篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了在我的Grocery应用程序中被firebase推送通知卡住了。相关的知识,希望对你有一定的参考价值。

我正在为我的FPP创建一个安卓应用程序,我已经完成了所有的代码,但被firebase推送通知卡住了,这个应用程序有两个不同的用户,一个是客户,另一个是店员。我试图在我的店长应用中实现推送通知。在店长应用中,当他接受客户的订单时,我想在客户应用中发送通知,我尝试用这个代码,但无法发送通知。我正在使用firebase实时数据库的这个应用程序。

我已经尝试了过去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,但无法得到任何满意的解决方案。

下面是我写的实现firebase推送通知的代码。

fragmentOrder

public class fragmentOrders extends Fragment {

    private View orderView;
    private CompositeDisposable compositeDisposable = new CompositeDisposable();
    private IFCMService ifcmService;
    private DatabaseReference tokenRef;
    public fragmentOrders() {
        // Required empty public constructor
    }


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
         orderView = inflater.inflate(R.layout.fragment_orders, container, false);

        ifcmService = RetrofitFCMClient.getInstance().create(IFCMService.class);

        tokenRef = FirebaseDatabase.getInstance().getReference(common.TOKEN_REF);


        return orderView;
    }


    @Override
    public void onStop() {
        super.onStop();
        compositeDisposable.clear();
    }

    private void showOrders() {

        FirebaseRecyclerOptions<OrderModel> options = new FirebaseRecyclerOptions.Builder<OrderModel>()

改装FCMC客户端

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;
    }
}

MyFCMService

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);
    }
}

答案

你应该在serverAPP的mainActivity中更新Tokens,就像客户端应用一样,在两个应用中也一样,就像这样

     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();
                    }
                });
}

普通类中的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();

                }
            });

}
