android front and back camera captured picture orientation issue, rotated in a wrong way

Question

I have a camera app in portrait mode which takes pictures from both front and back end cameras.The issue is like the captured images are rotated in a wrong way...

For preview i have used the following code....

    Camera.Parameters parameters = camera.getParameters();
        android.hardware.Camera.CameraInfo info = new android.hardware.Camera.CameraInfo();
        android.hardware.Camera.getCameraInfo(defaultCameraId, info);
        int rotation = this.getWindowManager().getDefaultDisplay()
                .getRotation();
        if (Integer.parseInt(Build.VERSION.SDK) >= 8) {

            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);

        } else {
            parameters.set("orientation", "portrait");
        }

        camera.setParameters(parameters);

But the captured images are rotated in a wrong way.i have also tried to rotate the captured image using matrix.postRotate(bitmap).That too doesn't work in some devices like nexus..I tried EXIF also.But here i have url instead of filepath.That doesn't work as well. can anyone help me ?

Answer 1

You can refer below code.

ExifInterface exif = new ExifInterface(SourceFileName);     //Since API Level 5

String exifOrientation = exif.getAttribute(ExifInterface.TAG_ORIENTATION);

And also refer this link https://stackoverflow.com/a/6124375/1441666

You can use this to get orientation from a Uri

                    String filePath = mImageUri.getPath();
                if (filePath != null) {
                    rotation = -1;
                        ExifInterface exif = new ExifInterface(filePath); // Since
                                                                            // API
                                                                            // Level
                                                                            // 5
                        rotation = Integer.parseInt(exif.getAttribute(ExifInterface.TAG_ORIENTATION));
                        // //Log.v("roation",
                        // exif.getAttribute(ExifInterface.TAG_ORIENTATION));
                    }

                }
            } catch (Exception e) {
                Toast.makeText(getApplicationContext(), "Internal error", Toast.LENGTH_LONG).show();
                Log.e(e.getClass().getName(), e.getMessage(), e);
            }

And as note rotation '3 = 180, 6 = 90, 8 = 270'
