Usage

Handling Flashlight states

1. Declare permissions in your app's AndroidManifest.xml file

   <!-- Permissions : Allows access to flashlight --> <uses-permission android:name="android.permission.CAMERA"/> <uses-permission android:name="android.permission.FLASHLIGHT"/>

2. Init code.

   Make sure you have checked for Manifest.permission.Camera permission first

   Lantern.getInstance().init(context);
   

3. Manage states via

   • Turn On

     Lantern.getInstance().turnOnFlashlight(context);
     

   • Turn Off

     Lantern.getInstance().turnOffFlashlight(context);
     

Handling Display/Screen states

1. Declare permissions in your app's AndroidManifest.xml file

   <!-- Permissions : Allows access to change settings --> <uses-permission android:name="android.permission.WRITE_SETTINGS"/>

2. Keep screen on

   • Enable: Keep display on

     Lantern.getInstance().keepDisplayOn(activity)

   • Disable: Keep display on

     Lantern.getInstance().clearKeepDisplayOn(activity)

Below requires that you have permission to write to system settings.

1. Make use of helper functions

   • Check if the permission to write to system settings is granted or not

     Lantern.getInstance().checkSystemWritePermission(activity)

   • If not granted, request for the same

     Lantern.getInstance().requestSystemWritePermission(activity)

2. Handle states

   • Set display/screen to full bright state

     Lantern.getInstance().setDisplayToFullBright(activity)

   • Reset display/screen to auto-bright state

     Lantern.getInstance().resetDisplayToAutoBright(activity)

Pull Requests

I welcome and encourage all pull requests. It usually will take me within 24-48 hours to respond to any issue or request. Here are some basic rules to follow to ensure timely addition of your request:

1. Match coding style (braces, spacing, etc.) This is best achieved using CMD+Option+L (Reformat code) on Mac (not sure for Windows) with Android Studio defaults. The code style used in this project is from Grandcentrix, so please use the same when editing this project.
2. If its a feature, bugfix, or anything please only change code to what you specify.
3. Please keep PR titles easy to read and descriptive of changes, this will make them easier to merge :)
4. Pull requests must be made against develop branch. Any other branch (unless specified by the maintainers) will get rejected.
5. Check for existing issues first, before filing an issue.
6. Have fun!
