HIDL第一个Hello World 搞代码

# source build/envsetup.sh
# lunch
# make hidl-gen -j4
一、server端
1.创建INaruto.hal文件
# cd hardware
# mkdir -p ~/android/hardware/interfaces/naruto/1.0/default 
# cd hardware/interfaces/naruto/1.0
# emacs INaruto.hal
package android.hardware.naruto@1.0;
 
interface INaruto {
    helloWorld(string name) generates (string result);
};
 
2.使用hidl-gen工具编译INaruto.hal自动生成.mk,.bp,.cpp文件
# cd ~/android
# PACKAGE=android.hardware.naruto@1.0
# LOC=hardware/interfaces/naruto/1.0/default/
# make hidl-gen -j16
# hidl-gen -o $LOC -Lc++-impl -randroid.hardware:hardware/interfaces -randroid.hidl:system/libhidl/transport $PACKAGE
# hidl-gen -o $LOC -Landroidbp-impl -randroid.hardware:hardware/interfaces -randroid.hidl:system/libhidl/transport $PACKAGE
在default下生成Android.bp，Naruto.cpp，Naruto.h文件
# ./hardware/interfaces/update-makefiles.sh
在1.0目录下生成Android.bp，Android.mk文件
 
# touch hardware/interfaces/naruto/1.0/default/android.hardware.naruto@1.0-service.rc
# touch hardware/interfaces/naruto/1.0/default/service.cpp
 
 
3.修改源码，然后编译自动生成文件
# mmm hardware/interfaces/naruto/1.0/default/
 
4.启动server端进程
# emacs hardware/interfaces/naruto/1.0/default/android.hardware.naruto@1.0-service.rc
service naruto_hal_service /vendor/bin/hw/android.hardware.naruto@1.0-service
    class hal
    user system
    group system
 
5.server端进程源码
# emacs hardware/interfaces/naruto/1.0/default/service.cpp
#define LOG_TAG "android.hardware.naruto@1.0-service"
#include <android/hardware/naruto/1.0/INaruto.h>
#include <hidl/LegacySupport.h>
 
using android::hardware::naruto::V1_0::INaruto;
using android::hardware::defaultPassthroughServiceImplementation;
 
int main() {
    return defaultPassthroughServiceImplementation<INaruto>();
}
 
6.编译server端代码
# mmm hardware/interfaces/naruto/1.0/default
 
7.编译vendor.img,刷机
# make vendorimage -j16
 
二、client端
 
1.测试代码: naruto_test
# emacs test.cpp
#include <android/hardware/naruto/1.0/INaruto.h>
#include <hidl/Status.h>
#include <hidl/LegacySupport.h>
#include <utils/misc.h>
#include <hidl/HidlSupport.h>
#include <stdio.h>
 
using android::hardware::naruto::V1_0::INaruto;
using android::sp;
using android::hardware::hidl_string;
 
int main()
{
    int ret;
 
    android::sp<INaruto> service = INaruto::getService();
    if(service == nullptr) {
        printf("Failed to get service\n");
        return -1;
    }
 
    service->helloWorld("JayZhang", [&](hidl_string result) {
                printf("%s\n", result.c_str());
        });
 
    return 0;
}
 
2.Android.mk
LOCAL_PATH := $(call my-dir)
 
include $(CLEAR_VARS)
LOCAL_PROPRIETARY_MODULE := true
LOCAL_MODULE := naruto_test
LOCAL_SRC_FILES := \
    client.cpp \
 
LOCAL_SHARED_LIBRARIES := \
   liblog \
   libhidlbase \
   libutils \
   android.hardware.naruto@1.0 \
 
include $(BUILD_EXECUTABLE)
 
3.在manifest文件里添加vendor接口的定义，不然在client端是没法拿到service的，在相应的manifest.xml里面加入
# emacs manifest.xml 
…
…
<hal format="hidl">
    <name>android.hardware.naruto</name>
    <transport>hwbinder</transport>
    <version>1.0</version>
    <interface>
        <name>INaruto</name>
        <instance>default</instance>
    </interface>
</hal>
 
