Sketch Export for Android

renameAndroid.py

'''
A cheeky little python script that renames and correctly
puts exported image assets from Sketch into the correct 
drawable folders for Android. 

Images sizes supported 1x, 2x, 3x, 4x, 0.5x, 1.5x
The code is pretty simple so if you want to add support for 
other sizes, it is easy to do. 

To use: 
Export all the image sizes from Sketch.
Make sure they have a suffix of @1x @2x etc.
Copy python file to folder where the images are contained. 
Run the script.

Note: this will overwrite files without any warnings.
Use at your own risk.
