public class AndroidExifActivity extends Activity {
 
 String imagefile ="/sdcard/DCIM/Camera/myphoto.jpg";
 ImageView image;
 TextView Exif;
 
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        image = (ImageView)findViewById(R.id.image);
        Exif = (TextView)findViewById(R.id.exif);
        ImageView image = (ImageView)findViewById(R.id.image);
        
        Bitmap bm = BitmapFactory.decodeFile(imagefile);
        image.setImageBitmap(bm);
        
        Exif.setText(ReadExif(imagefile));
    }
    
    String ReadExif(String file){
     String exif="Exif: " + file;
     try {
   ExifInterface exifInterface = new ExifInterface(file);

   exif += "\nIMAGE_LENGTH: " + exifInterface.getAttribute(ExifInterface.TAG_IMAGE_LENGTH);
   exif += "\nIMAGE_WIDTH: " + exifInterface.getAttribute(ExifInterface.TAG_IMAGE_WIDTH);

   exif += "\n TAG_GPS_LONGITUDE: " + exifInterface.getAttribute(ExifInterface.TAG_GPS_LONGITUDE);
   exif += "\n TAG_GPS_LONGITUDE_REF: " + exifInterface.getAttribute(ExifInterface.TAG_GPS_LONGITUDE_REF);
   exif += "\n TAG_GPS_PROCESSING_METHOD: " + exifInterface.getAttribute(ExifInterface.TAG_GPS_PROCESSING_METHOD);
    
   Toast.makeText(AndroidExifActivity.this, 
     "finished", 
     Toast.LENGTH_LONG).show();
   
  } catch (IOException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
   Toast.makeText(AndroidExifActivity.this,
