Android-WebView显示pdf的加密内容

Question

I am developing an android application in which I tried to load pdf into Webview from the URL mentioned below,

http://ipAddress/SD_BIO/showDocument.jsp?fileName=HIPAA%20Authorization%20Form.pdf&attachmentType=STUDY_INFORMED_CONSENT_FORMS&attachmentTypeId=120&documentId=412

I tried in the following ways ,

((WebView) findViewById(R.id.pdf)).getSettings().setJavaScriptEnabled(
                true);

        ((WebView) findViewById(R.id.pdf)).getSettings().setAllowFileAccess(
                true);
        ((WebView) findViewById(R.id.pdf)).getSettings().setPluginState(
                PluginState.ON);
        ((WebView) findViewById(R.id.pdf))
                .loadUrl("http://ipAddress/SD_BIO/showDocument.jsp?fileName=HIPAA%20Authorization%20Form.pdf&attachmentType=STUDY_INFORMED_CONSENT_FORMS&attachmentTypeId=120&documentId=412");

The Webview is loaded , but encrypted like below,

Then I modified the loadURL like below,

((WebView) findViewById(R.id.pdf))
                .loadUrl("http://docs.google.com/gview?embedded=true&url=http://ipAddress1/SD_BIO/showDocument.jsp?fileName=HIPAA%20Authorization%20Form.pdf&attachmentType=STUDY_INFORMED_CONSENT_FORMS&attachmentTypeId=120&documentId=412");

But,it shows "No Preview Available" . Also,I could able to see some thirdparty libraries.But,client does not want any third party libraries .

Please help me find the solution .

Answer 1

WebView does not show PDF files. If http://ipAddress/SD_BIO/showDocument.jsp is returning a PDF file, WebView has no means of displaying it.

But,client does not want any third party libraries .

Your client does not have very many options:

• Use third-party PDF rendering code.

• Use a third-party PDF viewer app.

• Serve up something other than PDF, such as HTML.

• On Android 5.1+, try PdfRenderer , though that is really designed for print previews.

• Hire developers to write a custom PDF renderer from scratch (hundreds of developer-months' worth of work).
