android - API 22 x_86级API上的ClassDefNoFound

Question

我在API level 22 (lollipop)手机中遇到一个奇怪的问题。

使用这些API级别的手机运行正常

API 24

API 23

但是，当我在API级别22移动版上运行我的应用程序时，它会显示以下错误消息。

     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)

但是，这不是与Picasso相关的问题，如果我删除Picasso library，它会在其他类上给我错误消息。

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

更改后，您是否手动重新同步了gradle？您还更改了build.gradle中的构建工具版本以匹配API 22吗？您显示的错误只有在gradle尚未正确重建或重新同步时才出现。我还将尝试从命令行手动执行此操作(在OS X中)，./gradlew clean，./gradlew assemble
