Re: [APP][Official][2.1+] Lux Auto Brightness 0.76

Sorry. Spoke too soon. Crashes every time now. After crashing it opens the intents menu. Had to go back to the pre alpha build.

Ah. Well poop. Which program do you recommend to use for logs?

I'll check Dropbox now.

The intent menu is so you can send me a crash log. Did you try the latest beta? I've been uploading new versions all day.

Do you have a version I can test out? Plugging/unplugging the charger still causes it to spas out like crazy. I think the lux lite beta you posted a few pages back is better than the paid version on playstore.

EDIT: PMed email.

Was thinking of giving this app a chance and went to XDA immediately to see some thoughts on it. Looks like there's an awesome amount of support and feedback! I will def give this a shot.

Another bug I found w/ the beta paid version.

-uncheck persistent notification
-close settings window
-open dashboard
-close dashboard
-kill all recent apps --> Lux will get killed because lack of perisistent notification but will restart
-when it restarts --> notification will reappear

Anybody else getting this issue?

Btw, I'm still still getting a crazy spastic series of screen flickering most likely due to the fact that lux gets killed and restarts repeatedly usually when the charger is plugged in but sometimes even when the sensor is covered or it is too dark.

I tried out a different autobrightness app and realized that it too was going crazy but i think it is more basic and doesnt ignore 0lux readings and so it was flickering between 0 and 6 lux. It's possible that my light sensor is too sensitive and so the app doesnt know whether it should ignore 0lux and set to max brightness or that it is actually just super dark. I hope that makes sense.

Latest beta fixes that notification issue. I can see what's causing your weird flickering issue, but I have no idea why it happens. I'm still investigating, but so far it seems like a ROM based issue.

Does the LG Optimus G ask for root rights?
It shouldn't.

It shouldn't.

I using an OG while I RMA my N4, and it has the same issue I was having w/the N4. Looks like SwipePad conflicts on this phone as well.

Lux only seems to be problematic if SwipePad has a hotspot activated in the top (corners).

This has been an issue with my phones for weeks now. I had narrowed it down to a SwipePad conflict with Vito, but not to the point of which hotspot caused the issue. This was driving me mad until the beta build which with root access on the N4 was fixed. THANK YOU!

Have yet to see an accessible version with root access, look forward to not having to choose one over the other.

    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.

    ★FEATURES★

    ■ Automatic night mode, to change the colour temperature of the display for comfortable night time viewing.
    ■ Add app specific exceptions via sleep mode

    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.
