Manifest merger failed : uses-sdk:minSdkVersion 16 cannot be smaller than version 19 declared in library [com.github.mhiew:android-pdf-viewer:3.2.0-beta.3] transformed/jetified-android-pdf-viewer-3.2.0-beta.3/AndroidManifest.xml as the library might be using APIs not available in 16
Suggestion: use a compatible library with a minSdk of at most 16,
or increase this project's minSdk version to at least 19,
or use tools:overrideLibrary="com.github.barteksc.pdfviewer" to force usage (may lead to runtime failures)

Open your android project, then go to the gradle file of this plugin. there you can change the minimum SDK version to 16 for your project only. No need for change at repository level.

However, be careful choosing the minimum support SDK version since this library is using native pdf library. changing supporting SDK range may lead to unexpected behaviour due to deprecated functionality
