Add -DANDROID_SUPPORT_FLEXIBLE_PAGE_SIZES=ON to CMake arguments so that libangle_android_graphic_jni.so is compiled with 16KB ELF segment alignment. NDK 27 and older default to 0x1000 (4KB) PT_LOAD alignment, which is incompatible with 16KB-page kernels on Android 15+. Google Play requires all apps to support 16KB pages by May 31 2026. The flag instructs the NDK linker to emit 0x4000 (16KB) PT_LOAD alignment, which is backward-compatible with 4KB-page devices. Fixes Knightro63#49

Problem
Closes #49
libangle_android_graphic_jni.socompiled with NDK 27 (or older) defaults to0x1000(4KB) PT_LOAD ELF segment alignment. This is incompatible with 16KB-page kernels on Android 15+ devices. Google Play now requires all apps to support 16KB pages by May 31, 2026, or distribution will be blocked.Root Cause
NDK 27 and older set
max-page-size=4096as the linker default for aarch64. NDK 28 changed this default to16384, but projects still on NDK 27 are affected.Fix
Add
-DANDROID_SUPPORT_FLEXIBLE_PAGE_SIZES=ONto the CMake arguments inbuild.gradle. This instructs the NDK linker to emit0x4000(16KB) PT_LOAD alignment — fully backward-compatible with 4KB-page devices.Verification
Compiled
