You are doing great for our community!!!

There is currently only third party applications for smartphones.

Using an IDE on a smartphone is never a good idea in my own opinion as it simply does not have the screen room and easy options for copy / paste etc.

BTW there is no reason to use all CAPS as that is considered as shouting but no doubt that was a limitation of using a smartphone.

There is support for CHROMEBOOK devices (not regular android tablets)

Trying to do any sort of decent project will always benefit from the use of a real computer.
Even a second hand dual core unit would give you much more options than a phone and access to a larger variety of software and arduino hardware.
