Crash after 40 minutes of background running

[skymoomy]

HI,all:
I use SimpleUsbTerminal-master and make some changes to this project:
1.use usbSerialForAndroid of usb-serial-for-android-master instead of 'com.github.mik3y:usb-serial-for-android:3.8.0' to support my usb device
2.add some log print

I have encountered a recurring problem, sending command to enable log capture per second, and pressing the HOME key to switch the APP to the background, the app will run normally for a while。But , after about 40 minutes，the notification icon will suddenly disappears and the APP crashes.The log is as follows。Please help to check what caused the crash. Thank you

the SerialService queues all data while in background and shows it in the Text view when the App gets visible again.
The App might have been crashed with out of memory.
Showing very large text is incredibly slow, so don't do it.
If your main purpose is logging, you should write to a file in SerialService.onSerialRead and limit the queue size to show only the last data.
