How do I convert a program made on Notepad to my Arduino on Proteus
Besides displaying source code and letting you edit it, the IDE uses avr-gcc (and half a dozen other avr- utilities, like avr-objcopy, avr-ar, avr-nm) to compile and link the code and convert it to an elf or hex form, then uses avrdude to download it.  Using proteus, you can get by without  avrdude, but not without a suitable compiler and linker.

If you have a micro-SD slot on your phone, perhaps you can download the IDE to a card and then move the card to your computer to install the IDE.
