Reference Error On Android Using .so File Of GRAPES

[Awaaz-Shinwari]

I compiled the GRAPES library through NDK cross tools and generated the .so file of this. but when i port that .so file in the android studio and run the project then i get the following error.
java.lang.UnstaisfiedLinkError: dlopen failed:cannot locate symbol "send_to_peer" referenced by "libgrapes.so"

Kindly help me regarding this.

Hi Awaaz,
the GRAPES library defines the interface of what we call the "net_helper" layer (include/net_helper.h), though it does not provide an implementation (which is application dependent).
That layer is responsible of dispatching and retrieving P2P messages. You can find two possible implementation in its sister project, in particular net_helper-udp is a single file, straightforward implementation.
So if you want to have GRAPES up and running, just compile net_helper-udp.c and add it to your project.

Dear Baldesi, I'm deeply thankful for your help. I'm going to try the solution that you proposed for my project and will get back to you soon. Thanks again. Regards Awaaz Shinwari

Dear Baldesi,
I tried your solution but my project needs the whole library "GRAPES" to be compiled and port to android studio so that my rest of the project starts working. So kindly help me in compiling and porting the GRAPES library in Android Studio.
I cross compiled the library through NDK standalone tool-chain and generated the .so file "libgrapes.so" but when i run the android project, having libgrapes.so in it, then it gives a run time error given below:

Java.lang.UnstaisfiedLinkError:dlopen failed:library“../../../../src/main/jniLibs/x86/libgrapes.so” not found

kindly help me in this regard
