在Android中使用第三方的库

修改Android.mk

添加一个 libaec.so 和 Speex的支持

include $(CLEAR_VARS)
LOCAL_MODULE := libaec
LOCAL_MODULE_SUFFIX := .so
LOCAL_MODULE_CLASS := SHARED_LIBRARIES
LOCAL_SRC_FILES := libs/libaec.so
include $(BUILD_PREBUILT)
LOCAL_C_INCLUDES := \
$(TOPDIR)frameworks/av/services/audiopolicy \
$(TOPDIR)external/sonic \
$(call include-path-for, audio-effects) \
$(call include-path-for, audio-utils) \
$(call include-path-for, speex)
LOCAL_SHARED_LIBRARIES := \
......
libaec \
libspeexresampler

打log

//----------- android log start -----------
#if defined(__ANDROID__)
#include <android/log.h>

#define LOG_TAG "System.out.c"
#define LOGD(...) __android_log_print(ANDROID_LOG_DEBUG, LOG_TAG, __VA_ARGS__)
#define LOGI(...) __android_log_print(ANDROID_LOG_INFO, LOG_TAG, __VA_ARGS__)
#endif  // defined(__ANDROID__)
//----------- android log end -----------

使用

int n =100;
LOGI("hello %d", n);
