To open pdf in Webview , it better to show pdf via google doc service,

WebView webView = (WebView) context.findViewById(R.id.webView1);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setLoadWithOverviewMode(true);
webView.getSettings().setUseWideViewPort(true);
webView.loadUrl("http://drive.google.com/viewerng/viewer?embedded=true&url=" + pdf");

this may help you

I'm not a huge fan of this solution because it opens the browser app which isn't really what I want to do if I'm embedding a webview within the app. – CodyEngel May 14 '15 at 20:32
You may need to override the WebViewClient for the WebView in order to make it not open the browser (redirects might be the cause). See this: http://stackoverflow.com/a/18921867/2353588 – wblaschko Nov 15 '16 at 21:34

No, you can`t use WebView to show a PDF file from a sdcard. Only HTML file maybe shown.

The most simple solution of this task is to use an external PDF reader. Such approach it is convenient for users enough because a "hand made" PDF reader you create from a github open source code can be slow for displaying large pdf files.

public class PDFReader {
public void read(Activity context,  String fileName){
    File appFolder = new File( Environment.getExternalStorageDirectory(), 
        context.getBaseContext().getPackageName() );
    File file = new File(appFolder, fileName);

    Uri path = Uri.fromFile(file);
    Intent intent = new Intent(Intent.ACTION_VIEW);
    intent.setDataAndType(path, "application/pdf");
    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

    try {
        context.startActivity(intent);
    } 
    catch (ActivityNotFoundException e) {
        Toast.makeText(context, "На устройстве не найдено доступного приложения для отображения PDF!", 
            Toast.LENGTH_SHORT).show();
    }
}

}

he want to read pdf in webview not in default launcher. – Rohit Goswami May 20 '14 at 06:12 — Rohit Goswami, May 20 '14 at 06:12
