From 30cf45f14ff8217ee999fc7ff41f7784fd59127d Mon Sep 17 00:00:00 2001 From: Dominik Riebeling Date: Thu, 12 May 2011 22:20:55 +0200 Subject: [PATCH 2/2] Android: listen to ACTION_AUDIO_BECOMING_NOISY for headphone. This event is sent before the audio is routed back to the speaker so we get the information about the unplugged headphone notably earlier. Decrease the debouncing of the headphone status from 1s to 0.5s to work around audio still getting played back via the speaker due to the pause delay by debouncing. On Android we shouldn't need the debouncing at all. --- android/src/org/rockbox/RockboxService.java | 16 ++++++++++++++++ firmware/drivers/button.c | 2 +- 2 files changed, 17 insertions(+), 1 deletions(-) diff --git a/android/src/org/rockbox/RockboxService.java b/android/src/org/rockbox/RockboxService.java index ed47442..a87cec4 100644 --- a/android/src/org/rockbox/RockboxService.java +++ b/android/src/org/rockbox/RockboxService.java @@ -67,11 +67,13 @@ public class RockboxService extends Service private IntentFilter ifh; private BroadcastReceiver batt_monitor; private BroadcastReceiver headphone_monitor; + private BroadcastReceiver noisy_monitor; private RunForegroundManager fg_runner; private MediaButtonReceiver mMediaButtonReceiver; private int battery_level; private int headphone_state; private ResultReceiver resultReceiver; + private RockboxService rbservice; public static final int RESULT_INVOKING_MAIN = 0; public static final int RESULT_LIB_LOAD_PROGRESS = 1; @@ -367,6 +369,20 @@ public class RockboxService extends Service } }; registerReceiver(headphone_monitor, ifh); + noisy_monitor = new BroadcastReceiver() + { + @Override + public void onReceive(Context context, Intent intent) + { + LOG("audio becoming noisy"); + headphone_state = 0; + } + }; + rbservice = RockboxService.get_instance(); + /* We're relying on internal API's here, + this can break in the future! */ + rbservice.registerReceiver(noisy_monitor, + new IntentFilter("android.media.AUDIO_BECOMING_NOISY")); } diff --git a/firmware/drivers/button.c b/firmware/drivers/button.c index f8e4a35..3ee5e7c 100644 --- a/firmware/drivers/button.c +++ b/firmware/drivers/button.c @@ -177,7 +177,7 @@ static void button_tick(void) /* Use the autoresetting oneshot to debounce the detection signal */ phones_present = !phones_present; timeout_register(&hp_detect_timeout, btn_detect_callback, - HZ, phones_present); + HZ/2, phones_present); } #endif -- 1.7.4.4
