How to get all the mount point information for android device?

Question

How do I get all the mount point information for an Android device programmatically?

Answer 1

Not exactly part of the android apis, but the underlying linux will tell you about the ones that are in use if you read /proc/mounts

As a clarification, in later Android versions Linux's ability to have unique mounts for each process ancestry is leveraged, so the mounts seen by an application process can (and typically will) be different than those seen by something launched from ADB, or a core system process.
