Public methods

describeContents

Added in API level 29
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

equals

Added in API level 29
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.
Return
Boolean true if this object is the same as the obj argument; false otherwise.

getAsuLevel

Added in API level 29
fun getAsuLevel(): Int

Get the RSRP in ASU. Asu is calculated based on 3GPP RSRP. Refer to 3GPP 27.007 (Ver 10.3.0) Sec 8.69

Int RSRP in ASU 0..97, 255, or UNAVAILABLE

getCsiCqiReport

Added in API level 31
fun getCsiCqiReport(): MutableList<Int!>

Return a list of CSI channel quality indicators (CQI) for all subbands. If the CQI report is for the entire wideband, a single CQI index is provided. If the CQI report is for all subbands, one CQI index is provided for each subband, in ascending order of subband index. If CQI is not available, the CQI report is empty. Reference: 3GPP TS 138.214 section 5.2.2.1.

Return
MutableList<Int!> the CQIs for all subbands if available or empty list if unavailable.
This value cannot be null.
Value is between 0 and 15 inclusive

getCsiCqiTableIndex

Added in API level 31
fun getCsiCqiTableIndex(): Int

Return CSI channel quality indicator (CQI) table index. There are multiple CQI tables. The definition of CQI in each table is different. Reference: 3GPP TS 138.214 section 5.2.2.1.

Return
Int the CQI table index if available or UNAVAILABLE if unavailable.
Value is between 1 and 3 inclusive

getCsiRsrp

Added in API level 29
fun getCsiRsrp(): Int

Reference: 3GPP TS 38.133 10.1.6.1. Range: -156 dBm to -31 dBm.

Return
Int CSI reference signal received power, CellInfo.UNAVAILABLE means unreported value.

getCsiRsrq

Added in API level 29
fun getCsiRsrq(): Int

Reference: 3GPP TS 38.215. Range: -20 dB to -3 dB.

Return
Int CSI reference signal received quality, CellInfo.UNAVAILABLE means unreported value.

Return
Int CSI signal-to-noise and interference ratio, CellInfo.UNAVAILABLE means unreported value.

getDbm

getLevel

Added in API level 29
fun getLevel(): Int

Retrieve an abstract level value for the overall signal quality.

Return
Int Value is between android.telephony.CellSignalStrength#SIGNAL_STRENGTH_NONE_OR_UNKNOWN and android.telephony.CellSignalStrength#SIGNAL_STRENGTH_GREAT inclusive

getSsRsrp

Added in API level 29
fun getSsRsrp(): Int

Reference: 3GPP TS 38.133 10.1.6.1. Range: -156 dBm to -31 dBm.

Return
Int SS reference signal received power, CellInfo.UNAVAILABLE means unreported value.

getSsRsrq

Added in API level 29
fun getSsRsrq(): Int

Reference: 3GPP TS 38.215; 3GPP TS 38.133 section 10 Range: -43 dB to 20 dB.

Return
Int SS reference signal received quality, CellInfo.UNAVAILABLE means unreported value.

getSsSinr

Added in API level 29

Return
Int SS signal-to-noise and interference ratio, CellInfo.UNAVAILABLE means unreported value.

getTimingAdvanceMicros

Added in API level 34
fun getTimingAdvanceMicros(): Int

Get the timing advance value for a one way trip from cell to device for NR in microseconds. android.telephony.CellInfo#UNAVAILABLE is reported when there is no active RRC connection. Reference: 3GPP TS 36.213 section 4.2.3. Range: 0 us to 1282 us.

Return
Int the NR timing advance if available or android.telephony.CellInfo#UNAVAILABLE if unavailable.
Value is between 0 and 1282 inclusive

hashCode

Added in API level 29
fun hashCode(): Int

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by 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 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 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.
Return
Int a hash code value for this object.

toString

Added in API level 29
fun toString(): String

Returns a string representation of the object.

Return
String a string representation of the object.

writeToParcel

Added in API level 29
fun writeToParcel(
    dest: Parcel,
    flags: Int
): Unit
Parameters
dest Parcel: The Parcel in which the object should be written.
This value cannot be null.
flags Int: Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE.
Value is either 0 or a combination of the following:
