[android] Can not compile projekt [too old dependencies most of times] #54

Hey Setitch, I'm experiencing the same issue did you manage to resolve it? |

Nope |

So I've managed to build the .AAR file now which contains an .so binary for each architecture X86, ARM V7, V8. However, the example application does not boot. The error is logcat is "No implementation found for int com.zerotier.libzt.ZeroTier.init()". The issue with compiling the project seems to be related to ensuring external dependencies are installed on the system. brew install ninja The installed version of java must also be modified in the dist.sh - JDK=jdk1.8.0_251.jdk The android NDK must also be installed available through android studio, I've found that versions So back to the running the example application issue, "No implementation found for int com.zerotier.libzt.ZeroTier.init()". This would suggest that the method is not defined in the library, however I've checked the actual generated binary and it does contain the required Java_com_zerotier_libzt_ZeroTier_init function, with a method body. I've checked the externally visible functions, which lists some of the functions bind,accept,socket,connect but does not contain the init method. Any ideas how I could further debug this? |

After updating Gradle, I'm still getting this error when running |

Hi @Ben-L-E Did you
Hi @Ben-L-E Did you find a solution for the above issue? |

@Chanthujan I ended up switching to Tailscale and Nebula |

@Chanthujan I revisited this project with another attempt. Let me know if it worked: https://drive.google.com/drive/folders/17_D6Cp791E_QObcI9AWshLywps4QWTsm?usp=sharing |

An update on this: Java sources were intentionally removed pending the results of Google V Oracle. We planned on dropping Java support altogether if the case went the wrong way. Now that this is cleared up new (WIP) Java sources have been added. As of this comment they build and pass a basic self-test but still need a lot of refinement, this will take place in the coming weeks. Btw, thanks for your efforts on this @Ben-L-E. I will take a close look at your PR and figure out what parts are still relevant and if anything can be included. |

There were a few I'm attempting to fix in zts_py_recv(): Was allocating a static buffer of 4096, but taking whatever length the user passed in. This change allocates a PyBytes object of the size the user requests. Was converting to a string without giving a size. Which probably led to the UnicodeDecodeError I was seeing below, trying to decode a character beyond the received bytes. Would also lead to problems reading binary data that included embedded NULs. Used the number of bytes received as the size of the returned data. Variable "err" was being used, changed that to "bytes_read" as that's what lwip_recv() returns, with <0 bytes read indicating error. Read data was being returned as a Unicode string, leading to this response when I tried talking to my SSH server: UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa1 in position 42: invalid start byte My ssh banner is 40 bytes long, so I think position 42 was outside the received buffer. Changed it to a PyBytes response as is normal for network data. This code was cribbed from the Python socketmodule This was producing this error, as it was still returning the tuple: SystemError: <built-in function zts_py_recv> returned a result with an error set This indicates that the UnicodeDecodeError had set an exception, but a tuple was being returned instead of NULL. In the case of a lwip_recv() error, the error response was not being sent back to the wrapper code. Instead, a "return NULL;" was done. I changed this case to return the tuple (err, None) to the wrapper. NOTE: this code built using "./build.sh host-python release", but there was some sort of build problem I didn't understand which produced a _libzt.so that I couldn't import, due to: ImportError: dynamic module does not define module export function (PyInit__libzt) So I don't have a way to test these changes. * Better random number generation in selftest * Bugfix: Check argument types and encodings in zts_py_send() * Move Python license into ext/THIRDPARTY.txt * Update PyPI package version to 1.3.4b1 * Update PyPI package build workflow to build Swig wrapper automatically * Assorted Python changes based on a code review. Many changes were based on conventions in the Python socketmodule. Changed many of the docstrings to match the Python socket library conventions and enhancing them. I can either remove the prototype part or add it to other docstrings in the library, depending on feedback I get. Changed setblocking to use the flag argument instead of always just setting NONBLOCK. Added enable/disable threading around more lwip calls. Implementing optional backlog on listen(). Removing a few seemingly unneeded Py_INCREF(Py_None) calls. Moved getblocking function based on alpha sorting of names. * Fixing some bugs in socket blocking. There were some bugs in my blocking code that are fixed in this. I had the setblocking() flag reversed, and wasn't passing the flag along to the underlying code properly. * Remove out-of-place includes for signal handler functions * Minor Windows build fixes * Add NuGet package workflow * Replace manual csc.exe invokation with dotnet project (for NuGet build) * Python send() with binary data zts_py_send() was using strlen() to determine the length of the send(). This works fine with strings, but fails with binary data. To fix this, I have removed the string encoding code, and converted to using the Buffer protocol as is done in the Python socketmodule send() implementation. This does mean that this send() implementation only takes byte-like objects. The workaround for this could be at the python level rather than the C++ level. NOTE: This implementation has a bug in the exception handling if a non-bytes-like object is passed. You get an exception, but the exception is not accurate, it reports the TypeError, but the actual raised exception is due to there being a return value when the error indicator is set. I spent a few hours trying to fix this but was unable to. I'm afraid I just couldn't figure it out. My SSH proxy was misbehaving because the second block of data going from the client to the server had a NUL byte as the first byte to send, so the send was returning 0 bytes sent, but that was due to send() being told to send 0 bytes. With this, my SSH proxy is now working, including able to run an rsync of my boot initrd over SSH over ZeroTier entirely in userspace. * Update C API: Add functions that simplify wrapper generation * Fixed memleak, optimize and refactor code * Add IPv6 to C# ZeroTier.Sockets, Add C# selftest, Misc C API improvements * Add .clang-format file * Applied styling rules from .clang-format * Add code style enforcement to github workflow * Remove C++ examples (To be replaced with C examples) * Update .clang-format code style * Update .clang-format code style * Update workflows * Adjust test targets and code style enforcement in build script * Expand C API and simplify NodeService * Code style fixes * Add zts_core_query_ and world sub-APIs.

I tried compiling the library to android, C/CPP without a problem, but android part - failes all of times. I already used one week to try to compile the aar file, and it is still failing.
Issues from start
*. Updating gradle works
finding all of this, downloading proper sdk and ndk (trying almost every combination) still fails.
Would it be possible to get library we will be able to compile properly on modern java and systems? Please
