Android NDK 中使用STL

ndk版本:Android-ndk-r8d,基于ndk自带samples中的test-libstdc++工程进行修改。

1. 例子工程目录结构:
test-libstdc++ / jni / Android.mk
test-libstdc++ / jni / Application.mk
test-libstdc++ / jni / test-libstdc++.cpp

2. Android.mk文件:

# A simple test for the minimal standard C++ library
#
LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE := test-libstl
LOCAL_SRC_FILES := test-libstl.cpp
LOCAL_LDLIBS    := -llog

include $(BUILD_EXECUTABLE)

include $(CLEAR_VARS)
LOCAL_EXECUTABLE := test-libstl

3. Application.mk内容:

APP_STL := stlport_static

4. test-libstdc++.cpp内容:

#include <iostream>
#include <string>
#include <vector>
using namespace std;

int main() {
 vector<string> contents;
 for (int i=0; i<5; i++)
 {
  contents.push_back(string("vector"));
 }
 
 for (int i=0; i<5; i++)
 {
  cout << contents[i] << endl;
 }
 
 cout << "hello, world\n";
 return 0;
}

5. 最后在test-libstdc++\libs\armeabi目录下面生成test-libstl 可执行程序。原理类似tcpdump工具使用,通过adb推到手机上,在shell模式下运行改可执行程序:

D:\android-sdk-windows\platform-tools>adb push test-libstl /data/local/
1341 KB/s (251396 bytes in 0.182s)

D:\android-sdk-windows\platform-tools>adb shell chmod 755 /data/local/test-libstl

D:\android-sdk-windows\platform-tools>adb shell /data/local/test-libstl
vector
vector
vector
vector
vector
hello, world
