I have written an application in Ada and I want to run it on Android (ARM devices). I have compiled a native standalone library for ARM (arm64-v8a) on a Raspberry Pi, containing the proper JNI. However, when I launch the application in Android it fails while loading the library (right on the System.loadLibrary call). Is there something theoretically wrong in proceeding this way, or should it work?

Before doing this experiment on android, I successfully loaded an Ada test library on Java using a x64 PC, so I don't think the problem is in the interface itself. I would have expected the library to be loaded without issues.

For the full code to see what I am trying to do, please, have a look at GuillermoHazebrouck/gnav on GitHub.

I am looking at using Blockfrost.io API in order to read cardano transactions, I am looking to get the bare minimum which is:

• Address from
• Address to
• Assets transfered (type + amount)
• Fees

So far I can not find how to retrieve a transaction addresses from and to while using:

https://docs.blockfrost.io/#tag/Cardano-Transactions/paths/~1txs~1%7Bhash%7D/get

Am I missing something?
