picture GPS coordinates [resolved]

beran · by **beran** » Sat Dec 05, 2009 9:39 pm

Hi!

I’m designing my first Android Application.

The goal of this application is to order automatically the mobile pictures.

I would like to use the GPS coordinates of the pictures stocked in the sdcard.

Is there any way to access the GPS coordinates of the pictures took with the camera application?

(Excuse my bad English)
Thanks a lot!

Thanks Glimax !

It really helped me !

I tried this code :

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

int latitude = 0;
 
ArrayList<Double> latitudeList = new ArrayList<Double>();
 
latitude = SystemInformation.cursor.getColumnIndexOrThrow(MediaStore.Images.ImageColumns.LATITUDE);
 
if (SystemInformation.cursor.moveToFirst()) {
                        do {
                                …
                                latitudeList.add(SystemInformation.cursor.getDouble(latitude));
                        } while (SystemInformation.cursor.moveToNext());
 
…
globalList.add(latitudeList);
}
 
Parsed in 0.046 seconds,  using GeSHi 1.0.8.4

It doesn’t works… I have an exception because the system don’t find the latitude column.
I’m not sure that the native camera application saves GPS data.

The following code works for me....

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

TextView tv=(TextView)findViewById(R.id.results);
        
        String[] proj={Media.LATITUDE,Media.LONGITUDE}; // from android.provider.MediaStore.Images.Media
        
        Uri images=Media.EXTERNAL_CONTENT_URI;
        
        Cursor cur=managedQuery(images, proj, null, null, null);
        
        tv.append("Number of results: "+cur.getCount()+"n");
        if (cur.moveToFirst()) {
 
            int latCol = cur.getColumnIndex(Media.LATITUDE); 
            int lonCol = cur.getColumnIndex(Media.LONGITUDE);
             
            do {
                
                double lat = cur.getDouble(latCol);
                double lon = cur.getDouble(lonCol);
                tv.append(""+lat+" ; "+lon+"n");
               
            } while (cur.moveToNext());
 
        }
Parsed in 0.068 seconds,  using GeSHi 1.0.8.4

on the emulator i have take 3 shots.

and the result is that:

Code: Select all: Number of results:3 0.0 ; 0.0 0.0 ; 0.0 0.0 ; 0.0

so, basically it works...

let me know.
