Public Methods

public abstract PendingResult<TurnBasedMultiplayer.InitiateMatchResult> acceptInvitation (GoogleApiClient apiClient, String invitationId)

Accept an invitation for a turn-based match. This changes the current player's participant status to STATUS_JOINED.

After this call returns successfully, it will be the calling player's turn in the match. At this point, the player may take their first turn by calling takeTurn(GoogleApiClient, String, byte[], String).

Required API: API
Required Scopes: SCOPE_GAMES

Parameters

apiClient	The GoogleApiClient to service the call.
invitationId	The ID of the invitation to be accepted.

Returns

• PendingResult to access the data when available.

public abstract PendingResult<TurnBasedMultiplayer.CancelMatchResult> cancelMatch (GoogleApiClient apiClient, String matchId)

Cancels a turn-based match. Once this call succeeds, the match will be removed from local storage. Note that this will cancel the match completely, forcing it to end for all players involved. See leaveMatch(GoogleApiClient, String) for a different alternative.

Required API: API
Required Scopes: SCOPE_GAMES

Parameters

apiClient	The GoogleApiClient to service the call.
matchId	The ID of the match to cancel.

Returns

• PendingResult to access the data when available.

public abstract PendingResult<TurnBasedMultiplayer.InitiateMatchResult> createMatch (GoogleApiClient apiClient, TurnBasedMatchConfig config)

Create a new turn-based match for the current game. If the provided TurnBasedMatchConfig includes automatch parameters, the server will attempt to find any previously created matches that satisfy these parameters and join the current player into the previous match. If no suitable match can be found, a new match will be created.

After this call returns successfully, it will be the calling player's turn in the new match. At this point, the player may take their first turn by calling takeTurn(GoogleApiClient, String, byte[], String).

Required API: API
Required Scopes: SCOPE_GAMES

Parameters

apiClient	The GoogleApiClient to service the call.
config	The configuration parameters for the match to create.

Returns

• PendingResult to access the data when available.

public abstract void declineInvitation (GoogleApiClient apiClient, String invitationId)

Decline an invitation for a turn-based match.

Note that this will cancel the match for the other participants and remove the match from the caller's local device.

Required API: API
Required Scopes: SCOPE_GAMES

Parameters

apiClient	The GoogleApiClient to service the call.
invitationId	The ID of the invitation to decline.

public abstract void dismissInvitation (GoogleApiClient apiClient, String invitationId)

Dismiss an invitation to a turn-based match. Dismissing an invitation will not change the state of the match for the other participants.

Required Scopes: SCOPE_GAMES

Parameters

apiClient	The GoogleApiClient to service the call.
matchId	The ID of the match to dismiss.

public abstract PendingResult<TurnBasedMultiplayer.UpdateMatchResult> finishMatch (GoogleApiClient apiClient, String matchId)

Indicate that a participant is finished with a match. This will not change the data of the match, but it will transition the match into state MATCH_STATUS_COMPLETE if the match is not already in that state. This method is most commonly used to report that a participant has finished any post-processing steps the game might have and has seen their results in the match.

Required API: API
Required Scopes: SCOPE_GAMES

Parameters

apiClient	The GoogleApiClient to service the call.
matchId	ID of the match to finish.

Returns

• PendingResult to access the data when available.

public abstract PendingResult<TurnBasedMultiplayer.UpdateMatchResult> finishMatch (GoogleApiClient apiClient, String matchId, byte[] matchData, ParticipantResult... results)

Mark a match as finished. This should be called when the match is over and all participants have results to be reported (if appropriate). Note that the last client to update a match is responsible for calling finish on that match.

On the last turn of the match, the client should call this method instead of takeTurn(GoogleApiClient, String, byte[], String).

Required API: API
Required Scopes: SCOPE_GAMES

See takeTurn(GoogleApiClient, String, byte[], String)

Parameters

apiClient	The GoogleApiClient to service the call.
matchId	ID of the match to finish.
matchData	Data representing the new state of the match after this update. Limited to a maximum of getMaxMatchDataSize(GoogleApiClient) bytes.

public abstract Intent getInboxIntent (GoogleApiClient apiClient)

Returns an intent that will let the user see and manage any outstanding invitations and matches. Note that this must be invoked using startActivityForResult(Intent, int) so that the identity of the calling package can be established.

If the user canceled the result will be RESULT_CANCELED. If the user selected an invitation or a match to accept, the result will be RESULT_OK and the data intent will contain the selected invitation/match as a parcelable extra in the extras. Based on the type of the match, the result will include either EXTRA_TURN_BASED_MATCH or EXTRA_INVITATION.

Required API: API
Required Scopes: SCOPE_GAMES

Parameters

apiClient	The GoogleApiClient to service the call.

Returns

• An Intent that can be started to view the match inbox.

public abstract int getMaxMatchDataSize (GoogleApiClient apiClient)

Parameters

apiClient	The GoogleApiClient to service the call.

Returns

• The maximum data size per match in bytes.

public abstract Intent getSelectOpponentsIntent (GoogleApiClient apiClient, int minPlayers, int maxPlayers, boolean allowAutomatch)

Returns an intent that will let the user select opponents to send an invitation to for a turn based multiplayer match. Note that this must be invoked with startActivityForResult(Intent, int), so that the identity of the calling package can be established.

The number of players passed in should be the desired number of additional players to select, not including the current player. So, for a game that can handle between 2 and 4 players, minPlayers would be 1 and maxPlayers would be 3.

Players may be preselected by specifying a list of player IDs in the EXTRA_PLAYER_IDS extra on the returned intent.

If the user canceled, the result will be RESULT_CANCELED. If the user selected players, the result will be RESULT_OK, and the data intent will contain the selected player IDs in EXTRA_PLAYER_IDS and the minimum and maximum numbers of additional auto-match players in EXTRA_MIN_AUTOMATCH_PLAYERS and EXTRA_MAX_AUTOMATCH_PLAYERS respectively. The player IDs in EXTRA_PLAYER_IDS will include only the other players selected, not the current player.

If the allowAutomatch parameter is set to false, the UI will not display an option for selecting automatch players. Set this to false if your game does not support automatching.

Required API: API
Required Scopes: SCOPE_GAMES

See createMatch(GoogleApiClient, TurnBasedMatchConfig)

Parameters

apiClient	The GoogleApiClient to service the call.
minPlayers	The minimum number of players to select (not including the current player).

Note that only one match update listener may be active at a time. Calling this method while another match update listener was previously registered will replace the original listener with the new one.

Required API: API
Required Scopes: SCOPE_GAMES

Parameters

apiClient	The GoogleApiClient to service the call.
listener	The listener that is called when a match update is received. The listener is called on the main thread.

public abstract PendingResult<TurnBasedMultiplayer.InitiateMatchResult> rematch (GoogleApiClient apiClient, String matchId)

Create a rematch of a previously completed turn-based match. The new match will have the same participants as the previous match. Note that only one rematch may be created from any single completed match, and only by a player that has already called Finish on the match. It is only valid to call this if canRematch() return true - calling this method any other time will result in an error.

After this call returns successfully, it will be the calling player's turn in the new match. At this point, the player may take their first turn by calling takeTurn(GoogleApiClient, String, byte[], String).

Required API: API
Required Scopes: SCOPE_GAMES

Parameters

matchId	The ID of the previous match to re-create.

Returns

• PendingResult to access the data when available.

public abstract PendingResult<TurnBasedMultiplayer.UpdateMatchResult> takeTurn (GoogleApiClient apiClient, String matchId, byte[] matchData, String pendingParticipantId, ParticipantResult... results)

Update a match with new turn data. The participant that is passed in as the pending participant will be notified that it is their turn to take action. If no pending participant is provided and the match has available auto-match slots, the match will wait for additional players to be found. If there are no auto-match slots available for this match, a pending participant ID is required.

Note that players will not receive invitations for matches until this method is called. An invitation will be sent to a player the first time they are set as the pending participant of a match.

For the final turn of the match, there is no need to call this method. Instead, call finishMatch(GoogleApiClient, String) directly.

Required API: API
