Android Question Is it possible to make with B4A

[bokinet]

I have to make small android app which will query a web server over http/https and get reply from it as json type formatted respond from server.
If respond status is ok then I need to send a SMS message which can be multi-part text based message (longer then 160 chars sometimes) to recipient.
Recipient (mobile phone number) can be different each time.

Main concern and question is:

Is it possible to use B4A to make such app which will do this and work in background?

Android device will be used only for this use and will be all the time connected on power 24x7.
This also means that it will not be any other user activates on this android device.

Something like automated machine and notification system and replacement for combination of regular PC workstation and GSM modem for such things.

Extra question for this is, since I know for issue regarding to Message app and Android OS (that only Messages app can delete (write) messages), is there any way to delete messages or purge them automated even after some time because of memory? I mean for sent ones?

Thanks.

Yes to the first question and Yes to the second question.

Obviously it is complicated to do it, but much less to do it with Android Studio.

I hope I have helped you

If I understand you well, so it's possible to make with B4A or miss something?

Which tool you would use for this? B4A or Android Studio?

Thanks.

Doesn't sound too complicated. All features are supported by B4A.

@Erel
It's better to ask before start doing things
Anyway it's left me to resolve purging of sms messages which was sent to save storage memory.
By looking your samples and some of your video tutorials guess issue is still deleting sms messages

The stored messages are unlikely to cause any issue.

However you can make your app the default SMS app and the messages will not be added to the SMS store. It requires some code to be added to the manifest editor (should be available in the forum).

I found some app (name SMS Organizer) on Google Play store and try. It has a part in which you define rules to apply on sms which comes/goes in/out.

And yes as you say that app should default sms app.

But I tried in combination with code for sending messages from B4A and i found out that after you run Messages app (which was stock sms app), messages will stay on device even if they are deleted from SMS Organizer app.

So, in short issue is if you after you setting up def. app to your own app as sms def. app run again messages app - then sms will remain on device even if you delete - actually then they are not permanently delete.

I was testing all this on Android 6.0.1 using Nexus 5 device.

If you have any specific question then you should start a new thread.

i searched now on forum for sms deleting and guess it is a still open and under question solution for doing it for android os newer then version 4.4
So what is a point to ask when old ones are still under question
Guess should investigate a bit about it.

Not true. There is nothing open.

If you have any specific question then you should start a new thread.
