↳	android.bluetooth.BluetoothGattService

Represents a Bluetooth GATT Service

Gatt Service contains a collection of BluetoothGattCharacteristic, as well as referenced services.

Summary

Constants
`int`	`SERVICE_TYPE_PRIMARY` Primary service
`int`	`SERVICE_TYPE_SECONDARY` Secondary service (included by primary services)

Inherited constants

From interface android.os.Parcelable

`int`	`CONTENTS_FILE_DESCRIPTOR` Descriptor bit used with `describeContents()`: indicates that the Parcelable object's flattened representation includes a file descriptor.
`int`	`PARCELABLE_WRITE_RETURN_VALUE` Flag for use with `writeToParcel(Parcel, int)`: the object being written is a return value, that is the result of a function such as "`Parcelable someFunction()`", "`void someFunction(out Parcelable)`", or "`void someFunction(inout Parcelable)`".

Fields
`public static final Creator<BluetoothGattService>`	`CREATOR`
`protected List<BluetoothGattCharacteristic>`	`mCharacteristics` List of characteristics included in this service.
`protected List<BluetoothGattService>`	`mIncludedServices` List of included services for this service.

Public constructors
`BluetoothGattService(UUID uuid, int serviceType)` Create a new BluetoothGattService.

Public methods
`boolean`	`addCharacteristic(BluetoothGattCharacteristic characteristic)` Add a characteristic to this service.
`boolean`	`addService(BluetoothGattService service)` Add an included service to this service.
`BluetoothGattCharacteristic`	`getCharacteristic(UUID uuid)` Returns a characteristic with a given UUID out of the list of characteristics offered by this service.
`List<BluetoothGattCharacteristic>`	`getCharacteristics()` Returns a list of characteristics included in this service.
`List<BluetoothGattService>`	`getIncludedServices()` Get the list of included GATT services for this service.
`int`	`getInstanceId()` Returns the instance ID for this service If a remote device offers multiple services with the same UUID (ex.
`int`	`getType()` Get the type of this service (primary/secondary)
`UUID`	`getUuid()` Returns the UUID of this service
`void`	`writeToParcel(Parcel out, int flags)` Flatten this object in to a Parcel.

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 timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

From interface


        
          android.os.Parcelable

`abstract int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`abstract void`	`writeToParcel(Parcel dest, int flags)` Flatten this object in to a Parcel.

Constants

SERVICE_TYPE_PRIMARY

public static final int SERVICE_TYPE_PRIMARY

Primary service

Constant Value: 0 (0x00000000)

SERVICE_TYPE_SECONDARY

public static final int SERVICE_TYPE_SECONDARY

Secondary service (included by primary services)

Constant Value: 1 (0x00000001)

Fields

CREATOR

public static final Creator<BluetoothGattService> CREATOR

mCharacteristics

protected List<BluetoothGattCharacteristic> mCharacteristics

List of characteristics included in this service.

mIncludedServices

protected List<BluetoothGattService> mIncludedServices

List of included services for this service.

Public constructors

BluetoothGattService

public BluetoothGattService (UUID uuid, 
                int serviceType)

Create a new BluetoothGattService.

Requires Manifest.permission.BLUETOOTH permission.

Parameters
`uuid`	`UUID`: The UUID for this service
`serviceType`	`int`: The type of this service, `BluetoothGattService#SERVICE_TYPE_PRIMARY` or `BluetoothGattService#SERVICE_TYPE_SECONDARY`

Public methods

addCharacteristic

public boolean addCharacteristic (BluetoothGattCharacteristic characteristic)

Add a characteristic to this service.

Requires Manifest.permission.BLUETOOTH permission.

Parameters
`characteristic`	`BluetoothGattCharacteristic`: The characteristics to be added

Returns
`boolean`	true, if the characteristic was added to the service

addService

public boolean addService (BluetoothGattService service)

Add an included service to this service.

Requires Manifest.permission.BLUETOOTH permission.

Parameters
`service`	`BluetoothGattService`: The service to be added

Returns
`boolean`	true, if the included service was added to the service

getCharacteristic

public BluetoothGattCharacteristic getCharacteristic (UUID uuid)

Returns a characteristic with a given UUID out of the list of characteristics offered by this service.

This is a convenience function to allow access to a given characteristic without enumerating over the list returned by getCharacteristics() manually.

If a remote service offers multiple characteristics with the same UUID, the first instance of a characteristic with the given UUID is returned.

Parameters
`uuid`	`UUID`

Returns
`BluetoothGattCharacteristic`	GATT characteristic object or null if no characteristic with the given UUID was found.

getCharacteristics

public List<BluetoothGattCharacteristic> getCharacteristics ()

Returns a list of characteristics included in this service.

Returns
`List<BluetoothGattCharacteristic>`	Characteristics included in this service

getIncludedServices

public List<BluetoothGattService> getIncludedServices ()

Get the list of included GATT services for this service.

Returns
`List<BluetoothGattService>`	List of included services or empty list if no included services were discovered.

getInstanceId

public int getInstanceId ()

Returns the instance ID for this service

If a remote device offers multiple services with the same UUID (ex. multiple battery services for different batteries), the instance ID is used to distuinguish services.

Returns
`int`	Instance ID of this service

getType

public int getType ()

Get the type of this service (primary/secondary)

Returns
`int`

getUuid

public UUID getUuid ()

Returns the UUID of this service

Returns
`UUID`	UUID of this service

writeToParcel

public void writeToParcel (Parcel out, 
                int flags)

Flatten this object in to a Parcel.

Parameters
`out`	`Parcel`: The Parcel in which the object should be written.
`flags`	`int`: Additional flags about how the object should be written. May be 0 or `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
