Android系统从哪个版本开始,不记得了,不是4点几就是5.0,内部网络开始使用okhttp,而之前使用的是httpurlconnection和httpclient,所以以前的版本不能直接使用okhttp,要导入jar包

包冲突了,存在两个okhttp包,不知道应该调用哪一个包的方法就会出现这个问题

的确很奇怪,把那个jar包删了用  compile “com.squareup.okhttp3:okhttp:3.2.0″ 这样导看看?

java.lang.NoClassDefFoundError: okhttp3.OkHttpClient
项目中的这个2个moudle 用到了 Okhttp3
然后本人在 oss-android-sdk 依赖中加入了
compile “com.squareup.okhttp3:okhttp:3.2.0”
compile “com.squareup.okio:okio:1.6.0”
然后app中添加了
compile project(“:oss-android-sdk”)
但在5.X以下还是报错了

对啊,你下面的已经compile “com.squareup.okhttp3:okhttp:3.2.0″,然后上面的app又导入下面这个,然后又导入了okhttp3.2的jar包,不就冲突了吗?
