You are awsome, thank you. It was so easy to do this with your explanation. I managed to finish it from scratch in 2-3 hours, including finding myself installing Android Studio and the Emulator. Thank you so much.
@@bobbygraphics Thanks a lot. May be you can give me some heads up about the hardware requirements? I've set aside Android because it took like 5 minutes to recompile after every minor change. What is the preferred laptop configurations for this? I have MacAir with 8GB and I suspect there is something wrong about it not with configuration.. It should not be that demanding I guess...🙄🙄
@@alexeymatveev9031 I also have the same MacBook Air m1 base variant , and android studio is taking 3 gb of ram and the emulator is taking 5gb of ram and java is taking 1.5 gb of ram ! I don't know why it has such a high ram usuage!

Hi, First of all thank you for creating this project. I downloaded the project and tested. It has some bugs, When we minus 100-100 = It's giving wrong value as well as % isn't working. Please check once.
Well done your tutorial. There is one error. If you keep pressing the "C" key, an error called org.moailla.javascript.Undefined@o... will occur at the end. What could be the cause?
that has two reasons, one is using substring(0,0) may cause crash(so you need to change the "C" part, add an if statement), and the other is that setText("") does not cause "ERR", so you need to add something to the if statement in the filling resultTv part
ADD THIS In the case of "C" else if (button_text.equals("C")) { if(datatocalculate.length()==1) {datatocalculate="0";} else { datatocalculate = datatocalculate.substring(0, datatocalculate.length() - 1);} } it will work😇
Hi brother I am from Pakistan, When I press C button for multiple times and at the end when there is no value and I press C button then the application gets close automatically and I see the library name of JavaScript in Text view. Please provide the solution. Thanks
Any idea how to keep the exact precision when calculating? For example 6.1 multiplied by 3 results in 18.29999999999997. I guess it has something to do with the floating point numbers, but I can't figure out how to handle this problem in the code from this video... Apart from that - great tutorial! 👍
I once saw in a tutorial for addition of dollar. This error occurs because computers are poor in storing decimal number in form of binary. Convert 6.1 to 61 and 3 to 30. Multiply them , divide by 10. This should solve the issue. Simple and easy solution. Else you can always use relevant libraries in the language you are using.
Brother Could You Explain in depth About Rhino implementation u did in your project like the purpose of using script, context.setOptimizationLevel (-1) , In short, the whole portion of try. Eagerly Awaiting for your reply ! thanks :) Love Your Work :)
the function gets values between -1 to 9 and what it means is that higher levels of optimization can improve the performance of the JavaScript code but may also increase the time it takes to compile the code. So for this calculator simple app it really doesn't matter
Thanks bro I have created it for same like your work but the plus button just works other all not working like minus multiplay divide, please guide me how to solve it...
The parentheses doesn't work... And there is a problem where it shows 55 when you click 5=5(nn for n=n)...another problem is it shows Err if i press 5+= (n+=)

Thank you. There are minor problems, like if keeping pressing AC it goes below 0, but this is even better to solve as homework. Thank you very much!
Change if statement to while..so while ac is above 0. It must clear

@@atulthakur6928 were you able to solve it? I encountered the same.......solved to some sort but got another one.
ADD THIS In the case of "C"
else if (button_text.equals("C")) {

{datatocalculate="0";}
else {
datatocalculate = datatocalculate.substring(0, datatocalculate.length() - 1);}

Hi brother I am from Pakistan, When I press C button for multiple times and at the end when there is no value and I press C button then the application gets close automatically and I see the library name of JavaScript in Text view. Please provide the solution. Thanks
Yeah you can just add condition when there is no value.

second that
Use BigDecimal class rather than floating point numbers to get accurate values.
