【问题描述】:
我正在尝试开发一个应用程序,其中服务器必须每 5 秒向所有运行该应用程序的 android 设备发送通知。我决定使用(Google)Firebse Cloud Messaging 来发送通知,所以我首先尝试了指南的示例项目
https://firebase.google.com/docs/notifications/android/console-audience
但我无法让它工作。我遵循了所有的指示。我已经发布了我使用的代码。我还做了 file-->project structure-->notifications-->勾选了 Google Cloud Messaging。我在 android 5 设备上尝试了该应用程序。
当我打开 Firebase 控制台并发送通知时,我会在日志中看到刷新的令牌(来自 MyFirebaseInstanceIDService 类,方法 onTokenRefresh()),但是当我再次运行它并通过以下方式向单个设备发送通知时复制和粘贴令牌,没有任何反应。此外,当我从控制台向 用户细分 发送通知时,什么也没有发生。
我还尝试了来自同一网站的 Firebase 的相应 ios 示例项目,它在 iphone 上运行良好(所有通知都已发送)。我在这里遗漏了什么吗?
public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {
private static final String TAG = "MyFirebaseIIDService";
@Override
public void onTokenRefresh() {
// Get updated InstanceID token.
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
Log.d(TAG, "Refreshed token: " + refreshedToken);
sendRegistrationToServer(refreshedToken);
}
private void sendRegistrationToServer(String token) {
// TODO: Implement this method to send token to your app server.
}
}
MyFirebaseMessagingService :
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "MyFirebaseMsgService";
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.d(TAG, "From: " + remoteMessage.getFrom());
//Toast.makeText(getApplicationContext(),"FROM "+remoteMessage.getFrom(),Toast.LENGTH_LONG).show();
// Check if message contains a data payload.
if (remoteMessage.getData().size() > 0) {
Log.d(TAG, "Message data payload: " + remoteMessage.getData());
//Toast.makeText(getApplicationContext(),"MESSAGE: "+remoteMessage.getData(),Toast.LENGTH_LONG).show();
}
// Check if message contains a notification payload.
if (remoteMessage.getNotification() != null) {
//MainActivity.TestMethod();
Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
//Toast.makeText(getApplicationContext(),"MESSAGE: "+remoteMessage.getData(),Toast.LENGTH_LONG).show();
}
// Also if you intend on generating your own notifications as a result of a received FCM
// message, here is where that should be initiated. See sendNotification method below.
sendNotification(remoteMessage.getNotification().getBody());
}
private void sendNotification(String messageBody) {
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_stat_ic_notification)
.setContentTitle("FCM Message")
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
}
主要活动:
public class MainActivity extends AppCompatActivity {
private static final String TAG = "MainActivity";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (getIntent().getExtras() != null) {
for (String key : getIntent().getExtras().keySet()) {
String value = getIntent().getExtras().getString(key);
Log.d(TAG, "Key: " + key + " Value: " + value);
}
}
Button subscribeButton = (Button) findViewById(R.id.subscribeButton);
subscribeButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// [START subscribe_topics]
FirebaseMessaging.getInstance().subscribeToTopic("news");
// [END subscribe_topics]
// Log and toast
String msg = getString(R.string.msg_subscribed);
Log.d(TAG, msg);
Toast.makeText(MainActivity.this, msg, Toast.LENGTH_SHORT).show();
}
});
Button logTokenButton = (Button) findViewById(R.id.logTokenButton);
logTokenButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Get token
String token = FirebaseInstanceId.getInstance().getToken();
// Log and toast
String msg = getString(R.string.msg_token_fmt, token);
Log.d(TAG, msg);
Toast.makeText(MainActivity.this, msg, Toast.LENGTH_SHORT).show();
}
});
}
}
和 build.gradle(项目消息传递):
// Top-level build file where you can add configuration options commonto `all sub-projects/modules.`
buildscript {
repositories {
jcenter()
mavenLocal()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.1.3'
classpath 'com.google.gms:google-services:3.0.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
mavenLocal()
}
}
和 build.gradle(模块应用程序):
apply plugin: 'com.android.application'
android {
compileSdkVersion 24
buildToolsVersion "24.0.0"
defaultConfig {
applicationId "com.google.firebase.quickstart.fcm"
minSdkVersion 15
targetSdkVersion 24
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
packagingOptions {
exclude 'LICENSE.txt'
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
// Testing dependencies
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.1'
androidTestCompile 'com.android.support.test:runner:0.2'
androidTestCompile 'com.android.support:support-annotations:24.2.0'
compile 'com.android.support:appcompat-v7:24.2.0'
compile 'com.google.firebase:firebase-messaging:9.4.0'
compile 'com.google.firebase:firebase-core:9.4.0'
compile 'com.google.android.gms:play-services-gcm:9.4.0'
compile 'com.android.support:design:24.2.0'
}
apply plugin: 'com.google.gms.google-services'
...这是清单文件:

【问题讨论】:
-
您是否update the app manifest 获得了服务?
-
是的@qbix,我已经这样做了,但是还是不行……
-
查看您的
google-services.json文件以确认其中包含的值与您在 Firebase 控制台中的项目设置中的值匹配。特别是:项目 ID、包名称、应用 ID。 -
@qbix 我检查了所有这 3 个设置,它们对于项目和 json 都是相同的......
-
很难猜出可能是什么问题。你不需要
play-services-gcm:9.4.0,但这不应该破坏任何东西。 setup instructions 已完成。我在不同的项目中多次关注他们并取得了成功。
