MEMULAI PROGRAM ANDROIDBerikut ini, kita akan membuat sebuah aplikasi program GoSIP sederhana berbasis mobile dengan SUNJAVA.
Alat dan Bahan :
- Sun Java (TM) Wireless Toolkit 2.5.2_01 for CLDC atau bisa gunakan yang lainnya. Untuk menginstallnya, kita harus install dulu jdk.
- Notepad++.
Langkah – Langkah :
- Kita jalankan dulu Sun Java (TM) Wireless Toolkit 2.5.2_01 for CLDC. Setelah itu, klik New Project, di ProjectName kita ketikkan nama project kita, misalnya AplikasiNilai, di MIDlet Class Name ketikkan tulisan yang sama, Lalu klik Create Project.
Selanjutnya akan muncul kotak dialog setting, kita klik OK saja. Setelah itu akan tampil tulisan
Creating project "Hadi_GS"Place Java source files in " C:\MyDocuments\ Java\j2mewtk\252\apps\Hadi_GS \src"Ket: Disinilah tempat kita menyimpan source atau koding program yang kita buat yaitu pada direktori SRC
Place Aplication resource files in " C:\MyDocuments\ Java\j2mewtk\252\apps\Hadi_GS \res"Ket: Disinilah tempat kita menyimpan file gambar atau animasi yang kita buat yaitu pada direktori RES
Place Aplication library files in " C:\MyDocuments\ Java\j2mewtk\252\apps\Hadi_GS \lib"Ket: Disinilah tempat kita menyimpan file fungsi yang kita buat yaitu pada direktori LIB
2. Kita buka notepad++ atau aplikasi notepad yang anda punya, ketikkan source code berikut:

Selanjutnya Kita kembali lagi ke Sun Java (TM) Wireless Toolkit 2.5.2_01 for CLDC.
3. Di sini, kita klik Build untuk mengetahui apakah program yang kita buat sudah benar atau belum. Jika masih terdapat kesalahan maka perhatikan kesalahannya pada baris kesalahan dan lokasi kesalahan yang ditunjukan pada layar konsul. Perbaiki kesalahan program tersebut hingga selesai simpan dan ulangi Build kembali. Setelah proses build selesai jika tidak terdapat kesalahan, klik Run. Kita bisa coba jalankan aplikasi buatan kita. Langkah selanjutnya adalah membuat Package. Untuk menjalankan aplikasi ini di handphone kita harus membuat file .jad , file inilah yang nantinya akan kita pindahkan ke handphone dan kita instal di handphone. Langkah-langkah pembuatan file .jad
- pilih Project
- pilih Package
- pilih Create Package
- Maka file .jad akan tercipta, dan file tersebut disimpan di dalam direk tori bin
