Is anyone else finding R coding in the Android app to be buggy?

Question

Sometimes, when I look at my code vs the "hint" code, they look identical, but my code doesn't pass the tests.

If I change the layout of my code to emulate the exact position of linebreaks, etc. sometimes that's enough to "fix" it, e.g. in one exercise I moved ELSE to follow immediately after the closing curly brace of the IF statement, instead of having ELSE on a new line - suddenly my code passed!

I think it's something to do with the way the Android app is doing spaces / indents / line breaks. There was another piece of code that I couldn't get to pass at all on the app, so I saved it and exited, then opened up SoloLearn in a web browser on my PC. When I opened the same activity, I could see line breaks in odd places, most importantly part way through setting a parameter, which would obviously cause problems. On the app, to be clear, there were NO line breaks in these locations! When I fixed the layout on the PC, it passed the tests just fine.

Answer 1

Anthony Hasseldine ,

can you please link a code here that has given problems for you?

Answer 2

Lisa have you encountered such bug in the R playground?

Anthony Hasseldine I don't write R but is there any way to consistently reproduce the bug? Does it occur in a specific lesson's test, or the code playground in general? What was your code that failed, and how did you rearrange it to make it work? Maybe it's a problem with syntax but it would be easy to determine from a concrete example.

Answer 3

No, I didn't encounter an issue.

Can you try to reproduce the error and link the code bit?

Answer 4

could it be something in your keyboard or language settings that is using unrecognized or invisible characters?
