Methods

`IntentLauncher.getApplicationIconAsync(packageName)`

Parameter	Type	Description
packageName	`string`	The package name of the target application. For example, `com.google.android.gm` for Gmail.

Returns:

Promise<string>

A promise that resolves to the base64-encoded PNG icon of the specified application, or an empty string if the icon could not be retrieved.

`IntentLauncher.openApplication(packageName)`

Parameter	Type	Description
packageName	`string`	For example: `com.google.android.gm` for Gmail.

Opens an application by its package name.

Returns:

void

`IntentLauncher.startActivityAsync(activityAction, params)`

Parameter	Type	Description
activityAction	`string`	The action to be performed, for example, `IntentLauncher.ActivityAction.WIRELESS_SETTINGS`. There are a few pre-defined constants you can use for this parameter. You can find them at `expo-intent-launcher/src/IntentLauncher.ts`.
params(optional)	`IntentLauncherParams`	An object of intent parameters. Default:`{}`

Starts the specified activity. The method will return a promise which resolves when the user returns to the app.

Returns:

Promise<IntentLauncherResult>

A promise which fulfils with IntentLauncherResult object.

Interfaces

`IntentLauncherParams`

Property	Type	Description
category(optional)	`string`	Category provides more details about the action the intent performs. See `Intent.addCategory`.
className(optional)	`string`	Class name of the ComponentName.
data(optional)	`string`	A URI specifying the data that the intent should operate upon. (Note: Android requires the URI scheme to be lowercase, unlike the formal RFC.)
extra(optional)	`Record<string, any>`	A map specifying additional key-value pairs which are passed with the intent as `extras`. The keys must include a package prefix, for example the app `com.android.contacts` would use names like `com.android.contacts.ShowAll`.
flags(optional)	`number`	Bitmask of flags to be used. See `Intent.setFlags` for more details.
packageName(optional)	`string`	Package name used as an identifier of ComponentName. Set this only if you want to explicitly set the component to handle the intent.
type(optional)	`string`	A string specifying the MIME type of the data represented by the data parameter. Ignore this argument to allow Android to infer the correct MIME type.

`IntentLauncherResult`

Property	Type	Description
data(optional)	`string`	Optional data URI that can be returned by the activity.
extra(optional)	`object`	Optional extras object that can be returned by the activity.
resultCode	`ResultCode`	Result code returned by the activity.
