Android使用Picasso Cache并获取NoClassDefFoundError错误(Android use Picasso Cache and get NoClassDefFoundError Error)
在我的应用程序中，我想使用下面的粘贴代码作为PicassoCache，但在使用后如：
PicassoCache.getPicassoInstance(context) .load(list.get(position).getStoreImage()) .placeholder(R.drawable.ic_messages) .into(holder.store_avatar);我得到这个错误：
Could not find class 'com.squareup.okhttp.CacheControl$Builder', referenced from method com.squareup.picasso.OkHttpDownloader.load 06-12 01:13:17.484 6246-6246/ir.pishguy.signalpresentationproject E/AndroidRuntime: FATAL EXCEPTION: main java.lang.NoClassDefFoundError: com.squareup.okhttp.OkHttpClientPicassoCache：

PicassoCache.getPicassoInstance(context) .load(list.get(position).getStoreImage()) .placeholder(R.drawable.ic_messages) .into(holder.store_avatar);i get this error:

对我来说组合
// Retrofit compile('com.squareup.retrofit2:retrofit:2.0.2') { exclude module: 'okhttp' } compile 'com.squareup.retrofit2:converter-gson:2.0.2' compile 'com.squareup.okhttp3:okhttp:3.2.0' // Picasso compile 'com.squareup.picasso:picasso:2.5.2'运作良好，但这里有一些答案说
compile 'com.squareup.okhttp:okhttp-urlconnection:x.x.x'可能有帮助。
For me combination
// Retrofit compile('com.squareup.retrofit2:retrofit:2.0.2') { exclude module: 'okhttp' } compile 'com.squareup.retrofit2:converter-gson:2.0.2' compile 'com.squareup.okhttp3:okhttp:3.2.0' // Picasso compile 'com.squareup.picasso:picasso:2.5.2'works well, but here some answers said that
compile 'com.squareup.okhttp:okhttp-urlconnection:x.x.x'may help.
