Error(1,1)illegalcharacter '\ufeff' when compiling on android studio

Question

I got an Eclipse project source code(I was told that on Android Studio, maybe they just confused), and I start to migrating the code to android studio refers to

Answer 1

Just delete the first line of the xml-file and retype it by hand (copy paste would reinsert the hidden BOM).

Answer 2

The ideas in here certainly helped me but the outcome was a little different.

I did convert my file encoding from UTF-8 to UTF-16. I was then presented with a different error. When i converted it back to UTF-8, I noted that there was a string of unrecognizable characters before my code line. I removed them and recompiled and it worked well.

My conclusion is somehow an unrecognizable character snuck into my code. Could be programmer error, or a blind copy/paste from the web that placed a nasty hidden character. Carrying the process above as outlined by our peers here somehow allowed me to see it.

If you'll follow this idea above, please make sure to clean/rebuild between each conversion.

Answer 3

i solved this problem with this method :

1. ctrl + A in my activity and copy all codes
2. delete YourClass.java
3. create YourClass.java
4. paste all code in new java class

Answer 4

I try using sublime, open the file then "Save with Encoding" there choose UTF-8 (without BOM), and it works :)

Answer 5

As Marcelo told, I changed file Encoding option to UTF-16. Ran it, But didn't work. Again changed to UTF-8 and Converted it. It ran successfully. If above solution doesn't work, try this.
