＆QUOT;坠毁服务＆QUOT;但是到ONSTART没有呼叫调度启动（）如下 [英] "Scheduling restart of crashed service", but no call to onStart() follows

问题描述

在1.6 API，是有办法，以确保服务的ONSTART（）方法被调用后，该服务因杀害内存pressure？从日志，似乎过程的服务属于重新启动，但是服务本身是没有的。我已经放置了一个Log.d（）调用在ONSTART（）方法，这是没有达到

要在内存pressure测试我的服务，我从活动中产卵，然后启动Web浏览器并访问像Slashdot的一些JavaScript重的网站，直到我的服务被杀害。该logcat的内容如下：

  03-07 16：44：13.778：信息/ ActivityManager（52）：过程com.kostmo.charbuilder.full（PID 2909）已死亡。
03-07 16：44：13.778：WARN / ActivityManager（52）：坠毁服务com.kostmo.charbuilder.full调度启动/ com.kostmo.charbuilder.DownloadImagesService在5000毫秒

解决方案

所揭示的Chistopher的上述评论，即使日志声称是应声服务安排重新启动 ，这实际上并不意味着 ONSTART（）方法将被调用。然而，的onCreate（）的确会叫，你的应用程序可以调用 ONSTART（）从那里。

In the 1.6 API, is there a way to ensure that the onStart() method of a Service is called after the service is killed due to memory pressure? From the logs, it seems that the "process" that the service belongs to is restarted, but the service itself is not. I have placed a Log.d() call in the onStart() method, and this is not reached.

To test my service under memory pressure, I spawn it from an activity, then launch the web browser and visit some Javascript-heavy websites like Slashdot until my service is killed. The logcat reads:

03-07 16:44:13.778: INFO/ActivityManager(52): Process com.kostmo.charbuilder.full (pid 2909) has died.

解决方案

As revealed by Chistopher's comment above, even though the log purports to be "Scheduling restart of crashed service", this does not actually mean that the onStart() method will be called. However, onCreate() will indeed be called, and your application can call onStart() from there.
