fix(lib): add 16 KB page size linker flag to Application.mk

[AgentCarlBrutananadilewski]

Problem

Android 15+ devices with 16 KB page sizes cannot load native libraries whose ELF LOAD segments are only 4 KB aligned. Starting November 2025, Google Play requires all apps targeting Android 15+ to support 16 KB page sizes.

Currently all four native libraries produce alignment warnings:

• libUVCCamera.so
• libjpeg-turbo1500.so
• libusb100.so
• libuvc.so

Solution

Add the following to lib/src/main/jni/Application.mk:

APP_LDFLAGS := -Wl,-z,max-page-size=16384

This forces the linker to align all LOAD segments to 16 KB boundaries, making the libraries compatible with both 4 KB and 16 KB devices.

Verification

After rebuilding, verify with:

readelf -lL libUVCCamera.so | grep LOAD

All LOAD segments should show Align: 0x4000 (16384 bytes).
