Class AmplitudeClient

java.lang.Object

com.amplitude.api.AmplitudeClient

Direct Known Subclasses:

PinnedAmplitudeClient

public class AmplitudeClient
extends java.lang.Object

AmplitudeClient

This is the SDK instance class that contains all of the SDK functionality.

Note: call the methods on the default shared instance in the Amplitude class, for example: Amplitude.getInstance().logEvent();

Many of the SDK functions return the SDK instance back, allowing you to chain multiple method calls together, for example: Amplitude.getInstance().initialize(this, "APIKEY").enableForegroundTracking(getApplication())
