Unable to retrieve captured image from camera

Question

I am building a simple camera application in android, which would launch a camera intent on click of a button. The camera intent would then click an image which would later be displayed in the ImageView present in the MainActivity. The issue however is that I am able to capture the image but as soon as the image is captured instead of displaying the image the app suddenly crashes.

Here is my code for the app:

MainActivity.java

package com.example.suzancruz.cameraapplicaton;

import android.content.Intent;
import android.graphics.Bitmap;
import android.provider.MediaStore;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;


public class MainActivity extends AppCompatActivity {


    static final int REQUEST_IMAGE_CAPTURE = 123;
    ImageView myImageView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

    }

    //Launching the camera
    public void launchCamera(View view){
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        //Take a picture and pass results along to onActivityResult
        startActivityForResult(intent, REQUEST_IMAGE_CAPTURE);
    }

    //If you want to return the image taken
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if(requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK){
            //Get the photo
            Bundle extras = data.getExtras();
            Bitmap photo = (Bitmap) extras.get("data");
            myImageView.setImageBitmap(photo);
        }
    }
}

try this `public void onTakeImg() {

        startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
