cara menempatkan geopoint dari lokasi pengguna saat ini di parse.com

Jadi saya baru mengenal pemrograman database dan juga pemrograman Android, saya mencoba mendapatkan lokasi pengguna dan menyimpan lokasi tersebut ke dalam database parse.com. Saya yakin kode saya berada di jalur yang benar, dapatkah seseorang membantu saya mengatasi masalah ini?
