ImageView does not display image taken from phone camera or photo gallery

I am currently designing an android app that requires at a certain point for the user to select a picture either from the camera or from the phone's gallery. After that I need to display said picture in the activity's image view.

I think the code section that gets the picture is ok, as I can effectively pick the photo from both options. But after that, besides having no picture shown, the src logo of the image view dissapears. I do not understand if I'm doing anything wrong or if there is something missing here, as it is a non-fatal error and the app continues to perform.

So here is my XML layout of the activity:

And the Activity's java(important stuff):

 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_report);
    Spinner spinner = (Spinner) findViewById(R.id.report_type_spinner);
// Create an ArrayAdapter using the string array and a default spinner layout
    ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
            R.array.report_types, android.R.layout.simple_spinner_item);
// Specify the layout to use when the list of choices appears
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
// Apply the adapter to the spinner
    spinner.setAdapter(adapter);
    mReportType = spinner.getItemAtPosition(0).toString();
    spinner.setOnItemSelectedListener(this);
    mDescription = (EditText)findViewById(R.id.description);
    mImageLocationView =(ImageView) findViewById(R.id.imageView);
    Button cameraButton = (Button)findViewById(R.id.camera_button);
    cameraButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            AlertDialog.Builder builder = new AlertDialog.Builder(mContext);
            builder.setTitle(R.string.choose_photo_from)
                    .setItems(R.array.picture_types, new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int which) {
                            // The 'which' argument contains the index position
                            // of the selected item
                            switch(which){
                                case 0: //fotografia
                                    Intent takePicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                                    startActivityForResult(takePicture, 0);
                                    onPause();
                                    //zero can be replaced with any action code
                                    break;
                                case 1:
                                    //galeria

                                            android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

                                    startActivityForResult(pickPhoto , 1);

                            }


                        }
                    });
            builder.create().show();
        }
    });


}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {
    super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
    BitmapFactory.Options o = new BitmapFactory.Options();
    mImageLocationView.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
    switch(requestCode) {
        case 0:
            if(resultCode == RESULT_OK){
                Bitmap photo = (Bitmap) imageReturnedIntent.getExtras().get("data");
                mImageLocationView.setImageBitmap(photo);

            }

            break;
        case 1:
            if(resultCode == RESULT_OK){
                Bitmap photo = (Bitmap) imageReturnedIntent.getExtras().get("data");
                mImageLocationView.setImageBitmap(photo);
            }
            break;
    }

}

I must say, this is my very first android project so I am kind of overwhelmed by so much information and APIS, and also doing a lot of experimenting.
