Android : How to Load PDF? - android

Is there any way to load PDF file from Asset/URL in Browser or WebView or any other way?

There is no native way to do this at the moment. However, you could write your own pdf viewer activity. Also, check out RepliGo Reader and PDF GView.

Instead loading PDF file from local resource, you can think about open it online using Google Docs Viewer:
WebView webview = (WebView) findViewById(R.id.webview);
webview.getSettings().setJavaScriptEnabled(true);
String pdf = "http://www.adobe.com/devnet/acrobat/pdfs/pdf_open_parameters.pdf";
webview.loadUrl("http://docs.google.com/gview?embedded=true&url=" + pdf);

You can use pdf.js from Mozilla to display a PDF in a webview inside an Android application.
Here is the solution...

After searching a lot about this i came up with my own kind of solution
I used this website to convert my PDF to DOCX and then DOCX to HTML using online converters and then used the following code to load the HTML in my Webview.
String htmlString = "<p>YOUR HTML CODE</p>";
webView.loadData(htmlString, "text/html", "UTF-8");

android load local(in Asset/Res/External Storage) pdf file in webview

I want to display pdf file in webview.
I try using this code it displays blank page.
File retrieve perfacly but not display in webView.
Put screen shoot of webview displays webview when i run the application.
display blank webview. like this....
private WebView view;
Uri path;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
view = (WebView) findViewById(R.id.webView);
File file = new File(Environment.getExternalStorageDirectory()
.getAbsolutePath() + "/Documents/MyPDFFILE.pdf");
path = Uri.fromFile(file);
view.setContentDescription("application/pdf");
view.getSettings().setJavaScriptEnabled(true);
view.getSettings().setLoadsImagesAutomatically(true);
view.getSettings().setPluginsEnabled(true);
view.getSettings().setAppCacheEnabled(true);
view.loadUrl(path.toString());
// view.loadUrl("http://grail.cba.csuohio.edu/~matos/notes/cis-493/lecture-notes/Android-Chapter10-WebKit.pdf");
}
Because, Android WebView doesn't support PDF file functionality. And WebView cannot render PDFs.
The URL you posted on your comments it displayed pdf file in native web browser because of it uses Google Docs.
If you want to display pdf file in your webview then using Google Docs pass url of your pdf file which located on server not in your local.
Update:
Code for display pdf file located on net in webview.
WebView webview = (WebView) findViewById(R.id.webview);
webview.getSettings().setJavaScriptEnabled(true);
String pdf = "http://www.xxxx.com/xxxx/xxxx.pdf";
webview.loadUrl("http://docs.google.com/gview?embedded=true&url=" + pdf);

How to open a PDF file from server in android

I have a requirement where there is a URL = "http://www.example/Open.pdf"
Now from my android application I want to open this PDF file directly in the default PDF viewer.
The moment I click on this link on the webpage, user should be presented with a default PDF viewer opened with this document.
Note: This file should not be stored on the SD card.
How do I proceed for this implementation?
We can open PDF file in the webview without caching it. Write below code in "onCreate" method .
Working code :
String url = "http://www.example.com/abc.pdf";
final String googleDocsUrl = "http://docs.google.com/viewer?url=";
WebView mWebView=new WebView(this);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setPluginsEnabled(true);
mWebView.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url){
view.loadUrl(url);
return false; // then it is not handled by default action
}
});
mWebView.loadUrl((googleDocsUrl + url));
setContentView(mWebView);
What happens here is you open the PDF using Google Docs. Best Advantage of using above method is the lazy loading of PDF. Does not matter how heavy the PDF is. Google Docs takes care of it.
You can view the pdf in the WebView using googleDocs.
WebView webView = (WebView) findViewById(R.id.my_webview);
webView.setWebViewClient(new MyWebViewClient());
webView.addView(webView.getZoomControls());
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("http://docs.google.com/gview?embedded=true&url=http://myurl.com/demo.pdf");
There is no way you can open a default PDF view from your application.
If your file is on the server and you want to open it without downloading then this might also pose a greater security concern. If external applications like default adobe reader can access the content on your server, then this is breaking the security framework altogether.
So, best option would be to launch a new instance of browser or webview and show the PDF document in google docs to the user.
This way user can read the document and get back to the recent state of the application as well.
You can view the pdf in the WebView using googleDocs.
WebView webView = (WebView) findViewById(R.id.my_webview);
webView.setWebViewClient(new MyWebViewClient());
webView.addView(webView.getZoomControls());
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("http://docs.google.com/gview?embedded=true&url=http://myurl.com/demo.pdf");
do you have the others solution besides view pdf file using http://docs.google.com/gview?embedded=true&url=http://myurl.com/demo.pdf
