I have it going to sleep but not waking up.</p> <p>This sets the wakelock:</p> <pre><code>private void setWakeLock(){ System.out.println("wakelock"); PowerManager pm = (PowerManager)context.getSystemService(Context.POWER_SERVICE); wl = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.ON_AFTER_RELEASE, "DoNotDimScreen"); wl.acquire(); } </code></pre> <p>This sets alarms for wake/sleep times:</p> <pre><code>private void setWakeSleep(){ java.util.Calendar c = java.util.Calendar.getInstance(); c.set(java.util.Calendar.HOUR_OF_DAY, 17); c.set(java.util.Calendar.MINUTE, 53); c.set(java.util.Calendar.MILLISECOND, 0); Intent sleepIntent = new Intent("SLEEP_INTENT"); PendingIntent sleepPendingIntent = PendingIntent.getBroadcast(this, 0, sleepIntent, PendingIntent.FLAG_UPDATE_CURRENT); AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE); alarmManager.set(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), sleepPendingIntent); c.set(java.util.Calendar.HOUR_OF_DAY, 18); c.set(java.util.Calendar.MINUTE, 14); c.set(java.util.Calendar.MILLISECOND, 0); Intent wakeIntent = new Intent("WAKE_INTENT"); PendingIntent wakePendingIntent = PendingIntent.getBroadcast(this, 0, wakeIntent, PendingIntent.FLAG_UPDATE_CURRENT); AlarmManager alarmManager2 = (AlarmManager) getSystemService(ALARM_SERVICE); alarmManager2.set(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), wakePendingIntent); } </code></pre> <p>And this is the broadcast receiver:</p> <pre><code>private BroadcastReceiver receiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { Time updateHour = new Time(); updateHour.set(System.currentTimeMillis()); if (intent.getAction().equals("SLEEP_INTENT")) { System.out.println("sleep"); wl.release(); } if (intent.getAction().equals("WAKE_INTENT")) { wl.acquire(); System.out.println("wake"); //initialise(); } } }; </code></pre> <p>Any help greatly appreciated!</p>
