framework添加自己的服务

http://www.360doc.com/content/12/0719/19/87000_225297295.shtml 借鉴

1  frameworks/base/core/java/android/os 中添加Ismackserviec.aidl 

package android.os;interface Ismackservice{    boolean seton();}

2 修改/frameworks/base/Android.mk 添加     core/java/android/os/Ismackservice.aidl ，使其得到编译

3 frameworks/base/services/java/com/android/server 中添加smack_service.java

package com.android.server;import android.content.Context;import android.os.Ismackservice;import java.io.IOException;import android.util.Log;import java.io.BufferedReader;import java.io.InputStreamReader;public final class smack_service extends Ismackservice.Stub{        public static final String TAG = "smack_service";        smack_service(Context context){                Log.i(TAG,"GET smack_service_stub");        }        public boolean set_net_on(){                Log.i(TAG,"set net on");                 set_net_on_jni();/*                 String s = "\n";                  try{                                 Process p =Runtime.getRuntime().exec("echo ^ > /smack/ambient");                                 BufferedReader in = new BufferedReader(                           new InputStreamReader(p.getErrorStream()));       String line = null;       while ((line = in.readLine()) != null) {           s += line + "\n";                  }       Log.i(TAG,s);                                                                  }                                 catch (IOException e) {                                        // TODO Auto-generated catch block                                                        e.printStackTrace();                                }*/                return true;        }            public boolean set_net_off(){                Log.i(TAG,"set net off");            set_net_off_jni();                return true;        }     private static native void set_net_on_jni();     private static native void set_net_off_jni();}

4 修改frameworks/base/services/java/com/android/server/SystemServer.java 注册smack_service

             Slog.i(TAG, "smack_service");
             ServiceManager.addService(Context.SMACK_SERVICE,new smack_service(context));

修改 frameworks/base/core/java/android/content/Context.java

public static final String SMACK_SERVICE = "smack";//xiayu fix

5 make_updata-api     mmm framework/base/services/java     m

6 编写测试apk , 在eclipse中,右键-》Buid Path->Configure Build Path->Libraries->Add External Jars

    out/target/common/obj/JAVA_LIBRARIES/framework_intermediates/classes.jar
