Question

How to add JQuery library into page loaded in Android WebView? My WebView with page:

 webview.getSettings().setJavaScriptEnabled(true);
 webview.loadUrl(url);

Answer 1

I had to remove escapes from js code (like \n). Also I had to wait untill JQuery is loaded:

load.tryReady = function(time_elapsed) {  
   // Continually polls to see if jQuery is loaded.  
   if (typeof $ == "undefined") { // if jQuery isn't loaded yet...  
       if (time_elapsed <= 5000) { // and we havn't given up trying...  
           setTimeout("load.tryReady(" + (time_elapsed + 200) + ")", 200); // set a timer to check again in 200 ms.  
       } else {  
           alert("Timed out while loading jQuery.")  
       }  
   } else {  
      // Any code to run after jQuery loads goes here!  
   }  
}
