This code doesn't work for the initial run after installing, but works perfectly later.
In the initial run, the else condition, prepareData() should run, and fill the database.
However, neither the progress bar in prepareData() is showing, nor is the size of mQuestionList getting updated.
So, for the initial run, the if statement if(mcount<mQuestionList.size()) returns false and the code automatically goes to the else block and starts EndActivity. Where am I going wrong?
