Awalnya, kami telah menggunakan GCM (Google Cloud Messaging) untuk mengirim pemberitahuan push ke perangkat Android, dan sekarang Google telah meluncurkan Firebase Cloud Messaging (FCM), versi GCM yang lebih baru dengan lebih banyak fitur Show
FCM adalah Layanan Perpesanan Cloud baru oleh Google di bawah merek Firebase, yang mewarisi infrastruktur inti GCM, ditambah SDK dan fitur baru untuk mempermudah pengembangan Perpesanan Cloud Tutorial ini berguna untuk para developer PHP yang ingin mengirimkan notifikasi FCM(Firebase Cloud Messaging) dengan menggunakan PHP Hei Technoz. semoga kamu baik-baik saja. Pada tutorial kali ini, kita akan melihat bagaimana cara mengirim push notification di android menggunakan php mysql. Kita semua tahu, notifikasi adalah hal yang ditampilkan di luar UI aplikasi kita. Kami menggunakan layanan Firebase Cloud Messaging (FCM) untuk mengirimkan notifikasi kepada pengguna. Jika Anda tidak tahu apa itu firebase, maka baca pengantar singkat di bawah ini. Jika tidak, Anda dapat melewati bagian itu Firebase Cloud Messaging (FCM)FCM adalah layanan yang dimiliki oleh Google. Memang sebelumnya bernama Google Cloud Messaging. Namun, Firebase adalah versi lanjutannya. Ini menyediakan banyak layanan seperti perpesanan cloud, basis data waktu nyata, Hosting, dll. Untuk tutorial ini, kami akan menggunakan perpesanan cloud untuk mengirim notifikasi ke perangkat android. Untuk mengetahui lebih lanjut, buka situs resmi Firebase Tutorial ini adalah kombinasi dari dua hal. Salah satunya adalah registrasi, login pengguna menggunakan REST api dan lainnya menampilkan notifikasi ke pengguna yang dituju. Jadi, Anda mungkin merasa tutorial ini agak panjang. Oleh karena itu, tutorial ini saya bagi menjadi dua modul, agar lebih mudah dipahami dan rapi 1. Modul AndroidPertama, Mari kita beralih ke modul aplikasi android untuk mengirim pemberitahuan push di android menggunakan PHP MySQL Notifikasi GedungUntuk membangun proyek untuk mengirim Pemberitahuan Push di Android menggunakan php mysql, Buka Android Studio dan mulai proyek baru atau gunakan proyek yang sudah ada, Anda ingin mengaktifkan pemberitahuan Firebase. Mulailah dengan aktivitas kosong baru. Pertama-tama kita harus membuat aplikasi dapat menampilkan notifikasi. Jadi, buat kelas baru <?xml version="1.0" encoding="utf-8"?>

</ScrollView>7 mengambil tiga argumen. Pertama adalah konteks, yang memberikan konteks aplikasi, kedua adalah judul notifikasi dan ketiga adalah isi notifikasi. Kami menggunakan ikon png untuk notifikasiMenambahkan Firebase ke ProyekKami sedang membangun sistem yang dapat mengirim notifikasi push di android ke perangkat yang dituju. Pertama, kita harus menambahkan Firebase di proyek kita. Ini jauh lebih sederhana. Buka menu proyek Alat->Firebase. Panel vertikal akan dibuka di sisi kanan yang memiliki banyak opsi yang tersedia untuk integrasi dalam proyek. Klik Cloud Messaging dan siapkan FCM. Klik tombol connect to Firebase. Ini akan meluncurkan browser di latar belakang di mana Anda harus mendaftar dengan akun Google Anda. Jadi, Anda akan masuk ke android studio Kedua, klik tombol 'Siapkan perpesanan cloud'. lalu klik 'Terima Perubahan' dan dependensi yang diperlukan akan ditambahkan ke proyek Anda. Tunggu hingga proyek berhasil dibangun dan Anda selesai. Firebase ditambahkan dalam proyek Anda. Anda akan melihat centang hijau di panel kanan seperti yang ditunjukkan pada gambar di bawah  Menghasilkan tokenDengan demikian, setiap perangkat didaftarkan ke Firebase dengan token pendaftaran yang unik. Segera setelah kami akan menginisialisasi aplikasi, itu menghasilkan token. kita dapat menggunakannya untuk mengirim notifikasi ke perangkat itu saja. pertama-tama kami akan membuat token dan menampilkannya untuk memastikan bahwa kami telah berhasil menyiapkan firebase dan kami mendapatkan token.

