Java 无法连接到天气API,java,android,android-studio,weather-api,Java,Android,Android Studio,Weather Api,我需要一些帮助。这是我的代码和错误。我是一个初学者，正在使用weather.org作为API。我在网上搜索过，但都有相同的答案。这是最重要的 android:UseClearTextTraffic=“true” 和 android:networkSecurityConfig=“@xml/network\u security\u config” 我的XML应用程序标记具有： <uses-permission android:name="android.permission.INTERNET

我需要一些帮助。这是我的代码和错误。我是一个初学者，正在使用weather.org作为API。我在网上搜索过，但都有相同的答案。这是最重要的

android:UseClearTextTraffic=“true” 和 android:networkSecurityConfig=“@xml/network\u security\u config”

我的XML应用程序标记具有：

<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"/>

<application
    ...
    android:usesCleartextTraffic="true"
    android:networkSecurityConfig="@xml/network_security_config"
    ...>

    <uses-library android:name="org.apache.http.legacy"
        android:required="false"/>

</application>

我的netword\u security\u config.xml是：

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">http://api.openweathermap.org</domain>
    </domain-config>
</network-security-config>

当我在MainActivity.java和network_security_config.xml中编辑http到https时，我得到了以下错误：
