I'm trying to use javascript interface along with google maps javascript library.
I searched and i found a way almost all similar to this JavascriptInterface .
This is my code :
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp"></script>
<script type="text/javascript">
function testAPI() {
JSInterface.test();
}
</script>
<script>
// gooogle maps code
//
</script>
</head>
<body>
<div id="map-canvas"></div>
<div><input type="button" value="Make Toast" onClick="testAPI()" /></div>
This is my interface :
public class JavaScriptInterface {
private Activity activity;
public JavaScriptInterface(Activity activiy) {
this.activity = activiy;
}
public void test(){
Toast.makeText(activity.getApplicationContext(),
"Javascript interface test.", 0).show();
}
}
This is where i create all :
myBrowser = (WebView) findViewById(R.id.mybrowser);
myBrowser.setWebChromeClient(new WebChromeClient() {
public void onGeolocationPermissionsShowPrompt(String origin,
GeolocationPermissions.Callback callback) {
callback.invoke(origin, true, false);
}
});
myBrowser.getSettings().setJavaScriptEnabled(true);
String javascrips = null;
// myBrowser.loadUrl("file:///android_asset/geolocation.html");
try {
AssetManager am = getAssets();
InputStream input = am.open("geolocation.html");
int size;
size = input.available();
byte[] buffer = new byte[size];
input.read(buffer);
input.close();
javascrips = new String(buffer);
} catch (IOException e) {
e.printStackTrace();
}
jsInterface = new JavaScriptInterface(this);
myBrowser.addJavascriptInterface(jsInterface, "JSInterface");
myBrowser.loadDataWithBaseURL("file:///android_res/raw/", javascrips,
"text/html", "UTF-8", null);
When clicking on the button (the javascript input with the testAPI() function ) , nothing happens , The Toast doesn't not show up why ?
