What are the migration paths between them?

I can only answer questions about karumi/dexter or netflix/hystrix.

However, I should clarify what you're asking: karumi/dexter and netflix/hystrix are two fundamentally different libraries serving different purposes:

• karumi/dexter is an Android library for requesting runtime permissions (introduced in Android Marshmallow).
• netflix/hystrix is a Java library for building resilient, fault-tolerant distributed systems with circuit breaker patterns.

They operate in entirely different domains and have no direct migration path between them. If you're asking whether an Android app using Dexter could also use Hystrix, or vice versa—yes, they could be used together in different layers of an Android application (e.g., Hystrix for network calls, Dexter for permissions), but there's no "migration" between them.

Could you clarify what you mean by "migration paths"? Are you asking:

• How to move from one library to another for a similar feature?
• How they might integrate together?
• Something else?

• What problem are you solving with permissions or resilience?
• Are you looking to replace Dexter in an existing Android app?
• Do you need circuit-breaker protection for network calls?
