Android build fails. Webpack + Jscrambler.

[terreb]

I'm building my vanila nativescript project with webpack + jscrambler. For iOS it builds with no issues, however for Android it fails with "[ERROR] FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory".

My environment:

tns cli 3.3.0

@terreb try increasing your heap with the solution suggested here

[terreb]

@NickIliev, thank you, but I did try all of those before and it didn't help.

The Jscrambler support helped me to fix the issue. This is their reply "...the problem lies in the usage of the duplicateLiterals removal transformation. Since you have a lot of numbers in your source code, the transformation is generating a bundle that can go up to 10 times the size of the original. " I adjusted jscrambler.json like they had suggested and it fixed the issue for me. Maybe this will be useful for someone else struggling with the error.
