手机待命后程序不再运行

Question

Android 2.1使用了timer schedule 隔一段时间执行,但有时手机待命后(关了屏),程序再不执行
查看过程序没被kill,怎样可以令到程序持续运行?
@Override
public void onCreate(Bundle savedInstanceState) {
        
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Timer timer=new Timer();
        timer.schedule(new TimerTask(){
        int r = 1;         @Override
        public void run(){
                        doProcess(); //run process
     saveLog(r);//save log into sd card
     r++;
        }
        },0,60000);
}
权限设定    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.VIBRATE" />
    <uses-permission android:name="android.permission.WAKE_LOCK /">
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Answer 1

用service吧,很简单
public class MyService extends Service{
@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
} @Override
public void onCreate() {
// TODO Auto-generated method stub
super.onCreate();
} @Override
public void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
} @Override
public int onStartCommand(Intent intent, int flags, int startId) {
// TODO Auto-generated method stub
return super.onStartCommand(intent, flags, startId);
} @Override
public void onStart(Intent intent, int startId) {
 setContentView(R.layout.main);
        Timer timer=new Timer();
        timer.schedule(new TimerTask(){
            int r = 1;            @Override
            public void run(){
                        doProcess(); //run process
                saveLog(r);//save log into sd card
                r++;
            }
        },0,60000); }
}
AndroidManifest.xml中记得配置<service
android:name=".MyService">
</service>

谢谢，但怎样检查Service正在执行?现在把startService()放在Activity的onCreate里，再开app时，Service会再重新启动
