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.

file:/// works with test.html but without /mnt file:///data/data/com.example.android/files/Docs/test.html"); Still blank for pdf...
Use 5 / slashes like this file://///mnt/data/data/com.example.android/files/Docs/test.html
i added eclipse logs on top when i am trying to open a pdf file
unfortunatly, Webview does not support PDF in android. You will need to use google doc.
damned...can i invoke adobe reader in my app to display my pdf offline ?

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

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