 Threfore, you should avoid to use that dependency for your release build.
 
 FYI, the following table describes the total number of method/field references in this library's release aar.
 This data is acquired by using [Dexcount Gradle Plugin](https://github.com/KeepSafe/dexcount-gradle-plugin).

 Due to the extensibility of this library, no-op version unfortunately has more than a few methods.
-If you want to eliminate such method count in your release build, consider having separate `Application` class only for your debug build which uses this library and just specify `debugCompile 'com.ms-square:debugoverlay:1.1.0'` in the dependencies section of build.gradle.
