Android programming - Phone Number Utility

Click button utk buat call.

Ini adalah salah satu fungsi dalam app Kad Jemputan aku. Tapi source code Kad Jemputan aku dah hilang :(. Jadi aku kena cari semula semua fungsi2 yang aku guna untuk Kad Jemputan.

Salah satu fungsi yang aku guna adalah Phone Utility.

Dari android studio, aku create New Project. Aku guna default source code yang Android Studio generate iaitu "Hello World". Menggunakan source code yang sama, aku tambah beberapa command line untuk Phone Utility. Semua command yg aku tambah di highlighted dengan warna kuning.

Moga2 ini akan menjadi rujukan aku masa depan & sapa-sapa yang memerlukan. Somoga ada manfaat.



Ada 3 file ni.
