I have a simple WebViewClient for my WebView and am overriding shouldInterceptRequest: (Not actual code)
public class WebViewClientBook extends WebViewClient
{
@Override
public WebResourceResponse shouldInterceptRequest(WebView view, String url)
{
File file = new File("pathToTheFile.jpeg");
FileInputStream inputStream = new FileInputStream(file);
return new WebResourceResponse("image/jpeg", "UTF-8", inputStream);
}
}
For some reason, the WebClient is unable to display the image... I believe it might have something to do with an incorrect encoding: UTF-8.
Any suggestions what to use as an alternative?
Thanks!

You are doing it wrong. You have 2 ways to do it, and it depends on what is receiving that image.
Case 1: You want to return a byte array. In this case, you should have a Javascript treating it and parsing it into a string and assign it to the src field of your tag on the webView.
File imagefile = new File(otherPath);
FileInputStream fis = null;
try {
fis = new FileInputStream(imagefile);
finall = fis;
} catch (FileNotFoundException e) {
e.printStackTrace();
}
Bitmap bi = BitmapFactory.decodeStream(fis);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
//PNG OR THE FORMAT YOU WANT
bi.compress(Bitmap.CompressFormat.PNG, 100, baos);
byte[] data = baos.toByteArray();
InputStream is = new ByteArrayInputStream(finaldata);
return new WebResourceResponse("text/html", "UTF-8", is);
Case 2: You parse everything on the Activity and pass the full html code so in the webView you will have a which innerHTML property will be updated with this data.
File imagefile = new File(otherPath);
FileInputStream fis = null;
try {
fis = new FileInputStream(imagefile);
finall = fis;
} catch (FileNotFoundException e) {
e.printStackTrace();
}
Bitmap bi = BitmapFactory.decodeStream(fis);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
//PNG OR THE FORMAT YOU WANT
bi.compress(Bitmap.CompressFormat.PNG, 100, baos);
byte[] data = baos.toByteArray();
String image64 = Base64.encodeToString(data, Base64.DEFAULT);
String customHtml = "<html><body><h1>Hello, WebView</h1>" +
"<h2><img src=\"data:image/jpeg;base64," + image64 + "\" /></img></h2></body></html>";
InputStream is = new ByteArrayInputStream(finaldata);
return new WebResourceResponse("text/html", "UTF-8", is);
In case you just want to load the image you can always do a webView.loadData(String data, String mimeType, String encoding)
Hope it helps, I just got mine working with this
