Thanks for contacting us.
The hintTextColor is part of the android material design package and this issue can be in result of different package versions. PDFTron SDK is using the version below:

Hi Saeed Bazzaz,

Thanks for reply.

I tried with new separate project in which we have dependencies of version ‘1.1.0’

implementation ‘androidx.appcompat:appcompat:1.1.0’
implementation ‘’

its working fine in new project but getting issue in existing project in which we want integrate.


Hi Pawan,

This is a very typical issue with Android dependency mismatch.

In this case, 1.4.0 is needed, so you need the following in your Gradle:

configurations.all {
        resolutionStrategy.force ""

What this does is it will make all library using this specific version so you don’t end up with strange errors.

Could you please look into updating your Gradle and try again? Thanks.
