jquery prob in WebView of Android 4.4

636 views Asked by At

I have loaded a webpage in thw WebView and inject jquery and my js file from my asset fole to that webpage. My code is below in short.

MainActivity.java

mWebView.loadUrl("www.test.com/test.html");
mWebView.loadUrl("javascript: " + readFromfile("jquery-1.8.3.js", MainActivity.this));
mWebView.loadUrl("javascript: " + readFromfile("my_android.js", MainActivity.this));

.....................

mWebView.loadUrl("javascript: myMethod();");

my_android.js

function myMethod(){
...............
var mySpan = $("<span id=\"myspan\"></span>");
................
}

This is running fine in pre-Kitkat. But it is giving error in Kitkat. When it is loading the JS, it is giving error:

I/chromium﹕ [INFO:CONSOLE(1)] "Uncaught ReferenceError: varrootjQuery is not defined"

When I am calling the js function, it is giving:

$ is not defined

What is the problem in my code? Here I like to mention all webview related code are running in UI thread only.

I think you just need to wait jquery is loaded before use it.
