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： [java] view plain copy <activity android:name=".MainActivity" android:label="@string/app_name"> <intent-filter> <actionandroid:name="android.intent.action.MAIN"/> <categoryandroid:name="android.intent.category.LAUNCHER"/> </intent-filter> </activity> <service android:name="ServiceOne" android:process=":remote"> <intent-filter> <actionandroid:name="com.example.servicedemo.ServiceOne"/> </intent-filter> </service> <service android:name="ServiceTwo" android:process=":remote"> <intent-filter> <actionandroid:name="com.example.servicedemo.ServiceTwo"/> </intent-filter> </service> MainActivity.java： [java] view plain copy packagecom.example.servicedemo; importjava.util.ArrayList; importandroid.app.Activity; importandroid.app.ActivityManager; importandroid.app.ActivityManager.RunningServiceInfo; importandroid.content.Context; importandroid.content.Intent; importandroid.os.Bundle; publicclassMainActivityextendsActivity{ @Override protectedvoidonCreate(BundlesavedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); IntentserviceOne=newIntent(); serviceOne.setClass(MainActivity.this,ServiceOne.class); startService(serviceOne); IntentserviceTwo=newIntent(); serviceTwo.setClass(MainActivity.this,ServiceTwo.class); startService(serviceTwo); } publicstaticbooleanisServiceWorked(Contextcontext,StringserviceName){ ActivityManagermyManager=(ActivityManager)context.getSystemService(Context.ACTIVITY_SERVICE); ArrayList<RunningServiceInfo>runningService=(ArrayList<RunningServiceInfo>)myManager.getRunningServices(Integer.MAX_VALUE); for(inti=0;i<runningService.size();i++){ if(runningService.get(i).service.getClassName().toString().equals(serviceName)){ returntrue; } } returnfalse; } } ServiceOne.java： [java] view plain copy packagecom.example.servicedemo; importjava.util.Timer; importjava.util.TimerTask; importandroid.app.Service; importandroid.content.Intent; importandroid.os.IBinder; importandroid.util.Log; publicclassServiceOneextendsService{ publicfinalstaticStringTAG="com.example.servicedemo.ServiceOne"; @Override publicintonStartCommand(Intentintent,intflags,intstartId){ Log.e(TAG,"onStartCommand"); thread.start(); returnSTART_STICKY; } Threadthread=newThread(newRunnable(){ @Override publicvoidrun(){ Timertimer=newTimer(); TimerTasktask=newTimerTask(){ @Override publicvoidrun(){ Log.e(TAG,"ServiceOneRun:"+System.currentTimeMillis()); booleanb=MainActivity.isServiceWorked(ServiceOne.this,"com.example.servicedemo.ServiceTwo"); if(!b){ Intentservice=newIntent(ServiceOne.this,ServiceTwo.class); startService(service); Log.e(TAG,"StartServiceTwo"); } } }; timer.schedule(task,0,1000); } }); @Override publicIBinderonBind(Intentarg0){ returnnull; } } ServiceTwo.java： [java] view plain copy packagecom.example.servicedemo; importjava.util.Timer; importjava.util.TimerTask; importandroid.app.Service; importandroid.content.Intent; importandroid.os.IBinder; importandroid.util.Log; publicclassServiceTwoextendsService{ publicfinalstaticStringTAG="com.example.servicedemo.ServiceTwo"; @Override publicintonStartCommand(Intentintent,intflags,intstartId){ Log.e(TAG,"onStartCommand"); thread.start(); returnSTART_REDELIVER_INTENT; } Threadthread=newThread(newRunnable(){ @Override publicvoidrun(){ Timertimer=newTimer(); TimerTasktask=newTimerTask(){ @Override publicvoidrun(){ Log.e(TAG,"ServiceTwoRun:"+System.currentTimeMillis()); booleanb=MainActivity.isServiceWorked(ServiceTwo.this,"com.example.servicedemo.ServiceOne"); if(!b){ Intentservice=newIntent(ServiceTwo.this,ServiceOne.class); startService(service); } } }; timer.schedule(task,0,1000); } }); @Override publicIBinderonBind(Intentarg0){ returnnull; } } 本文转自农夫山泉别墅博客园博客，原文链接：http://www.cnblogs.com/yaowen/p/5673965.html，如需转载请自行联系原作者
