OneSignal - help me open URL within existing webView ... I'm so confused
I had someone create a very basic WebView app for me which has OneSignal notifications. The app launches with a splash screen and then two buttons on the main page that sends users to different URL's - in my example below, Google and Stack Overflow.
It's working fine but I'm trying to make changes to open a specific URL when a notification is tapped and can't workout how, despite lots of reading here and the OneSignal documentation. As a last resort, I thought I would post my code to see if anyone can help this newbiew to app coding !
Basically, I need to fix the launchURL code at the very bottom in the ExampleNotificationOpenedHandler class. I'm sending the URL as additional data via OneSignal and the app reads it correctly in the launchURL variable (when I view the logcat).
public class App extends Activity {
private static final String WEB_URL1 = "https://google.com";
private static final String WEB_URL2 = "https://stackoverflow.com";
View ll_Web;
WebView webView;
SwipeRefreshLayout mSwipeRefreshLayout;
RelativeLayout splash, home;
View ll_pView, pView;

For the benefit of others searching for a similar issue, my working code is below. As a novice, I'm not sure if it's the best solution but it's working for me with the testing I've been doing.
Thanks again to @nimi_moradi for the advice which helped me solve my issue.
class ExampleNotificationOpenedHandler implements OneSignal.NotificationOpenedHandler {
// This fires when a notification is opened by tapping on it and
// puts the launchURL additional data into a string for use in the main activity
public static String launchURL;
@Override
public void notificationOpened(OSNotificationOpenResult result) {
OSNotificationAction.ActionType actionType = result.action.type;
JSONObject data = result.notification.payload.additionalData;
//public String launchURL;
if (data != null) {
launchURL = data.optString("launchURL");
if (launchURL != null) {
// Log.i("OneSignalExample", "launchURL value: " + launchURL);
}
}
}
}

do it like you with button
if (launchURL != null) {
Log.i("OneSignalExample", "launchURL value: " + launchURL);
webView.clearHistory();
webView.loadUrl(launchURL);
home.setVisibility(View.GONE);
ll_Web.setVisibility(View.VISIBLE);
}
i think webview is not created when set url for it , add action listener in onStart if you can
@Override
protected void onStart()
{
super.onStart();
OneSignal.startInit(this)
.setNotificationOpenedHandler(new ExampleNotificationOpenedHandler())
.init();
}
}
or at least after setContentView(R.layout.main);
like here
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
OneSignal.startInit(this)
.setNotificationOpenedHandler(new
ExampleNotificationOpenedHandler())
.init();
