Not getting orientation by using OrientationEventListener in android

I need to detect an orientation of an device, for that I have written a code below. But I am unable get orientation.This is my oncreate() in MainActivity... If i need to change anything please let me know

protected void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);

    mOrientationListener = new OrientationEventListener(getApplicationContext()) 
    {
        @Override
        public void onOrientationChanged(int orientation) 
        {
            if(orientation == 0)
            {
                setContentView(R.layout.activity_main_portrait);
            }
            else
            {
                setContentView(R.layout.activity_main_landscape);
            }
        }
    };
    if (mOrientationListener.canDetectOrientation()) 
    {          
        mOrientationListener.enable();
    }

    mImgPreview = (ImageView) findViewById(R.id.imgpreview);
    mVideoPreview = (ImageView) findViewById(R.id.videopreview);
    mAudioPreview = (ImageView) findViewById(R.id.audiopreview);

    /*-------Intent to view Image Gallery---------*/
    mImgPreview.setOnClickListener(new OnClickListener() 
    {
        @Override
        public void onClick(View v) 
        {
            Intent intent = new Intent(getApplicationContext(), ImageList.class);
            startActivity(intent);
        }
    });

    /*-------Intent to view Video Gallery---------*/
    mVideoPreview.setOnClickListener(new OnClickListener() 
    {
        @Override
        public void onClick(View v) 
        {
            Intent intent = new Intent(getApplicationContext(), Video.class);
            startActivity(intent);
        }
    });

    /*--------Intent to view Audio Gallery--------*/
    mAudioPreview.setOnClickListener(new OnClickListener() 
    {

        @Override
        public void onClick(View v) 
        {
            Intent intent = new Intent(getApplicationContext(), AudioPlayer.class);
            startActivity(intent);
        }
    });
}

check your AndroidManifest, your main activity(entrance of your app) should be set with

android:exported="true"

this is not necessary with sdk 28, but somehow the listener will not work if exported is not set ; Also you can check your logcat while running app, in my condition

"Tried enabling a sensor (lsm6dso Accelerometer Non-wakeup) without hold"

can be found in logcat everytime running the activity with orientationEventListener.

You need to enable the listener to make it work.

OrientationEventListener mOrientationListener = new OrientationEventListener(
                getApplicationContext()) {
    @Override
    public void onOrientationChanged(int orientation) {
        if (orientation == 0 || orientation == 180) {
            Toast.makeText(getApplicationContext(), "portrait",
                            Toast.LENGTH_LONG).show();
        } else if (orientation == 90 || orientation == 270) {
            Toast.makeText(getApplicationContext(), "landscape",
                            Toast.LENGTH_LONG).show();
        }
    }
};

if (mOrientationListener.canDetectOrientation()) {          
    mOrientationListener.enable();
}

This is working fine for me.

Hope it helps.

use this....

 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);

  Configuration config = getResources().getConfiguration();

  if (config.orientation == Configuration.ORIENTATION_LANDSCAPE) {
             // setContentView 1 here
  }else{
             // setContentView 2 here
  }

}

write this code in the onCreate() function coz the Activity starts its cycle from starting during change in the orientation..
