I know this question has been asked many times and I have checked all the solutions and researched everything. However, this is simply not working for me.
I don't know what I am doing wrong. Can someone please help me out?
I am loading a local html file in my WebView and then calling the JavaScript function:
wv.loadUrl("file:///android_asset/sample.html");
wv.getSettings().setJavaScriptEnabled(true);
JavascriptInterface javasriptInterface = new JavascriptInterface(MyActivity.this);
wv.addJavascriptInterface(javasriptInterface, "MyInterface");
wv.loadUrl("javascript:loadpath()");
The HTML file is:
<html>
<head>
</head>
<body>
<script type="text/javascript">
function callDoSomething() {
// Do something
}
function loadpath() {
// Is not called no matter whatever operation I do here. Just printing a string, setting variable, android callback anything.
document.write("Hi");
document.getElementById('img').src = "path.png";
}
</script>
<form name="myForm" action="FORM">
<img src="" alt="Autofill" /><br>
<input type="button" value="Submit" onClick="callDoSomething()" />
</form>
</body>
</html>

Reset to default 6loadUrl() is asynchronous. You are calling your second loadUrl() way too soon. You need to wait until your page is loaded, perhaps by using a WebViewClient and watching for onPageFinished().
