Android - 当ActivityManager重新启动后台系统服务调度时，前台Activity被杀死

发布于 2024-12-11 07:42:05 字数 19947 浏览 0 评论 0原文

我有一个查看器应用程序，使用 Android 兼容包中的 ImageView 和 ViewPager 实现。对于每个页面，我渲染一些 Bitmap 并将它们放入 ViewPager 中。它工作正常，但有时应用程序只是崩溃，没有异常，也没有寄存器转储。我注意到，通常情况下，应用程序不会崩溃，只是记录许多 GC 消息。但是当系统ActivityManager开始安排重启某些后台系统Service时，应用程序在页面之间切换时很有可能崩溃。

我搜索了一些问题，但都是关于 Service 由于内存不足而被终止，由于状态不一致而重新启动失败，或者其他什么。但就我而言，前台 Activity 被杀死，只是因为某些系统服务被安排重新启动。前台 Activity 怎么可能被“后台服务”杀死？

虽然在日志中，服务似乎因内存不足而重新启动失败，但我的活动只是被杀死，没有出现 OutOfMemoryError 错误。我不知道导致我的应用程序被杀死的真正问题是什么......

PS。如果我不在页面之间切换，应用程序将存活，但系统会重复安排重新启动服务。在这种情况下，应用程序在页面之间切换时很容易崩溃。

PS2。设备是：ASUS Transformer TF101，Android 3.2，内核版本：2.6.36.3-00003-g9baf8f7

这是日志，mycompany.viewer.MagazineActivity 是主要 Activity：

PS3。一些其他日志来描述崩溃进度

然后系统开始调度重启，有的成功，有的失败，如此反复。顺便说一句，com.google.android.music/.dl.DownloadManager$DownloadManagerService和com.google.android.apps.maps/com.google.android.location.internal.server.NetworkLocationService总是重启失败。

日志看起来像是“调度重新启动...”、“启动进程...”、“GC ...”的混合，

如果我在页面之间切换，更多服务被杀死，系统仍然调度重复重新启动。

又切换了一些页面，最后应用程序崩溃了，正如最上面的日志一样。

原文

I have a viewer application, implement with ImageView and ViewPager from Android Compatibility Package. For each page, I render some Bitmap and put them into ViewPager. It works fine, but sometimes the application just crashed without exception nor register dump. I noticed that, normally, the application didn't crash, just log many GC messages. But when system ActivityManager start to schedule restart some background system Service, the application get a big chance to crash when switching between pages.

I searched some questions, but they are about Service being killed because of low memory, restart failed because of state inconsistency, or something. But in my case, It's foreground Activity being killed, just because some system Services were scheduled restart. How could a foreground Activity being killed "by background Service"?

Although in log, the Services seem to restart failed because of low memory, but my Activity just being killed without OutOfMemoryError. I can't figure out what is the real problem caused my application being killed...

PS. If I don't switch between pages, the application lives, but system is scheduling restart Services repeatedly. In this situation, the application is easy to crash when switching between pages.

PS2. device is: ASUS Transformer TF101, Android 3.2, Kernel version: 2.6.36.3-00003-g9baf8f7

Then the system begins to scheduling restart, success some, failed some, repeatedly. Btw, com.google.android.music/.dl.DownloadManager$DownloadManagerService and com.google.android.apps.maps/com.google.android.location.internal.server.NetworkLocationService always failed to restart.

Log looks like mix of "Scheduling restart...", "Start proc...", "GC ..."

If I switch between pages, more Services are killed, system still scheduling restart repeatedly.
