python을 이용해서 Firebase Cloud Messaging을 통해서 안드로이드 폰에 알람을 띄우는 것을 구현해봤다.
android에 firebase를 연결하는 거나 python의 모듈을 다운 받는 것은 생략한다.

package com.example.smarttrashcanapplication;

public class FirebaseInstanceIDService extends FirebaseMessagingService {
private static final String TAG = "FirebaseMsgService";
private String msg, title;
@Override

super.onNewToken(s);
Log.d("NEW_TOKEN", s);

intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
final String CHANNEL_ID = "채널 아이디";
NotificationManager mManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
final String CHANNEL_NAME = "채널 이름";
final String CHANNEL_DESCRIPTION = "채널 ";
final int importance = NotificationManager.IMPORTANCE_HIGH;
NotificationChannel mChannel = new NotificationChannel(CHANNEL_ID, CHANNEL_NAME, importance);
mChannel.setDescription(CHANNEL_DESCRIPTION);
mChannel.enableLights(true);
mChannel.enableVibration(true);
mChannel.setVibrationPattern(new long[]{100, 200, 100, 200});
mChannel.setSound(defaultSoundUri, null);
mChannel.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);
mManager.createNotificationChannel(mChannel);
}
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, CHANNEL_ID);
builder.setAutoCancel(true);
builder.setDefaults(Notification.DEFAULT_ALL);
builder.setWhen(System.currentTimeMillis());
builder.setSmallIcon(R.mipmap.ic_launcher);
builder.setContentText(content);
builder.setContentText(title);
builder.setSound(defaultSoundUri);
builder.setVibrate(new long[]{500, 500});
mManager.notify(0, builder.build());
}

위와 같이 FCM을 받고 그것을 바로 Notification을 띄워주는 것을 구현한다.

FirebaseMessaging.getInstance().getToken()
.addOnCompleteListener(new OnCompleteListener<String>() {
@Override
public void onComplete(@NonNull Task<String> task) {
if (!task.isSuccessful()) {
Log.w(TAG, "Fetching FCM registration token failed", task.getException());
return;
}
String token = task.getResult();
Log.d(TAG, "token : "+token);
}
});

위와 같은 코드를 통해서 token을 받아와야한다.

from pyfcm import FCMNotification
APIKEY = "APIKEY"
TOKEN = "TOKEN"
push_service = FCMNotification(APIKEY)
def sendMessage(body, title):
data_message = {
"body":body,
"title":title
}
result = push_service.single_device_data_message(registration_id=TOKEN, data_message=data_message)
print(result)
#Execution area
sendMessage("알람 제목", "알람 내용")

위와 같은 코드를 통해서 TOKEN가 가리키는 기기에 알람을 보낸다.
