保持Service不被Kill掉的方法--双Service守护 && Android实现双进程守护 2

保持Service不被Kill掉的方法--双Service守护，代码如下：

AndroidManifest.xml：

<activity
        android:name=".MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <service
        android:name="ServiceOne"
        android:process=":remote" >
        <intent-filter>
            <action android:name="com.example.servicedemo.ServiceOne" />
        </intent-filter>
    </service>

    <service
        android:name="ServiceTwo"
        android:process=":remote" >
        <intent-filter>
            <action android:name="com.example.servicedemo.ServiceTwo" />
        </intent-filter>
    </service>

MainActivity.java：

package com.example.servicedemo;

import java.util.ArrayList;

import android.app.Activity;
import android.app.ActivityManager;
import android.app.ActivityManager.RunningServiceInfo;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Intent serviceOne = new Intent();
        serviceOne.setClass(MainActivity.this, ServiceOne.class);
        startService(serviceOne);

        Intent serviceTwo = new Intent();
        serviceTwo.setClass(MainActivity.this, ServiceTwo.class);
        startService(serviceTwo);
    }

    public static boolean isServiceWorked(Context context, String serviceName) {
        ActivityManager myManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
        ArrayList<RunningServiceInfo> runningService = (ArrayList<RunningServiceInfo>) myManager.getRunningServices(Integer.MAX_VALUE);
        for (int i = 0; i < runningService.size(); i++) {
            if (runningService.get(i).service.getClassName().toString().equals(serviceName)) {
                return true;
            }
        }
        return false;
    }
}

ServiceOne.java：

package com.example.servicedemo;

import java.util.Timer;
import java.util.TimerTask;

import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.util.Log;

public class ServiceOne extends Service {

    public final static String TAG = "com.example.servicedemo.ServiceOne";

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        Log.e(TAG, "onStartCommand");

        thread.start();
        return START_STICKY;
    }

    Thread thread = new Thread(new Runnable() {

        @Override
        public void run() {
            Timer timer = new Timer();
            TimerTask task = new TimerTask() {

                @Override
                public void run() {
                    Log.e(TAG, "ServiceOne Run: "+System.currentTimeMillis());
                    boolean b = MainActivity.isServiceWorked(ServiceOne.this, "com.example.servicedemo.ServiceTwo");
                    if(!b) {
                        Intent service = new Intent(ServiceOne.this, ServiceTwo.class);
                        startService(service);
                        Log.e(TAG, "Start ServiceTwo");
                    }
                }
            };
            timer.schedule(task, 0, 1000);
        }
    });

    @Override
    public IBinder onBind(Intent arg0) {
        return null;
    }

}
