java - 在 java android studio 中实现 twilio 可编程语音调用时遇到一些错误

Question

我在 java android studio 中实现了 Twilio 可编程语音调用，正如他们在文档中给出的描述，但在运行时遇到了一些错误

以下是我面临的错误:

 Exception in thread "main" java.lang.NoSuchFieldError: INSTANCE
        at org.apache.http.conn.ssl.SSLConnectionSocketFactory.<clinit>(SSLConnectionSocketFactory.java:144)
        at org.apache.http.impl.conn.PoolingHttpClientConnectionManager.getDefaultRegistry(PoolingHttpClientConnectionManager.java:109)

        at com.intellij.rt.execution.application.AppMainV2.main(AppMainV2.java:131)

我试图排除像这样的 http 库

implementation (group: "com.twilio.sdk", name: "twilio", version: "7.34.1")
{

 exclude group: 'org.apache.httpcomponents' ,module:'httpclient'

exclude group: 'org.apache.httpcomponents' ,module:'httpcore'
    }

implementation (group: "com.sparkjava", name: "spark-core", version: "2.7.1")
{

 exclude group: 'org.apache.httpcomponents' ,module:'httpclient'

 exclude group: 'org.apache.httpcomponents' ,module:'httpcore'
    }

implementation (group: "org.slf4j", name: "slf4j-simple", version: "1.7.21")
{

 exclude group: 'org.apache.httpcomponents' ,module:'httpclient'

 exclude group: 'org.apache.httpcomponents' ,module:'httpcore'
    }

当我尝试上述解决方案时，错误发生了变化:

>Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/http/ProtocolVersion
    at com.twilio.http.TwilioRestClient$Builder.build(TwilioRestClient.java:102)

    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
    ... 9 more

这是我的java代码:

public static void main(String[] args) throws URISyntaxException {

    Twilio.init(ACCOUNT_SID, AUTH_TOKEN);

    String from = "+18572632XXX";
    String to = "+92**********";

    Call call = Call.creator(new PhoneNumber(to), new PhoneNumber(from),
            new URI("http://demo.twilio.com/docs/voice.xml")).create();


    System.out.println(call.getSid());
}

我已经包含了所有必要的库:

>implementation group: "com.twilio.sdk", name: "twilio", version: "7.34.1"</br>

>implementation group: "com.sparkjava", name: "spark-core", version: "2.7.1"</br>

>implementation group: "org.slf4j", name: "slf4j-simple", version: "1.7.21"</br>

我没有这方面的经验，请帮忙

这里是 Twilio 开发人员布道者。正如您所注意到的，Android 在使用我们的 Java SDK 时会遇到麻烦，因为它的依赖项之一是用于 HTTP 的 Apache 库。你想做的是使用我们的 Android SDK用于调用电话。

您可以查看如何使用它的示例 here ，以及通过 quickstart这将带您完成整个过程。

在您的示例中，您使用的 Java SDK 在您的应用程序中存在安全问题，因为它现在将您的帐户凭据硬编码到您的最终 APK 中。我在 blog post 中解释了为什么这不是一个好主意.

希望对你有帮助。
