KEY_TCP_PACKET_FAIL_RATE

Added in API level 30
static val KEY_TCP_PACKET_FAIL_RATE: String

This key represents the fail rate of TCP packets when the suspected data stall was detected.

This key will be included if the data stall detection method is DETECTION_METHOD_TCP_METRICS.

This value is an int percentage between 0 and 100.

Value: "tcpPacketFailRate"

Public constructors

DataStallReport

Added in API level 30
DataStallReport(
    network: Network, 
    reportTimestamp: Long, 
    detectionMethod: Int, 
    linkProperties: LinkProperties, 
    networkCapabilities: NetworkCapabilities, 
    stallDetails: PersistableBundle)

Constructor for DataStallReport.

Apps should obtain instances through android.net.ConnectivityDiagnosticsManager.ConnectivityDiagnosticsCallback#onDataStallSuspected instead of instantiating their own instances (unless for testing purposes).

Parameters
network Network: The Network for which this DataStallReport applies This value cannot be null.
reportTimestamp Long: The timestamp for the report
detectionMethod Int: The detection method used to identify this data stall Value is android.net.ConnectivityDiagnosticsManager.DataStallReport#DETECTION_METHOD_DNS_EVENTS, or android.net.ConnectivityDiagnosticsManager.DataStallReport#DETECTION_METHOD_TCP_METRICS
linkProperties LinkProperties: The LinkProperties available on network at reportTimestamp This value cannot be null.
networkCapabilities NetworkCapabilities: The NetworkCapabilities available on network at reportTimestamp This value cannot be null.
stallDetails PersistableBundle: A PersistableBundle that may contain additional info about the report This value cannot be null.

Public methods

describeContents

Added in API level 30
fun describeContents(): Int

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), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Return
Int a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either 0 or android.os.Parcelable#CONTENTS_FILE_DESCRIPTOR

equals

Added in API level 30
fun equals(other: Any?): Boolean

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 the reference object with which to compare.
o This value may be null.
Return
Boolean true if this object is the same as the obj argument; false otherwise.
