3.
Tell the NDK build system how to treat the
.cpp
ile. Create the
jni/Android.mk
ile. The
Android.mk
ile is used by the Android NDK build system to ind out how to
treat the source code of your project:
TARGET_PLATFORM := android-7
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_ARM_MODE := arm
LOCAL_MODULE := App2
LOCAL_SRC_FILES += Wrappers.cpp
LOCAL_ARM_MODE := arm
COMMON_CFLAGS := -Werror -DANDROID -DDISABLE_IMPORTGL \
-isystem $(SYSROOT)/usr/include/
ifeq ($(TARGET_ARCH),x86)
LOCAL_CFLAGS := $(COMMON_CFLAGS)
else
LOCAL_CFLAGS := -mfpu=vfp -mfloat-abi=softfp \
-fno-short-enums $(COMMON_CFLAGS)
endif
LOCAL_LDLIBS := -llog -lGLESv2 -Wl,-s
LOCAL_CPPFLAGS += -std=gnu++0x
include $(BUILD_SHARED_LIBRARY)
Note the
ifeq ($(TARGET_ARCH),x86)
section. Here we specify architecture-
speciic compiler lags for loating point support on ARMv7. This will give you
hardware loating-point support on the ARM architecture and a warnings-free
log on the x86 Android target architecture..
4.
Paste the following code into the
jni/Application.mk
ile:
APP_OPTIM := release
APP_PLATFORM := android-7
APP_STL := gnustl_static
APP_CPPFLAGS += -frtti
APP_CPPFLAGS += -fexceptions
APP_CPPFLAGS += -DANDROID
APP_ABI := armeabi-v7a
APP_MODULES := App2
NDK_TOOLCHAIN_VERSION := clang
