What does it mean with bug report captured in android tablet?

Question

I was playing around with my tablet and testing my program, when there was a notification that said bug report captured and whether I would like to share it. I had not seen this message before so I clicked Yes, and then I clicked OK on the warning dialog box that asked me to share it only with people I trust. After that the gmail app opened up which had a screenshot of my tablet, as well as a file attached to it called bugreport<some numbers, date and time I think>.txt. I did not send the bug report as I was not sure what it was and where it would go. However my question is,

what exactly is this bug report?

Is it generated by the code that I was testing? Or is it generated by the android system itself?

Did I trigger something unknowingly when I pressed the hardware buttons (the tablet only has 3 hardware buttons, volume up/down and power)?

I have been trying but I cannot make that message appear again, and when I search for bug*.txt using my file viewer app, I cannot find the file. Where is that .txt fil that got attached to the bug report get saved on my tablet?

It's because you have turned on USB debugging in Developer Options. You can create a bug report by holding the power + both volume up and down.

Edit: This is what the forums say:

By pressing Volume up + Volume down + power button, you will feel a vibration after a second or so, that's when the bug reporting initiated.

To disable:

/system/bin/bugmailer.sh must be deleted/renamed.

There should be a folder on your SD card called "bug reports".

I am trying but I can't make it happen again – Broadminded

where can I find the txt file and the screenshot that it had tried to attach before? – Broadminded

What device are using? – Bluefarb

well I don't want to disable the feature as long as it notifies me and does not send any data on the Internet without my explicit permission. Thank you for your help – Broadminded

Anyway, I cannot find /bugmailer.sh in /system/bin/. And I cannot make the bugreport message appear again. but there does seem to be a file called bugreport in /system/bin/, but when I try to open it using a notepad like programi n my file explorer app, it just shows diamond symbols and few texts. It gives a warnign message that this file is encoded in Unicode and the text editor does not support Unicode – Broadminded

Maybe its to late and of little use for you, but the file you have found is a binary File. Probably the executable that generates the bug report. – Culture

Makes sense. I was trying to take a screenshot when this happened – Performance

This happened to me once, when I was trying to take a screenshot. For the record, there was a "Bug report captured" notification, then it said "Only share with people/apps you trust". After reading the above answer, I tried and failed to reproduce it; instead I managed to force-reboot my phone! I won't be trying that again unless/until I have any use for these bug reports! – Russ

What if I don't have an SD card? – Neona
