成功地接收到了 Firebase推送通知
,无论应用程序是在被杀死、后台还是前台运行。
但是,如果应用程序被杀死,Infinix Note 5(Android One-Oreo)
和Oppo F9(Oreo)
将无法收到推送通知,它们仅在后台或前台运行时正常工作。
我阅读了很多文章,这篇和这篇提到中国手机存在此问题,并且有一些用户端的解决方法可以让这些通知在他们的手机上工作。
但我想知道是否有可能从开发方面让通知在每个Android设备上都工作。
我针对API 27进行目标设置,这是我的代码:
public class FirebaseMessagingService extends com.google.firebase.messaging.FirebaseMessagingService {
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
String from = remoteMessage.getFrom();
Map data = remoteMessage.getData();
JSONObject jsonObject = new JSONObject();
Set<String> keys = remoteMessage.getData().keySet();
for (String key : keys) {
try {
jsonObject.put(key, remoteMessage.getData().get(key));
} catch (JSONException e) {
e.printStackTrace();
}
}
message= jsonObject.getString("message");
sendNotification(message, urlToOpen);
private void sendNotification(final String msg, final String urlToOpen) {
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
PendingIntent.FLAG_ONE_SHOT);
String channelId = getString(R.string.notification_channel_general);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(this, channelId)
.setSmallIcon(R.drawable.notification_icon)
.setContentTitle("App Name")
.setContentText(msg)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setPriority(Notification.PRIORITY_MAX)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel(channelId,
"App Channel",
NotificationManager.IMPORTANCE_HIGH);
notificationManager.createNotificationChannel(channel);
}
notificationManager.notify(0, notificationBuilder.build());
Gradle
:Gradle 是一种现代化的构建工具,用于自动化构建、测试和发布软件。它支持多种编程语言,并使用 Groovy 或 Kotlin 作为其 DSL(领域特定语言)。compileSdkVersion 27
defaultConfig {
applicationId "com.myapp.app"
minSdkVersion 19
targetSdkVersion 27
versionCode 2
versionName "1"
multiDexEnabled true
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
vectorDrawables.useSupportLibrary = true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
debug {
// Disable fabric build ID generation for debug builds
ext.enableCrashlytics = false
}
}

Infinx 设备
,但是你是否已经在你的FirebaseMessagingService
中添加了android:stopWithTask="false"
,就像这个答案中所说的 https://dev59.com/71UK5IYBdhLWcg3w4jQv#51129304 - AskNilesh
