    <p>I’m developing an <code>Android</code> application and I want it to interact with <code>headset</code> button clicks. I’m testing it in a <strong>Nexus 5 with Android KitKat 4.4</strong>.</p> <p>I tried first with a simple headset (not wireless). The button event received was <code>KEYCODE_HEADSETHOOK</code> (79). I created a <code>MEDIA_BUTTON</code> <code>receiver</code> to handle its clicks:</p> <pre><code>&lt;receiver android:name="com.example.mytest.SearchActivity$MediaButtonIntentReceiver"&gt; &lt;intent-filter&gt; &lt;intent-filter android:priority="1000000000"&gt; &lt;action android:name="android.intent.action.MEDIA_BUTTON" /&gt; &lt;/intent-filter&gt; &lt;/intent-filter&gt; &lt;/receiver&gt; </code></pre> <p>This is the activity holding the receiver:</p> <pre><code>public class SearchActivity extends Activity { private AudioManager mAudioManager; private ComponentName mAudioReceiver; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.search); mAudioManager = (AudioManager) getSystemService(AUDIO_SERVICE); mAudioReceiver = new ComponentName(getPackageName(), MediaButtonIntentReceiver.class.getName()); } @Override protected void onResume() { super.onResume(); mAudioManager.registerMediaButtonEventReceiver(mAudioReceiver); } @Override protected void onPause() { super.onPause(); mAudioManager.unregisterMediaButtonEventReceiver(mAudioReceiver); } public static class MediaButtonIntentReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { Log.d("SA", "ON RECEIVE"); ... abortBroadcast(); } } } </code></pre> <p>This code works with my wired headset <strong>only if the user performs a short click</strong>. Performing a long click opens <code>Google Voice Search</code>. I’d like to capture long clicks too, but I don’t mind if it’s not possible.</p> <p>After that I tested it with a <code>bluetooth</code> headset. Specifically, I’m using Moveteck Bluetooth Headset BH119A (you can see an image at the bottom of this post). This headset only has one button, and if I press it the following "<code>activity</code>" is opened:</p> <p><img src="https://i.stack.imgur.com/FgeNF.png" alt="enter image description here"></p> <p>I’d like to capture this click event too if my <code>Activity</code> is opened. How can I do it? I tried adding the following filters to my receiver, but it’s not working either:</p> <pre><code>&lt;action android:name="android.bluetooth.headset.action.VENDOR_SPECIFIC_HEADSET_EVENT" /&gt; &lt;action android:name="android.intent.action.VOICE_COMMAND" /&gt; &lt;action android:name="android.intent.action.CALL_BUTTON" /&gt; </code></pre> <p>I also tried overriding <code>onKeyDown</code> in my Activity, but it’s not triggered.</p> <p>Anybody knows how can I intercept those events?</p> <p>This is my bluetooth headset:</p> <p><img src="https://i.stack.imgur.com/zPDvy.jpg" alt="enter image description here"></p> <hr> <p>** EDIT **</p> <p>Following Toaster’s advice, I checked the whole log looking for the events my headset triggers.</p> <p><strong>Wired headset long click</strong></p> <p>This is the log when I long click in my wired headset (it opens <code>Google Voice Search</code>):</p> <pre><code>12-10 09:24:36.644: I/MediaFocusControl(740): voice-based interactions: about to use ACTION_WEB_SEARCH 12-10 09:24:36.644: I/ActivityManager(740): START u0 {act=android.speech.action.WEB_SEARCH flg=0x10800000 cmp=com.google.android.googlequicksearchbox/.SearchActivity} from pid 740 12-10 09:24:36.754: I/ActivityManager(740): START u0 {act=android.speech.action.WEB_SEARCH flg=0x10000000 cmp=com.google.android.googlequicksearchbox/com.google.android.launcher.GEL} from pid 10153 12-10 09:24:36.764: I/InputDispatcher(740): Dropping event because there is no focused window or focused application. 12-10 09:24:36.764: I/InputDispatcher(740): Dropping event because there is no focused window or focused application. 12-10 09:24:36.774: I/GEL(1025): handleIntent(Intent { act=android.speech.action.WEB_SEARCH flg=0x10400000 cmp=com.google.android.googlequicksearchbox/com.google.android.launcher.GEL }) 12-10 09:24:36.774: V/SearchControllerCache(10153): creating SearchController 12-10 09:24:36.804: I/AudioRouter(10153): ROUTE_NONE-&gt;ROUTE_NO_BLUETOOTH 12-10 09:24:36.804: I/MediaFocusControl(740): AudioFocus requestAudioFocus() from android.media.AudioManager@4267ad58com.google.android.voicesearch.audio.AudioRouterImpl$1@42695f60 12-10 09:24:36.804: I/Velvet.SdchManager(10153): Sdch cache load complete. 12-10 09:24:36.814: W/IInputConnectionWrapper(18407): showStatusIcon on inactive InputConnection 12-10 09:24:36.814: I/Icing.InternalIcingCorporaProvider(10153): Updating corpora: A: NONE, C: DELTA 12-10 09:24:36.854: I/VS.G3EngineManager(10153): create_rm: m=GRAMMAR,l=en-US 12-10 09:24:36.854: W/Search.ConcurrentUtils(10153): Executor queue length is now 9.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
