项目中加入 org.apache.http.legacy.jar 可以解决。
原始文件在sdk中可以找到，路劲
android-sdk-windows\platforms\android-xx\optional\
类似引用
import org.apache.http.Header;
import org.apache.http.HttpResponse;
import org.apache.http.client.CookieStore;
import org.apache.http.cookie.Cookie;
import org.apache.http.protocol.HTTP;
import org.apache.http.util.EntityUtils;
android.mk 使用方式
LOCAL_STATIC_JAVA_LIBRARIES :=
xUtils
apache-http
include $(BUILD_PACKAGE)
include $(CLEAR_VARS)
LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := xUtils:libs/xUtils-2.6.13.jar
apache-http:libs/org.apache.http.legacy.jar
include $(BUILD_MULTI_PREBUILT)
