https://github.com/square/picasso/issues/541

若是使用Picasso同時也使用了okhttp庫，那麼項目運行的時候可能會報出一下異常：

Picasso detected an unsupported OkHttp on the classpath

針對該狀況，網上說須要引入：compile 'com.squareup.okhttp:okhttp-urlconnection:2.2.0'

即同時引入一下三個包：

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'
