初试jni

项目需要调用第三方so库

关键代码 android.mk

 LOCAL_PATH := $(call my-dir)  
include $(CLEAR_VARS)
LOCAL_MODULE := libAdCaster
LOCAL_SRC_FILES := libAdCaster.so
include $(PREBUILT_SHARED_LIBRARY)


include $(CLEAR_VARS)  
LOCAL_MODULE    := MyLib
LOCAL_C_INCLUDES := $(LOCAL_PATH)/include
LOCAL_SHARED_LIBRARIES  := libAdCaster
LOCAL_SRC_FILES := AdCaster.cpp
LOCAL_LDLIBS += -llog -lGLESv2 
include $(BUILD_SHARED_LIBRARY)

写native时，要注意库的加载顺序

static {
System.loadLibrary("AdCaster");
System.loadLibrary("MyLib");
}
