Merge changes from topic "nfc_aosp_main_merge" into main
* changes: Adding wallet payment service to log protos for nfc. [nfc] Add disallow nfc change user restriction. Change NFC antenna api comments to indicated top-left start point for all axis. Eliminate boilder plate code for recovering service in NfcAdapter Add Test method to inject HCE data [framework] Add a flag for nfc persist log. Add NFC observe mode + auto-transact dumpsys protos Add NFC observe mode + auto-transact dumpsys logging Fix PollingFrame timestamp documentation Set default discovery technology [framework] Add Nfc oem extension api surface. Pass package name to `NfcService.setObserveMode()` [framework] Expose enable()/disable() as public api. Add POLLING_LOOP_TYPE_UNKNOWN to PollingFrameType Offhost NFC services shouldn't be able to register non-autotransact polling loop filters Document that only the currently preferred service can enable and disable observe mode nfc(api): Move @hide constants to Constants.java Use PollingFrame class instead of Bundles to represent polling frames in NFC stack Make NFC library available to multidevice CTS NFC tests nfc(api): Link against framework-permission KEY_POLLING_LOOP_TIMESTAMP is a long not an int Un-deprecate some NFC methods Reword autoTransact javadoc nfc(api): Change min_sdk to current for framework-nfc Revert^3 "nfc(api): Change min_sdk to V for framework-nfc" [nfc] Pass in package name to nfcService when enabling nfc. Add javadoc for autoTransact parameter Revert^2 "nfc(api): Change min_sdk to V for framework-nfc" Use long for timestamp in PollingFrame Revert "nfc(api): Change min_sdk to V for framework-nfc" nfc(api): Change min_sdk to V for framework-nfc Add API for polling loop pattern filters based on developer feedback. Add Javadoc for PollingFrame constructor Provide information on whether a polling frame is auto-transact Treat gain as an unsigned int Rename getGain() to getVendorSpecificGain() Deprecate methods on CardEmulation in favor of Wallet Role.
