Nostr

#android #java #dev #asknostr

Still workin' on my project. I've been running into a series of issues trying to get nostr:npub1llfht66qadyxv44q9rkmequztav07r2ufgd6ytl8w3wjs3ffa5yqy398ja's nostr-java library to work with my app.

If anyone wants to help me, I'd really appreciate it. Currently, I'm trying to figure out how to set the "java.version" system property (https://howtodoinjava.com/java/basics/java-system-properties/#1-1-runtime-environment-properties), because it's required to be set for the jetty library to work properly: https://github.com/jetty/jetty.project/blob/ae6f98ed47ada09dd393102cea0bdf29bc7eb2ea/jetty-core/jetty-alpn/jetty-alpn-java-server/src/main/java/org/eclipse/jetty/alpn/java/server/JDK9ServerALPNProcessor.java#L37.

So far, nothing I've found online for setting this system property has resulted in any different behavior (the "java.version" property is always "0").

E.g., I tried this: https://docs.gradle.org/current/userguide/build_environment.html#sec:gradle_system_properties

If I try to set this value in the runtime code, I get this error message in logcat:

`System : Ignoring attempt to set property "java.version" to value "9.0.0".`

To keep whoever's intetested posted, my nostr based waze-clone for Android is currently depending on the nostr-java library to be updated to support android and correct its implementation of some nostr features.

"enabler" means "of evil people and deeds" not "empower" to "do good and and important works"

it may have a different context in your language, in english enabler means someone who comforts and assists evil

kuiperbelt 1y ago

Can you give any example of how an individual can enable an evil person or evil deed, and what how that enabling practically works?

Do some nostr clients post "sensitive content warnings" when users block another user based on a particular post?

I think cryptic error messages in libraries probably add up to tremendous productivity loss.

The issue occurs while I'm fetching the relay Metadata. I need the information because I want to know which nips the relay supports.

I use jetty's httpclient for establishing the remote http connection, and your code does not seem to like it.

Looking at the stack trace, I see it cannot link several native libraries, likely because you're on Android.

I don't think the library can be used on android for the above reasons, and to make it work, I would have to ditch jetty, and use the jdk's native libraries for http and websocket connections. This would be a non trivial change that would take time to develop, but I'll look more into it.

kuiperbelt 1y ago

I'm interested in transitioning to jdk's native libraries and willing to work on it.

I think conscrypt can load one of these libraries from the "resource" folder: https://github.com/google/conscrypt/blob/59de3194ca10ac29521b837928e467029c1d7479/openjdk/src/main/java/org/conscrypt/NativeLibraryLoader.java#L165

But adding the library to resource/META_INF/native/ didn't change the resulting behavior.

I added the conscrypt client to my app's dependencies, and now this is the stack trace:
