Can we run android operating system inside a kubernetes pod?

What you're talking about sounds like a stateful workload for which you should use StatefulSet rather than a Deployment. As you can read in the docs, it guarantees uniqueness of each pod:

StatefulSet is the workload API object used to manage statefulapplications.

Manages the deployment and scaling of a set ofPods, andprovides guarantees about the ordering and uniqueness of these Pods.

Like aDeployment,a StatefulSet manages Pods that are based on an identical containerspec. Unlike a Deployment, a StatefulSet maintains a sticky identityfor each of their Pods. These pods are created from the same spec, butare not interchangeable: each has a persistent identifier that itmaintains across any rescheduling.

If you want to use storage volumes to provide persistence for yourworkload, you can use a StatefulSet as part of the solution. Althoughindividual Pods in a StatefulSet are susceptible to failure, thepersistent Pod identifiers make it easier to match existing volumes tothe new Pods that replace any that have failed.

If you're running it on some cloud environment, you can expose it via LoadBalancer service type so you can access it remotely.
