Android phonegap app is slow
Question
I have a html5/phonegap application. It runs slow on galaxy s3 or s4.
The logcat shows it has some 2-second delay here and there. Below are some examples.
05-19 12:30:27.148: D/webkit(14438): euler: isUrlBlocked = false
05-19 12:30:29.390: D/dalvikvm(14438): GC_FOR_ALLOC freed 1641K, 22% free 26652K/33832K, paused 18ms, total 19ms
...
05-19 12:30:30.331: D/webkit(14438): euler: isUrlBlocked = false
05-19 12:30:33.024: V/chromium_net(14438): external/chromium/net/socket/ssl_client_socket_openssl.cc:419: [0519/123033:INFO:ssl_client_socket_openssl.cc(419)] ~SSLClientSocketOpenSSL()
Any suggestions? Or any way to find out more details?

yep i also faced the same problem when developing my first Android Calculator. the problem is with all the CSS . if you have coded a lot of CSS and a lot of references. it will stuck in it.
or you can try to write all the CSS using inline method. and same with JavaScript like,
<html>
<head>
<title>Html calculator</title>
<style type="text/css" >
body{
background-color: #A7A6CC;
}
#bt{
height:80px;
width:80px;
font-size:40px;
background:#8987BA;
}
#ans{
height:50px;
background:#8987BA;
font-size: 30px;
}
#main{
text-align:center;
}
</style>
</head>
<body >
<table id="main" align="center">
<tr>
<td>
<form name="calculator" >
<input id="ans" style="width: 320px;" type="textfield" name="ans" value="">
<br>
<input id="bt" type="button" value="1" onClick="document.calculator.ans.value+='1'">
<input id="bt" type="button" value="2" onClick="document.calculator.ans.value+='2'">
<input id="bt" type="button" value="3" onClick="document.calculator.ans.value+='3'">
<input id="bt" type="button" value="+" onClick="document.calculator.ans.value+='+'">
<br>
<input id="bt" type="button" value="4" onClick="document.calculator.ans.value+='4'">
<input id="bt" type="button" value="5" onClick="document.calculator.ans.value+='5'">
<input id="bt" type="button" value="6" onClick="document.calculator.ans.value+='6'">
<input id="bt" type="button" value="-" onClick="document.calculator.ans.value+='-'">
<br>
<input id="bt" type="button" value="7" onClick="document.calculator.ans.value+='7'">
<input id="bt" type="button" value="8" onClick="document.calculator.ans.value+='8'">
<input id="bt" type="button" value="9" onClick="document.calculator.ans.value+='9'">
<input id="bt" type="button" value="x" onClick="document.calculator.ans.value+='*'">
<br>
<input id="bt" type="button" value="0" onClick="document.calculator.ans.value+='0'">
<input id="bt" type="reset" value="Reset">
<input id="bt" type="button" value="=" onClick="document.calculator.ans.value=eval(document.calculator.ans.value)">
<input id="bt" type="button" value="÷" onClick="document.calculator.ans.value+='/'">
</form>
</td>
</tr>
