Database call crashes Android Application
- by Darren Murtagh
i am using a Android database and its set up but when i call in within an onClickListener and the app crashes
the code i am using is
mButton.setOnClickListener(
new View.OnClickListener()
{
public void onClick(View view)
{
s = WorkoutChoice.this.weight.getText().toString();
s2 = WorkoutChoice.this.height.getText().toString();
int w = Integer.parseInt(s);
double h = Double.parseDouble(s2);
double BMI = (w/h)/h;
t.setText(""+BMI);
long id = db.insertTitle("001", ""+days, ""+BMI);
Cursor c = db.getAllTitles();
if (c.moveToFirst())
{
do {
DisplayTitle(c);
} while (c.moveToNext());
}
}
});
and the log cat for when i run it is:
