Example 2 with CellTowerCdma

use of com.vonglasow.michael.satstat.data.CellTowerCdma in project satstat by mvglasow.

the class RadioSectionFragment method updateCellData.

/**
 * Updates all cell data.
 *
 * This method is called whenever any change in the cell environment (cells in view or signal
 * strengths) is signaled, e.g. by a call to a {@link android.telephony.PhoneStateListener}. The
 * arguments of this method should be filled with the data passed to the
 * {@link android.telephony.PhoneStateListener} where possible, and null passed for all others.
 *
 * To force an update of all cell data, simply call this method with each argument set to null.
 *
 * If any of the arguments is null, this method will try to obtain that data by querying
 * {@link android.telephony.TelephonyManager}. The only exception is {@code signalStrength}, which
 * will not be explicitly queried if missing.
 *
 * It will first process {@code aCellInfo}, then {@code aLocation}, querying current values from
 * {@link android.telephony.TelephonyManager} if one of these arguments is null. Next it will process
 * {@code signalStrength}, if supplied, and eventually obtain neighboring cells by calling
 * {@link android.telephony.TelephonyManager#getNeighboringCellInfo()} and process these. Eventually
 * it will refresh the list of cells.
 *
 * @param aLocation The {@link android.telephony.CellLocation} reported by a
 * {@link android.telephony.PhoneStateListener}. If null, the current value will be queried.
 * @param aSignalStrength The {@link android.telephony.SignalStrength} reported by a
 * {@link android.telephony.PhoneStateListener}. If null, the signal strength of the serving cell
 * will either be taken from {@code aCellInfo}, if available, or not be updated at all.
 * @param aCellInfo A list of {@link android.telephony.CellInfo} instances reported by a
 * {@link android.telephony.PhoneStateListener}. If null, the current value will be queried.
