Android Camera setDisplayOrientation does not work

Question

i am working camera project in android.my problem is camera setDisplayOrientation method is not working and my camera preview on surface always landscape.i want to expected portrait camera preview on SurfaceView. I am using Samsung galaxy y (Android 2.3.5) and my activity code shown below:

import java.io.IOException;

import android.app.Activity;
import android.graphics.PixelFormat;
import android.hardware.Camera;
import android.os.Bundle;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
import android.view.View;
import android.widget.Button;

public class AndroidCamera extends Activity implements SurfaceHolder.Callback{

 Camera camera;
 SurfaceView surfaceView;
 SurfaceHolder surfaceHolder;
 boolean previewing = false;;

 String stringPath = "/sdcard/samplevideo.3gp";

   /** Called when the activity is first created. */
   @Override
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.main);

       Button buttonStartCameraPreview = (Button)findViewById(R.id.startcamerapreview);
       Button buttonStopCameraPreview = (Button)findViewById(R.id.stopcamerapreview);

       getWindow().setFormat(PixelFormat.UNKNOWN);
       surfaceView = (SurfaceView)findViewById(R.id.surfaceview);
       surfaceHolder = surfaceView.getHolder();
       surfaceHolder.addCallback(this);
       surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);

       buttonStartCameraPreview.setOnClickListener(new Button.OnClickListener(){

   @Override
   public void onClick(View v) {
    // TODO Auto-generated method stub
    if(!previewing){
     camera = Camera.open();
     if (camera != null){
      try {
       camera.setDisplayOrientation(90);
       camera.setPreviewDisplay(surfaceHolder);
       camera.startPreview();
       previewing = true;
      } catch (IOException e) {
       // TODO Auto-generated catch block
       e.printStackTrace();
      }
     }
    }
   }});

       buttonStopCameraPreview.setOnClickListener(new Button.OnClickListener(){

   @Override
   public void onClick(View v) {
    // TODO Auto-generated method stub
    if(camera != null && previewing){
     camera.stopPreview();
     camera.release();
     camera = null;

     previewing = false;
    }
   }});

   }



 @Override
 public void surfaceChanged(SurfaceHolder holder, int format, int width,
   int height) {
  // TODO Auto-generated method stub

 }

 @Override
 public void surfaceCreated(SurfaceHolder holder) {
  // TODO Auto-generated method stub

 }

 @Override
 public void surfaceDestroyed(SurfaceHolder holder) {
  // TODO Auto-generated method stub

 }
}

my problem shown blow figure:

enter image description here

Any one can help with any code or tutorial links and thanks for spending valuable your time

is it working on other phones??? or have you tried only with this one?? — sheetal, Feb 28 '13 at 08:18

Finally i got solution and find camera preview surface view following code:

        // Install a SurfaceHolder.Callback so we get notified when the
        // underlying surface is created and destroyed.

        mHolder.addCallback(this);
        // deprecated setting, but required on Android versions prior to 3.0

    protected void configureCameraParameters(Camera.Parameters cameraParams, boolean portrait) {
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.FROYO) { // for 2.1 and before

        cameraParams.setPreviewSize(mPreviewSize.width, mPreviewSize.height);

        }

        mCamera.setParameters(cameraParams);
    }


    public boolean isPortrait() {
        return (mActivity.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT);
    }
}

It's need minimum sdk 2.3 or higher

if you want to rotate the preview output, try this:

public void surfaceChanged(SurfaceHolder holder, int format, int width, int height)
    {            
        if (isPreviewRunning)
        {
            mCamera.stopPreview();
        }

        Parameters parameters = mCamera.getParameters();
        Display display = ((WindowManager)getSystemService(WINDOW_SERVICE)).getDefaultDisplay();

        if(display.getRotation() == Surface.ROTATION_0)
        {
            parameters.setPreviewSize(height, width);                           
            mCamera.setDisplayOrientation(90);
        }

        if(display.getRotation() == Surface.ROTATION_90)
        {
            parameters.setPreviewSize(width, height);                           
        }

        if(display.getRotation() == Surface.ROTATION_180)
        {
            parameters.setPreviewSize(height, width);               
        }

        if(display.getRotation() == Surface.ROTATION_270)
        {
            parameters.setPreviewSize(width, height);
            mCamera.setDisplayOrientation(180);
        }

        mCamera.setParameters(parameters);
        previewCamera();                      
    }

For lower API levels you could use:

private void setCameraDisplayOrientationAPI8(){
        //Sets the camera right Orientation.
        //Special void for API 8 build.
        //This void should be called before calling camera.setParameters(cameraParameters).
        if (activeActivity.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT)
        {   
            camera.setDisplayOrientation(90);
        }
        if (activeActivity.getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE)
        {                               
            camera.setDisplayOrientation(180);
        }
    }

and just call setCameraDisplayOrientationAPI8(); on your surfaceChanged func.

plus:

private void setCameraDisplayOrientation() {
        //Sets the camera right Orientation.
        //IMPORTANT!! This code is available only for API Level 9 build or greater.
        if (mApiLvl<9){
            Log.d(TAG, "setCameraDisplayOrientation ERROR: This code is available only for API Level 9 build or greater.");
            return;
        }
        android.hardware.Camera.CameraInfo info =
                new android.hardware.Camera.CameraInfo();
        android.hardware.Camera.getCameraInfo(cameraIndex, info);
        int rotation = activeActivity.getWindowManager().getDefaultDisplay()
                .getRotation();
        int degrees = 0;
        switch (rotation) {
            case Surface.ROTATION_0: degrees = 0; break;
            case Surface.ROTATION_90: degrees = 90; break;
            case Surface.ROTATION_180: degrees = 180; break;
            case Surface.ROTATION_270: degrees = 270; break;
        }

        int result;
        if (info.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
            result = (info.orientation + degrees) % 360;
            result = (360 - result) % 360;  // compensate the mirror
        } else {  // back-facing
            result = (info.orientation - degrees + 360) % 360;
        }
        camera.setDisplayOrientation(result);
    }

hope this helps.

Also, check if the "Auto-rotate Screen" option is checked in the phone Settings (Settings > Dislay or Screen - depends on the android version).

It took me quite a while till a figured it out. If it's not checked, the orientation of the camera in the app may be ignored.
