In my local storage I have the following folder
/data/data/com.test.testapp/files/1/images
and the following file exists.
/data/data/com.test.testapp/files/1/images/f.png
These were stored/retrieved using context.getApplicationContext().getFilesDir()
In my HTML I have "<img src="f.png" />"
I can get TextView working with html/images using an ImageGetter, which effectively returns a drawable from:
Drawable.createFromPath(targetFile.getAbsolutePath());
Where the targetFile is as described above ends up being (/data/data/com.test.testapp/files/1/images/f.png)
However, when I try to use WebViewer as follows (I've pasted in the string for ease):
String url = "file:///data/data/com.test.testapp/files/1";
webViewer.loadDataWithBaseURL(url, content, "text/html", "utf-8", null);
Where content ends up with the same text as my TextView.
All I get is an image placeholder, i.e. it didn't find it.
OMG! ;)
How petty are those people at Google!
All I had to do was append a slash to the url so the base url:
file:///data/data/com.test.testapp/files/1
When changed to
file:///data/data/com.test.testapp/files/1/
Works.

Im making an app in which i show one wikipedia page, for testing im create a new project.
mvw.getSettings().setJavaScriptEnabled(true);
mvw.getSettings().setLoadsImagesAutomatically(true);
mvw.getSettings().setAllowContentAccess(true);
mvw.getSettings().setDomStorageEnabled(true);
mvw.setWebViewClient(new mostrarEnAplicaion());
String htmlString = "<!DOCTYPE html><html><body style = \"text-align:center\"><img src=\"https://en.wikipedia.org/?curid=52633874#/media/File:Wat_Phra_Mahathat_Woramahawihan,_Nakhon_Si_Thammarat.jpg\" alt=\"pageNo\" height=\"100%\" width=\"100%\"></body></html>";
mvw.loadDataWithBaseURL(null,htmlString,"text/html","UTF-8","about:blank");
If I load the URL directly works fine
mvw.loadUrl("https://en.wikipedia.org/wiki/Santa_Mar%C3%ADa_del_Naranco");
I have the permission.INTERNET on the Manifest but doesnt work, anyone know the solution?
After look for a while, I just see that in this line
mvw.loadDataWithBaseURL(null,htmlString,"text/html","UTF-8","about:blank");
I only have to change the null (BaseUrl) for the url of the website in which the images are storage, in this case "https://en.wikipedia.org/"
I would like to know if one of your could embed GIFV format into your app. I am trying to embed it using a webview but without success.
Actually GIFV format is closer to a video format than a gif.
Whatever suggestion would be nice. Thanks in advance.
After work around of this issue, I couldn't find a solution which could display GIFV format like a video.
But, my solution to this issue has been to use a webview using the same way that i was using to make able to load "gif" files and if you remove directly the "v" from the name of the file, you can show it as a .gif file.
Resuming, remove the "v" from the .gifv file name and display it as a .gif.
The way that i am injecting code to make able to display gifs into the webview is:
public void getContentWebView(String url, WebView webView)
{
String html = "<!DOCTYPE html><html><body><img src=\""+ url +"\" width=\"100%\" height=\"100%\"></body></html>";
webView.loadData(html, "text/html", "utf-8");
}
I have some html content which has to be displayed on android webview. Here is my code to display the content on webview
myBrowser.loadDataWithBaseURL("", myFormHTMLContent , "text/html", "UTF-8", null);
I have few img tags in html content. How can i specify the src for those? I tried this .. src = "/mnt/sdcard/myDir/test.gif". But its not loading that image. Please help me.
Try this.
src = Environment.getExternalStorageDirectory().getPath()+"myDir/test.gif"
I would like to set some html content in my webview with some pictures.
I've read on the internet i must use loadDataWithBaseUrl to do such a thing because i need to link the folder of images (basUrl) in order.
My html content nicely loads, i can even ran the javascripts perfectly, but for some reason my images cannot be loaded.
Somewhere i've read there are some security reasons and thats why i cant load images from sd card to webview and some says it can be easily done via loadDataWithBaseUrl, so i really dont know which one is true.
Here is my method i tried, maybe with some mistakes so dont be rude:
I got my html file here:
mnt/sdcard/com.mypackage.myproject/3/3.html
My images are here:
mnt/sdcard/com.mypackage.myproject/3/images/Cover.png
And this is my content loading:
myWebView.loadDataWithBaseURL("file:///mnt/sdcard/com.mypackage.myproject/3", myHtml, "text/html", "utf-8", "");
In my html code:
<img src="images/Cover.png" alt="Cover.png" height="820"/>
So as you see i give the baseUrl, and for some reason the webview cannot load my images.
As many said, this can be a solution:
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setAllowFileAccess(true);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setBuiltInZoomControls(true);
String base = Environment.getExternalStorageDirectory().getAbsolutePath().toString();
String imagePath = "file:/"+ base + "/test.jpg";
String html = "<html><head></head><body><img src=\""+ imagePath + "\"></body></html>";
mWebView.loadData(html, "text/html","utf-8");
BUT, i have 700 different html files and there are many images in many different places... so i cannot modify the html code.
Is there a way to link the image folder to my html files to properly use them as a baseUrl?
You have a syntax error in your loading statement. You have to put : after file
myWebView.loadDataWithBaseURL("file:///mnt/sdcard/com.mypackage.myproject/3", myHtml, "text/html", "utf-8", "");
You don't need to put full path of your image into html.
img src="images/test1.jpg"
Instead
img src=\""+ imagePath + "\"
Please help me solve this file path conflict:
As you know, many HTML pages use relative paths starting with a "/" for the href attribute of link tags. For example: link href="/links/style.css".
In my code, I'm using loadDataWithBaseURL for a WebView to set a relative path name. If I give like this:
String webContent=//whole html page;
mWebView.loadDataWithBaseURL("file:///sdcard/mibook/pg90/",new String(webContent), "text/html", "UTF-8","" );
Result: No effect in WebView because (I felt) it takes two '/' while appending to pathname.
If I edit my HTML page by removing the first "/" from the href tag, then the WebView renders properly.
But my problem is that I don't want to edit HTML content as above. Any solution?
Javadoc of loadDataWithBaseURL states:
Note for post 1.0. Due to the change in the WebKit, the access to asset files through
"file:///android_asset/" for the sub resources is more restricted. If you provide null
or empty string as baseUrl, you won't be able to access asset files. If the baseUrl is
anything other than http(s)/ftp(s)/about/javascript as scheme, you can access asset
files for sub resources
So basically only allowed URL for file:/// scheme is file:///android_asset/ where files are in your asset folder.
