Menu
I am using following MathJax app code. http://cs.jsu.edu/wordpress/?p=498#comment-217
In following function i am trying to load file from asset directory.
public static boolean makeMathView_new(WebView webview) {
webview.getSettings().setRenderPriority(RenderPriority.HIGH);
webview.getSettings().setJavaScriptEnabled(true);
webview.loadDataWithBaseURL("http://bar", "<script type='text/x-mathjax-config'>"
+"MathJax.Hub.Config({ messageStyle: 'none', showMathMenu: false, jax: ['input/TeX','output/HTML-CSS'], "
+"extensions: ['tex2jax.js'],"
+ "'HTML-CSS': { scale: 100 },"
+"TeX: { extensions: ['AMSmath.js','AMSsymbols.js','noErrors.js','noUndefined.js'] } });</script>"
+"<script type='text/javascript' src='file:///android_asset/MathJax/MathJax.js'></script>"
+ "<span id='math'></span>","text/html","utf-8", "");
return true;
}
When running on android 4.4 emulator, I am getting following errors.

Update: After incorporating ksasq's suggestion , Here is my new code but it is still not working.
webview.loadDataWithBaseURL("http://bar", "<script type='text/x-mathjax-config'>"
+ "function setupMathJax() {"
+ "MathJax.Hub.Config({ messageStyle: 'none', showMathMenu: false, jax: ['input/TeX','output/HTML-CSS'], "

+ "}"
+ "</script>"
+ "<script type='text/javascript' src='file:///android_asset/MathJax/MathJax.js'></script>"
+ "<body onload='setupMathJax()'>"
+ "<span id='math'></span>"
+ "</body>"
,"text/html","utf-8", "");

You have to replace all the lines loadUrl(...) with evaluateJavascript(...). But this is only for KitKat (API 19 or above), so you need to do an SDK version check first:
if (android.os.Build.VERSION.SDK_INT < 19) {
mWebView.loadUrl("javascript:MathJax.Hub.Queue(['Typeset',MathJax.Hub]);");
} else {
mWebView.evaluateJavascript("javascript:MathJax.Hub.Queue(['Typeset',MathJax.Hub]);",null);
}
if (android.os.Build.VERSION.SDK_INT < 19) {
v.loadUrl(url);
} else {
v.evaluateJavascript(url,null);
}
