ActivityManager：启动Intent {act = android.intent.action.MAIN cat = [android.intent.category.HOME]}

I have a app on my android device that runs as a system_process.

我的Android设备上有一个应用程序作为system_process运行。

It's doing USB communication in JNI layer, with a full screen UI to show images.

它在JNI层进行USB通信,使用全屏UI显示图像。

The problem is, the activity becomes invisible not long after start up. I can see from logcat that the onStop() was called.

问题是,活动在启动后不久就变得不可见了。我可以从logcat看到onStop()被调用。

And when I click the app icon the make it foreground, it would disappear again later.

当我点击应用程序图标使其成为前景时,它将在以后再次消失。

I looked into the logcat to find that when this happens, there is a message like:

我查看了logcat,发现当发生这种情况时,会出现如下消息:

ActivityManager: Start Intent { act=android.intent.action.MAIN cat=[android.intent.category.HOME]}

I don't know whether this means the home key is pressed.

我不知道这是否意味着按下了主页键。

Actually I was not pressing that. But this indeed makes my app goes background and the home page was showed.

其实我并没有按下那个。但这确实使我的应用程序成为背景并显示主页。

I try to add "android.intent.category.HOME" in my AndroidManifest.xml. It does not work.

我尝试在AndroidManifest.xml中添加“android.intent.category.HOME”。这是行不通的。

My question is, what triggers ActivityManager to "Start Intent { act=android.intent.action.MAIN cat=[android.intent.category.HOME]}" ?

我的问题是,什么触发ActivityManager“Start Intent {act = android.intent.action.MAIN cat = [android.intent.category.HOME]}”?

It seems the event is raise at random time.

看来这个事件是随机提升的。

Can I capture & ignore this event to prevent my app from becoming invisible ?

我可以捕获并忽略此事件以防止我的应用程序变得不可见吗?

By the way, my device has android 4.1.2 version.

顺便说一下,我的设备有android 4.1.2版本。

All right. Seems there is something wrong with my device. When I run the app on other device, I did not encounter this problem.

行。好像我的设备有问题。当我在其他设备上运行应用程序时,我没有遇到此问题。
