First time posting. Thanks for the help in advance.
I have two activities. First activity reads in 3 numbers from the user via edittext fields whose inputType is “numberDecimal”. It bundles these and sends them to the second activity via intent.
The second activity reads in the 3 numbers. It then needs to multiply them by some constants. That’s where the problem comes in. If the result of the multiplication is too large (say, greater than a couple hundred…not constant threshold…not close to what a double should be able to hold) then it throws an indexoutofboundsexception.
//@SuppressWarnings ("serial)")
public class CreationActivity extends Activity {
@Override
public void onCreate (Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.creation);
TextView txtTitle = (TextView) findViewById(R.id.labelTitle);
TextView txtArtist = (TextView) findViewById(R.id.labelArtist);
TextView txtTime = (TextView) findViewById(R.id.labelTitle);
try {
Bundle extras = getIntent().getExtras();
double Hours;
double Minutes;
double Seconds;
if (extras!=null){
double timerTime[] = extras.getDoubleArray("Time");
Hours = timerTime[0];
Minutes = timerTime[1];
Seconds = timerTime[2];
//next line is where the error happens:
double desired_time = timerTime[0] * 5000;
//do some stuff
}else{
txtTitle.setText("No data");
}
} catch (NumberFormatException e){
}
}
}
And the LogCat is:

It sounds like you are trying to access the 5th (item at position 4) item in an array of length four.
