Android--launch service across apps

This chapter blog, which records the launch service across apps.
We need to create an application Service1, which contains a myservice, some of the code is as follows:

    @Override    publicvoidonCreate() {        // TODO Auto-generated method stub        System.out.println("onCreate");        super.onCreate();    }    @Override    publicvoidonDestroy() {        System.out.println("onDestroy");        super.onDestroy();    }

Previous blogs have introduced the Create service, which can be referenced in Create: http://blog.csdn.net/gaopeng0071/article/details/45153495

Then create a Service2 app. The activity code is as follows,
We note 21 lines of code, the first parameter in the ComponentName object is the service package name to jump to the app, and the second parameter is the full path of the service class.

 PackageCom.example.service2;Importandroid.app.Activity;ImportAndroid.content.ComponentName;ImportAndroid.content.Intent;ImportAndroid.os.Bundle;ImportAndroid.view.Menu;ImportAndroid.view.View;ImportAndroid.view.View.OnClickListener; Public  class mainactivity extends Activity implements Onclicklistener  {Intent serviceintent;@Override    protected void onCreate(Bundle savedinstancestate) {Super. OnCreate (Savedinstancestate);        Setcontentview (R.layout.activity_main); Serviceintent =NewIntent (); Serviceintent.setcomponent (NewComponentName ("Com.example.service1","Com.example.service1.MyService")); Findviewbyid (R.id.button1). Setonclicklistener ( This); Findviewbyid (R.id.button2). Setonclicklistener ( This); }@Override     Public Boolean Oncreateoptionsmenu(Menu menu) {//inflate the menu; This adds items to the action bar if it is present.Getmenuinflater (). Inflate (R.menu.main, menu);return true; }@Override     Public void OnClick(View v) {Switch(V.getid ()) { CaseR.id.button1:startservice (serviceintent); Break; CaseR.id.button2:stopservice (serviceintent); Break; }    }}
