我一直在谷歌搜索很多时间,但我找不到任何问题的解决方案:我想在Android中使用FireBased消息,以便向所有下载我的应用程序的用户发送通知。
我试图找到很好的教程,但我发现只有一些显示了一次为一个人发送的ro,而不是所有用户都是通用的东西,而且我也找不到一个很好的教程来解释如何安装FCM,实际上有效......
是否有人可以指导我或引导我使用我可以使用的东西?
有关如何使用FCM的任何帮助或指示,还是有其他更好,更简单的解决方案?
谢谢
编辑:
我一直在尝试安装firebase消息,因此我编辑了我的清单并添加了这些服务:
<service android:name=".MyFirebaseMessagingService">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT"/>
</intent-filter>
</service>
<service android:name=".MyFirebaseInstanceIDService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
</intent-filter>
</service>
还更新了我的gradle文件并添加了我需要的内容。
但是在尝试运行应用程序时,我不断收到此错误日志消息:
FirebaseInstanceId: background sync failed: MISSING_INSTANCEID_SERVICE
有什么帮助吗?
我的清单文件的一部分:
<uses-permission android:name="android.permission.INTERNET" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/MyMaterialTheme">
<meta-data
android:name="com.facebook.sdk.ApplicationId"
android:value="@string/facebook_app_id" />
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />

<service

<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>

我的基于火的文件:
import android.util.Log;
import com.google.firebase.iid.FirebaseInstanceId;
import com.google.firebase.iid.FirebaseInstanceIdService;
//Class extending FirebaseInstanceIdService
public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {
private static final String TAG = "MyFirebaseIIDService";
@Override
public void onTokenRefresh() {
//Getting registration token
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
//Displaying token on logcat
Log.d(TAG, "Refreshed token: " + refreshedToken);
}
private void sendRegistrationToServer(String token) {
//You can implement this method to store the token on your server
//Not required for current project
}
}
