Orientation de l'appareil photo sur Android

Question

Bonjour les amis. Je crée une application Android qui utilise le code de la caméra. J'ai utilisé Android-API 2.1. J'ai installé mon application sur dell mobile et l'orientation de la caméra est correcte. Cependant, j'ai installé mon application dans d'autres mobiles android comme Samsung Galaxy S2 etc. Ici, le problème est avec l'orientation de la caméra, même en mode portrait, la caméra est tournée de 90 degrés. Quelqu'un peut-il me suggérer si les paramètres de la caméra doivent être modifiés afin que l'orientation de la caméra fonctionne bien sur tous les mobiles ...? Voici mon code:

//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) { 
/*FileOutputStream outStream = null;

} 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 cela vous donne une erreur s'il vous plaît l'afficher ou utiliser Log.d pour montrer ce que les paramètres retourne votre Dell et en utilisant SendLog pour voir ce qui revient aussi le Samsung Galaxy. Je pense que c'est très important de le voir, parce que j'ai quelques problèmes avec d'autres paramètres et je les ai résolus comme ça.
