仿照instaled寫的

1、聲明?? 在system/core/rootdir/init.rc中添加:

service testlang /system/bin/testlang

#?????? 名稱??????? 路徑

class main

socket dumpstate stream 0660 shell log

#disabled 沒有立馬啟用

#oneshot 如果用這個參數說明只啟動一次

2、實現??? 在frameworks/base/cmds/添加testlang文件夾

testlang.h 內容：

#define LOG_TAG "testlang"

#include

#include

#include

#include

#include

#define MY_SOCKET_PATH "testlang"

testlang.c 內容：

#include "testlang.h"

#define LOG_NDEBUG 0

#define LOG_NDDEBUG 0

#define LOG_NVDEBUG 0

static int read_testlang(int fd, void* _buf, size_t count){

int r;

char *buf = _buf;

r = read(fd,buf,count);

LOGD("langxw buf = %s",*buf);

return 0;

}

int main(int argc, char** argv){

LOGE("langxw testlang main");

char buf[1];

struct sockaddr addr;

socklen_t alen;

int mysocket, s, count;

LOGD("langxw A/N mysocket? = %d, s = %d, count = %d\n",mysocket, s, count);

if(argc==2){

LOGD("langxw aargv[1] = %s\n",argv[1]);

}else{

LOGD("langxw A/N argc = %d\n",argc);

}

mysocket = android_get_control_socket(MY_SOCKET_PATH);

if(mysocket<0){

LOGE("langxw testlang failed");

printf("langxw failed to get socket , reason %s,\n",strerror(errno));

exit(1);

}else{

LOGE("langxw testlang success");

}

if(listen(mysocket,5)){

LOGE("langxw listten on socket failed\n");

exit(1);

}

fcntl(mysocket, F_SETFD, FD_CLOEXEC);

int timce = -1;

for(;;){

LOGE("langxw timce = %d\n",timce);

alen = sizeof(addr);

s = accept(mysocket, &addr, &alen);

if(s<0){

// LOGE("langxw accept failed:%s\n",strerror(errno));

LOGE("langxw accept failed");

continue;

}else{

LOGE("langxw accept success:%s\n",strerror(errno));

LOGE("langxw accept success");

}

fcntl(s, F_SETFD, FD_CLOEXEC);

LOGE("langxw new connection");

for(;;){

//read_testlang(s,buf,1);

}

LOGE("langxw closing connection");

close(s);

}

LOGE("langxw testlang main end");

return 0;

}

Android.mk 內容：

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE_TAGS := OPTIONAL

LOCAL_MODULE := testlang

LOCAL_SRC_FILES := testlang.c

#log 所需的庫

LOCAL_SHARED_LIBRARIES :=?? libcutils

include $(BUILD_EXECUTABLE)

3、client端：

部分代碼：

import android.net.LocalSocket;

import android.net.LocalSocketAddress;

import java.io.IOException;

import java.io.InputStream;

import java.io.OutputStream;

//langxw add

InputStream mIn;

OutputStream mOut;

LocalSocket mSocket;

private boolean connect() {

if (mSocket != null) {

Log.e(TAG, "langxw already connecting...");

return true;

}

Log.e(TAG, "langxw connecting...");

try {

mSocket = new LocalSocket();

LocalSocketAddress address = new LocalSocketAddress("installd",

LocalSocketAddress.Namespace.RESERVED);

mSocket.connect(address);

mIn = mSocket.getInputStream();

mOut = mSocket.getOutputStream();

} catch (IOException ex) {

Log.i(TAG, "langxw connect failed");

ex.printStackTrace();

disconnect();

return false;

}

return true;

}

private void disconnect() {

Log.i(TAG, "langxw disconnecting...");

try {

if (mSocket != null)

mSocket.close();

} catch (IOException ex) {

}

try {

if (mIn != null)

mIn.close();

} catch (IOException ex) {

}

try {

if (mOut != null)

mOut.close();

} catch (IOException ex) {

}

mSocket = null;

mIn = null;

mOut = null;

}

4、需要android.uid.system權限

在AndroidManifest.xml

xmlns:android="http://schemas.android.com/apk/res/android"

android:sharedUserId="android.uid.system">

APK 的Android.mk文件里面添加

LOCAL_CERTIFICATE := platform

注意：需要全編譯才行
