Firebase 消息错误(仅限安卓) - 新推送通知出现致命异常



我们目前正在使用 flutter 开发一个接收推送通知的应用程序。一切正常,直到我们进行了最后一次 Flutter 更新,现在我们在 Firebase 中得到了一个致命异常 - FlutterFirebaseMessagingService 仅在 Android 上。

我在颤振 git 上找不到任何关于这个的东西,所以这可能是一个安卓问题。

当应用使用 Firebase 函数和 Firebase 消息功能收到新通知时,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)

有没有人已经遇到过此错误或知道如何解决它?

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))

错误消息提示iid; 实例 ID 服务。 这可能由firebase-core提供; 虽然它也可能是不兼容的版本,有时会导致未知的方法和字段。

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'

此外,库已过时(可能需要firebase-core(:

implementation 'com.google.firebase:firebase-core:16.0.4'
implementation 'com.google.firebase:firebase-perf:16.1.2'

虽然我真的想知道,为什么FCM没有依赖关系(正如人们所期望的那样(:

implementation 'com.google.firebase:firebase-messaging:17.3.3'

一旦以 API 级别 28 为目标,还建议设置一个通知通道:

<meta-data
android:name="com.google.firebase.messaging.default_notification_channel_id"
android:value="@string/default_notification_channel_id" />

。支持库目前的版本为28.0.0

备注:无效的JSON语法可能(很可能(来自错误发布 - 否则其他平台也无法运行;我刚刚添加了它有什么问题的解释,并删除了硬编码值。堆栈跟踪讲述了一个完全不同的故事,没有暗示任何无效的语法。
