Android calls between different processes AIDL implementation of communication services

Android calls between different processes AIDL implementation of communication services
      recent calls to different processes in Aidl Android have made some attempts to make calls between different applications:The steps are as follows:1: First write the service services in the program to be called

The specific code is as follows:

Package Com.jiaruihua.service.demo;import Android.app.service;import Android.content.intent;import Android.os.binder;import Android.os.ibinder;public class Alipayservice extends Service {@Overridepublic IBinder onbind (Intent Intent) {//TODO auto-generated method stubSystem.out.println ("Remote service is bound"); <span style= "color: #ff0000;" >//note here to return to our ibinder</span>return new Mybinder ();} @Overridepublic boolean onunbind (Intent Intent) {//TODO auto-generated method stubSystem.out.println ("Remote service has been lifted"); return Super.onunbind (intent);} @Overridepublic void OnCreate () {//TODO auto-generated method stubSystem.out.println ("remote service created"); Super.oncreate ();} @Overridepublic void OnDestroy () {//TODO auto-generated method stubSystem.out.println ("Remote service destroyed"); Super.ondestroy (); /*

*<span style= "color: #ff0000;" > Here is the method to be called by remote, function processing here </span> * Payment Operation */public void Paymoney () {System.out.println ("payment operation");} /*

* Here we need a iservice.stub, which is what we define ISERVICE.AIDL, implemented, see step two * Iservice.stub has implemented Binder  */public class Mybinder extends <span style= "color: #ff0000;" >iservice.stub</span>{@Overridepublic void Callmethodservice () {Paymoney ();}}}

2: Create a Iservice.aidl file required in the previous step


The code is as follows:

The package Com.jiaruihua.service.demo;//aidl interface definition does not require the access modifier default public interface IService {void Callmethodservice ();}

The Iservice.java file is automatically created in the Gen directory in eclipse
3: Register in the Mainfest.xml file IService
4: Create a package in another program that needs to be called, note that the package name here is consistent with the specified package name of the service in the mainfest.xml above;Let's copy the Iservice.aidl file created by the second step above .


5: Call Remote service

Package Com.example.mygameapp;import Com.jiaruihua.service.demo.iservice;import Android.app.activity;import Android.app.service;import Android.content.componentname;import Android.content.intent;import Android.content.serviceconnection;import Android.os.bundle;import Android.os.ibinder;import Android.os.remoteexception;import Android.view.view;import Android.view.view.onclicklistener;public Class Mainactivity extends Activity {private Intent intent;private iservice iservice; @Overrideprotected void OnCreate (Bundle Savedinstancestate) {super.oncreate (savedinstancestate); Setcontentview (r.layout.activity_main); intent = new Intent (); <span style= "color: #ff0000;" >//the action here must be one to </span>intent.setaction ("Com.jiaruihua.ServicePay") that you set in the calling program; Bind service Findviewbyid (r.id.banding). Setonclicklistener (New Onclicklistener () {@Overridepublic void OnClick (View arg0) { <span style= "color: #ff0000;" >//Bind Service Open service </span>bindservice (intent, New MyConn (), bind_auto_create);}); &lT;span style= "color: #ff0000;" >//calls remote method </span>findviewbyid (R.id.callmethod). Setonclicklistener (New Onclicklistener () {@Overridepublic void OnClick (View arg0) {//TODO auto-generated method stubtry {iservice.callmethodservice ();} catch (RemoteException e) { TODO auto-generated catch Blocke.printstacktrace ();}});} Private class MyConn implements Serviceconnection {//successfully bound @overridepublic void onserviceconnected (componentname name, IBinder service) {<span style= "color: #ff0000;" >//convert SERCICSE to IService interface type IService = Iservice.Stub.asInterface (service); </span> @Overridepublic void onservicedisconnected (componentname name) {//TODO auto-generated Method stub}}}
