Push Notification with Parse.com [Android Studio]

Beberapa hari ini saya berfikir bagaimana cara membuat sebuaah aplikasi yang memiliki notifikasi. Mulai dari situ saya mencari-cari beberapa situs yang menyediakan notifikasi. mulai dari pubnub.com, firebase.com, parse.com, dan google cloud message (gcm). Tepatnya mulai dari 2 hari kemarin (selasa, 15-Des-2015) satu persatu situs tersebut mulai saya jajal, alhasil malam ini saya baru berhasil mengimplementasikan push notifikasi dari situs parse.com, walaupun belum maksimal hasilnya, tetapi bisa memuaskan keingintahuan saya untuk membuat notifikasi di android ini. Hasil dari "tahap pencarian" saya, saya coba jabarkan di artikel ini.

referensi: http://www.androidhive.info/2015/06/android-push-notifications-using-parse-com/

Langkah-Langkah:

1. Lakukan Sign up pada parse.com

2. Membuat projek baru

beri nama. misal <parse>

3. Akses Application ID dan Client Key projek yang sudah di buat

4. Membuat project baru di android Studio. source code bisa di ambil disini -> https://github.com/ardhimaarik/parse

 File - > New -> New Project...

atau 

Start a new Android Studio Project

5. Download Parse-1.9.1.jar

6. Set depedency di build.gradle(Module:app)

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.parse.bolts:bolts-android:1.+'
    compile fileTree(dir: 'libs', include: 'Parse-*.jar')
}

Klik 

6. Buatlah struktur folder seperti gambar dibawah ini
