android應用多線程守護讓你非常難殺死它

標籤：set   created   art   eth   thread   守護   bin   call   this   

1、android 應用開啟後啟動一個服務

public class TestserviceActivity extends Activity {

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
System.out.println("activity執行的線程id:"+ Thread.currentThread().getName() +"--"+
Thread.currentThread().getId());
System.out.println("activity的進程id:"+android.os.Process.myPid());
        
        Intent intent = new Intent(this,Service1.class);
        startService(intent);
    }

}

2、第一個服務

public class Service1 extends Service {


@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}

@Override
public void onCreate() {
// TODO Auto-generated method stub
System.out.println("服務1 被開啟");
System.out.println("服務執行的線程id:"+ Thread.currentThread().getName() +"--"+
Thread.currentThread().getId());
System.out.println("服務的進程id:"+android.os.Process.myPid());
super.onCreate();
}

@Override
public void onDestroy() {
Intent intent = new Intent(this,Service2.class);
startService(intent);
super.onDestroy();
}


}

3、第2個服務

public class Service2 extends Service {


@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
@Override
public void onCreate() {
System.out.println("服務2 被開啟");
super.onCreate();
}

@Override
public void onDestroy() {
Intent intent = new Intent(this,Service1.class);
startService(intent);
super.onDestroy();
}
}

4、資訊清單檔裡

 <service android:name=".Service1"
            android:process="cn.it.yqq"
            ></service>
        <service android:name=".Service2"></service>
