    <p>First time posting. Thanks for the help in advance.</p> <p>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.</p> <p>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. </p> <pre><code>//@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){ } } } </code></pre> <p>And the LogCat is:</p> <pre><code>07-27 21:58:41.736: E/AndroidRuntime(31560): FATAL EXCEPTION: main 07-27 21:58:41.736: E/AndroidRuntime(31560): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.decker.timer/com.decker.timer.CreationActivity}: java.lang.IndexOutOfBoundsException: Invalid index 4, size is 4 07-27 21:58:41.736: E/AndroidRuntime(31560): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1956) 07-27 21:58:41.736: E/AndroidRuntime(31560): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1981) 07-27 21:58:41.736: E/AndroidRuntime(31560): at android.app.ActivityThread.access$600(ActivityThread.java:123) 07-27 21:58:41.736: E/AndroidRuntime(31560): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1147) 07-27 21:58:41.736: E/AndroidRuntime(31560): at android.os.Handler.dispatchMessage(Handler.java:99) 07-27 21:58:41.736: E/AndroidRuntime(31560): at android.os.Looper.loop(Looper.java:137) 07-27 21:58:41.736: E/AndroidRuntime(31560): at android.app.ActivityThread.main(ActivityThread.java:4424) 07-27 21:58:41.736: E/AndroidRuntime(31560): at java.lang.reflect.Method.invokeNative(Native Method) 07-27 21:58:41.736: E/AndroidRuntime(31560): at java.lang.reflect.Method.invoke(Method.java:511) 07-27 21:58:41.736: E/AndroidRuntime(31560): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:784) 07-27 21:58:41.736: E/AndroidRuntime(31560): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:551) 07-27 21:58:41.736: E/AndroidRuntime(31560): at dalvik.system.NativeStart.main(Native Method) 07-27 21:58:41.736: E/AndroidRuntime(31560): Caused by: java.lang.IndexOutOfBoundsException: Invalid index 4, size is 4 07-27 21:58:41.736: E/AndroidRuntime(31560): at java.util.ArrayList.throwIndexOutOfBoundsException(ArrayList.java:251) 07-27 21:58:41.736: E/AndroidRuntime(31560): at java.util.ArrayList.get(ArrayList.java:304) 07-27 21:58:41.736: E/AndroidRuntime(31560): at com.decker.timer.CreationActivity.onCreate(CreationActivity.java:172) 07-27 21:58:41.736: E/AndroidRuntime(31560): at android.app.Activity.performCreate(Activity.java:4465) 07-27 21:58:41.736: E/AndroidRuntime(31560): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1049) 07-27 21:58:41.736: E/AndroidRuntime(31560): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1920) 07-27 21:58:41.736: E/AndroidRuntime(31560): ... 11 more 07-27 21:58:49.260: D/TimerActivity(31583): onClicked </code></pre>

    1. COCan you indicate which line in the code you posted corresponds to line 172 in the original source, as per `at com.decker.timer.CreationActivity.onCreate(CreationActivity.java:172)`?

    2. COhmmm...line 172 falls into the //do some other stuff category...let me look into that a bit more. It makes no sense that the multiplication wouldn't work...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
