Issue with building Android App in Ionic

Question

On trying to build the Android app for my ionic project I get the error stack trace below

C:\\Users\\Peter Okocici\\WebstormProjects\\Pido\\pido-project\\pido\\platforms\\android\\res\\drawable-hdpi\\drawable-hdpi-icon.png: Error: Invalid file name: must contain only lowercase letters and digits ([a-z0-9_.])

I have spent hours on this, no matter what I do this error stays.

Find above the config file

Answer 1

The error message tells you that drawable-hdpi-icon.png is not a valid filename. Android resource filenames cannot contain hyphens ( - ) - only lower case letters, numbers and underscores. Rename your file and you should be good.

Answer 2

Move your project to a new folder where there are no spaces in the directory

eg C:\\WebstormProjects\\Pido\\
