Hi,
I'm trying to retrieve Latitude/Longitude informations of an image,
but I always get 0.0 for lat/lon.
But I know the image has this information inside, because I tried it
with exiftools. When I use exiftools I can see the lat/lon values.
My Source:
startActivity:
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("image/*");
startActivityForResult(intent, 1);
and onActivtiyResult
Uri photoUri = data.getData();
ContentResolver cr = getContentResolver();
Cursor cursor = cr.query(photoUri, new String[] {
MediaStore.Images.ImageColumns.DATA,
MediaStore.Images.ImageColumns.LATITUDE,
MediaStore.Images.ImageColumns.LONGITUDE },
null, null, null);
cursor.moveToFirst();
int fnamecol = cursor.getColumnIndexOrThrow
(Images.ImageColumns.DATA);
int latcol = cursor.getColumnIndexOrThrow
(Images.ImageColumns.LATITUDE);
int loncol = cursor
.getColumnIndexOrThrow(Images.ImageColumns.LONGITUDE);
String fname = cursor.getString(fnamecol);
Float lat = cursor.getFloat(latcol);
Float lon = cursor.getFloat(loncol);
This should work, because I get the filename, or is this a total
wrong approach?
Regards Georg
