Unable to create Keys and Address for Solana network.

[Chandra-Sekhar-Bala]

Hey,
I am a Native Android Developer (Kotlin), Building a Multichain Wallet. I am having issue generating Solana keys and address.
I am able to generate the Mnemonic then Seed from it, also from this I have generated ETH, BTC, TRON private, public keys and public address.
Docs are not clear, even AI couldn't help me to Generate Keys and Address for Solana network from Mnemonic/Seed.

Please any admin, help me.
