这是我的舱单:
<service android:name=".fcm.PshycoFirebaseMessagingServices">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
<service android:name=".fcm.PshycoFirebaseInstanceIDService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
</intent-filter>
</service>
当应用程序在后台和通知到达，然后默认通知来，不运行我的onmessagerreceived代码。
这是我的onMessageReceived代码。如果我的应用程序在前台运行，而不是在后台运行，就会调用这个函数。我怎么能运行这段代码时，应用程序是在后台太?
// [START receive_message]
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
// TODO(developer): 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. See sendNotification method below.
data = remoteMessage.getData();
String title = remoteMessage.getNotification().getTitle();
String message = remoteMessage.getNotification().getBody();
String imageUrl = (String) data.get("image");
String action = (String) data.get("action");
Log.i(TAG, "onMessageReceived: title : "+title);
Log.i(TAG, "onMessageReceived: message : "+message);
Log.i(TAG, "onMessageReceived: imageUrl : "+imageUrl);
Log.i(TAG, "onMessageReceived: action : "+action);
if (imageUrl == null) {
sendNotification(title,message,action);
} else {
new BigPictureNotification(this,title,message,imageUrl,action);
}
}
// [END receive_message]
为了能够从应用程序在后台发送的firebase通知中检索数据，您需要在通知数据集中添加click_action条目。
在firebase控制台设置额外的通知选项，如下所示:(你必须包括你想在应用程序中检索的任何额外数据):
并包括意图过滤器在你的manifest文件下的活动要启动
<activity
android:name=".MainActivity"
android:exported="true"
android:label="@string/app_name"
android:theme="@style/Theme.MyApp.SplashScreen">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<intent-filter>
<action android:name="FIREBASE_NOTIFICATION_CLICK" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
然后在你的onNewIntent活动中获取bundle数据:
@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
Bundle data = intent.getExtras();
if (data != null) {
for (String key : data.keySet()) {
Object value = data.get(key);
// do what you want with the data entries
Log.d(FIREBASE_TAG, "Key: " + key + " Value: " + value);
Toast.makeText(this, "Key: "+key+".... Value: "+value, Toast.LENGTH_LONG).show;
}
}
}
当你的应用程序在前台时，你可以像这样设置onmessagerecreceived:
@Override
public void onMessageReceived(@NonNull RemoteMessage message) {
Log.d(FIREBASE_TAG, "Message From: " + message.getFrom());
if (message.getNotification() != null) {
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
Map<String, String> data = message.getData();
if(data != null && !data.isEmpty()){
for(Map.Entry<String ,String > entry : data.entrySet()) {
intent.putExtra(entry.getKey(), entry.getValue());
}
}
//.......
// implement the rest of the code to show notification
//
}
}
像这样简单的总结
如果你的应用正在运行;
onMessageReceived ()
是触发器。
如果你的应用程序没有运行(通过滑动杀死);
onMessageReceived ()
不是直接触发和传递的。如果你有特殊的键值对。它们不工作，因为onmessagerecreceived()不工作。
我找到了这条路;
在你的启动器活动中，放入这样的逻辑，
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState, R.layout.activity_splash);
if (getIntent().getExtras() != null && getIntent().getExtras().containsKey("PACKAGE_NAME")) {
// do what you want
// and this for killing app if we dont want to start
android.os.Process.killProcess(android.os.Process.myPid());
} else {
//continue to app
}
}
在这个if块中，根据firebase UI搜索你的密钥。
在这个例子中，我的键和值就像上面那样;(对不起，语言=))
当我的代码工作时，我得到“com.rda.note”。
android.os.Process.killProcess(android.os.Process.myPid());
有了这行代码，我关闭了我的应用程序，打开谷歌播放市场
快乐编码=)
我在firebase-messaging-sw.js中添加了以下代码，
messaging.onBackgroundmessage((payload)=>{
console.log("background message detected!!");
console.log("message : ", payload);
})
这是触发每次消息接收在后台。但我无法在主线程中使用有效负载，因为SW不支持它。所以我做了很多研究，在一个Android论坛上找到了一个解决方案。
因此，解决方案是必须从请求有效负载中删除通知有效负载。
所以我把有效载荷从
{
"notification": {
"title": "Hey there",
"body": "Subscribe to AMAL MOHAN N youtube channel"
},
"to": "your-browser-token",
"data": {
"value1": "text",
"value2": "",
"value3": "sample3",
"value4": "sample4"
}
}
to
{
"to": "your-browser-token",
"data": {
"value1": "text",
"value2": "",
"value3": "sample3",
"value4": "sample4"
}
}
有效负载的变化会自动在前台消息和后台消息中触发receiveMessage()。
我在一个Android论坛上发现了这个，这对我来说很有用!如果这对你有用，请告诉我。
根据文件
Handle messages in a backgrounded app
When your app is in the background, Android directs notification
messages to the system tray. A user tap on the notification opens the
app launcher by default.
This includes messages that contain both notification and data
payload. In these cases, the notification is delivered to the device's
system tray, and the data payload is delivered in the extras of the
intent of your launcher Activity.
If you want to open your app and perform a specific action, set
click_action in the notification payload and map it to an intent
filter in the Activity you want to launch. For example, set
click_action to OPEN_ACTIVITY_1 to trigger an intent filter like the
following:
<intent-filter> <action android:name="OPEN_ACTIVITY_1" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
编辑:
基于这个线程:
不能使用Firebase Console设置click_action有效负载。您可以尝试使用curl命令或自定义http服务器进行测试
curl --header "Authorization: key=<YOUR_KEY_GOES_HERE>"
--header Content-Type:"application/json" https://fcm.googleapis.com/fcm/send
-d "{\"to\":\"/topics/news\",\"notification\":
{\"title\": \"Click Action Message\",\"text\": \"Sample message\",
\"click_action\":\"OPEN_ACTIVITY_1\"}}"
