onActivityResult returns null Intent

I am trying to capture image from camera. But it returns null Intent onActivityResult . Here is my code

CaptureImageFromCamera.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
        startActivityForResult(intent, 7);
    }
});

And onActivityResult is 

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == 7 && resultCode == RESULT_OK) {
        try {
            if(data.getData() == null) {
                bitmap = (Bitmap)data.getExtras().get("data");
            } else {
                bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), data.getData());
            }

            ImageViewHolder.setImageBitmap(bitmap);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

I am new to Android so please explain answer in detail. Thanks in advance..!

Uri imageUri = data.getData() will no more work.. first get bitmap from data like this:

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
        val imageBitmap = data.extras.get("data") as Bitmap
        imageView.setImageBitmap(imageBitmap)
    }
}

then save bitmap image.. please find details here:

You can also use setImageURI() in onActivityResult() instead of setImageBitmap()

First of all add the camera permissions in android manifest. If your android version is greater than lollipop then you need to add run time permissions See documentations here

<uses-permission android:name="android.permission.CAMERA"/>

and then your code will be 

CaptureImageFromCamera.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
        startActivityForResult(intent, 7);
    }
});

and then use setImageUrI() in your onActivityResult()

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

     switch (requestCode)
        {
            case 7:
                /*case 7 for image results and display image in imageview via Uri*/
                if (resultCode == RESULT_OK)
                {
                    Uri imageUri = data.getData();
                    ImageViewHolder.setImageURI(imageUri);
                }
                return;
           default:
                return;
        }
}

Make sure you have added camera permissions, write permissions in manifest and also cross verify run time permissions.

Use your Intent like below, and specify the path where captured image will be write -

   intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);

   Uri outputUri = Uri.fromFile("path of your directory");
   intent.putExtra(MediaStore.EXTRA_OUTPUT, outputUri);

   startActivityForResult(intent, 7);

Start Your work by passing intent through this : 

startActivityForResult(new Intent(MediaStore.ACTION_IMAGE_CAPTURE), 100);

so after capturing the image from camera use to get data about images through intent :

 protected void onActivityResult(int requestCode, int resultCode, Intent data) {
     Uri yourCapturedImage = intent.getData();
 }
