Capacitor Android API

Capacitor Android is the native runtime that powers Capacitor apps on Android.


The Android bridge is the heart of the Capacitor Android library. There are several methods available on the bridge which provide information or change behavior.

When registered with Capacitor, plugins have access to the bridge:



public CapConfig getConfig()

This property contains the configuration object known to the Capacitor runtime.


public void triggerJSEvent(final String eventName, final String target)
public void triggerJSEvent(final String eventName, final String target, final String data)

Fire an event on a JavaScript EventTarget such as window or document. If possible, it is preferred to use Plugin Events instead.


bridge.triggerJSEvent("myCustomEvent", "window");
bridge.triggerJSEvent("myCustomEvent", "document", "{ 'dataKey': 'dataValue' }");

Note: data must be a serialized JSON string value.

Passing data

Notes on how to work with data that is passed between environments can be found here.
