Hello @MPROCD ,

You can always try a fresh install or a reset. Proceed with caution!

I don’t often use Android Mode but wanted to test out recent versions.

My environment:

- Windows 10
- Processing 4.4.10
- Android Mode for Processing 4.6.1
- Android 15

While Processing is closed:

1. Delete the contents of the _preferences folder_.
2. Delete the _android folder_ from the _Sketchbook folder_
3. Delete _AndroidMode folder_ from the _mode folder_ in the _Sketchbook folder_

Start Processing and select the _Sketchbook folder_ that you will be using.

I then installed Android mode and everything seemed to work as expected and was able to run sketches on my Android 15 phone.

I use a custom location for my _Sketchbook folder_ and preferences:

I was able to create a sketch and run it on my Android 15 device.

Reference for custom _preferences folder_ location::

> \*\*\* UPDATE \*\*\* [Preferences · processing/processing4 Wiki · GitHub](https://github.com/processing/processing4/wiki/Preferences#sketchbook-and-settings-location) To change the default location of the preferences.txt file I used the lib folder here for Processing 4.4.7 and 4.4.10 and it worked: Yay! slight_smile

_Proceed with caution before deleting folders_ and _do so at your own risk_.  
_Ensure you have everything backed up._

What is your environment?  
Can you share a minimal sketch that fails and I can try it on my setup.  
If you do sort this out please share with details.

This is the Android related contents of my _preferences.txt_:

```auto
ANDROID_SDK=E:\AndroidSketchbook\android\sdk
JAVA_HOME=D:\Program_Portable\Processing-4.4.10\app\resources\jdk
PATH=D:\Program_Portable\Processing-4.4.10\app\resources\jdk\bin;E:\AndroidSketchbook\android\sdk\platform-tools;E:\AndroidSketchbook\android\sdk\cmdline-tools\latest;null
