[Android][Java][solved] Invalid character constant

Solution is change the code from

viewedRecordDao.viewArticle('sdgd','sdgsg');

to:

viewedRecordDao.viewArticle("sdgd","sdgsg");

Reason :
I use this line of statement to pass the parameters to a function in another class.
The parameters are in String Type

public int viewArticle(String articleId, String articleSection){
        Log.d("ViewRecordDao","Save View article_id");
        return 0;
}

text within " " is String in java & within ' ' is for one character.
So if you want pass String but not char in Java, use "" and not ''
