vuforia 示例项目中的应用程序崩溃

Question

我正在尝试运行 vuforia Imagetarget 示例项目，其中显示本机函数错误，“无法解析相应的 JNI 函数 Java_com_vuforia_samples_ImageTargets_ImageTargets_setActivityPortraitMode”。

还会出现运行时错误和应用崩溃。下面是错误日志，

Android.mk 文件：

# An Android.mk file must begin with the definition of the LOCAL_PATH
# variable. It is used to locate source files in the development tree. Here
# the macro function 'my-dir' (provided by the build system) is used to return
# the path of the current directory.

LOCAL_PATH := $(call my-dir)

# The following section is used for copying the libVuforia.so prebuilt library
# into the appropriate folder (libs/armeabi and libs/armeabi-v7a respectively)
# and setting the include path for library-specific header files.

include $(CLEAR_VARS)
LOCAL_MODULE := Vuforia-prebuilt
LOCAL_SRC_FILES = ../../../../../../build/lib/$(TARGET_ARCH_ABI)/libVuforia.so
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/../../../../../../build/include
include $(PREBUILT_SHARED_LIBRARY)

#-----------------------------------------------------------------------------

# The CLEAR_VARS variable is provided by the build system and points to a
# special GNU Makefile that will clear many LOCAL_XXX variables for you
# (e.g. LOCAL_MODULE, LOCAL_SRC_FILES, LOCAL_STATIC_LIBRARIES, etc...),
# with the exception of LOCAL_PATH. This is needed because all build
# control files are parsed in a single GNU Make execution context where
# all variables are global.

include $(CLEAR_VARS)

# The LOCAL_MODULE variable must be defined to identify each module you
# describe in your Android.mk. The name must be *unique* and not contain
# any spaces. Note that the build system will automatically add proper
# prefix and suffix to the corresponding generated file. In other words,
# a shared library module named 'foo' will generate 'libfoo.so'.

LOCAL_MODULE := ImageTargetsNative

# Set OpenGL ES version-specific settings.
OPENGLES_LIB  := -lGLESv2
OPENGLES_DEF  := -DUSE_OPENGL_ES_2_0

# An optional set of compiler flags that will be passed when building
# C and C++ source files.
#
# The flag "-Wno-write-strings" removes warnings about deprecated conversion
#   from string constant to 'char*'.
# The flag "-Wno-psabi" removes warning about "mangling of 'va_list' has
#   changed in GCC 4.4" when compiled with certain Android NDK versions.

LOCAL_CFLAGS := -Wno-write-strings -Wno-psabi $(OPENGLES_DEF) -std=c++11

# The list of additional linker flags to be used when building your
# module. Use the "-l" prefix in front of the name of libraries you want to
# link to your module.

LOCAL_LDLIBS := \
-llog $(OPENGLES_LIB)

# The list of shared libraries this module depends on at runtime.
# This information is used at link time to embed the corresponding information
# in the generated file. Here we reference the prebuilt library defined earlier
# in this makefile.

LOCAL_SHARED_LIBRARIES := Vuforia-prebuilt

# The LOCAL_SRC_FILES variables must contain a list of C/C++ source files
# that will be built and assembled into a module. Note that you should not
# list header file and included files here because the build system will
# compute dependencies automatically for you, just list the source files
# that will be passed directly to a compiler.

LOCAL_SRC_FILES := ImageTargets.cpp SampleAppRenderer.cpp SampleUtils.cpp 
Texture.cpp

# By default, ARM target binaries will be generated in 'thumb' mode, where
# each instruction is 16-bit wide. You can set this variable to 'arm' to
# set the generation of the module's object files to 'arm' (32-bit
# instructions) mode, resulting in potentially faster yet somewhat larger
# binary code.

LOCAL_ARM_MODE := arm

# BUILD_SHARED_LIBRARY is a variable provided by the build system that
# points to a GNU Makefile script being in charge of collecting all the
# information you have defined in LOCAL_XXX variables since the latest
# 'include $(CLEAR_VARS)' statement, determining what and how to build.
# Replace it with the statement BUILD_STATIC_LIBRARY to generate a static
# library instead.

include $(BUILD_SHARED_LIBRARY)

Application.mk 文件：

# Build both ARMv5TE and ARMv7-A machine code.

APP_ABI := armeabi-v7a

# Set target Android API level to the application's minimum SDK version.

APP_PLATFORM := android-14

# This optional variable can be defined to either 'release' or
# 'debug'. This is used to alter the optimization level when
# building your application's modules.
#
# A 'release' mode is the default, and will generate highly
# optimized binaries. The 'debug' mode will generate un-optimized
# binaries which are much easier to debug.
#
# Note that it is possible to debug both 'release' and 'debug'
# binaries, but the 'release' builds tend to provide less information
# during debugging sessions: some variables are optimized out and
# can't be inspected, code re-ordering can make stepping through
# the code difficult, stack traces may not be reliable, etc... 

# APP_OPTIM := release OR debug

libImageTargetsNative.so 和 libVuforia.so 的路径是 app/src/main/jniLibs。

所有mk文件、cpp文件和头文件都在jni文件夹下。

请告诉我是我遗漏了什么还是我的代码中有任何错误。 提前致谢。

尝试使用旧版本的 Unity。每次 Unity 发布更新时，我的 vuforia 项目都会停止工作，所以我正在使用 Unity 5.2 并且不再更新