}6 seperti yang ditunjukkan pada gambar di bawahLayar di atas menampilkan token yang dihasilkan. namun, saya tidak dapat menunjukkan token lengkap karena alasan keamanan 🙂 Tetapi Anda akan mendapatkan gambaran bagaimana itu akan ditampilkan. Saat string dihasilkan, kami mendapat konfirmasi bahwa firebase sudah diatur dengan benar. Token memainkan peran penting dalam mengirimkan pemberitahuan push di android menggunakan php mysql Membangun Mekanisme Login/PendaftaranMenambahkan kode yang diperlukanSekarang, apa yang akan kita buat mekanisme login dan pendaftaran pengguna yang sederhana. Dengan demikian kami akan memilih salah satu dari pengguna terdaftar dan mengirimkan pemberitahuan dari halaman web. Untuk itu, kita harus membuat aktivitas login, Jadi, mari perbarui kode di tata letak <?xml version="1.0" encoding="utf-8"?>

</ScrollView>_1Itu saja untuk aplikasi android. Sekarang, kita akan bergerak menuju modul sisi server. Ini sederhana, dan cepat. Pastikan Anda memiliki setidaknya pengetahuan dasar tentang PHP dan MySQL sebelum melangkah lebih jauh. Jika Anda merasa perlu mempelajari PHP, maka Anda dapat mengunjungi kategori tutorial PHP 2. Modul Server (PHP MySQL).Kedua, Menyiapkan hal-hal sisi server agar aplikasi kami bekerja dengan cepat dan mengirim pemberitahuan push di android menggunakan php mysql Menyiapkan basis dataDi sini, kita harus menunjukkan notifikasi kepada pengguna yang dituju. Jadi, untuk mengidentifikasi pengguna unik, kami akan membuat akun pengguna untuk mengimplementasikan pengiriman notifikasi ke pengguna unik. Jadi, buat database dengan nama apa pun pilihan Anda. Selanjutnya, mari buat tabel baru di dalamnya yang memiliki bidang seperti id, email, kata sandi, token. Anda dapat menggunakan kueri berikut untuk membuat tabel <?xml version="1.0" encoding="utf-8"?>

Untuk itu, kita harus membuat file PHP yang akan login atau mendaftar pengguna dan menyimpan detailnya bersama dengan token yang dihasilkan. Selanjutnya, Kami akan menggunakan token tersebut untuk mengidentifikasi perangkat secara unik dan mengirimkan pemberitahuan ke perangkat tersebut Membuat API PHPUntuk mengirim notifikasi push di android menggunakan php mysql, kita harus membuat api PHP.

}6. Terakhir, Kami menampilkan pesan sukses atau gagal yang relevan kepada penggunaMengirim push notification di android menggunakan php mysqlItu dia. Akhirnya, Kami telah selesai dengan proyek kami. Sekarang mari kita coba jalankan aplikasinya. Lihat layar di bawah ini untuk pengiriman notifikasi yang berhasil Demikian Lihat push notification di android menggunakan php mysql sebagai berikut Selamat. Anda telah membuatnya menjadi mungkin. Mari bertepuk tangan untuk dirimu sendiri. 🙂 Catatan. Jika Anda menjalankan aplikasi di emulator android dan tidak mendapatkan notifikasi, coba jalankan di perangkat nyata. Ini mungkin terjadi karena versi Layanan Google Play yang sudah usang diinstal pada emulator. Umumnya, kami tidak memperbarui layanan play pada emulator dan kami menggunakan versi yang lebih baru dalam pengembangan proyek. Jadi, ini mungkin menyebabkan masalah Jika Anda memiliki pertanyaan tentang tutorial, tanyakan di bagian komentar di bawah.
