【问题描述】：

我需要将sdk版本升级到31，因为我尝试使用react native vision camera package

建议升级到 sdk 版本 31

这里是链接https://mrousavy.com/react-native-vision-camera/docs/guides/troubleshooting/#android

这是我当前的 AndroidManifest.html。根据堆栈溢出帖子的其他帖子。我已经在主要活动中添加了“android:exported=true”。但是错误仍然在这里

当我尝试将android:exported=true 添加到接收器行receiver android:name="com.dieam.reactnativepushnotification.modules.RNPushNotificationBootEventReceiver 上面的inter-filter 时，应用程序已成功构建但总是退出对于firebase push notification 的inter-filter，文档推荐use android:export=false。当我使用 false 时，应用程序不会构建

我在更改 SDK 版本时开始收到此错误

buildscript {
    ext {
        ext {
        googlePlayServicesVersion = "+" // default: "+"
        firebaseMessagingVersion = "21.1.0" // default: "21.1.0"
       //working version without camera package
       // buildToolsVersion = "29.0.3"
       // minSdkVersion = 21
       // compileSdkVersion = 29
       // targetSdkVersion = 29
       // ndkVersion = "20.1.5948944"


         buildToolsVersion = "30.0.0"
         minSdkVersion = 26
         compileSdkVersion = 31
         targetSdkVersion = 31
         ndkVersion = "20.1.5948944"
    }
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath("com.android.tools.build:gradle:4.1.2")
        classpath('com.google.gms:google-services:4.3.1')
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

【问题讨论】：

我还没有尝试为申请添加android:exported 。但我确实尝试将android:exported 添加到包装intent-filter 的接收器中。该应用程序已构建，但它总是自行关闭
升级 android studio，更新 gradle 版本并为所有活动/服务/广播接收器设置exported= true/false。

【解决方案1】：

也许您使用的第三方库添加了一些缺少导出属性的新组件。当您打开带有清单的 xml 文件时，单击选项卡“Merged Manifest”：查看是否有组件，如果找到，只需使用 android:exported="false" 或 "true" 将其添加到清单中财产。所有组件如：activity、receivers、service 都必须包含 android:exported 字段。
