Hi HttpClient is not supported any more in sdk 23. In-order to use Http Connection you need to do the following steps Add this to your gradle: android { useLibrary 'org.apache.http.legacy' compileSdkVersion 23 buildToolsVersion "23.0.2" } dependencies { compile fileTree( dir : 'libs' , include : [ '*.jar' ]) testCompile 'junit:junit:4.12' compile 'com.android.support:appcompat-v7:23.1.1' compile 'com.android.support:design:23.1.1' compile 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2' } OR You also may try to download and include HttpClient jar directly into your project
