You can try the below cod snippet to load the .gif into webview:
Create a html file like this:
And store it in "assets" folder of you application also store your gif in the same folder. And do following to show it:
webview.loadUrl("file:///android_asset/your_html.html");
Other option is use the below lib.:

I want to load a webpage related files to a web view in my android application. I tried loading the webpage main html file(index.html) into the web view and it successfully loads. But the problem arises at the part where the other assets(like css files, images, js files) are not making it look like it should. Only the html part is loaded while other are left behind.
This is the output how is it looking like
Instead it should look like this
The rest of the assets files are not getting linked. Can anyone help?

I'm using Xamarin Forms with Android, I need to open a PDF from an URL in my WebView. For some reason, sometime the the Webview is blank. I've searched a lot on Internet and I found some solution that give me the same result, sometime the PDF in the PDF is showed without problem, sometime is a blank page. I'm using "https://drive.google.com/viewerng/viewer?embedded=true&url=" with no results, I'm using this solution ( https://acaliaro.wordpress.com/2017/11/30/open-a-pdf-inside-a-webview-in-xamarin-forms-android/ ) that describe exactly my problem but WebView still show me a blank page sometime.
So, why is so hard to open a PDF Url on Android in a WebView? There is some solution to fix this problem? I don't know what can i else do.
Android WebView not support .pdf file from website, infact, if you try to copy an url with .pdf extension in chrome browser, this will download the file and open in an app. So there is no way to show a PDF in an App in a simple way. But there are two solution:
On Google there are a lot solutions that tells you to download the PDF and show in an webview, but in my case I can't download a PDF and show.
You can write an .html page in your Server that can "wrap" the PDF sended with an URL in GET mode and show it in an .html page without problem ( using jsPDF is an example ) or by using this prefix ( http://drive.google.com/viewerng/viewer?embedded=true&url= ) but sometime i give a blank page, so i write my own pdf viewer. In this link ( https://acaliaro.wordpress.com/2017/11/30/open-a-pdf-inside-a-webview-in-xamarin-forms-android/ ) you can find another solution, but for some reason, it still doesn't works. Maybe because I'm on Android 5.0 device.
I have an app with a webpage called Avebury.html, and this has some javascript created by a colleague which loads a second HTML file inside it called widget. This has an iframe containing an embedded google map. Both are in the assets folder.
The problem is when trying to load Avebury.html in a webview it times out, and points to not being able to find the widget, when the link is correct.
I have tested linking straight to the widget and opening it in the webview, and it loads as it should. Both pages also work correctly in our iOS app and internet explorer.
The widget does take time to load, and I was wondering if the android webview is timing out the widget too soon, and if so is there a way to make it more lenient?
Thanks in advance.
I have found that android webview does not seam to like loading another HTML file from within the app in an iFrame. Removing the unneeded javascript and putting the iframe straight into the page bypassed the problem.
I have an app where I've button on a webpage that is rendered inside a webview.
Now on click of button , a pdf file gets downloaded , and the same would then need to be opened inside the same webview.
attach a download listener to the web view and change the url as follows..
"https://docs.google.com/gview?embedded=true&url=https://www.example.com/xxxxxyyyyyxz.pdf"
example
https://docs.google.com/gview?embedded=true&url=https://www.adobe.com/support/products/enterprise/knowledgecenter/media/c4611_sample_explain.pdf
it's a link used to open pdf without downloading it...
I hope it solves your problem..
I've found that the google viewer seems to work within the android browser for viewing online PDF files. You could build a link to your pdf so that it is displayed in the viewer. I've not tried doing that within a WebView though.
UPDATE
The link is dead, there is an explanation of how to get the functionality to still work at this link.
In case this link also dies, here is the relevant section:
While the page is no longer available as it redirects to Google Docs/Drive, you can still use the Google Docs Viewer. Paste this URL in a new tab:
https://docs.google.com/viewer?url=
and then paste the address of the document you want to view online. Here's an example:
https://docs.google.com/viewer?url=http://research.google.com/archive/bigtable-osdi06.pdf
I do not think that the present android chrome based browser can support pdf. There are discussion about the same in android forums ( ex: link1 link2)
Your best bet to show pdf is to have adobe pdf reader for android installed.(or concisely put, not possible in web view)
I don't think any browser other than Chrome supports rendering PDFs without a plugin or third party tool. It's probably easier to let the user use his own app to open PDFs.
I used the IText PDF library mentioned in this thread
Android : Is there any free PDF library for Android for a sample project. You could try getting using this API to get the PDF page as an image. I am not familiar with every aspect of Itext so it might have better way to do this.
