## Constants
### PASSIVE_INTERVAL
Added in[API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public static final int PASSIVE_INTERVAL
```
Represents a passive only request. Such a request will not trigger any active GNSS measurements or power usage itself, but may receive GNSS measurements generated in response to other requests.
Note that on Android T, such a request will trigger one GNSS measurement. Another GNSS measurement will be triggered after[PASSIVE_INTERVAL](https://developer.android.com/reference/android/location/GnssMeasurementRequest#PASSIVE_INTERVAL)and so on.
**See also:**
- [getIntervalMillis()](https://developer.android.com/reference/android/location/GnssMeasurementRequest#getIntervalMillis())
Constant Value: 2147483647 (0x7fffffff)
## Fields
### CREATOR
Added in[API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public static final Creator CREATOR
```
## Public methods
### describeContents
Added in[API level 31](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[writeToParcel(android.os.Parcel, int)](https://developer.android.com/reference/android/os/Parcelable#writeToParcel(android.os.Parcel,%20int)), the return value of this method must include the[CONTENTS_FILE_DESCRIPTOR](https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR)bit.
| Returns ||
|-------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `int` | a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either`0`or[CONTENTS_FILE_DESCRIPTOR](https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR)
|
### equals
Added in[API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public boolean equals (Object obj)
```
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.
| Parameters ||
|-------|--------------------------------------------------------------|
| `obj` | `Object`: the reference object with which to compare.
|
| Returns ||
|-----------|-------------------------------------------------------------------------------|
| `boolean` | `true`if this object is the same as the obj argument;`false`otherwise.
|
### getIntervalMillis
Added in[API level 33](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public int getIntervalMillis ()
```
Returns the requested time interval between the reported measurements in milliseconds, or[PASSIVE_INTERVAL](https://developer.android.com/reference/android/location/GnssMeasurementRequest#PASSIVE_INTERVAL)if this is a passive, no power request. A passive request will not actively generate GNSS measurement updates, but may receive GNSS measurement updates generated as a result of other GNSS measurement requests.
If the time interval is not set, the default value is 0, which means the fastest rate the GNSS chipset can report.
The GNSS chipset may report measurements with a rate faster than requested.
Note that on Android T, a request interval of[PASSIVE_INTERVAL](https://developer.android.com/reference/android/location/GnssMeasurementRequest#PASSIVE_INTERVAL)will first trigger one GNSS measurement. Another GNSS measurement will be triggered after[PASSIVE_INTERVAL](https://developer.android.com/reference/android/location/GnssMeasurementRequest#PASSIVE_INTERVAL)milliseconds ans so on.
| Returns ||
|-------|------------------------------|
| `int` | Value is 0 or greater
|
### hashCode
Added in[API level 31](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[HashMap](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[equals](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[equals](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.
| Returns ||
|-------|-------------------------------------------|
| `int` | a hash code value for this object.
|
### isFullTracking
Added in[API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public boolean isFullTracking ()
```
Represents whether to enable full GNSS tracking.
If true, GNSS chipset switches off duty cycling. In such a mode, no clock discontinuities are expected, and when supported, carrier phase should be continuous in good signal conditions. All non-blocklisted, healthy constellations, satellites and frequency bands that are meaningful to positioning accuracy must be tracked and reported in this mode. The GNSS chipset will consume more power in full tracking mode than in duty cycling mode. If false, GNSS chipset optimizes power via duty cycling, constellations and frequency limits, etc.
Full GNSS tracking mode affects GnssMeasurement and other GNSS functionalities including GNSS location.
| Returns ||
|-----------|--------|
| `boolean` |
|
### toString
Added in[API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public String toString ()
```
Returns a string representation of the object.
| Returns ||
|--------------------------------------------------------------------|------------------------------------|
| [String](https://developer.android.com/reference/java/lang/String) | This value cannot be`null`.
|
### writeToParcel
Added in[API level 31](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.
| Parameters ||
|----------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `parcel` | `Parcel`: This value cannot be`null`.
|
| `flags` | `int`: Additional flags about how the object should be written. May be 0 or[Parcelable.PARCELABLE_WRITE_RETURN_VALUE](https://developer.android.com/reference/android/os/Parcelable#PARCELABLE_WRITE_RETURN_VALUE). Value is either`0`or a combination of[Parcelable.PARCELABLE_WRITE_RETURN_VALUE](https://developer.android.com/reference/android/os/Parcelable#PARCELABLE_WRITE_RETURN_VALUE), and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
