三种方法让你的Service不被“一键加速”和系统杀掉

基本上大家都知道提高service优先级能够在非常大程度上让你的service免于由于内存不足而被kill，当然系统仅仅是在此时先把优先级低的kill掉，假设内存还是不够，也会把你的service干掉的. 1.android:persistent="true" 常驻内存属性对第三方app无效。以下是官方说明 android:persistent

    Whether or not the application should remain running at all times — "true" if it should, and "false" if not. The default value is "false". Applications should not normally set this flag; persistence mode is intended only for certain system applications.

2.startForeground将其放置前台

Notification notification = new Notification(); notification.flags = Notification.FLAG_ONGOING_EVENT; notification.flags |= Notification.FLAG_NO_CLEAR; notification.flags |= Notification.FLAG_FOREGROUND_SERVICE; startForeground(1, notification); 3.能够监听Intent.ACTION_TIME_TIC系统时钟广播。系统每隔一段时间发送这个广播。当service被杀死的时候，隔一段时间通过广播启动   动态注冊android.intent.action.TIME_TICK监听   推断service是否启动

public boolean isServiceRunning(String serviceName) { ActivityManager manager = (ActivityManager)getSystemService(Context.ACTIVITY_SERVICE); for (RunningServiceInfo service :manager.getRunningServices(Integer.MAX_VALUE)) { if(serviceName.equals(service.service.getClassName())) { return true; } } return false; }  接受到广播后推断是否启动该service 若没有启动就启动它

if(intent.getAction().equals(Intent.ACTION_TIME_TICK)) { if (!isServiceRunning(name)) { Intent mIntent = new Intent(context, MyService.class); context.startService(mIntent); } }
