Apps Taking an Image and Saving it to the Camera Roll

[someguysomewhere]

First off, I just started experimenting with writing Android apps for about the last week, so I'm still very much a noob at this.

The problem I'm having is I've written a camera type app that takes an image, using the Android devices built in camera, then sends a display of the image back to the app. It worked fine until I wanted to save the image automatically to the devices camera roll after taking the image. I put in this code and now it wont display the image back into the app like before:

File file = new File(Environment.getExternalStorageDirectory(), CurrentDateAndTime + ".jpg");
Uri photoPath = Uri.fromFile(file);
intent.putExtra(MediaStore.EXTRA_OUTPUT, photoPath);

Here is the whole MainActivity.java file:

package com.example.camera;
 
import java.io.File;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.List;
 
import android.net.Uri;
import android.os.Bundle;
import android.os.Environment;
import android.provider.MediaStore;
import android.app.Activity;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.content.pm.ResolveInfo;
import android.graphics.Bitmap;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TextView;
 
public class MainActivity extends Activity implements OnClickListener {
 
    Button btnTackPic;
    ImageView ivThumbnailPhoto;
    Bitmap bitMap;
    static int TAKE_PICTURE = 1;
    String CurrentDateAndTime= getCurrentDateAndTime();
 
    @Override
    protected void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
 
        btnTackPic = (Button) findViewById(R.id.btnTakePic);
        ivThumbnailPhoto = (ImageView) findViewById(R.id.ivThumbnailPhoto);
 
        btnTackPic.setOnClickListener(this);
    }
 
    private String getCurrentDateAndTime() 
    {
        Calendar c = Calendar.getInstance();
        SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd-HH-mm-ss");
        String formattedDate = df.format(c.getTime());
        return formattedDate;
    }

    @Override
    public void onClick(View view) 
    {
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

        File file = new File(Environment.getExternalStorageDirectory(), CurrentDateAndTime + ".jpg");
        Uri photoPath = Uri.fromFile(file);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, photoPath);
        
        startActivityForResult(intent, TAKE_PICTURE);
    }
 
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent intent) 
    {
        if (requestCode == TAKE_PICTURE && resultCode== RESULT_OK && intent != null)
        {
            Bundle extras = intent.getExtras();
 
            bitMap = (Bitmap) extras.get("data");
            
            ivThumbnailPhoto.setImageBitmap(bitMap);
        }
    }
}

Does it have to do with EXTRA_OUTPUT returning a null value?
