IntentLauncherAndroid

Provides a way to launch android intents. e.g. - opening a specific settings screen.

Starts the specified activity. The optional data parameter can be specified to pass additional data object to the activity. The method will return a promise which resolves when the user returns to the app.
There are a few pre-defined constants you can use for the activity parameter. You can find them at expo/expo-sdk/src/IntentLauncherAndroid.js.

import { IntentLauncherAndroid } from 'expo';

// Open location settings
IntentLauncherAndroid.startActivityAsync(
  IntentLauncherAndroid.ACTION_LOCATION_SOURCE_SETTINGS
);
