POHow to have LED Light Notification?
text
Body
copied!<p>Update: I am reworking the original post for compatibility before Android 3.0.</p> <p>I am trying to create a simple notification and everything but the light works great. I do have the screen off when the notification fires. Using this deprecated code sound and vibrations works on Android 4.0 (Galaxy Nexus) and Android 2.3 (HTC EVO). </p> <ul> <li>On the 2.3 HTC EVO the lights also work.</li> <li><p>On the 4.0 Galaxy Nexus the lights do not work.</p> <pre><code>Notification notification = new Notification(R.drawable.ic_launcher, "My Ticker!",System.currentTimeMillis()); notification.setLatestEventInfo(context, "My Title", "My Message", pendingIntent); notification.defaults |= Notification.DEFAULT_SOUND; notification.defaults |= Notification.DEFAULT_VIBRATE; //notification.defaults |= Notification.DEFAULT_LIGHTS; notification.ledARGB = 0xff00ff00; notification.ledOnMS = 300; notification.ledOffMS = 1000; notification.flags |= Notification.FLAG_SHOW_LIGHTS; notification.flags |= Notification.FLAG_AUTO_CANCEL; </code></pre></li> </ul> <p>I have also tried newer APIs that are not part of the v4 compatibility library, so I could only test this on the Galaxy Nexus. Vibration and Sound works again but not lights.</p> <pre><code>Notification.Builder builder = new Notification.Builder(context); builder.setContentIntent(pendingIntent) .setSmallIcon(R.drawable.ic_launcher) .setTicker("My Ticker") .setWhen(System.currentTimeMillis()) .setAutoCancel(true) .setDefaults(Notification.DEFAULT_VIBRATE | Notification.DEFAULT_SOUND | Notification.FLAG_SHOW_LIGHTS) .setLights(0xff00ff00, 300, 100) .setContentTitle("My Title 1") .setContentText("My Text 1"); Notification notification = builder.getNotification(); </code></pre> <p>I have now tested this on two stock Galaxy Nexus phones and the light works on neither. The screen IS off when I run the tests and all other apps on the phones trigger the lights without issue.</p>
