In earlier versions of Android, SystemUI.apk could be extracted along with framework-res,apk, and the resources swapped for status bar icons of my choosing. The edits will be on an AOSP rom based on Nougat or Oreo. I am not working with Sense roms. My understanding is that Oreo further limited the ability to change statusbar icons, that would be my reason for going with Nougat. I would rather stay with an Oreo build of AICP but that is not a must. I do not want white icons on my statusbar.
Most, if not all substratum themes do not touch the status bar icon color, some use overlays to change the background though. There is a substratum overlay for wifi icons but this seems overly complex for such a simple icon swap, and there have been changes made by google to prevent the signal icon from being changed, at least according to the developer.
If you are interested, I would like an estimate to:
1. Tell me which files to pull and send to you 2. Determine where the resources and/or code must be decompiled/edited to make this work, that is, signal, wifi, other icons of my choosing. I can provide the icon files. 3. Send me the edited files 4. I will test 5. Work with me to handle the bugs 6. Once we have a working setup, draft an outline of what you did which would enable me to decompile/edit the appropriate apks or files so I can do this myself later with different icons.
These mods will be done on AICP (Oreo) or Resurrection (Nougat) AOSP (Android Open Source) custom ROMS. HTC M9, rooted, S-OFF. I can provide the full rom zip file if needed. I can provide whatever system files you need from the phone. I am familiar with adb, fastboot, etc and can replace the files on the phone with the edited ones.
Thanks for your consideration. This should be a quick project for the right person.
