First Add Dependency on Android Studio

/ * Pdf library dependency add on dependency build.gradle (Module:app) */

implementation 'com.github.barteksc:android-pdf-viewer:2.8.2'

That did not work for me. In order to get my Android project running again, I had to add jcenter() to the setting.gradle(Project Setting) file.

pluginManagement {

    repositories {

        gradlePluginPortal()

        google()

        mavenCentral()

        jcenter()

    }

}

or

or

pdfView.fromSource(DocumentSource)

or

pdfView.fromAsset(String)
