AndroidNDK&JNI1---NDK&JNI静态

1、安装和配置（linux）

  • Download from Android Developer–android-ndk-r10e-linux-x86_64.bin
  • vim ~/.bashrc
  • source ~/.bashrc

2、JNI(静态使用)

  • 加载以后使用 ndk-build 脚本生成的so库
  •      依照JNI，生成.h文件。
  • 创建.c文件
  • #include <string.h>
#include <jni.h>

JNIEXPORT jstring JNICALL Java_com_example_hellojni_HelloJni_stringFromJNI
  (JNIEnv * env, jclass class)
{
    return (*env)->NewStringUTF(env,"Hello my love");
}
    View Code

3、创建项目makefile和jni makefile

  •  1 LOCAL_PATH:= $(call my-dir)
 2 include $(CLEAR_VARS)
 3 
 4 LOCAL_MODULE_TAGS := samples
 5 
 6 LOCAL_SRC_FILES := $(call all-subdir-java-files)
 7 
 8 LOCAL_PACKAGE_NAME := HelloJni
 9 
10 LOCAL_JNI_SHARED_LIBRARIES := libhellostatic
11 
12 LOCAL_PROGUARD_ENABLED := disabled
13 
14 LOCAL_SDK_VERSION := current
15 
16 include $(BUILD_PACKAGE)
17 
18 # ============================================================
19 
20 # Also build all of the sub-targets under this one: the shared library.
21 include $(call all-makefiles-under,$(LOCAL_PATH))
    View Code

     

  • 1 LOCAL_PATH := $(call my-dir)
2 include $(CLEAR_VARS)
3 
4 LOCAL_MODULE := libhellostatic
5 LOCAL_SRC_FILES := myjni.c
6 
7 include $(BUILD_SHARED_LIBRARY)
    View Code

     

4、使用ndk-build 生成 so库(详情见makefile)
