Summary
This PR adds 16KB page size support required by Google Play for apps with native code. Google Play Console rejects apps that don't support 16KB ELF page alignment, which is now mandatory for all apps targeting Android 15+.
Problem
Google Play requires all native shared libraries (
.sofiles) to have ELF LOAD segments aligned to 16KB boundaries (p_align >= 0x4000). The existinglibgojni.so(xray-core) andlibtun2socks.sowere compiled with 4KB alignment (0x1000), causing Play Store rejection.Changes

libtun2socks.so(badvpn) is a PIE executable renamed to.so, not a shared library. It was not rebuilt due to NDK 29 compatibility issues with badvpn's CMake config. If Google Play still rejects this file, a fork of badvpn with updated CMake support may be needed.Related Issue
