NullPointerException on getReadableDatabase()

Question

I have this method in a class (non-activity) -

public boolean usernameChk(String usrname) {

    String usrnmQuery = \"SELECT * FROM \" + TABLE_ACCOUNTS + \"         


        

Answer 1

The Context you pass to your DatabaseHandler constructor is null.

That's the explanation for the NPE in getDatabaseLocked(). To get help fixing that, post code where you initialize the context.
