Android ndk ndk生成可执行文件未被识别为可执行文件

我只是尝试为一个简单的hello程序进行ndk构建

Android.mk文件：

LOCAL_PATH:= $(call my-dir) # Get the local path of the project.
include $(CLEAR_VARS) # Clear all the variables with a prefix "LOCAL_"

LOCAL_SRC_FILES:=hello.cpp # Indicate the source code.
LOCAL_MODULE:= hello # The name of the binary.
LOCAL_ARM_MODE := arm
include $(BUILD_EXECUTABLE) # Tell ndk-build that we want to build a native executable.

Application.mk文件：

APP_ABI := armeabi-v7a # Define the target architecture to be ARM.
APP_STL := gnustl_static
#APP_STL := gnustl_static
APP_CPPFLAGS := -frtti -fexceptions    # This is the place you enable exception.
APP_PLATFORM = android-19

源文件（hello.cpp）：

那么，我的设置有什么问题？就是不知道为什么。

提前感谢。

似乎是与emulator相关的问题。把它推到Android设备上，它就可以工作了。

模拟器可以配置为只运行一种CPU ABI。您的模拟器可能已设置为x86。检查以确保正在Application.mk中构建的ABI与在emulator中配置的ABI匹配。例如，如果您的模拟器正在运行x86：

确保Application.mk文件也设置为相同的值：

APP_ABI := x86    

[armeabi-v7a] Compile++ arm  : hello <= hello.cpp
[armeabi-v7a] Executable     : hello
[armeabi-v7a] Install        : hello => libs/armeabi-v7a/hello
