19 import @1.0::ITunerCallback;
22 * Some methods of @1.1::ITunerCallback are updated versions of those from
23 * @1.0:ITunerCallback. All 1.1 HAL implementations must call both
24 * (eg. tuneComplete and tuneComplete_1_1), while 1.1 clients may ignore 1.0
25 * ones, to avoid receiving a callback twice.
27 interface ITunerCallback extends @1.0::ITunerCallback {
29 * Method called by the HAL when a tuning operation completes
30 * following a step(), scan() or tune() command.
31 * @param result OK if tune succeeded or TIMEOUT in case of time out.
32 * @param info A ProgramInfo structure describing the tuned station.
34 oneway tuneComplete_1_1(Result result, ProgramInfo info);
37 * Method called by the HAL when a frequency switch occurs.
38 * @param info A ProgramInfo structure describing the new tuned station.
40 oneway afSwitch_1_1(ProgramInfo info);
43 * Called by the HAL when background scan initiated by startBackgroundScan
44 * finishes. If the list was changed, programListChanged must be called too.
45 * @param result OK if the scan succeeded, client may retrieve the actual
46 * list with ITuner::getProgramList.
47 * TEMPORARILY_UNAVAILABLE if the scan was interrupted due to
48 * hardware becoming temporarily unavailable.
49 * NOT_INITIALIZED other error, ie. HW failure.
51 oneway backgroundScanComplete(ProgramListResult result);
54 * Called each time the internally cached program list changes. HAL may not
55 * call it immediately, ie. it may wait for a short time to accumulate
56 * multiple list change notifications into a single event.
58 * It may be triggered either by an explicitly issued background scan,
59 * or a scan issued by the device internally.
61 * Client may retrieve the actual list with ITuner::getProgramList.
