Public Methods

public int describeContents ()

Since: API Level 7
Returns
  • a bitmask indicating the set of special object types marshalled by the Parcelable.

public boolean equals (Object o)

Since: API Level 7

Compares this instance with the specified object and indicates if they are equal. In order to be equal, o must represent the same object as this instance using a class-specific comparison. The general contract is that this comparison should be reflexive, symmetric, and transitive. Also, no object reference other than null is equal to null.

The default implementation returns true only if this == o. See Writing a correct equals method if you intend implementing your own equals method.

The general contract for the equals and hashCode() methods is that if equals returns true for any two objects, then hashCode() must return the same value for these objects. This means that subclasses of Object usually override either both methods or neither of them.

Parameters
o the object to compare this instance with.
Returns
  • true if the signal strengths are the same

public int getCdmaDbm ()

Since: API Level 7

Get the CDMA RSSI value in dBm

public int getCdmaEcio ()

Since: API Level 7

Get the CDMA Ec/Io value in dB*10

public int getEvdoDbm ()

Since: API Level 7

Get the EVDO RSSI value in dBm

public int getEvdoEcio ()

Since: API Level 7

Get the EVDO Ec/Io value in dB*10

public int getEvdoSnr ()

Since: API Level 7

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

public int getGsmBitErrorRate ()

Since: API Level 7

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

public int getGsmSignalStrength ()

Since: API Level 7

Get the GSM Signal Strength, valid values are (0-31, 99) as defined in TS 27.007 8.5

public int hashCode ()

Since: API Level 7

Returns an integer hash code for this object. By contract, any two objects for which equals(Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

Note that hash values must not change over time unless information used in equals comparisons also changes.

See Writing a correct hashCode method if you intend implementing your own hashCode method.

Returns
  • hash code

public boolean isGsm ()

Since: API Level 7

Returns
  • true if this is for GSM

public String toString ()

Since: API Level 7

Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression:

   getClass().getName() + '@' + Integer.toHexString(hashCode())

See Writing a useful toString method if you intend implementing your own toString method.

Returns
  • string representation.

public void writeToParcel (Parcel out, int flags)

Since: API Level 7
Parameters
out The Parcel in which the object should be written.
flags Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE.
