如果使用Picasso同时也使用了okhttp库，那么项目运行的时候可能会报出一下异常：

Picasso detected an unsupported OkHttp on the classpath

针对该情况，网上说需要引入：compile 'com.squareup.okhttp:okhttp-urlconnection:2.2.0'

即同时引入一下三个包：

compile 'com.squareup.okhttp:okhttp:2.4.0'

compile 'com.squareup.okhttp:okhttp-urlconnection:2.2.0'
compile 'com.squareup.picasso:picasso:2.4.0'
