i'm trying application written in javafx ported across android , part have been successful in attempts. in application run on android after packaging apk file using netbeans ide , gradle.
but problem have application crash when trying access google map through javafx webview component. using following in javafx:
googlemapengine.load(getclass().getresource("/googlelondonmap.html").toexternalform()); and html file located under resources folder in gradle root folder.
when test application in netbeans right clicking on gradle root node , selecting tasks --> run --> run. application runs perfectly, including accessing google map using html file , javafx webview.
the creation of apk file successful in using tasks --> android --> android. once install apk file on android device , access google map portion of application throws me out of application saying "unfortunately has stopped". clues on how fix this?
looking @ log file created using adb command saw following output:

found cause fatal exception. appears android not following block of code:
url resource= getclass().getclassloader().getresource("music/thememusic.mp3"); themesong = new mediaplayer(new media(resource.tostring())); themesong.setonendofmedia(new runnable() { public void run() { themesong.seek(duration.zero); } }); themesong.play(); and block of code comes error message in android:
googlemapengine.load(getclass().getresource("/googlelondonmap.html").toexternalform()); webpage not available: webpage @ jar:file:/data/app/com.sundaethepugapp - 1/base .apk!/googlelondonmap.html not loaded because:
net::err_unknown_url_scheme
so can rectify this?
edit again
experimenting jose solution , building upon it, found way javascript in html working although ain't pretty. code supplied put method (called createandroidurlscheme) , returned string. here code , yes works fine in javafx, not in androids webview again:
string url = createandroidurlscheme("/googletestmap.html"); //system.out.println(url); googlemapengine.loadcontent(url, "text/html"); googlemapengine.setjavascriptenabled(true); googlemapengine.getloadworker().stateproperty().addlistener(new changelistener<worker.state>() { public void changed(final observablevalue<? extends worker.state> observablevalue, final state oldstate, final state newstate) { if (newstate == state.succeeded) { googlemapengine.executescript( "var latlng = new google.maps.latlng(59.438722, 24.745278);" + "var myoptions = {" + "zoom: 15," + "center: latlng," + "maptypeid: google.maps.maptypeid.roadmap," + "maptypecontrol: false," + "navigationcontrol: false," + "streetviewcontrol: false," + "backgroundcolor: '#666970'," + "disabledefaultui: true" + "};" + "" + "var map = new google.maps.map(document.getelementbyid('map_canvas'), myoptions);"); } } }); now through logcat new android fatal exception:

based on latest information provided, have 2 known issues:
media
if have @ this, media not supported yet, you'll need take out.
url scheme error
if have @ url showed error message, jar:file:/data/.../base.apk!/googlelondonmap.html, net::err_unknown_url_scheme means jar:file not known protocol on android.
the reason loading html file jar file not supported android sdk.
anyhow, resource accessible, workaround, load html file string , provide webengine using method loadcontent instead.
something should work:
stringwriter writer = new stringwriter(); bufferedreader reader = null; try { reader = new bufferedreader(new inputstreamreader(this.getclass().getresourceasstream("/googlelondonmap.html"))); string line = null; while ((line = reader.readline()) != null) { writer.append(line); } } catch (ioexception e) { e.printstacktrace(); } { if (reader != null) { try { reader.close(); } catch (ioexception e) { e.printstacktrace(); } } } engine.loadcontent(writer.tostring());
