java - NullPointerException Inet6AddressImpl

Question

我有一个具有用于toreact native的 SDK 的应用程序。我使用这个第三方包，这让我例外。custom bridgesnative code

我的应用程序可以在真实设备和模拟器中运行，Android 9+并且日志中没有异常或其他内容。但是当我在8.08.1 中运行应用程序时，我的应用程序会引发异常。

我的应用程序有 androidX 依赖项，而第三个包没有，所以我不知道这是否是个问题。

也可以与cleartexttraffic？或在版本之间更改的某些权限。

反应原生 android 清单

        <service android:name="org.eclipse.paho.android.service.MqttService"></service>

    </application>

</manifest>

我用于桥梁的自定义 sdk

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.sweeprapitest">
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.CHANGE_WIFI_MULTICAST_STATE"/>
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <application
        android:usesCleartextTraffic="true">
        <service android:name="org.eclipse.paho.android.service.MqttService"></service>
    </application>

</manifest>

我希望我的应用程序适用于 android 8，这是例外
