Public methodspublic void logEvent(@NonNull @Size(min = 1, max = 40) String name, @Nullable Bundle params)
Logs an app event. The event can have up to 25 parameters. Events with the same name must have the same parameters. Up to 500 event names are supported. Using predefined Event
and/or Param
is recommended for optimal reporting.
@NonNull @Size(min = 1, max = 40) String name
The name of the event. Should contain 1 to 40 alphanumericcharacters or underscores. The name must start with an alphabeticcharacter. Some event names are reserved. See Event
for the list of reserved event names. The "firebase_", "google_" and "ga_" prefixes are reserved and should not be used. Note that event names are case-sensitive and that logging two events whose names differ only in case will result in two distinct events.
@Nullable Bundle params
The map of event parameters. Passing null indicates that the event has no parameters. Parameter names can be up to 40 characters long and must start with an alphabeticcharacter and contain only alphanumericcharacters and underscores. String, long and double param types are supported. String parameter values can be up to 100 characters long. The "firebase_", "google_" and "ga_" prefixes are reserved and should not be used for parameter names.
public void resetAnalyticsData()
Clears all analytics data for this app from the device and resets the app instance id.
setAnalyticsCollectionEnabledpublic void setAnalyticsCollectionEnabled(boolean enabled)
Sets whether analytics collection is enabled for this app on this device. This setting is persisted across app sessions. By default it is enabled.
Parametersboolean enabled
Whether analytics collection is enabled for this app on this device.
@MainThreadThis method is deprecated.
@Keep
public void setCurrentScreen(
@NonNull Activity activity,
@Nullable @Size(min = 1, max = 36) String screenName,
@Nullable @Size(min = 1, max = 36) String screenClassOverride
)
To log screen view events, call mFirebaseAnalytics.logEvent(FirebaseAnalytics.Event.SCREEN_VIEW, params) instead.
Sets the current screen name, which specifies the current visual context in your app. This helps identify the areas in your app where users spend their time and how they interact with your app.
Note that screen reporting is enabled automatically and records the class name of the current Activity for you without requiring you to call this function. The class name can optionally be overridden by calling this function in the onResume callback of your Activity and specifying the screenClassOverride parameter.
If your app does not use a distinct Activity for each screen, you should call this function and specify a distinct screenName each time a new screen is presented to the user.
The name and classOverride remain in effect until the current Activity changes or a new call to setCurrentScreen is made.
This method must be called from the app's main thread.
Parameters@NonNull Activity activity
The activity to which the screen name and class name apply.
@Nullable @Size(min = 1, max = 36) String screenName
The name of the current screen. Set to null to clear the current screen name.
@Nullable @Size(min = 1, max = 36) String screenClassOverride
The name of the screen class. By default this is the class name of the current Activity. Set to null to revert to the default class name.
setDefaultEventParameterspublic void setDefaultEventParameters(@Nullable Bundle parameters)
Adds parameters that will be set on every event logged from the SDK, including automatic ones. The values passed in the parameters bundle will be added to the map of default event parameters. These parameters persist across app runs. They are of lower precedence than event parameters, so if an event parameter and a parameter set using this API have the same name, the value of the event parameter will be used. The same limitations on event parameters apply to default event parameters.
Parameters@Nullable Bundle parameters
Parameters to be added to the map of parameters added to every event. They will be added to the map of default event parameters, replacing any existing parameter with the same name. Valid parameter values are String
, long
, and double
. Setting a key's value to null
will clear that parameter. Passing in a null
bundle will clear all parameters.
public void setSessionTimeoutDuration(long milliseconds)
Sets the duration of inactivity that terminates the current session. The default value is 1800000 (30 minutes).
Parameterslong milliseconds
Session timeout duration in milliseconds
public void setUserId(@Nullable String id)
Sets the user ID property. This feature must be used in accordance with Google's Privacy Policy.
Parameters@Nullable String id
The user ID to ascribe to the user of this app on this device, which must be non-empty and no more than 256 characters long. Setting the ID to null removes the user ID.
public void setUserProperty(
@NonNull @Size(min = 1, max = 24) String name,
@Nullable @Size(max = 36) String value
)
Sets a user property to a given value. Up to 25 user property names are supported. Once set, user property values persist throughout the app lifecycle and across sessions.
Parameters@NonNull @Size(min = 1, max = 24) String name
The name of the user property to set. Should contain 1 to 24 alphanumericcharacters or underscores and must start with an alphabeticcharacter. The "firebase_", "google_" and "ga_" prefixes are reserved and should not be used for user property names.
@Nullable @Size(max = 36) String value
The value of the user property. Values can be up to 36 characters long. Setting the value to null removes the user property.
Extension functionspublic final void AnalyticsKt.setConsent(This method is deprecated.
@NonNull FirebaseAnalytics receiver,
@ExtensionFunctionType @NonNull Function1<@NonNull ConsentBuilder, Unit> block
)
Fluent version of FirebaseAnalytics.setConsent
.
Example use:
Firebase.analytics.setConsent {
adStorage = ConsentStatus.GRANTED
analyticsStorage = ConsentStatus.GRANTED
}
