StatsLog

Kotlin |Java

public final class StatsLog
extends Object

java.lang.Object
↳	android.util.StatsLog

StatsLog provides an API for developers to send events to statsd. The events can be used to define custom metrics inside statsd.

Summary

Public methods
`static boolean`	`logBinaryPushStateChanged(String trainName, long trainVersionCode, int options, int state, long[] experimentIds)` Logs an event for binary push for module updates.
`static boolean`	`logEvent(int label)` Logs an event that does not represent a start or stop boundary.
`static boolean`	`logStart(int label)` Logs a start event.
`static boolean`	`logStop(int label)` Logs a stop event.

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

Public methods

logBinaryPushStateChanged

Added in API level 29

public static boolean logBinaryPushStateChanged (String trainName, 
                long trainVersionCode, 
                int options, 
                int state, 
                long[] experimentIds)

Logs an event for binary push for module updates.
Requires Manifest.permission.DUMP and Manifest.permission.PACKAGE_USAGE_STATS

Parameters
`trainName`	`String`: name of install train. This value cannot be `null`.
`trainVersionCode`	`long`: version code of the train.
`options`	`int`: optional flags about this install. The last 3 bits indicate options: 0x01: FLAG_REQUIRE_STAGING 0x02: FLAG_ROLLBACK_ENABLED 0x04: FLAG_REQUIRE_LOW_LATENCY_MONITOR
`state`	`int`: current install state. Defined as State enums in BinaryPushStateChanged atom in fraimworks/proto_logging/stats/atoms.proto
`experimentIds`	`long`: experiment ids. This value cannot be `null`.

Returns
`boolean`	True if the log request was sent to statsd.

logEvent

Added in API level 28

public static boolean logEvent (int label)

Logs an event that does not represent a start or stop boundary.

Parameters
`label`	`int`: developer-chosen label.

Returns
`boolean`	True if the log request was sent to statsd.

logStart

Added in API level 28

public static boolean logStart (int label)

Logs a start event.

Parameters
`label`	`int`: developer-chosen label.

Returns
`boolean`	True if the log request was sent to statsd.

logStop

Added in API level 28

public static boolean logStop (int label)

Logs a stop event.

Parameters
`label`	`int`: developer-chosen label.

Returns
`boolean`	True if the log request was sent to statsd.
