Getting the file path from a picture in ImageView

Alright I am making an Android app, and using the CAPTURE_PIC_REQUEST to take a picture and store it as a preview on the screen in an imageviewer. I wanted to know how to get the Uri and actually path because I am planning on taking that information, saving it and accessing it later. So I can't figure how to get the Uri or path name from that picture I just took. Here is the code from my activity that is handling 

package com.CS480;

import java.io.File;

import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;

public class AddEx extends Activity {
  static final int CAMERA_PIC_REQUEST = 1337; 
  public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.add);

    Button camera = (Button) findViewById(R.id.picButton);
    camera.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {
            Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
            startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);               
        }               
    });

}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == CAMERA_PIC_REQUEST) {  
        Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
        ImageView image = (ImageView) findViewById(R.id.returnedPic);  
        image.setImageBitmap(thumbnail);  
    }  
}

}

So how from that image that I am getting back on the app do I get the file location

Try this get image file path form Bitmap

public void uploadBitmap(Context mContext, Bitmap bitmap) {

    String imagePath = null;
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
    Uri uri;
    Cursor cursor = mContext.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, new String[]{MediaStore.Images.Media.DATA, MediaStore.Images.Media.DATE_ADDED, MediaStore.Images.ImageColumns.ORIENTATION}, MediaStore.Images.Media.DATE_ADDED, null, "date_added DESC");
    if (cursor != null && cursor.moveToFirst()) {
        do {
            uri = Uri.parse(cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA)));
            imagePath = uri.toString();
            Log.d("pathatka", uri.toString());
            break;
        } while (cursor.moveToNext());
        cursor.close();
    }

}

The android documentation has an example of defining a file URI for saving the output when you setup the Intent for your image capture.

As far as I know, you can do something like this:

private Uri mImageCaptureUri;

public class AddEx extends Activity {
  static final int CAMERA_PIC_REQUEST = 1337; 
  public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.add);

    Button camera = (Button) findViewById(R.id.picButton);
    camera.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {
            Intent cameraIntent = 
                    new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
            cameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT,
                    mImageCaptureUri);
            startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);               
        }               
    });

}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == CAMERA_PIC_REQUEST) {  
        Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
        ImageView image = (ImageView) findViewById(R.id.returnedPic);  
        image.setImageBitmap(thumbnail);  

        String pathToImage = mImageCaptureUri.getPath();

        // pathToImage is a path you need. 

        // If image file is not in there, 
        //  you can save it yourself manually with this code:
        File file = new File(mImageCaptureUri.getPath());
        FileOutputStream fOut = new FileOutputStream(file);
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fOut); // You can choose any format you want
    }  
}

From Android documentation about android.provider.MediaStore.EXTRA_OUTPUT:

The name of the Intent-extra used to indicate a content resolver Uri to be used to store the requested image or video.

When you take your image, you must store it somewhere to get the location of the image.

To do this, you can store to the MediaStore:

String result = MediaStore.Images.Media.insertImage(getContentResolver(), bitmap, "", "");

imageFileUri = Uri.parse(result);

You can try getting the URI of the image with 

data.getExtras.get("URI");

but this might not work. What you can do is simply save the Bitmap yourself. See this question for a guide on how to do that: Save bitmap to location
