SignalStrength

INVALID

public static final int INVALID

Indicates the invalid measures of signal strength. For example, this can be returned by getEvdoDbm() or getCdmaDbm()

Constant Value: 2147483647 (0x7fffffff)

CREATOR

public static final Creator<SignalStrength> CREATOR

Parcelable.Creator

SignalStrength

public SignalStrength (SignalStrength s)

This constructor is used to create a copy of an existing SignalStrength object.

describeContents

public int describeContents ()

Parcelable.describeContents

equals

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.

getCdmaDbm

public int getCdmaDbm ()

This method was deprecated in API level 29.
this information should be retrieved from CellSignalStrengthCdma.getCdmaDbm.

Get the CDMA RSSI value in dBm

getCdmaEcio

public int getCdmaEcio ()

This method was deprecated in API level 29.
this information should be retrieved from CellSignalStrengthCdma.getCdmaEcio.

Get the CDMA Ec/Io value in dB*10

getCellSignalStrengths

public List<T> getCellSignalStrengths (Class<T> clazz)

Returns a List of CellSignalStrength Components of this SignalStrength Report. Use this API to access underlying CellSignalStrength objects that provide more granular information about the SignalStrength report. Only valid (non-empty) CellSignalStrengths will be returned. The order of any returned elements is not guaranteed, and the list may contain more than one instance of a CellSignalStrength type.

getCellSignalStrengths

public List<CellSignalStrength> getCellSignalStrengths ()

Returns a List of CellSignalStrength Components of this SignalStrength Report. Use this API to access underlying CellSignalStrength objects that provide more granular information about the SignalStrength report. Only valid (non-empty) CellSignalStrengths will be returned. The order of any returned elements is not guaranteed, and the list may contain more than one instance of a CellSignalStrength type.

getEvdoDbm

public int getEvdoDbm ()

This method was deprecated in API level 29.
this information should be retrieved from CellSignalStrengthCdma.getEvdoDbm.

Get the EVDO RSSI value in dBm

getEvdoEcio

public int getEvdoEcio ()

This method was deprecated in API level 29.
this information should be retrieved from CellSignalStrengthCdma.getEvdoEcio.

Get the EVDO Ec/Io value in dB*10

getEvdoSnr

public int getEvdoSnr ()

This method was deprecated in API level 29.
this information should be retrieved from CellSignalStrengthCdma.getEvdoSnr.

Get the signal to noise ratio. Valid values are 0-8. 8 is the highest.

getGsmBitErrorRate

public int getGsmBitErrorRate ()

This method was deprecated in API level 29.
this information should be retrieved from CellSignalStrengthGsm.getBitErrorRate.

Get the GSM bit error rate (0-7, 99) as defined in TS 27.007 8.5

getGsmSignalStrength

public int getGsmSignalStrength ()

This method was deprecated in API level 29.
this information should be retrieved from CellSignalStrengthGsm.getAsuLevel.

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

getLevel

public int getLevel ()

Retrieve an abstract level value for the overall signal strength.

getTimestampMillis

public long getTimestampMillis ()

Value is a non-negative timestamp in the SystemClock.elapsedRealtime() time base.

hashCode

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.

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.

isGsm

public boolean isGsm ()

This method was deprecated in API level 29.
This method returns true if there are any 3gpp type SignalStrength elements in this SignalStrength report or if the report contains no valid SignalStrength information. Instead callers should use getCellSignalStrengths() to determine which types of information are contained in the SignalStrength report.

toString

public String toString ()

Returns a string representation of the object.

writeToParcel

public void writeToParcel (Parcel out, 
                int flags)
