I have the httpclient 4.3.jar in my /libs/ folder and these are my dependencies:
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 group: 'com.microsoft.aad', name: 'adal', version: '1.1.1' //compile 'org.apache.httpcomponents:httpclient:4.4' //compile 'org.apache.httpcomponents:httpcore:4.3.3' //compile 'commons-logging:commons-logging:1.2' //compile 'joda-time:joda-time:2.7' }
Is anyone able to spot the issue or how I could possibly fix it? Thanks
