How to convert content:// Uri into actual file path?

Question

how can I get the actual file path on the SD card where a content:// uri is pointing for an image?

Answer 1

I've adapted the code which @hooked82 linked to:

protected String convertMediaUriToPath(Uri uri) {
    String [] proj={MediaStore.Images.Media.DATA};
    Cursor cursor = getContentResolver().query(uri, proj,  null, null, null);
    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    String path = cursor.getString(column_index); 
    cursor.close();
    return path;
}
