Usage

Just clone the project and trance the source code, It's realy easy and clear. Here an example how to use this lib.

Step 1. Add the JitPack repository to your build file, Add it in your root build.gradle at the end of repositories:

allprojects {
        repositories {
            maven { url 'https://jitpack.io' }
        }
    }

Step 2. Add the dependency

}

Step 3. Add PDFViewer into your xml

            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="#009688" />
