Automatically captured data

BugSnag automatically captures a variety of data to help you debug your errors. You may wish to avoid capturing some types of data, particularly if there are privacy implications for your users.

User information

User information is used to show you which errors are impacting the most users. Set your own user identifiers if you want to be able to find errors affecting individual users.

If no user ID is set on the Bugsnag client, a BugSnag-generated Device ID is used for the user.id property of Event and Session objects. To prevent collection, set an initial value in the Bugsnag client or update the data in an OnErrorCallback and OnSessionCallback.

Device information

Information about the device can be useful to identify if an error is only occurring on some devices.

To see the data collected about a user’s device, see the device property of the Event and Session classes. To prevent collection, update the data in an OnErrorCallback and OnSessionCallback.

In addition, the following data is collected and added to the metadata field of an Event. This data can be removed by clearing the following keys from metadata:

Section	Key	Description
device	batteryLevel	The battery level on the device when the event occurred
device	brand	The brand of device
device	charging	Whether the device was charging when the event occurred
device	dpi	The screen density scaling factor of the device in DPI
device	emulator	Whether the device was an emulator
device	locationStatus	The status of location services when the event occurred
device	networkAccess	The type of network in use on the device when the event occurred
device	screenDensity	The screen density scaling factor of the device
device	screenResolution	The resolution of the device’s screen

Application information

Information about the application can be useful to identify if an error occurs in certain versions.

To see the data collected about your app, see the app property of the Event and Session classes. To prevent collection, update the data in an OnErrorCallback and OnSessionCallback.

In addition, the following data is collected and added to the metadata field of an Event. This data can be removed by clearing the following keys from metadata:

Section	Key	Description
app	activeScreen	The screen name of the current foreground Activity
app	backgroundWorkRestricted	Whether the user has enabled background work restrictions. This determines whether scheduled jobs and alarms can execute
app	freeMemory	The amount of memory available to be allocated by the app (in bytes)
app	lowMemory	Whether the system is running in a low memory situation
app	memoryLimit	The maximum amount of memory which can be allocated by the app (in bytes)
app	memoryTrimLevel	The most recently received memory trim level
app	memoryUsage	The amount of memory allocated by the app (totalMemory - freeMemory)
app	name	The name of the app from the manifest
app	processName	The process name from the manifest
app	totalMemory	The amount of memory allocated by the Android Runtime (in bytes)

Error information

Modifying error information may affect error grouping.

To see the data collected about a captured error (Throwable), see the errors property of the Event class. To prevent collection, update the data in an OnErrorCallback.

Breadcrumbs

Breadcrumbs are automatically recorded for common actions and can be helpful to reproduce errors.

The following breadcrumbs are collected and can be filtered/amended in an OnBreadcrumbCallback or disabled by its type using enabledBreadcrumbTypes:

onActivityStarted	State	When an Activity receives the onStart lifecycle callback
