Question

Error:warning: Ignoring InnerClasses attribute for an anonymous inner class
Error:(com.umeng.socialize.b.b) that doesn't come with an
Error:associated EnclosingMethod attribute. This class was probably produced by a
Error:compiler that did not target the modern .class file format. The recommended
Error:solution is to recompile the class from source, using an up-to-date compiler
Error:and without specifying any "-target" type options. The consequence of ignoring
Error:this warning is that reflective operations on this class will incorrectly
Error:indicate that it is not an inner class.

Answer 1

1、在proguard-rules.pro 里面加上-keepattributes EnclosingMethod
2、如果还是有问题在主项目build.gradle这里添加这句
defaultConfig {
multiDexEnabled true
}这是超过65536方法
3、还有你生成了你自己的签名文件
