Android Camera opens in landscape mode orientation for front camera in openCV\javaCV [closed]

edit

I made an app for opening a front camera in my android phone. The problem is it always opens the camera but the image shown is in landscape mode only.

So irrespective of I am holding the phone right direction , I am getting 90 degree of orientation difference.

How to sort out this problem. Layout-

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_height="fill_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".AppLockMainActivity" >

<!-- <ImageView
    android:id="@+id/myImageView"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:src="@drawable/bol" />-->

  <org.opencv.android.NativeCameraView
        android:layout_width="fill_parent"
        android:layout_height="match_parent"

        opencv:camera_id="front" />
