ClassDefNoFound on API 22 x_86 level API

Question

我在API level 22 (lollipop)手机中遇到了一个奇怪的问题。

手机使用这些API级别做工精细

• API 24
• API 23

但是，当我在API级别上运行我的应用程序22移动，它给了我下面的错误消息。

 Caused by: java.lang.ClassNotFoundException: Didn't find class "com.squareup.picasso.Picasso" 
    on path: DexPathList[[zip file 
    "/data/app/com.myapp.app-1/base.apk"],nativeLibraryDirectories=[/data/app/com.myapp.app-1/lib/x86, /vendor/lib, /system/lib]] 
    at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:56) 

然而，这并不是Picasso相关的问题，如果我删除Picasso library它开始让我对其他类的错误消息。

Process: com.myapp.app, PID: 16327 
    java.lang.NoClassDefFoundError: Failed resolution of: Lcom/myapp/app/VideosListActivity

您是否在更改后手动重新同步gradle？您是否还更改了build.gradle中的生成工具版本以匹配API 22？您显示的错误只有在gradle没有正确重建或重新生成时才会显示。我也尝试从命令行手动执行它...（在OS X中），./gradlew clean，./gradlew assemble
