Native Android SDKs for EVM?
In the meantime, one thing that might be helpful for Android developers is updating the document and/or providing the workaround. If an Android developer follows the documentation, an app won't work. A note along the lines of "web3j for Android is down until further notice", "join the discord for the android workaround", ... might be helpful. There have been some hints (eg 1, 2) about workarounds setup and use, but as far as we can tell, web3j for android is currently broken. It appears that there might be a workaround for most, basic Android web3j functionality, even with v4.8.8-android. We'll try the discord.

Any Smart Contract/Abi to Front-End Code Generator?
Just to add: there is also web3j (https://github.com/web3j/web3j) for the Java people. You can use Maven/Gradle and it generates stubs (classes) which use can use to call the Smart Contracts on any EVM chain. And it is type-safe (as corresponding Java types are used for the Solidity types).

Does a library like web3j only work for the Ethereum network or does it work with any blockchain that uses JSON RPC?

Is there a clean neat way to interface with Ethereum nodes?
There really wasn’t as of about 2 years ago at least. I worked on a Clojure backend that integrated with Ethereum and went with Java interior using https://github.com/web3j/web3j which wasn’t too painful.
