Check whether database is empty

Question

I am trying to check if a sqlite database is empty using

public boolean chkDB(){
        boolean chk = false;
        Cursor mCursor = db.rawQuery(\"SELECT          


        

Answer 1

mCursor.moveToFirst() Returns a boolean of whether it successfully found an element or not. Use it to move to the first row in the cursor and at the same time check if a row actually exists.

Cursor mCursor = db.rawQuery("SELECT * FROM " + DATABASE_TABLE, null);
Boolean rowExists;

if (mCursor.moveToFirst())
{
   // DO SOMETHING WITH CURSOR
  rowExists = true;

} else
{
   // I AM EMPTY
   rowExists = false;
}

You are trying to access a row in the cursor regardless of whether one exists or not.
