In this video, learn how to make a calculator in Android Studio using Java. This calculator will be able to perform many functions like calculating exponentials, basic arithmetic, and you will also be able to use parentheses. All of this will be made possible through the use of a math parser called Mxparser. You will learn how you can download the Mxparser library and use it in your Android Studio projects.
We will be covering some of the core functions and techniques used for app development in Android Studio. This tutorial is designed for beginners trying to get started in app development with Android devices being the primary target.
Android Studio is a great platform for creating apps that can be deployed on the google play store. If you’re new to the series I’d go and check out the Android Studio Playlist. There you will be able to see how to create basic apps so you can become a developer.

Why is my button background did not change even though I did as you said? can you help me with this problem?
It's too good to learn…thank u

hello AndroidStudioProjects/Calculator/app/build/intermediates/incremental/mergeDebugResources/merged.dir/values-night-v8/values-night-v8.xml:14: error: resource color/black (aka com.firstapp.calculator:color/black) not found.
error: failed linking reference. when i try running my code, this shows. i dont know what i did wrong and none of my color are working. what should i do?
Nice
Still having troubles getting it borderless most everything else is working
Thankyou so much this is my first app ❤️
for some reason I don't know, setting the background attribute of my buttons won't change. The clue I noticed is it used the color of the background tint attribute instead because it said when I hovered in the background tint attribute, it showed default: @color/mtrl_btn_bg_color_selector. Does anyone know how to fix this?
So i did everything u said and the background on the buttons is not working.
i have the latest android studio version and the code i used in @drawable/circle was
<item>
<shape android:shape="rectangle">
<corners android:radius="1000dp"></corners>
<solid android:color="#263236"></solid>
</shape>
</item>
Could you help me out?
Sir can you give me all codes for diffrent color
pls
İ don’t have style in android
maybe to apply layout to all buttons can shift+click all the buttons until all selected then change with properties, is faster than code for each buttons ,i did this .. or if edit with code can try shift + alt +click the multiple lines for changes, btw thank you very much for the tutorial sir
Hi
The backgroundTint attribute does not change the color of the clear and equal buttons for me. They still have the blue color we defined in our circle.xml file. Can you please help?
Fucking love your channel. This is the first channel that sintesizes the information you need and goes straight to the point. If I could subscribe twice i'd do it. Keep going. You're gold, man.
I love the series so far but I have a problem. When I try to change the color of the background nothing happens. When I look at the attributes it says that it has the backgroundcolor but it doesn't show it. I hope you get what I try to say and that you can help me.

hi, i used the same color you did for the background. but after that i went to change the color, but it does not change the color in activity_main.xml. i delelted the circle.xml, and deleted all the lines under button, then again created the new circle.xml, and added the new lines to all the buttons, but it still takes the old color, which seems to be stuck in its memory. how to change to color of the background?
I cannot find the styles.xml file. Despite making the circle.xml file, I am not getting the round buttons. Can someone pls help me here?
thank you sir
what is your themes.xml file look like?
please make video on music player and gallery app
While running it's showing error in values.xml so please help to solve that
You can also control click all the buttons and change the button attributes at once by searching with the attribute name

I have a problem when I want to open the phone. I can wait for hours and the phone is still gonna be black. I press on the power button but its not working. Do you know how to solve it?
Hello, is it possible to use an image in every buttons? Like background image or something?, I have a laboratory exercise that we need to build a calculator in android studio, i havent use android studio yet but theres a criteria on the design, so i think i should exel more on the design since most of us will share the source code.
Hi, thanks for your helpful videos. I did try the same colour code #26328 but I got purple colour 🟣 and then i change the colours of clear and equal to red and green but still purple colour the code shows red dot and on the other green dot on front of the code. I don't know if the problem from the table layout or what. Because the colour work on backspace BTN only.
Excellent tutorial explaining the steps in continuous improvement with "why". I learned layout really well from this lecture.
Strg + Shift + Alt + J for multiple cursors at same selections really comes in handy in this tutorial.
When I use backgroundTint it doesn't update my preview. Also gives me a problem when running it
