윈도우폰 8.1 개발 시작

윈도우폰 8.1 개발을 시작하였다.
먼저 Visual Studio 2013 Update 4를 설치해야 한다.
그리고 에뮬레이터를 실행하려면 Hyper-V를 CMOS를 셋팅해야한다.
전부다 셋팅 했더니 에뮬레이터가 잘돌아간다.
안드로이드 에뮬레이터보다 훨씬 낫고 거의 Xcode의 아이폰 시뮬레이터급이다.

Android NDK jstring char*로 변환

JNIEXPORT void JNICALL Java_ClassName_MethodName(JNIEnv *env, jobject obj, jstring javaString)
{
    const char *nativeString = (*env)->GetStringUTFChars(env, javaString, 0);
    // use your string
    (*env)->ReleaseStringUTFChars(env, javaString, nativeString);
}

PHP json_decode후 데이터 접근하기

다음과 같이 데이터를 json_decode한 후에 그 내용을 접근하려면 다음과 같이 한다.

$json_result = json_decode($rawPost);
$serviceId = $json_result->{'serviceId'};

문제는 배열 접근하듯이 []가 아니라 {}라는 점이다. 예전 버전에는 그냥 $json_result->serviceId 이렇게 하면 되었었는데 지금은 그게 안되는 것 같다.

PHP 에러메세지 표시하기

요즘 PHP버전은 에러메세지가 표시하지 않게 되어 있다. 그래서 다음과 같이 PHP문 처음에명시하면 모든 에러메세지를 받을 수 있다.

error_reporting(E_ALL);
ini_set("display_errors", 1);

PHP JSON POST data stream 받기

http://stackoverflow.com/questions/4369759/how-to-recieve-post-data-sent-using-application-octet-stream-in-php

같이 일하는 회사에서 JSON 포맷을 data stream 형태로 POST 방식으로 보내준다고 하였다. 그런데 PHP를 한지 하도 오래되어서 몰랐는데 이런 것이 있었다. 정식 명칭은 application/octet-stream이다.

$rawPost = file_get_contents('php://input');

Windows 실행파일 패스 알아보기(where)

유닉스에서는 어떤 명령어(프로그램)의 바이너리 위치를 알기위해서는 whereis를 사용했다. 윈도우 cmd에서는 where를 사용한다.(is가 빠짐) 아래에서 msbuild.exe의 패스 위치를 알아보자. 현재 패스 우선순위상으로는 MSBuild 2.0이 4.0보다 높은 순위에 있다. 이러면 msbuild를 입력하면 4.0대신에 2.0이 호출된다.

예제)where msbuild
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\MSBuild.exe C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe

Android 5.0 호환성 문제 - sprintf 직접 구현

예전에 안드로이드 5.0에서 sprintf를 NDK에서 사용했더니 로케일이 달라서 씹히던 문제가 있었다. 그래서 로케일을 상관하지 않는 ANSI용 sprintf를 직접 구현한 소스를 조립해서 NDK에서 기존 sprintf를 대체하니 문제가 말끔히 해결되었다. 다음은 sprintf를 직접 구현한 소스이다. 물론 vsprintf도 직접 구현하였다. 구분 하기 위해서 새로 구현한 sprintf는 대문자로 SPRINTF2라고 명명하였다.
