大佬教程收集整理的这篇文章主要介绍了android – 崩溃的服务在很长一段时间后重新启动,大佬教程大佬觉得挺不错的,现在分享给大家,也给大家做个参考。
11-15 15:39:48.756: W/Activitymanager(375): scheduling restart of crashed service com.example.app/com.example.Sensorservice in 1019562ms
// How long we wait for a service to finish execuTing. static final int serviCE_TIMEOUT = 20*1000; // How long a service needs to be running until restarTing its process // is no longer considered to be a relaunch of the service. static final int serviCE_RESTART_DURATION = 5*1000; // How long a service needs to be running until it will start BACk at // serviCE_RESTART_DURATION after being killed. static final int serviCE_RESET_RUN_DURATION = 60*1000; // Multiplying factor to increase restart duration time by,for each time // a service is killed before it has run for serviCE_RESET_RUN_DURATION. static final int serviCE_RESTART_DURATION_FACTOR = 4; // The minimum amount of time @R_262_7000@n restarTing services that we allow. // That is,when multiple services are restarTing,we won't allow each // to restart less than this amount of time from the last one. static final int serviCE_MIN_RESTART_TIME_@R_262_7000@N = 10*1000; // Maximum amount of time for there to be no activity on a service before // we consider it non-essential and allow its process to go on the // LRU BACkground list. static final int MAX_serviCE_INACTIVITY = 30*60*1000;
你发生的事情可能是你的服务比serviCE_RESET_RUN_DURATION快死,然后重启时间乘以serviCE_RESTART_DURATION_FACTOR.
从第881行开始:
// If it has been a "reasonably long time" since the service // was started,then reset our restart duration BACk to // the beginning,so we don't infinitely increase the duration // on a service that just occasionally gets killed (which is // a normal case,due to process being killed to reclaim memory). if (Now > (r.restartTime+resetTimE)) { r.restartCount = 1; r.restartDelay = minDuration; } else { if ((r.serviceInfo.applicationInfo.flags &ApplicationInfo.FLAG_PERSISTENT) != 0) { // services in peristent processes will restart much more // quickly,since they are pretty important. (Think systemUI). r.restartDelay += minDuration/2; } else { r.restartDelay *= serviCE_RESTART_DURATION_FACTOR; if (r.restartDelay < minDuration) { r.restartDelay = minDuration; } } }
下面的行将支持您的服务.
r.restartDelay *= serviCE_RESTART_DURATION_FACTOR;
因此,如果您的服务在运行serviCE_RESET_RUN_DURATION之前死亡,您应该修复此案例.
