J'essaie d'aller chercher l'emplacement de l'image capturée de la caméra. Quand j'ai essayé une interface Exif mais revenir encore une valeur nulle de quelqu'un photos.Please aider ...

Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); 
          startActivityForResult(i, 100); 
    @Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 
    if (requestCode == 100 && resultCode == RESULT_OK && data != null) { 
     // Let's read picked image data - its URI 
     Uri pickedImage = data.getData(); 
     // Let's read picked image path using content resolver 
     String[] filePath = {MediaStore.Images.Media.DATA}; 
     Cursor cursor = getContentResolver().query(pickedImage, filePath, null, null, null); 
     cursor.moveToFirst(); 
     img1 = cursor.getString(cursor.getColumnIndex(filePath[0])); 


     ExifInterface exif = null; 
     try { 
      exif = new ExifInterface(img1); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
     String lat = ExifInterface.TAG_GPS_LATITUDE; 
      String lat_data = exif.getAttribute(lat); 
      Log.e("MYDATA", lat_data); 
      cursor.close(); 
      Toast.makeText(this, "Image Uploaded", Toast.LENGTH_SHORT).show();

Utilisez résolveur contenu pour construire ExifInterface avec fluxEntrée

@Override 
    public void onActivityResult(int requestCode, int resultCode, Intent intent) { 
     super.onActivityResult(requestCode, resultCode, intent); 
     if (resultCode != Activity.RESULT_OK) { 
      return; 
     } 
     final Uri originalUri = intent.getData(); 

     try { 
      final InputStream inputStream = getContext().getContentResolver().openInputStream(originalUri); 
      final android.support.media.ExifInterface exif = new android.support.media.ExifInterface(inputStream); 
      final double[] latLong = exif.getLatLong(); 
      Log.v(LOG_TAG, "Image selected at position: " + latLong[0] + " : " + latLong[1]); 

     } catch (IOException e) { 
      Log.w(LOG_TAG, "Error when getting location from image", e); 
     } 
    }
