颤动火力基础消息崩溃目标 S（版本 31 及更高版本）要求FLAG_IMMUTABLE

Question

最近，我们将Android应用程序目标发布到31，该目标报告了Firebase消息传递（待定意外）中更多的崩溃（仅限Android OS 12用户）。当应用程序在通知接收其崩溃时处于暂停/后台状态。我已经尝试了可能的解决方案，但没有运气仍然崩溃。据我所知，我们必须在“待定意外启动”活动上添加PendingIntent.FLAG_IMMUTABLE，但不知道如何添加或修复此问题。

如果有人面临同样的问题并解决了。分享解决方案。

预先感谢...

E/AndroidRuntime( 7058): Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.

根据官方文档“如果你的应用针对Android 12，你必须指定你的应用创建的每个PendingIntent对象的可变性。这一额外要求提高了您的应用程序的安全性。”

Intent notificationIntent = new Intent(getApplicationContext(), MainActivity.class);

   
PendingIntent contentIntent = PendingIntent.getActivity(context,NOTIFICATION_REQUEST_CODE, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT | PendingIntent.FLAG_IMMUTABLE);

我们正在构建一个标准类型的Intent，它将打开我们的应用程序，然后在将其添加到我们的notification.In之前简单地将其包装在PendingIntent中，因为我们知道我们想要执行一个确切的操作，我们构建了一个PendingIntent，该PendingIntent不能被我们通过使用名为FLAG_IMMUTABLE的标志传递给它的应用程序修改。

我终于解决了这个问题。由于Firebase插件版本较低，它崩溃了，在升级了Android依赖项和Flutter插件后，它得到了解决。

第1步：在android/app/build.gradle

从

implementation 'com.google.firebase:firebase-messaging:20.1.5'

自

implementation platform('com.google.firebase:firebase-bom') // add this 
implementation 'com.google.firebase:firebase-messaging:23.0.0'
implementation 'com.google.firebase:firebase-iid:21.1.0' // add this

第二步：在Flutter pubspec.yaml中

从

firebase_core: ^0.5.0+1
firebase_messaging: ^7.0.3
firebase_remote_config: ^0.4.2
firebase_crashlytics: ^0.1.4+1
firebase_dynamic_links: ^0.6.3
firebase_auth: ^0.18.4+1

自

firebase_core: ^1.10.0
firebase_messaging: ^11.2.6
firebase_remote_config: ^2.0.0
firebase_crashlytics: ^2.5.0
firebase_dynamic_links: ^4.0.5
firebase_auth: ^3.3.6
