解决warning: Ignoring InnerClasses attribute for an anonymous inner class

在proguard-rules.pro文件中添加

-keepattributes EnclosingMethod

然后在build.gradle编译配置中引用，例：

buildTypes {    debug {        debuggable true        jniDebuggable true        zipAlignEnabled true        minifyEnabled false        shrinkResources false        signingConfig signingConfigs.debug    }    release {        debuggable false        jniDebuggable false        zipAlignEnabled true        minifyEnabled true        shrinkResources true        signingConfig signingConfigs.release        proguardFiles getDefaultProguardFile('proguard-       android.txt'), 'proguard-rules.pro'    }}