# adb push manifest.xml /vendor
 
 
三、烧写vendor.img测试
# adb shell
# /vendor/bin/hw/android.hardware.naruto@1.0-service
 
# ./naruto_test

# source build/envsetup.sh

# make hidl-gen -j4

一、server端

1.创建INaruto.hal文件

# cd hardware

# mkdir -p ~/android/hardware/interfaces/naruto/1.0/default

# cd hardware/interfaces/naruto/1.0

# emacs INaruto.hal

package android.hardware.naruto@1.0;

interface INaruto {

helloWorld(string name) generates (string result);

};

2.使用hidl-gen工具编译INaruto.hal自动生成.mk,.bp,.cpp文件

# cd ~/android

# [email protected]

# LOC=hardware/interfaces/naruto/1.0/default/

# make hidl-gen -j16

# hidl-gen -o $LOC -Lc++-impl -randroid.hardware:hardware/interfaces -randroid.hidl:system/libhidl/transport $PACKAGE

# hidl-gen -o $LOC -Landroidbp-impl -randroid.hardware:hardware/interfaces -randroid.hidl:system/libhidl/transport $PACKAGE

在default下生成Android.bp，Naruto.cpp，Naruto.h文件

# ./hardware/interfaces/update-makefiles.sh

在1.0目录下生成Android.bp，Android.mk文件

# touch [email protected]0-service.rc

# touch hardware/interfaces/naruto/1.0/default/service.cpp

3.修改源码，然后编译自动生成文件

# mmm hardware/interfaces/naruto/1.0/default/

4.启动server端进程

# emacs [email protected]0-service.rc

service naruto_hal_service /vendor/bin/hw/android.hardware.naruto@1.0-service

class hal

user system

group system

5.server端进程源码

# emacs hardware/interfaces/naruto/1.0/default/service.cpp

#define LOG_TAG "[email protected]"

#include <android/hardware/naruto/1.0/INaruto.h>

#include <hidl/LegacySupport.h>

using android::hardware::naruto::V1_0::INaruto;

using android::hardware::defaultPassthroughServiceImplementation;

int main() {

return defaultPassthroughServiceImplementation<INaruto>();

}

6.编译server端代码

# mmm hardware/interfaces/naruto/1.0/default

7.编译vendor.img,刷机

# make vendorimage -j16

二、client端

1.测试代码: naruto_test

# emacs test.cpp

#include <android/hardware/naruto/1.0/INaruto.h>

#include <hidl/Status.h>

#include <hidl/LegacySupport.h>

#include <utils/misc.h>

#include <hidl/HidlSupport.h>

#include <stdio.h>

using android::hardware::naruto::V1_0::INaruto;

using android::sp;

using android::hardware::hidl_string;

int main()

{

int ret;

android::sp<INaruto> service = INaruto::getService();

if(service == nullptr) {

printf("Failed to get service\n");

return -1;

}

service->helloWorld("JayZhang", [&](hidl_string result) {

printf("%s\n", result.c_str());

});

return 0;

}

2.Android.mk

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_PROPRIETARY_MODULE := true

LOCAL_MODULE := naruto_test

LOCAL_SRC_FILES := \

client.cpp \

LOCAL_SHARED_LIBRARIES := \

liblog \

libhidlbase \

libutils \

android.hardware.naruto@1.0 \

include $(BUILD_EXECUTABLE)

3.在manifest文件里添加vendor接口的定义，不然在client端是没法拿到service的，在相应的manifest.xml里面加入

# emacs manifest.xml

…

<name>android.hardware.naruto</name>

<transport>hwbinder</transport>

<name>INaruto</name>

<instance>default</instance>

</interface>

</hal>

# adb push manifest.xml /vendor
