我正在从谷歌firebase发送推送通知,我的Android应用程序的目标是Android 5.0:
我的推送通知代码是:
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
String badge = "0";
Uri uri = Uri.parse(
getString(R.string.app_host_name)
);
Map<String, String> data = remoteMessage.getData();
if (data.size() > 0) {
try {
uri = Uri.parse(
data.get("link")
);
badge = data.get("badge");
} catch (NullPointerException e) {
//
}
}
if (remoteMessage.getNotification() != null) {
RemoteMessage.Notification notification = remoteMessage.getNotification();
sendNotification(notification.getTitle(), notification.getBody(), uri.toString(), badge);
}
}
private void sendNotification(String title, String body, String url, String badge) {
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
if (Patterns.WEB_URL.matcher(url).matches()) {
intent.putExtra("link", url);
}
PendingIntent pendingIntent = PendingIntent.getActivity(
this,
0,
intent,
PendingIntent.FLAG_UPDATE_CURRENT
);
Resources resources = getApplicationContext().getResources();
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(this, "default")
.setColor(
resources.getColor(R.color.colorPrimaryDark)
)
.setSmallIcon(
R.drawable.ic_stat_icon
)
.setContentTitle(title)
.setContentText(body)
.setAutoCancel(true)
.setNumber(Integer.parseInt(badge))
.setLargeIcon(
BitmapFactory.decodeResource(
resources,
R.mipmap.ic_launcher
)
)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= 26) {
NotificationChannel notificationChannel = new NotificationChannel(
"default",
"Main notification channel",
NotificationManager.IMPORTANCE_HIGH
);
notificationManager.createNotificationChannel(
notificationChannel
);
}
notificationManager.notify(
1,
notificationBuilder.build()
);
}
当应用程序处于活动/打开/不在后台时,一切都非常完美,但是当它不是时,通知不会被分组,没有显示数字,并且对所有这些设置都没有反应,我是什么能够通过清单设置只改变小图标和圆形颜色
<meta-data
android:name="com.google.firebase.messaging.default_notification_icon"
android:resource="@drawable/ic_stat_icon" />
<meta-data
android:name="com.google.firebase.messaging.default_notification_color"
android:resource="@color/colorPrimaryDark" />
但为什么呢?这就像应用程序处于后台通知时不使用活动代码中的设置,而是仅使用AndroidManifest中的某种“默认”设置。
答案 0 :(得分:2)
正如你在评论中所说:
当app在后台时,app不会使用setNumber,setAutoCancel,setSmallIcon,setLargeIcon选项
这是因为您正在使用通知有效负载发送仅在前台触发的通知。
因此,当您的应用在后台时,它不会输入此方法。
要解决此问题,您可以单独使用data
有效负载:
"data": {
"titles": "New Title",
"bodys": "body here"
}
因为当您的应用处于前台/后台时,数据有效负载将进入onMessageReceived()
。
然后在fcm中你可以这样做:
if (remoteMessage.getData().size() > 0) {
title = remoteMessage.getData().get("titles");
body = remoteMessage.getData().get("bodys");
}
