CREATOR

Added in API level 17
public static final Creator<CellSignalStrengthCdma> CREATOR

Implement the Parcelable interface

Public methods

describeContents

Added in API level 17
public int describeContents ()

Implement the Parcelable interface

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

equals

Added in API level 17
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.

Parameters
o Object: the reference object with which to compare.

Returns
boolean true if this object is the same as the obj argument; false otherwise.

getAsuLevel

Added in API level 17
public int getAsuLevel ()

Get the 1xRTT Level in (Android) ASU. There is no standard definition of ASU for CDMA; however, Android defines it as the the lesser of the following two results (for 1xRTT):

RSSI Range (dBm)ASU Value
-75..16
-82..-768
-90..-834
-95..-912
-100..-961
..-10199
Ec/Io Range (dB)ASU Value
-90..16
-100..-918
-115..-1014
-130..-1162
--150..-1311
..-15199

Returns
int 1xRTT Level in Android ASU {1,2,4,8,16,99}

getCdmaDbm

Added in API level 17
public int getCdmaDbm ()

Get the CDMA RSSI value in dBm

Returns
int

getCdmaEcio

Added in API level 17
public int getCdmaEcio ()

Get the CDMA Ec/Io value in dB*10

Returns
int

getCdmaLevel

Added in API level 17
public int getCdmaLevel ()

Get cdma as level 0..4

Returns
int

getDbm

Added in API level 17
public int getDbm ()

Get the signal strength as dBm

Returns
int min(CDMA RSSI, EVDO RSSI) of the measured cell.

getEvdoDbm

Added in API level 17
public int getEvdoDbm ()

Get the EVDO RSSI value in dBm

Returns
int

getEvdoEcio

Added in API level 17
public int getEvdoEcio ()

Get the EVDO Ec/Io value in dB*10

Returns
int

getEvdoLevel

Added in API level 17
public int getEvdoLevel ()

Get Evdo as level 0..4

Returns
int

getEvdoSnr

Added in API level 17
public int getEvdoSnr ()

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

Returns
int

getLevel

Added in API level 17
public int getLevel ()

Retrieve an abstract level value for the overall signal quality.

Returns
int Value is between SIGNAL_STRENGTH_NONE_OR_UNKNOWN and SIGNAL_STRENGTH_GREAT inclusive

hashCode

Added in API level 17
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.

Returns
int a hash code value for this object.

toString

Added in API level 17
public String toString ()

Returns a string representation of the object.

Returns
String string representation.

writeToParcel

Added in API level 17
public void writeToParcel (Parcel dest, 
                int flags)

Implement the Parcelable interface

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.PARCELABLE_WRITE_RETURN_VALUE. Value is either 0 or a combination of Parcelable.PARCELABLE_WRITE_RETURN_VALUE, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
