APLIKASI GO-COURSE BERBASIS ANDROID DENGAN
MENGGUNAKAN METODE LOCATION BASE SERVICE
adalah aplikasi yang dibuat menggunakan bahasa pemrograman Android Studio,
Flutter dan database MySQL. Aplikasi yang mempermudah pengguna untuk lebih
mengetahui tentang Pare Kampung Inggris. Aplikasi ini menampilkan informasi
tentang Pare Kampung Inggris yang digunakan untuk wadah pencarian kursusan,
kos, camp serta rental kendaraan.

Berikut Tutorial Penggunaannya:
1. Tampilan masuk Aplikasi
Tampilan sebelum masuk ke menu utama pada apliksai Go-Course Pare
seperti pada gambar dibawa ini.
4

5. Button Navigasi dan Hubungi Pemilik Go-Course Pare
Pada bagian ini pengguna dapat mengetahui letak tempat yang dituju dari
titik awal user berada dan dapat menghubungi pemilik tempat melalui WhatsApp
seperti pada gambar di bawah ini.
Demikian proses yang dapat dijelaskan dari Aplikasi GO-COURSE Berbasis
Android dengan Menggunakan Metode Location Base Service
