获取是否是eng load or 非eng loa办法

1.在Android.mk中定义一个ENGload时的flag

Android.mk
....
ifeq ($(TARGET_BUILD_VARIANT),eng)//user,userdebug.
   LOCAL_CFLAGS += -D__ENG_LOAD
endif

在code中：

#if defined (__ENG_LOAD)

//do sth.

#endif

2.方法2，动态获取

#include <cutils/properties.h>

static bool IsEngLoad(){
    static int fistCheck =-1;
    if(fistCheck !=-1){
        return firstCheck;
    }
    char propbuf[PROPERTY_VALUE_MAX];
    property_get("ro.build.type",propbuf,"user");
    if (strcmp(propbuf,"eng" == 0)){//is eng load
        firstCheck = 1;
        return true;
    }
    firstcheck = 0;
    return false;
}

 3."user".equals(Build.TYPE)

"userdebug".equals(Build.TYPE)
