<br />

*** ** * ** ***

A class that contains information about a GNSS antenna. GNSS antenna characteristics can change
with device configuration, such as when a device is folded open or closed. Antenna information is
delivered to registered instances of `https://developer.android.com/reference/android/location/GnssAntennaInfo.Listener`.

Antenna info parameters are measured for each specific device model by the device
manufacturers and provided to the Android framework.

`https://developer.android.com/reference/android/location/GnssAntennaInfo` is returned per frequency band at the center frequency of the band.

## Fields

### CREATOR

Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public static final Creator<GnssAntennaInfo> CREATOR
```

<br />

<br />

## Public methods

### describeContents

Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int describeContents ()
```

Describe the kinds of special objects contained in this Parcelable
instance's marshaled representation. For example, if the object will
include a file descriptor in the output of `https://developer.android.com/reference/android/os/Parcelable#writeToParcel(android.os.Parcel,%20int)`,
the return value of this method must include the
`https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR` bit.

<br />

| Returns ||
|---|---|
| `int` | a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or - `https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR` |

### equals

Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public boolean equals (Object o)
```

Indicates whether some other object is "equal to" this one.


The `equals` method implements an equivalence relation
on non-null object references:

- It is *reflexive*: for any non-null reference value `x`, `x.equals(x)` should return `true`.
- It is *symmetric*: for any non-null reference values `x` and `y`, `x.equals(y)` should return `true` if and only if `y.equals(x)` returns `true`.
- It is *transitive*: for any non-null reference values `x`, `y`, and `z`, if `x.equals(y)` returns `true` and `y.equals(z)` returns `true`, then `x.equals(z)` should return `true`.
- It is *consistent*: for any non-null reference values `x` and `y`, multiple invocations of `x.equals(y)` consistently return `true` or consistently return `false`, provided no information used in `equals` comparisons on the objects is modified.
- For any non-null reference value `x`, `x.equals(null)` should return `false`.


An equivalence relation partitions the elements it operates on
into *equivalence classes*; all the members of an
equivalence class are equal to each other. Members of an
equivalence class are substitutable for each other, at least
for some purposes.

<br />

| Parameters ||
|---|---|
| `o` | `Object`: the reference object with which to compare. <br /> |

| Returns ||
|---|---|
| `boolean` | `true` if this object is the same as the obj argument; `false` otherwise. <br /> |

### getCarrierFrequencyMHz

Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public double getCarrierFrequencyMHz ()
```

Returns the center frequency of the corresponding carrier frequency band.

<br />

| Returns ||
|---|---|
| `double` | Value is 0.0f or greater <br /> |

### getPhaseCenterOffset

Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public GnssAntennaInfo.PhaseCenterOffset getPhaseCenterOffset ()
```

Returns a `https://developer.android.com/reference/android/location/GnssAntennaInfo.PhaseCenterOffset` object encapsulating the phase center offset and
corresponding uncertainties in millimeters.

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/android/location/GnssAntennaInfo.PhaseCenterOffset` | `https://developer.android.com/reference/android/location/GnssAntennaInfo.PhaseCenterOffset` This value cannot be `null`. <br /> |

### getPhaseCenterVariationCorrections

Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public GnssAntennaInfo.SphericalCorrections getPhaseCenterVariationCorrections ()
```

Returns a `https://developer.android.com/reference/android/location/GnssAntennaInfo.SphericalCorrections` object encapsulating the phase center variation
corrections and corresponding uncertainties in millimeters.

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/android/location/GnssAntennaInfo.SphericalCorrections` | phase center variation corrections as `https://developer.android.com/reference/android/location/GnssAntennaInfo.SphericalCorrections` This value may be `null`. <br /> |

### getSignalGainCorrections

Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public GnssAntennaInfo.SphericalCorrections getSignalGainCorrections ()
```

Returns a `https://developer.android.com/reference/android/location/GnssAntennaInfo.SphericalCorrections` object encapsulating the signal gain
corrections and corresponding uncertainties in dBi.

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/android/location/GnssAntennaInfo.SphericalCorrections` | signal gain corrections as `https://developer.android.com/reference/android/location/GnssAntennaInfo.SphericalCorrections` This value may be `null`. <br /> |

### hashCode

Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int hashCode ()
```

Returns a hash code value for the object. This method is
supported for the benefit of hash tables such as those provided by
`https://developer.android.com/reference/java/util/HashMap`.


The general contract of `hashCode` is:

- Whenever it is invoked on the same object more than once during an execution of a Java application, the `hashCode` method must consistently return the same integer, provided no information used in `equals` comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
- If two objects are equal according to the `https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object)` method, then calling the `hashCode` method on each of the two objects must produce the same integer result.
- It is *not* required that if two objects are unequal according to the `https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object)` method, then calling the `hashCode` method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

<br />

<br />

| Returns ||
|---|---|
| `int` | a hash code value for this object. <br /> |

### toString

Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public String toString ()
```

Returns a string representation of the object.

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/lang/String` | a string representation of the object. <br /> |

### writeToParcel

Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public void writeToParcel (Parcel parcel, 
                int flags)
```

Flatten this object in to a Parcel.

<br />

| Parameters ||
|---|---|
| `parcel` | `Parcel`: This value cannot be `null`. <br /> |
| `flags` | `int`: Additional flags about how the object should be written. May be 0 or `https://developer.android.com/reference/android/os/Parcelable#PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of the following: - `https://developer.android.com/reference/android/os/Parcelable#PARCELABLE_WRITE_RETURN_VALUE` |
