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'

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
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..
