<WebView
    android:id="@+id/web_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

mainActivity.java:

public class MainActivity extends AppCompatActivity {

@SuppressLint("SetJavaScriptEnabled")
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    final WebView webView;

    webView = (WebView)findViewById(R.id.web_view);

    webView.getSettings().setJavaScriptEnabled(true);
    webView.loadUrl("https://docs.google.com/viewer?url=https://www.w3.org/WAI/ER/tests/xhtml/testfiles/resources/pdf/dummy.pdfhttps://www.w3.org/WAI/ER/tests/xhtml/testfiles/resources/pdf/dummy.pdf");
}

}

Solution

As the user @CommonsWare say, you can't open a PDF in the webview. The best solution would be download it and send it across an intent to a PDF dedicated reader app the user should have, or implement a special class to open it inside your own app.
