Can't open a local PDF in webview using file://

I need to display a PDF file located in my app dir in a webwiev without using Google Docs.

This is my code for the webview:

public void OpenPDF() {
WebView webview = new WebView(this); 
    setContentView(webview);
    webview.getSettings().setJavaScriptEnabled(true); 
    webview.loadUrl("file://mnt/data/data/com.example.android/files/Docs/test.pdf");;
}

I get a blank webview instead of below code works

public void OpenPDF() {
WebView webview = new WebView(this); 
    setContentView(webview);
    webview.getSettings().setJavaScriptEnabled(true); 
    webview.loadUrl("file://mnt/data/data/com.example.android/files/Docs/test.html");  
}

I tested directly in my web browser with file://mnt/data/data/com.example.android/files/Docs/test.pdf and test.html and it worked for both. I installed a PDF reader.

Their seems to be an answer to your question already in stack overflow at Open Local Html File in Webview - Android

to sum it up : Usage of file:/// before your actual path should solve your problem for everything except .pdf files

Webview does not support PDF in android :(. You need to use google doc according to different sources.

I think you should try with 3 slashes, like that:

webview.loadUrl("file:///mnt/data/data/com.example.android/files/Docs/test.pdf");
