Change brightness on Notification

Question

Code for notification:

mNotificationManager = 
             (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
    final Notification notifyDetails = 
            new Notification(R.drawable.ic_launcher,"New Alert, Click Me!",System.currentTimeMillis());
    Context context = getApplicationContext();
      notifyDetails.
    CharSequence contentTitle = "Notification Details...";

    CharSequence contentText = "Browse Android Official Site by clicking me";
    Intent notifyIntent = new Intent(android.content.Intent.ACTION_VIEW,Uri.parse("http://www.android.com"));

    PendingIntent intent1 = 
          PendingIntent.getActivity(this, 0, 
          notifyIntent, android.content.Intent.FLAG_ACTIVITY_NEW_TASK);
    notifyDetails.setLatestEventInfo(context, contentTitle, contentText, intent1);
    mNotificationManager.notify(SIMPLE_NOTFICATION_ID, notifyDetails);

My notification works fine, what I want to happen is the screen brightness to increase to a certain value when the notification pops up.

I used Eclipse's auto complete feature to find the right function, but none work. I also searched quite a bit, no luck.

How do I solve this?

I've had a similar brightness problem some time ago. Take a look at this answer. It should point you in the right direction.

Add this to your activity:

Settings.System.putInt(getContentResolver(),
                    Settings.System.SCREEN_BRIGHTNESS_MODE, Settings.System.SCREEN_BRIGHTNESS_MODE_MANUAL);
Settings.System.putInt(getContentResolver(), Settings.System.SCREEN_BRIGHTNESS, 255);//255 here is your brightness value, an integer that can be between 0 and 255.
float brightness = 1.0f; //Your desired brightness, float value between 0.0 and 1.0
WindowManager.LayoutParams lp = getWindow().getAttributes();
lp.screenBrightness = brightness;
getWindow().setAttributes(lp);

and add this permission to the AndroidManifest.xml:

<uses-permission android:name="android.permission.WRITE_SETTINGS" />

I've just tested it and this code works on Android 4.1.

I don't want to change the brightness with a dummy activity. When my app receives a notification, I'd like the phone's brightness to go up. – Karthik Balakrishnan Jan 15 '13 at 06:15
So don't use the dummy activity part, just use the code that changes the brightness. It's in there. Or do you want me to copy-paste it in here for you? – Anton Cherkashyn Jan 15 '13 at 06:19
Could you show me how I can change the brightness with the notification? With the code, that would be very helpful :) – Karthik Balakrishnan Jan 15 '13 at 06:20
I realized that's the brightness editing part. Should I call the notification after that? – Karthik Balakrishnan Jan 15 '13 at 06:23
Well, that depends on how you want to handle it. I would make it show the notification first and then change the brightness. But I suppose it would work equally well if you did it in reverse order. – Anton Cherkashyn Jan 15 '13 at 06:30
The brightness isn't changing even though I called a notification. – Karthik Balakrishnan Jan 15 '13 at 06:34
Updated the answer once more. I tested this code and it works. – Anton Cherkashyn Jan 15 '13 at 06:55
That is the code I'm using. I forgot tp mention the fact that I'm using a service. So, I want the brightness to update on notification. Do I have to call a dummy activity? – Karthik Balakrishnan Jan 15 '13 at 06:58
Yes, you have to use a dummy activity. – Anton Cherkashyn Jan 15 '13 at 06:59
