrace(); 
} finally { 
} 
Log.d(TAG, "onPictureTaken - jpeg"); 
} 
}; 

} 


//Preview Class 
class Preview extends SurfaceView implements SurfaceHolder.Callback { 
private static final String TAG = "Preview"; 

SurfaceHolder mHolder; 
public Camera camera; 

Preview(Context context) { 
super(context); 

// Install a SurfaceHolder.Callback so we get notified when the 
// underlying surface is created and destroyed. 
mHolder = getHolder(); 
mHolder.addCallback(this); 
mHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BU FFERS); 
} 

public void surfaceCreated(SurfaceHolder holder) { 
// The Surface has been created, acquire the camera and tell it where 
// to draw. 
camera = Camera.open(); 
try { 
camera.setPreviewDisplay(holder); 


camera.setPreviewCallback(new PreviewCallback() { 

public void onPreviewFrame(byte[] data, Camera arg1) {

} catch (FileNotFoundException e) {

e.printStackTrace(); 
} finally { 
}*/ 
Preview.this.invalidate(); 
} 
}); 
} catch (IOException e) { 
e.printStackTrace(); 
} 
} 

public void surfaceDestroyed(SurfaceHolder holder) { 
// Surface will be destroyed when we return, so stop the preview. 
// Because the CameraDevice object is not a shared resource, it's very 
// important to release it when the activity is paused. 
camera.stopPreview(); 
camera = null; 
} 

public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) { 
// Now that the size is known, set up the camera parameters and begin 
// the preview. 
//CAMERA PARAMETERS NEED TO BE CHANGED :- 
Camera.Parameters parameters = camera.getParameters(); 
parameters.setPreviewSize(w, h); 
if(getResources().getConfiguration().orientation == 
Configuration.ORIENTATION_PORTRAIT) 
{ 
parameters.set("rotation",90); 
parameters.set("orientation", "portrait"); 
} 
if (getResources().getConfiguration().orientation == 
Configuration.ORIENTATION_LANDSCAPE) 
{ 
parameters.set("rotation", 90); 
parameters.set("orientation", "landscape"); 

} 
parameters.set("jpeg-quality", 50); 
camera.setParameters(parameters); 
camera.startPreview(); 
} 

@Override 
public void draw(Canvas canvas) { 
super.draw(canvas); 
Paint p= new Paint(Color.RED); 
Log.d(TAG,"draw"); 
canvas.drawText("PREVIEW", canvas.getWidth()/2, canvas.getHeight()/2, p); 
} 
}

Si se le da algún error por favor, publicarlo o utiliza Log.d para mostrar qué parámetros se vuelve su Dell y utilizando SendLog para ver lo que el Samsung Galaxy está volviendo demasiado. Creo que es muy importante verlo, porque tuve algunos problemas con otros parámetros y los resolví así.
