Wikitude

Hi, I have a Cordova android app with the SDK for AR recognization and I am experiencing unexpected app crash. 

I'm currently using Cordova CLI v9.0.0

cordova-android 7.1.4

cordova-plugin-compat 1.2.0 "Compat"

cordova-plugin-device 2.0.2 "Device"

cordova-plugin-file 6.0.1 "File"

cordova-plugin-file-opener2 2.2.0 "File Opener2"

cordova-plugin-file-transfer 1.7.1 "File Transfer"

cordova-plugin-geolocation 4.0.1 "Geolocation"

cordova-plugin-inappbrowser 3.0.0 "InAppBrowser"

cordova-plugin-nativestorage 2.3.2 "NativeStorage"

cordova-plugin-navigationbar-color 0.0.8 "NavigationBar"

cordova-plugin-network-information 2.0.1 "Network Information"

cordova-plugin-screen-orientation 3.0.1 "Screen Orientation"

cordova-plugin-statusbar 2.4.2 "StatusBar"

cordova-plugin-whitelist 1.3.3 "Whitelist"

cordova-plugin-zip 3.1.0 "cordova-plugin-zip"

es6-promise-plugin 4.2.2 "Promise"

com.wikitude.phonegap.WikitudePlugin v 8.3.0

The problem seems to appear randomly and seems to fix itself after closing and cleaning the app cache. I have tested various cases and my finding are:

- uninstall app

- install app

- open app and enter the ar mode

- after the ar mode is loaded I scan an element and it is recognized correctely

- close the app without exiting the view

- reopen app

- after the ar mode is loaded I scan an element and it is recognized correctely

- close the app without exiting the view

- reopen app

- after the ar mode is loaded I scan an element and it is not recognized

- close the app without exiting the view

- reopen app

- after the ar mode is loaded I scan an element and it is recognized correctely

Other test follow for every time I open the app are:

- loading / scanning of element ok

- loading / scanning of element don't show anything (didn't find the image) but didn't go in crash. in this scenario i usually go back in the menu and restart the ar mode

- loading / scanning of element result in crash of the app. in this case the app remain opened in background, so i close and reopen it

As you can see the sequence of crash is random and I can't find a cause to this behavior.

Thanks in advance for the support in fixing this problem of mine.

Hi,

I'm trying to get the sample app to load the first option but I'm stuck at this point in index.js file

I have placed several alert to get the point in which the code "freeze" but I can't get why it get stuck

prepareArchitectWorld: function(architectWorld, successCallback) {

    alert(7); // Here enter

    app.wikitudePlugin.isDeviceSupported(function() {

        alert(8); // Don't enter

        app.wikitudePlugin.requestAccess(

            function() {

                successCallback();

            },

            function(error) {

                var openAppSettings = confirm(error.userDescription + '\nOpen App Settings?');

                if ( openAppSettings == true ) {

                    app.wikitudePlugin.openAppSettings();

                }

            },

            architectWorld.requiredFeatures);

    }, function(errorMessage) {

        alert(13);

        app.wikitudePlugin.showAlert(errorMessage);

    },

    architectWorld.requiredFeatures);

    // Don't get here, stop before

    alert(12);

}

For the loggin of my app, is there a logging method internal of the wikitude plugin because the only log i can get are the one i implement and they aren't helpful.

Correct me if I'm wrong but I only use the Cordova extension or am to use other as well?

Hi, I would like a response on the information sended two days ago, in particular I would like to know your opinion on the four video that shown my app with the wikitude plugin at work in different situation of incorrect behaviors. I confirm the availability to provide the apk for your possible tests.

Regarding the sample app I would like some help because I don't have know how to set that up, the log for the actual app I'm blocked because I can't seem to get anything usefull.

I have started the sample app like in the following screenshot, but now I don't know how its supposed to work, clicking the various submenu like 1.1 don't do anything, I need to insert a world url perhaps?

I can, if its of any help, upload the apk of the app
