Android push-уведомление Firebase иногда не отправляет уведомление

Question

Я создаю приложения для Android, которые имеют функцию уведомления о нажатиях. моя проблема; иногда мои приложения получали notif, но иногда нет. Я искал эту проблему в Google, и у меня нет такой же проблемы. Пожалуйста, мне нужна помощь. Ниже мой код.

это Gradle

apply plugin: 'com.android.application' 

android { 
    compileSdkVersion 25 
    buildToolsVersion "25.0.0" 
    defaultConfig { 
     applicationId "com.example.rusla.manual_notif" 
     minSdkVersion 16 
     targetSdkVersion 25 
     versionCode 1 
     versionName "1.0" 
     testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" 
    } 
    buildTypes { 
     release { 
      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 
} 

dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', { 
     exclude group: 'com.android.support', module: 'support-annotations' 
    }) 
    compile 'com.android.support:appcompat-v7:25.0.1' 
    compile 'com.google.firebase:firebase-messaging:10.0.0' 
    testCompile 'junit:junit:4.12' 
    compile 'com.mcxiaoke.volley:library:1.0.19' 
}

это мой Firebase класс обслуживания

package com.example.rusla.manual_notif; 

import android.util.Log;

public class FirebaseIDService extends FirebaseInstanceIdService { 
    private static final String TAG = "FirebaseIDService"; 

    @Override 
    public void onTokenRefresh() { 
     // Get updated InstanceID token. 
     String refreshedToken = FirebaseInstanceId.getInstance().getToken(); 
     Log.d(TAG, "Refreshed token: " + refreshedToken); 

     // TODO: Implement this method to send any registration to your app's servers. 
     sendRegistrationToServer(refreshedToken); 
    } 

    private void sendRegistrationToServer(String token) { 
     // Add custom implementation, as needed. 
    } 
} 

и это

package com.example.rusla.manual_notif; 

import android.util.Log; 

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

public class MyFirebaseMessagingService extends FirebaseMessagingService { 
    private static final String TAG = "FCM Service"; 
    @Override 
    public void onMessageReceived(RemoteMessage remoteMessage) { 
     // TODO: Handle FCM messages here. 
     // If the application is in the foreground handle both data and notification messages here. 
     // Also if you intend on generating your own notifications as a result of a received FCM 
     // message, here is where that should be initiated. 
     Log.d(TAG, "From: " + remoteMessage.getFrom()); 
     Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody()); 
    } 
} 

и ниже мой сервер коды на сторону PHP я использовать для отправки уведомления о

<!DOCTYPE html> 
<html> 
<head> 
    <title>Firebase Push Notification</title> 
</head> 
<style type="text/css"> 
    html, body { 
     height: 100%; 
    } 

    html { 
     display: table; 
     margin: auto; 
    } 

    body { 
     display: table-cell; 
     vertical-align: middle; 
    } 
    textarea { 
     width: 300px; 
     height: 150px; 
    } 
</style> 

<body> 
    <?php 
    require_once 'database.php'; 
    $sql = "SELECT * FROM users"; 
    $result = mysqli_query($conn,$sql); 

    ?> 
    <?php 
    //Displaying a success message when the notification is sent 
    if(isset($_REQUEST['success'])){ 
     ?> 
     <strong>Great!</strong> Your message has been sent successfully... 
     <?php 
    } 
    ?> 

    <form action='send.php' method='post'> 
     <select name='token'> 
      <?php 
      //Traversing trhough all values 
      while($row = mysqli_fetch_array($result)){ 
      //displaying the values in a dropdown list 
       ?> 
       <option value='<?php echo $row['token'];?>'><?php echo $row['email'];?></option> 

       <?php 
      } 
      ?> 
     </select><br /><br /> 
     <textarea name='message'></textarea><br /> 

     <button>Send Notification</button><br /> 
    </form> 

</body> 
</html> 

и Тхи is

<?php 

function send_notification ($tokens, $message) 
{ 
    $url = 'https://fcm.googleapis.com/fcm/send'; 

    $msg = array 
    (

    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_URL, $url);

    curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0); 
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields)); 
    $result = curl_exec($ch);   
    if ($result === FALSE) { 
     die('Curl failed: ' . curl_error($ch)); 
    } 
    curl_close($ch); 
    return $result; 
} 

//Checking post request 
if($_SERVER['REQUEST_METHOD']=='POST'){ 
    //Geting email and message from the request 
    $tokens[] = $_POST['token']; 
    $message = $_POST['message']; 
    $message_status = send_notification($tokens, $message); 
    $result = json_decode($message_status); 

    if($result->success){ 
     header('Location: sendNotification.php?success'); 
    }else{ 
     echo "<pre>";print_r($result);die; 
    } 
}else{ 
    header('Location: sendNotification.php'); 
} 


?> 

может быть любой человек может мой код повторной корректировки, так что я буду славить так много ..

Answer 1

Я рекомендую вам использовать data вместо notification. Сообщение данных всегда загружается наMessageReceived.

Прочитайте, как использовать данные, отредактируйте свой скрипт (php), чтобы использовать данные вместо уведомления.

Затем сделать свое собственное уведомление, как это:

@Override 
    public void onMessageReceived(RemoteMessage remoteMessage) { 

     // Use data! (: 
     if(remoteMessage.getData().size() > 0) { 

      if (remoteMessage.getData().get("message") != null) { 

       String title = (remoteMessage.getData().get("title") != null) ? remoteMessage.getData().get("title") : "Default Notification Title"; 
       showNotification(title, remoteMessage.getData().get("message")); 

      } 

     } 

     // When you send notification from the firebase console (avoid it for now. Is still very new) 
     if (remoteMessage.getNotification() != null) { 

      String title = (remoteMessage.getNotification().getTitle() != null) ? remoteMessage.getNotification().getTitle() : "Default Notification Title"; 

      showNotification(title, remoteMessage.getNotification().getBody()); 


     } 
    } 

private void showNotification(String title, String message){ 

Intent iNotifi; 
iNotifi = new Intent(this, MainActivity.class); 
      iNotifi.setAction(Intent.ACTION_MAIN); 
      iNotifi.addCategory(Intent.CATEGORY_LAUNCHER); 

PendingIntent pi = PendingIntent.getActivity(this, 0, iNotifi, 0); 

NotificationCompat.Builder builder = new NotificationCompat.Builder(this); 

     builder.setSmallIcon(R.drawable.yourNotificationIcon); 
     builder.setTicker(title); 
     builder.setContentTitle(title); 
     builder.setContentText(message); 
builder.setContentIntent(pi); 

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { 
      int color = ContextCompat.getColor(this, R.color.yourAccentColor); 
      builder.setColor(color); 
     } 

NotificationManager nm = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); 

     try { 
      nm.notify(0, builder.build()); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 

} 

Добавить это в манифесте:

<application...> 


<!-- Firebase notification icon --> 
     <meta-data android:name="com.google.firebase.messaging.default_notification_icon" 
      android:resource="@drawable/yourNotificationIcon" /> 
     <meta-data android:name="com.google.firebase.messaging.default_notification_color" 
      android:resource="@color/yourAccentColor" /> 

</application> 

Я надеюсь, что я помог (:
