GameManager

Kotlin |Java

public final class GameManager
extends Object

java.lang.Object
↳	android.app.GameManager

The GameManager allows system apps to modify and query the game mode of apps.

Note: After Build.VERSION_CODES.VANILLA_ICE_CREAM, some devices that do not support the GameManager features may not publish a GameManager instance. These device types include:

Wear devices (PackageManager.FEATURE_WATCH)

Therefore, you should always do a null check on the return value of Context.getSystemService(Class) and Context.getSystemService(String) when trying to obtain an instance of GameManager on the aforementioned device types.

Inherited methods

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

Constants

GAME_MODE_BATTERY

Added in API level 31

public static final int GAME_MODE_BATTERY

Battery game mode will save battery and give longer game play time.

Constant Value: 3 (0x00000003)

GAME_MODE_CUSTOM

Added in API level 34

public static final int GAME_MODE_CUSTOM

Custom game mode that has user-provided configuration overrides.

Custom game mode is expected to be handled only by the platform using users' preferred config. It is currently not allowed to opt in custom mode in game mode XML file nor expected to perform app-based optimizations when activated.

Constant Value: 4 (0x00000004)

GAME_MODE_PERFORMANCE

Added in API level 31

public static final int GAME_MODE_PERFORMANCE

Performance game mode maximizes the game's performance.

This game mode is highly likely to increase battery consumption.

Constant Value: 2 (0x00000002)

GAME_MODE_STANDARD

Added in API level 31

public static final int GAME_MODE_STANDARD

Standard game mode means the platform will use the game's default performance characteristics.

Constant Value: 1 (0x00000001)

GAME_MODE_UNSUPPORTED

Added in API level 31

public static final int GAME_MODE_UNSUPPORTED

Game mode is not supported for this application.

Constant Value: 0 (0x00000000)

Public methods

getGameMode

Added in API level 31

public int getGameMode ()

Return the user selected game mode for this application.

An application can use android:isGame="true" or android:appCategory="game" to indicate that the application is a game. If an application is not a game, always return GAME_MODE_UNSUPPORTED.

Developers should call this API every time the application is resumed.

If a game's targetSdkVersion is Build.VERSION_CODES.TIRAMISU or lower, and when the game mode is set to GAME_MODE_CUSTOM which is available in Build.VERSION_CODES.UPSIDE_DOWN_CAKE or newer, this API will return GAME_MODE_STANDARD instead for backward compatibility.

Returns
`int`	Value is `GAME_MODE_UNSUPPORTED`, `GAME_MODE_STANDARD`, `GAME_MODE_PERFORMANCE`, `GAME_MODE_BATTERY`, or `GAME_MODE_CUSTOM`

setGameState

Added in API level 33

public void setGameState (GameState gameState)

Called by games to communicate the current state to the platform.

Parameters
`gameState`	`GameState`: An object set to the current state. This value cannot be `null`.
