Public methods

bindCustomTabsService

public static boolean bindCustomTabsService (Context context, 
                String packageName, 
                CustomTabsServiceConnection connection)

Bind to a CustomTabsService using the given package name and ServiceConnection.

Parameters
`context`	`Context`: `Context` to use while calling `Context.bindService(Intent, ServiceConnection, int)`
`packageName`	`String`: Package name to set on the `Intent` for binding.
`connection`	`CustomTabsServiceConnection`: `CustomTabsServiceConnection` to use when binding. This will return a `CustomTabsClient` on `#onCustomTabsServiceConnected(ComponentName, CustomTabsClient)`

Returns
`boolean`	Whether the binding was successful.

bindCustomTabsServicePreservePriority

public static boolean bindCustomTabsServicePreservePriority (Context context, 
                String packageName, 
                CustomTabsServiceConnection connection)

Bind to a CustomTabsService using the given package name and ServiceConnection. This is similar to bindCustomTabsService(Context, String, CustomTabsServiceConnection) but does not use Context.BIND_WAIVE_PRIORITY, making it suitable for use cases where the browser is immediately going to be launched and breaking the connection would be unrecoverable.

Parameters
`context`	`Context`: `Context` to use while calling `Context.bindService(Intent, ServiceConnection, int)`
`packageName`	`String`: Package name to set on the `Intent` for binding.
`connection`	`CustomTabsServiceConnection`: `CustomTabsServiceConnection` to use when binding. This will return a `CustomTabsClient` on `#onCustomTabsServiceConnected(ComponentName, CustomTabsClient)`

Returns
`boolean`	Whether the binding was successful.

connectAndInitialize

public static boolean connectAndInitialize (Context context, 
                String packageName)

Connects to the Custom Tabs warmup service, and initializes the browser. This convenience method connects to the service, and immediately warms up the Custom Tabs implementation. Since service connection is asynchronous, the return code is not the return code of warmup. This call is optional, and clients are encouraged to connect to the service, call warmup() and create a session. In this case, calling this method is not necessary.

Parameters
`context`	`Context`: `Context` to use to connect to the remote service.
`packageName`	`String`: Package name of the target implementation.

Returns
`boolean`	Whether the binding was successful.

extraCommand

public Bundle extraCommand (String commandName, 
                Bundle args)

Can be used as a channel between the Custom Tabs client and the provider to do something that is not part of the API yet.

Parameters
`commandName`	`String`
`args`	`Bundle`

Returns
`Bundle`

getPackageName

public static String getPackageName (Context context, 
                List<String> packages)

Returns the preferred package to use for Custom Tabs, preferring the default VIEW handler.

Parameters
`context`	`Context`
`packages`	`List`

Returns
`String`

getPackageName

public static String getPackageName (Context context, 
                List<String> packages, 
                boolean ignoreDefault)

Returns the preferred package to use for Custom Tabs. The preferred package name is the default VIEW intent handler as long as it supports Custom Tabs. To modify this preferred behavior, set ignoreDefault to true and give a non empty list of package names in packages. This method queries the PackageManager to determine which packages support the Custom Tabs API. On apps that target Android 11 and above, this requires adding the following package visibility elements to your manifest.

 <!-- Place inside the <queries> element. -->
 <intent>
   <action android:name="android.support.customtabs.action.CustomTabsService" />
 </intent>

Parameters
`context`	`Context`: `Context` to use for querying the packages.
`packages`	`List`: Ordered list of packages to test for Custom Tabs support, in decreasing order of priority.
`ignoreDefault`	`boolean`: If set, the default VIEW handler won't get priority over other browsers.

Returns
`String`	The preferred package name for handling Custom Tabs, or `null`.

newSession

public CustomTabsSession newSession (CustomTabsCallback callback)

Creates a new session through an ICustomTabsService with the optional callback. This session can be used to associate any related communication through the service with an intent and then later with a Custom Tab. The client can then send later service calls or intents to through same session-intent-Custom Tab association.

Parameters
`callback`	`CustomTabsCallback`: The callback through which the client will receive updates about the created session. Can be null. All the callbacks will be received on the UI thread.

Returns
`CustomTabsSession`	The session object that was created as a result of the transaction. The client can use this to relay session specific calls. Null if the service failed to respond (threw a RemoteException).

newSession

public CustomTabsSession newSession (CustomTabsCallback callback, 
                int id)

Creates a new session or updates a callback for the existing session through an ICustomTabsService. This session can be used to associate any related communication through the service with an intent and then later with a Custom Tab. The client can then send later service calls or intents to through same session-intent-Custom Tab association.

Parameters
`callback`	`CustomTabsCallback`: The callback through which the client will receive updates about the created session. Can be null. All the callbacks will be received on the UI thread.
`id`	`int`: The session id. If the session with the specified id already exists for the given client application, the new callback is supplied to that session and further attempts to launch URLs using that session will update the existing Custom Tab instead of launching a new one.

Returns
`CustomTabsSession`	The session object that was created as a result of the transaction. The client can use this to relay session specific calls. Null if the service failed to respond (threw a RemoteException). If `null` is returned, attempt using `newSession(CustomTabsCallback)` which is supported with older browsers.

warmup

public boolean warmup (long flags)

Warm up the browser process. Allows the browser application to pre-initialize itself in the background. Significantly speeds up URL opening in the browser. This is asynchronous and can be called several times.

Parameters
`flags`	`long`: Reserved for future use.

Returns
`boolean`	Whether the warmup was successful.
