Hola Juan,

No tiene que ver con App Builder ni con Apache Cordova... Si no me equivoco, tiene que abrir el Android SDK Manager (una forma de hacerlo es mediante CTRL + R, escribiendo luego "android", pero, tal vez esto no sirva en su sistema: en todo caso debe hacer lo dicho: abrir, ejecutar, acceder al Android SDK Manager, acaso desde algún menú de Android Studio si el comando "android" mencionado no se reconoce en su sistema) y actualizar lo necesario o en todo caso "aceptar la licencia" de alguno de los paquetes que se le muestren.´

Si está tratando de usar algún plugin de Apache Cordova... tal vez este plugin necesite algunos paquetes en concreto disponibles (instalados) desde el Android SDK Manager. En todo caso el error en concreto no parece ese, sino que alguno de los paquetes disponibles ha debido actualizarse o algo así y es preciso "aceptar su licencia" de nuevo... o por primera vez...

Hello John,

I need to investigate a bit more when possible, since the sample works as expected in all the browsers that I try, not only in Chrome. What I see now, is that, for some reason I can't understand, we can't use jQuery to change the browser's pages color (like the sample want to do).

I am not sure if it's a question of permissions or what, since I discover that removing the jQuery lines and place a couple of "alerts" in their place, the sample working as expected, that is, the WebExtension receive the messages that we send, and even we can receive a message from the WebExtension context.

Even more, if we try something like this: "document.body.style.fontSize = '150%';", we can see it working as expected, so, it's quite rare why jQuery is not allowed... or working as expected... and I want to take a look at this when possible, John.

Hello Amin,

Thanks for your consideration. Certainly I don't provide too much help... maybe in the future. Maybe other mate know about a possible server websocket software to be used. I think that can be more or less easy to find information... following the above link... or just searching by something like "Java server websocket implementation"...

In fact it's rare that no one already exists... but I can't recommend one of them as I wanted... I am wrong... I figure out that we are using some specific software, but, no... we develop the websocket sever from the scratch. Maybe this can give us some information... probably it's not very, very difficult or complex to start with it... of course later the software can become more complex: database queries, etc., but, probably start with it (using Java, Glasfish, etc.) maybe it's not very, very complex at all...

What I mean is that probably I am missing something... for example, maybe a websocket server is in fact an HTTP server with some kind of particular configuration or something like that? That's what I start to think and what I want to say here...

Hello Amin,

First of all, please, sorry for the delay. Believe or not, I am working very hard in certain app these days and I have no time to write a reply! In fact that's the app in which we are using a websocket server for the app's chat and other features.

I have a problem, because, I am the responsible for the client side (working with AB), but not the server side. I ask yesterday to my boss (which is responsible for the server side, among other team members), about the websocket software that we are using: I really think that we use certain specific software, but, my boss told me we are not doing that.

When I ask about the software in the server he told me we use Java "glasfish", which is an "app server" similar than Java "TOMCAT". So it's "glasfish" who launch, execute or maintain the websocket server... WHICH HAS BEEN WRITTEN FROM THE SCRATCH... my boss offer to me this forum thread, in which apparently they base to prepare the websocket server.

And that's all what I can say... except if you want to ask something in particular: in this case I will try to find the right answer or directly reply if possible. No; not too much information, I know, Amin, but you must look for some possible "sample Java websocket server", follow the referred forum link, maybe it's possible to use some software which already offer to us what we need...

The client site (with AB) is more easy... requires their work, of course (I can remember when we develop the chat...), but what we must do is to use the WebSocket control, and, mainly, their Message event. Basically the server can send anything to the app... and viceversa, we commonly use JSON objects to transfer data, which appear very good, since a sole object can have several properties and values.

That's all for now, Amin... not too much help... but maybe we can continue ahead here or in other posts.

Hello John,

If the sample can be useful for you that's the point! :-)

Hello Amin,

If with "notifications" you mean push notifications... note that they works like a charm, but, not always in real time... because the notification is finally sended by the thirdparty service that we use, like Google FCM. Or maybe I am a bit wrong and you mean other thing but not exactly push notifications... or there is not a problem to receive that notifications "not in real time" (even when sometimes... they arrive in a merelly real time).

Hello John,

You place a non too much specific question, that is, something like "I am trying this and this other but I expect this result and get this error message..."... It's possible to do something like you wanted using a bit of Javascript, and, one of the ways in which we can think is what you can see in the below app sample:

Save the above code in a file and save it as "MyApp.ab", for example. Before open the file with DecSoft App Builder, look in your computer for a PNG image and copy it aside the "MyApp.ab" file with the name: "butterfly.png". Now yes, open "MyApp.ab" with DecSoft App Builder and run the app.

As you can see, every time you click the view (and the app, since we use the scale app option), the butterfly appear in the position that you clicked.

No problem, Peter! :-)

Hello Peter,

Yes; I think you need the IfEx action...

Hello to all,

I think in your last post you are talking about some possible scenarios of the app, which of course you may need to control. In other words, the app must be ready to work in different scenarios, like what you describe using questions: "So what if one them don't deliver, or delivers 1-2 seconds late?" I supose that things like that must be implemented in an app level, that is, it's a question of the app's implementation. Am not saying that this all are easy, of course... just that maybe it's a question of think about, work on it, etc. Step by step, question by question...

Yes; again my help try are not very useful at all... but is what I can say right now: supose a bad connection scenario... then your server hardware can't do nothing,... so in my opinion it's the app who must control that kind of possible scenarios... in order to maintain the things working... at least in the best way as possible.

Hello Ade,

Apparently Apache Cordova can produce right now 64 bits apps for Android: the only "problem" can appear if any of our used Apache Cordova's plugins don't support Android 64 bits, so, in fact depend on the app that we are development and the plugins that we are using on that. If the plugins are ok, then our apps are apparently ok too for the Android 64 bits.

Hello Ade,

I am not sure if there is any issue... by default, the min SDK target is already Android 4.4 and the API level 19. Other options may must continue existing... to be used if needed, maybe not with the newest version of Apache Cordova, but with older ones, again, if we need something like that.

Hello to all,

Here is a new DecSoft App Builder release, with the below changes, fixes and enhancements:

Hello John,

We can try to see what can be the cause if your work computer anyway... but I am not sure how to help you right now! :-(

Hello John,

Your code it's quite curious, since, in principle, the DropDown controls expected a non associative Array: you provide an associative Array, so the control take the key's values. Maybe other do the things in other way, but, your code works as expected too.

About your concern, certainly you are not exactly set the value of the AB controls. Do that it's just replace one line of your code:

Doing that you can therefore access to the controls' "Value" variables like always.
