我们当前正在使用flutter开发一款可接收推送通知的应用。一切正常,直到我们进行了最后一次Flutter更新,现在我们仅在Android上的Firebase中获得了致命异常-FlutterFirebaseMessagingService。
我在Flutter git上找不到关于此的任何信息,所以这可能是一个Android问题。
当应用程序使用Firebase功能和Firebase Messaging获得新的通知时,就会发生这种情况。我们使用的示例数据:
{
notification: {
title: „hello",
body: „You got a new Message"
},
data: {
click_action: "FLUTTER_NOTIFICATION_CLICK",
additional: additional, // some integer values
message: messageText // Same as message body above
},
apns: {
payload: {
aps: {
badge: count,
},
},
},
token: deviceToken //this is a correct device id
}
admin.messaging().send(message)

是否有人已经对此错误有经验或有解决该错误的想法?
编辑:android / app / build.gradle:
def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
localPropertiesFile.withReader('UTF-8') { reader ->
localProperties.load(reader)
}
}
def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}
apply plugin: 'com.android.application'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
def keystorePropertiesFile = rootProject.file("key.properties")
def keystoreProperties = new Properties()
keystoreProperties.load(new FileInputStream(keystorePropertiesFile))

答案 0 :(得分:1)
错误消息提示iid
;实例ID服务。这可能由firebase-core
提供;同时它也可能是不兼容的版本,有时会导致方法和字段未知。
尝试更新:
classpath 'com.android.tools.build:gradle:3.0.1'
classpath 'com.google.gms:google-services:3.2.1'
到当前版本:
classpath 'com.android.tools.build:gradle:3.2.0'
classpath 'com.google.gms:google-services:4.1.0'
firebase-perf
插件必须位于顶部,而不是底部:
apply plugin: 'com.android.application'
apply plugin: 'com.google.firebase.firebase-perf'
该库也已过时(可能需要firebase-core
):
implementation 'com.google.firebase:firebase-core:16.0.4'
implementation 'com.google.firebase:firebase-perf:16.1.2'
我真的很奇怪,为什么FCM
没有依赖性(就像人们期望的那样):
implementation 'com.google.firebase:firebase-messaging:17.3.3'
一旦定位到API级别28,建议您设置一个通知渠道:
<meta-data
android:name="com.google.firebase.messaging.default_notification_channel_id"
android:value="@string/default_notification_channel_id" />
...当前支持库的版本为28.0.0
。
备注:无效的JSON语法可能(最有可能)来自错误地发布-否则其他平台也将无法运行;我刚刚添加了一个解释,它有什么问题,并删除了硬编码的值。堆栈跟踪讲述了一个完整的故事,没有暗示任何无效的语法。
