android - 在我的 Grocery 应用程序中遇到 firebase 推送通知

Question

我正在为我的 fyp 创建一个 android 应用程序，我已经完成了所有代码，但卡住了 firebase 推送通知。这个应用程序有两个不同的用户，一个是客户，另一个是店主。我试图在我的店主应用程序中实现推送通知。在店主应用程序中，当他接受客户订单时，我想在客户应用程序中发送通知，我尝试使用此代码但无法发送通知。我正在为此应用程序使用 firebase 实时数据库。

我已经尝试过去 3 天来解决这个问题，但无法解决这个问题。我也在 youtube 和 stackover flow 上搜索，但找不到任何令人满意的解决方案。

提到了我为实现 firebase 推送通知而编写的代码。

    }

    public void setMessage_id(long message_id) {
        this.message_id = message_id;

FCM结果

public class FCMResult {
    private String message_id;

    public FCMResult() {
    }

    public String getMessage_id() {
        return message_id;

FCMSendData

import java.util.Map;

public class FCMSendData {

    private Map<String,String> data;

    public FCMSendData(String to, Map<String, String> data) {
        this.to = to;

IFCM服务

import io.reactivex.Observable;

import retrofit2.http.Headers;
import retrofit2.http.POST;

public interface IFCMService {

    @Headers({
            "Content-Type:application/json",
            "Authorization:key=AAAAzkiH50E:APA91bETfnykxzAHx7Q4g5EFcPqZRHuyWi8S72OlnzFvxY4x_9o5MWl-BuxSB2ZUYt73Im1RJsOb55d7cTe3IPZR4fLIAaoJd_CaH1THCq3lxV4Rs6DfDdTtrC2HgIKNEgON2rD2ICGb"
    })
    @POST("fcm/send")
    Observable<FCMResponse> sendNotification(@Body FCMSendData body);

}

改造FCMClient

import retrofit2.Retrofit;
import retrofit2.adapter.rxjava2.RxJava2CallAdapterFactory;
import retrofit2.converter.gson.GsonConverterFactory;

public class RetrofitFCMClient {
    private static Retrofit instance;
    public static Retrofit getInstance(){

        if (instance == null)
            instance = new Retrofit.Builder()
                    .baseUrl("https://fcm.googleapis.com/")
                    .addConverterFactory(GsonConverterFactory.create())
                    .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                    .build();

            return instance;
    }
}

我的 FCM 服务

import com.google.firebase.messaging.FirebaseMessagingService;
import com.google.firebase.messaging.RemoteMessage;

public class MyFCMService extends FirebaseMessagingService {


    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {

        Map<String,String> dataRecv = remoteMessage.getData();

         if (dataRecv != null){
             common.showNotification(this,new Random().nextInt(),
                     dataRecv.get(common.NOTI_TITLE),
                     dataRecv.get(common.NOTI_CONTENT),
                     null);
         }

    }

    @Override
    public void onNewToken(String s) {
        super.onNewToken(s);
        common.updateToken(this,s);
    }
}

你应该在 serverAPP 中的 mainActivity 中更新令牌，就像客户端应用程序一样，在这样的两个应用程序中相同

     private void GotoHomeActivity(ServerUserModel serverUserModel) {
              FirebaseInstanceId.getInstance()
                        .getInstanceId()
                        .addOnFailureListener(new OnFailureListener() {
                            @Override
                            public void onFailure(@NonNull Exception e) {
                                Toast.makeText(MainActivity.this, ""+e.getMessage(), Toast.LENGTH_SHORT).show();
                                dialog.dismiss();
                                common.currentServerUser = serverUserModel;
                                startActivity(new Intent(MainActivity.this , HomeActivity.class));
                                finish();
                            }
                        }).addOnCompleteListener(new OnCompleteListener<InstanceIdResult>() {
                    @Override
                    public void onComplete(@NonNull Task<InstanceIdResult> task) {
                        dialog.dismiss();
                        common.currentServerUser = serverUserModel;
                        //this what i talk about (Update Token)
                        common.UpdateToken(MainActivity.this, task.getResult().getToken());
                        startActivity(new Intent(MainActivity.this , HomeActivity.class));
                        finish();
                    }
                });
}

通用类中的 UpdateToken

  public static void UpdateToken(Context context, String newToken) {

    FirebaseDatabase.getInstance()
            .getReference(common.TOKEN_REF)
            .child(common.currentServerUser.getUid())
            .setValue(new TokenModel(common.currentServerUser.getPhone() , newToken))
            .addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {

                    Toast.makeText(context, ""+e.getMessage(), Toast.LENGTH_SHORT).show();

                }
            });

}
