Lux plugin for Galaxy S users now available!

Hi everyone,

For anyone here who uses a Galaxy S and Lux too, you may be interested to know that I have developed a Lux for SGS root plugin which is now available.

Unfortunately, as a new user, I'm not in a position to post direct links yet so apologies for the inconvenience caused by having to insert links into code tags!

Seems my app is broken once again for me. This time 0%-100% looks all the same, it's like it's stuck on a lux setting. "Clear data" doesn't help. Restarting the phone doesn't help. Reinstalling doesn't help. The stock rom light setting seems to work fine. Debug data looks ok. Seems this app, at least for me is broken for good. I haven't tried to reset the phone, though I don't see why I should be forced to...
Samsung N7100 stock rom 4.1.2

Ok, sorry. I should've thought of checking recent app installs before blaming Lux as I've had it happen with other apps. It seems the app OneClick Scroll makes Lux not work properly and introduces the above bug (I did a few installs/uninstalls of OCS).

On my Sony Xperia Tablet Z, whenever I have the keyboard open the Night Mode overlay flickers in and out. Any idea how to fix that? Ive tried the alternate overlay to no avail.

Thanks much, love the app.

Lux doesn't interact very well with my LG Optimus G's system brightness control (with CM it was fine, but with stock rom it is a mess)
I gave up, I would like to use the stock brightness control and Lux just for subzero, I would like to leave Lux always sleeping and manually set it to subzero when I need it
but when I put it to sleep, after some minutes it leaves this sleeping condition, how can I set Lux to always sleep until I wake it up manually?

Would it be possible to update to app so you can override Android's "auto low brightness on low battery" (5% I think). I was surprised when it happened (my first smartphone). First I thought it was Lux, though it was easy to guess what the problem was when I saw the brightness setting was disabled in settings.

Does this flicker occur without night mode enabled?

You can disable Lux in advanced settings. I'll look into sleep issues.

How can i change profile using tasker or trigger?
Use Tasker as normal and select the 'Lux plug-in' that should be available within the app.

I'm not aware of an option to override ROM battery features.

I'm trying, but these kernels are not designed to change RGB in realtime. They require the display to be turned off/on to apply the settings.

Well by default Lux decides the brightness upon wake, would it not be possible to have it so that when the device has the screen off, when you press the power button instead of instantly bringing the screen on it would calculate how much of a sub zero or night mode colour profile to apply, apply it and then bring the screen on?

Edit: actually, franco.Kernel Updater is able to apply the new colour profile and refresh the screen quite quickly, could you not have a notification appear in the notification area alerting you that the screen needs to be refreshed to apply subzero or night mode and then have a little button in the Lux Dash or the one in the notification area that can do this quickly like franco.Kernel can?

Well that's what I was hoping to do. If you can work out how to emulate RGB using the gamma sliders, it'll help me out.

    App Description

    Lux isn't your ordinary brightness app. It intelligently adjusts the brightness of your display based on the environment you're in. If, for example, you step into a dimly lit room, Lux will automatically lower the brightness of your display to make it not only comfortable to read, but to also preserve battery power.
    Lux provides the option to automatically adjust the backlight at fixed intervals (periodic mode), when a change in environment is detected (dynamic mode), or when the phone wakes from sleep. It's also possible to adjust the backlight manually. Simply disable automatic mode and you can use it like a traditional brightness tool!
    Perhaps the best thing about Lux is that you can teach it how to behave. If the backlight is too bright or dim for your liking, simply open the provided Dashboard, adjust the brightness slider to the level you desire, then hold the link button. Lux will use this new 'link' as a reference in future.

    Give it a go! I want you to test Lux for more than the 15 minute refund period offered by Google. I understand that some devices may not have the best quality light sensor, and that you may need more time to play around with settings. If you find that Lux doesn't suit you after the 15 minutes is up, you can request a refund at any time via e-mail - no questions asked.

    Lux Low-Level Plug-ins

    Soon Lux will support plug-ins to bypass Android API limitations. These plug-ins serve to replace the overlay system Lux uses to make adjustments for Night/Astronomer modes and brightness in general. The plug-in library is free to use for non-commercial development, and can be found here:

    Lux Plug-in Library | Nexus 4 Sample Plug-in Code

    How to make a plug-in

    There are two approaches to making a plug-in for Lux. The passive and the active method. The former is as easy as providing a set of superuser commands for Lux to interpret and apply. These command correlate to functions such as setting pixel RGB or brightness levels. This is the type of plug-in the Nexus 4 sample linked above takes.
    The active method requires you produce your own code to perform RGB/brightness adjustments. This might include importing a device specific library to do the heavy lifting, and then returning empty superuser commands back to Lux.


    Getting Started

    Simply import the Lux Plug-in Library source into your IDE as an Android Library Project, and then create a new Android app which extends PassiveDisplay.java.

    PassiveDisplay provides hooks into Lux's plug-in framework, which you can use to provide superuser commands for Lux to execute. These commands correlate to functions such as setting RGB values. Take a look at the sample Nexus 4 project to see how it's all done.
    Finally, in your new project's AndroidManifest.xml file, add the following:

    Code:
        <activity
            android:name="com.vitocassisi.lux.plugin.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
    
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    
        <receiver
            android:name="com.vitocassisi.lux.plugin.LuxBroadcastReceiver"
            android:exported="true" >
            <intent-filter>
                <action android:name="com.vitocassisi.lux.plugin.search" />
            </intent-filter>
        </receiver>
    
        <service
            android:name=".[B]MY_PLUGIN[/B]"
            android:exported="true" >
            <intent-filter>
                <action android:name="[B]YOUR_PACKAGE_NAME_HERE[/B]" />
            </intent-filter>
        </service>

    Be sure to replace YOUR_PACKAGE_NAME_HERE with the name of your plug-in's package, and MY_PLUGIN with your extended PassiveDisplay class.

    And that's it! Now you're ready to test!


    Enabling Plug-In support within Lux

    To enable plug-in support, you must check 'Enable plug-in support' in the Advanced section of Lux settings. Enabling this option forfeits all responsibility of mine for any issues caused while using Lux. Plug-in's can cause very real damage to your device if they're written incorrectly - don't use plug-ins from sources you don't trust!
    Testing your plug-in
    Testing is critical for creating a good plug-in. You are dealing directly with system files, and can easily cause damage if you do not know what you're doing.

    DO NOT RELEASE A PLUG-IN WITHOUT TESTING IT ON THE TARGET DEVICE FIRST!

    Ensure that the following work with your plug-in installed:
    • Astronomer Mode
    • Night Mode
    • General brightness adjustment
    • Lux readings functional

    BE METICULOUS WITH YOUR IMPLEMENTATION OF isSupportedDevice()!
    Modifying system files on the wrong model/kernel may cause irreversible issues!

    Hey everyone. Sorry to hear that people are having issues with the paid version. I'm working on hotfixes at the moment. A lot of these bugs don't appear on my test devices, which is why regressions happen seemingly randomly. I'm working hard on finding a reliable way to reproduce and test these issues to prevent this happening again.
