Above are great solutions. However, if none of them works, try this one:

Open the file in Notepad++; Copy everything; Create a new file with the same name; Paste everything; Save it.

Now it is gone.

OPEN LOOPView.java File First

Convert Your UTF8 To ISO 8859-1 TO Solve your problem In andorid Studio

In React-native change in index.js / android/index.js

import PropTypes from 'prop-types';

I was facing this error in intelliJ-2016.1.2.

Thank you @Darsh for your help, I did same thing, first changed to UTF-16 (i.e convert into UTF-16) and compiled the code. it didn't work, then again changed back to the UTF-8, this time it worked fine.

Thank you.

Answer 4

You can try to this method:

1. Rename the class like class1.java
2. Create a new class some renamed class like class.java
3. Select all contain renamed file and copy into the new class.

This method work for me.

Answer 5

I tried several of the other answers here with no joy.

In the end I simply deleted the offending line and rewrote it directly into Android Studio. The error disappeared.

Was this caused by me copying and pasting the line of code from youtube (or whatever random blog I was looking at at the time)?

Answer 6

Close android studio and reopen it. It works for me. Furthermore this could happen if you are copying a comment from youtube for example and pasting it into your project
