Steps to reproduce / Describe in detail - Just keep ypur minsdkversion 19 and compile and run the project

[hrishikesh-kadam]

@anuragvarshney You will have to add Multidex support in your app module like the way we have added in our sample app module. See last 2 lines of the log you submitted, it says -

The number of method references in a .dex file cannot exceed 64K. Learn how to resolve this issue at https://developer.android.com/tools/building/multidex.html

So, this isn't a FolioReader bug. Once it gets resolved, please do close the issue.

@hrishikesh-kadam after enabling multidex some of the dependencies in folioreader were clashing with my project I was getting this error

so I excluded some dependencies from folio reader and included folioreader in this way implementation ('com.folioreader:folioreader:0.5.1'){ exclude group: "org.slf4j" exclude group: "joda-time" } will it effect the functionality of folioreader in any way ?

[hrishikesh-kadam]

Not sure, we never got exceptions like these. Even we have used multidex in the sample app module.

[anuragvarshney]

so this is not the problem of multidex some of the dependencies were clashing in my project and the library so I wanted to ask that excluding those would make any difference or not?

[hrishikesh-kadam]

@anuragvarshney I did reply saying "Not sure". Because we never had any issue like that, can't comment on it.

[anuragvarshney]

@hrishikesh-kadam thanks for your help and prompt response, closing this issue
