Is it possible to develop an android application with only an android tablet at hand?

Question

Android

If possible, which is better to use: development applications or online services?

Answer 1

You can develop without a single device at all.
Another thing is that without proper testing, it is not known how your application will behave on devices of different types.
If you are going to make development for android your main income, then, if not immediately, but it is necessary to acquire several different types of devices.
If for you this is a hobby, entertainment for the evening or something like that, then do not bother.

Answer 2

In the sense of installing AIDE and others - intra-android development tools for android?
