Android studio build failed upon adding pdfview library

I have a working android application to which I have added pdfView library. Upon adding the library adding additional functionality within the app and run on emulator, build failed with following trace: 

12:02:39 PM Executing tasks: [:app:clean, :app:generateDebugSources, :app:generateDebugAndroidTestSources, :app:mockableAndroidJar, :app:prepareDebugUnitTestDependencies, :app:assembleDebug]
12:03:58 PM Gradle build finished with 1440 error(s) in 1m 18s 260ms

Following are the changes I have done: 1. I have included pdflib library from File -> New -> Import module 2. Added line compile project(':pdfLib') to build.gradle file. 3. Added some trivial code around using the added lib.

Also received the following exception during runtime: 

Caused by: java.lang.UnsatisfiedLinkError: Couldn't load vudroid from loader dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/app.com.blynq.player-2.apk"],nativeLibraryDirectories=[/data/app-lib/app.com.blynq.player-2, /system/lib]]]: findLibrary returned null

  Please help me with this.

UPDATE:

build.gradle: 

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        applicationId "app.com.blynq.player"
        minSdkVersion 18
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

        android:layout_height="match_parent"
        android:id="@+id/imageView"

        android:layout_centerHorizontal="true"
        android:adjustViewBounds="true"
        android:src="@drawable/blynq_logo"
        />

    <VideoView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/videoView"
        android:layout_gravity="center"
        android:adjustViewBounds="true"
        android:visibility="invisible"
        />

    <com.joanzapata.pdfview.PDFView

        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:visibility="invisible"/>

</FrameLayout>

Code where I set pdf in pdfview: 

videoView.setVisibility(View.INVISIBLE);
imageView.setVisibility(View.INVISIBLE);
pdfView.setVisibility(View.VISIBLE);
pdfView.fromFile(new File(mediaPath)).defaultPage(1).enableSwipe(false).load();

If you look at the documentation to the library it says that it is based off of VuDroid, which is no longer maintained. The library itself is also no longer maintained; probably as a result of the VuDroid becoming deprecated. I would suggest that you try a library that is still being maintained such as:

Alternatively you could load your PDF in a WebView as described here.

just try this , this will solve your issue.

- Replace your compile project(':pdfLib') with
   **'com.joanzapata.pdfview:android-pdfview:1.0.4@aar'** or whatever library you want to add, because adding this type a library, it is
   download the library at run time and build the gradle
   properly,because adding library manually may occur some path issues
   etc.
