我正在尝试在我正在制作的Exchange Web Services Java API应用中使用Office365 Android,但不断收到此错误。

以下相关堆栈信息:

我的/ libs /文件夹中有httpclient 4.3.jar,这些是我的依赖项:

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.0.0'

// base OData library:
compile group: 'com.microsoft.services', name: 'odata-engine-core', version: '0.12.1'
compile group: 'com.microsoft.services', name: 'odata-engine-android-impl', version: '0.12.1', ext:'aar'

// choose the discovery and outlook services
compile group: 'com.microsoft.services', name: 'discovery-services', version: '0.12.1'
compile group: 'com.microsoft.services', name: 'outlook-services', version: '0.12.1'

// Azure Active Directory Library

}

是否有人能够发现问题或我如何解决问题? 感谢

答案 0 :(得分:6)

我尝试添加以下依赖项。现在它对我来说很好用

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.4.1</version>
</dependency>

有同样的问题。我通过升级org.apache.httpcomponents

下的所有pom.xml库来修复它

答案 2 :(得分:0)

我遇到了同样的问题,但修复了在pom中添加httpclient-osgi的问题

    <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpclient-osgi</artifactId>
        <version>4.5.1</version>
    </dependency>

工作正常..
