我HttpClient的4.3.jar我/库/文件夹，这些是我的依赖：

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

//compile 'org.apache.httpcomponents:httpcore:4.3.3' 
//compile 'commons-logging:commons-logging:1.2' 
//compile 'joda-time:joda-time:2.7' 
}

是否有人能够发现这个问题，或者我怎么可能修复它？谢谢

它再次。找到了解决方案？ – Tinashe

@Tinashe，不要放弃它！而是使用Office 365 sdk代替Android。 – mathletics

随着Office 365 SDK你有没有试过访问共享资源？像共享日历一样。 – Tinashe

我尝试通过添加以下依赖项。现在，它的工作对我罚款

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

太棒了！我没有使用android，但它为我解决了这个确切的错误！ – nterry

在哪个文件中，我把这个代码 –

@KrunalShah你应该把它放在你的maven项目的pom.xml中 – Rams

有同样的issue.I固定它通过升级所有org.apache.httpcomponents库pom.xml

下，我面临同样的问题，但固定加HttpClient的OSGi的在POM

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

它工作正常..
