# Android makefile to be used with ndk-build.

# Run ndk-build with the following arguments:
#	APP_BUILD_SCRIPT=platform/java/Android.mk (this file)
#	APP_PROJECT_DIR=build/android (where you want the output)
#	APP_PLATFORM=android-16
#	APP_OPTIM=release (or debug)
#	APP_ABI=all (or armeabi, armeabi-v7a, arm64-v8a, x86, x86_64, mips, mips64)
#
# The top-level Makefile will invoke ndk-build with appropriate arguments
# if you run 'make android'.
#
# Use the MUPDF_EXTRA_CFLAGS, MUPDF_EXTRA_CPPFLAGS, MUPDF_EXTRA_LDFLAGS,
# and MUPDF_EXTRA_LDLIBS variables to add more compiler flags.
#
# LOCAL_C_INCLUDES paths are relative to the NDK root directory.
# LOCAL_SRC_FILES paths are relative to LOCAL_PATH.
#
# We make sure to use absolute paths everywhere, so this makefile works
# regardless of where it is called from.
