找不到java.lang.ClassNotFoundException: Didn't find class "cn.bingoogolapple.bgabanner.BGABanner" on path: DexPathList[[zip file "/data/app/com.ytlz.testbanner-2/base.apk"],nativeLibraryDirectories=[/data/app/com.ytlz.testbanner-2/lib/arm64, /system/lib64, /vendor/lib64]]

我使用as开发，新建一个moudle使用build方式引入BGABanner，然后把这个mudle打成arr包，在新的工程下引用这个arr包，一直提示找不到找不到java.lang.ClassNotFoundException: Didn't find class "cn.bingoogolapple.bgabanner.BGABanner" on path: DexPathList；请问博主这个怎么解决啊，我新建一个项目又测试了一遍还是不行，尝试build ，clean ，重启as，重新打包，项目也没有使用重复的应用，也没有使用分包模式，尝试降低版本到 2.2.1 还是报同样的错误
