here the java code is

import android.app.Activity;
import android.content.ContentValues;
import android.content.Intent;
import android.database.Cursor;
import android.media.ExifInterface;
import android.net.Uri;
import android.os.Bundle;
import android.provider.MediaStore;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ImageView;
import android.widget.TextView;

public class MytestdroidActivity extends Activity {

private static final int IMAGE_CAPTURE = 0;
private Button startBtn, upload;
private Uri imageUri;
private ImageView imageView;
private EditText txt;
private TextView tx;
private boolean valid = false;
Float Latitude, Longitude;
EditText location, uploadby, discrip;

 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);

  imageView = (ImageView) findViewById(R.id.img);
  startBtn = (Button) findViewById(R.id.startBtn);
  // tx = (TextView) findViewById(R.id.txt);

  tx = (TextView) findViewById(R.id.txt1);
  // tx.setText(toString());
  startBtn.setOnClickListener(new View.OnClickListener() {
   public void onClick(View v) {
    startCamera();
   }
  });

  upload = (Button) findViewById(R.id.startBtn2);
  upload.setOnClickListener(new OnClickListener() {
   @Override
   public void onClick(View v) {
    // TODO Auto-generated method stub
    // String filename = uristringpic;
    // "mnt/sdcard/DCIM/Camera/1313755630067.jpg";

    try {
     ExifInterface exif = new ExifInterface(
       getRealPathFromURI(imageUri));
     ShowExif(exif);
    } catch (Exception e) {
     System.out.print(e);
    }
   }
  });
 }

 public void startCamera() {
  int imgcounter = 0;

  Log.d("ANDRO_CAMERA", "Starting camera on the phone...");
  String fileName = "testphoto.jpg";
  ContentValues values = new ContentValues();
  values.put(MediaStore.Images.Media.TITLE, fileName);
  values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg");

  imageUri = getContentResolver().insert(
    MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
  Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
  intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
  // intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
  startActivityForResult(intent, IMAGE_CAPTURE);
 }

 public String getRealPathFromURI(Uri contentUri) {
  String[] proj = { MediaStore.Images.Media.DATA };
  Cursor cursor = managedQuery(contentUri, proj, null, null, null);
  int column_index = cursor
    .getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
  cursor.moveToFirst();
  return cursor.getString(column_index);
 }

 private String getTagString(String tag, ExifInterface exif) {
  return (tag + " : " + exif.getAttribute(tag) + "\n");
 }

 protected void onActivityResult(int requestCode, int resultCode, Intent data) {
  if (requestCode == IMAGE_CAPTURE) {
   if (resultCode == RESULT_OK) {
    Log.d("ANDRO_CAMERA", "Picture taken!!!");
    imageView.setImageURI(imageUri);
   }
  }
 }

 private void ShowExif(ExifInterface exif) {
  String myAttribute = "Image Information \n";

  myAttribute += getTagString(ExifInterface.TAG_DATETIME, exif);
  myAttribute += getTagString(ExifInterface.TAG_IMAGE_LENGTH, exif);
  myAttribute += getTagString(ExifInterface.TAG_IMAGE_WIDTH, exif);
  myAttribute += getTagString(ExifInterface.TAG_GPS_LATITUDE, exif);
  myAttribute += getTagString(ExifInterface.TAG_GPS_LATITUDE_REF, exif);
  myAttribute += getTagString(ExifInterface.TAG_GPS_LONGITUDE, exif);
  myAttribute += getTagString(ExifInterface.TAG_GPS_LONGITUDE_REF, exif);
  myAttribute += getTagString(ExifInterface.TAG_FLASH, exif);
  tx.setText(myAttribute);

 }

 @Override
 protected void onResume() {
  try {
   ExifInterface exif = new ExifInterface(getRealPathFromURI(imageUri));
   ShowExif(exif);
  } catch (Exception e) {
   System.out.print(e);
  }
  super.onResume();
 }
}
