Weather app

[Andrei]

Hello,  I would like to ask a question about a project I'm working on for college and I want to raise it to a higher level. I made a meteorological station based on an arduino mega which collects data by certain sensors then send them to me in the form of SMS. What I want to realize, it's an application for android that use the received SMS from the station and display them in an user friendly interface. I'm not good at programming and saw that App Inventor uses a drag and drop system which seems much simpler. How can I realize application, you can help me to establish its bases? I can handle the interface but the use of SMS is the most difficult. Thank you.

This MIT tutorial has features that you might modify to work in your app

Busy driving or in a meeting? Set this app to auto-respond to incoming texts by sending a reply text and also speaking the incoming text out loud.

What have you done so far?

Regards,

I saw the tutorial and I can use it. All I have to change is that depending on the message to change the data displayed. So far I've only made available interface and vectors for weather icon.

 But I have another question. How can I create a control like : If ... then ... else do nothing. I am interested about     else do nothing.

 If ... then ... else do nothing. I am interested about     else do nothing.

just use an if - then block

Thank typhoon, I solved that problem but I encountered another problem ... I know maybe it's silly but how do you display the characters inside "  ". 

[Taifun]

t how do you display the characters inside "  ". 

unfortunately I don't understand, you might want to elaborate...

you might find the parse procedure helpful

I will try to elaborate what I want to do. Arduino through a GSM shield it send me a message like this "Temperature=12 Pressure=1 Humidity=14 WindSpeed=4 WindDirection=SE" and I want to select only the results. At Temperature=12, I want to display in my screen 12, at Temperature=-16 to display -16. Therefore I used "contains text" to identify for example where Pressure is in the SMS then with a "segment text" to extract only the value after the = . In the image bellow I tried to do that, but it does not displays anything from position 8, length 2. ( In that SMS Grade="12" ).

See attached for how to do it.

Be careful to go back and add a blank to the one_space constant.  AI2 eats blanks.

Thank you ABG, I'm going to look at what you sent.
