Paper with kotlin: write and read function is not working #156

Hi, sorry for asking a question. I would like to ask how to make it works? I have added dependency and initialize Paper, but the function still not working ("write" function do not replace the value of the parameter; "read" function caused the application fail/not working).

This is my class where the value will store: class Prevalent { companion object{ val UserPhoneKey : String = "UserPhone" val UserPasswordKey : String = "UserPassword" }}

Those is the lines I used Paper library: ->write function Paper.book().write(Prevalent.UserPhoneKey, phoneNo) Toast.makeText(this@LoginActivity, "test ${Prevalent.UserPhoneKey} test", Toast.LENGTH_LONG).show() *Toast show default value instead of showing phone number

->read function val userPhone:String = Paper.book().read(Prevalent.UserPhoneKey) *tried a lot of times, read function cause application fail

Sorry for my bad English.

Thank you for your help.

Do not use Paper.book().write and read functions in UI thread, that may cause the issue.

If you can provide more detailed error message or stacktrace I probably can give more detailed answer.

It is worked after I restart android studio. Maybe the implementation did not start after I add its dependency.

Thank you for your help!
