I am getting the value from webservice. Some of my values come with single quotes. Like this sample's sqlite is not supporting single quotes. So I replace them with double quotes. While I then retrieve the value from db, I am not able to parse the value. I am getting parser exception not wellformed. Can anybody tell me how to do this?

this is my code replacing single quote to double quote

              stockservicevalue=stockservicevalue.replaceAll("'", "\"");

this is my retrieving value from db

String sql = "SELECT * FROM MyQuest;";

The log:

stockservicevalue=stockservicevalue.replaceAll("'", "\''"); 


We can make use android DatabaseUtils class.

stockservicevalue= DatabaseUtils.sqlEscapeString(stockservicevalue);


I think the correct format would be stockservicevalue=stockservicevalue.replaceAll("\'", "\"");


How to insert single quote with SQLite Java. It works for me.

String str = "'Hello";

str = str.replace("'","\\'");
