while I sh compile.sh, jni.h file not found
and I run the command in terminal
have the same error, can't output libjni.so
and I want to support arm64-v8a and armeabi-v7a in android, how can i do?
Tks!
1.Complete refactoring to type/interface structure
2.Synchronize the latest json-rpc
3.Authoring of network items with latest network
Main Java sources https://github.com/polkadot-java/api/tree/master/packages/src
were not updated for 2 years, and there were never public release to maven Central #13
This looks like dead project.
I tried to build that with ndk toolchains an when i tried to use that got this exception
java.lang.UnsatisfiedLinkError: dlopen failed: cannot locate symbol "_Unwind_Backtrace" referenced by "/data/app/jp.co.soramitsu.sora.develop-QgQ2h40xY4_vNE-yhvKgpg==/lib/arm64/libjni.so"...Synchronize the latest type modules, including Primitive types, Substrate types, Codec types, RPC types, Derived types.
