runtimeexception

I am trying to read csv file full of text; however if there is a blank line in the middle somewhere, the whole thing breaks and I get a: java.lang.RuntimeException: java.lang.StringIndexOutOfBoundsException How would I go about removing/ignoring blank lines as long as it's not the end of the file? file = new FileReader(fileName); @SuppressWarnings("resource") BufferedReader reader = new BufferedReader(file); while ((line = reader.readLine()) != null) { //do lots of stuff to sort the data into lists etc } } catch (Exception e) { System.out.println("INPUT DATA WAS NOT FOUND, PLEASE PLACE FILE

I am trying to record audio in my app on a LG G Watch. The following code throws RuntimeException with message "start failed: -2147483648" at the statement "recorder.start();". Wondering what I'm doing wrong here. I have tried a lot of different set of parameters, for example for AudioSource: recorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT); //-and- recorder.setAudioSource(MediaRecorder.AudioSource.MIC); Also for OutputFormat I have tried recorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT); //-and- recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4); //-and- recorder

I am working on a java web application and I have a few questions regarding design. Basically in its current version, it relies heavily on catching exceptions to determine the flow of control .

I'm trying to extend my main Activity to "ListActivity" (previously extends to: Activity) to use onListItemClick, but the logcat, send me "Your content must-have a ListView whose id attribute is 'android.r.id.list'". (i'm using SQLite for populate the ListView). mi xml is: <ListView android:id="@+id/list" // to "@id/android:list" or other styles (but nothing works) android:layout_width="fill_parent" android:layout_height="fill_parent"/> // or closing with </ListView> this is the complete xml for the ListView: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas

Let's say we have the following program: class Fruit {} class Apple extends Fruit {} class Jonathan extends Apple {} class Orange extends Fruit {} public class Main { public static void main(String[] args) { Fruit[] fruit = new Apple[10]; try { fruit[0] = new Fruit(); // ArrayStoreException fruit[0] = new Orange(); // ArrayStoreException } catch(Exception e) { System.out.println(e); } } } Based on the Java documentation : Thrown to indicate that an attempt has been made to store the wrong type of object into an array of objects. I've read here that When array is created it remembers what type

I've developed an app which has got a service taking snapshots in the background. Whilst this app runs okay in all the devices I've tried so far (not Motorola ones), I found that running it on a Bionic Droid, crashes. Basically, what I'm doing is: camera = Camera.open(); camera.setParameters(parameters); camera.setPreviewDisplay(null); camera.startPreview(); camera.takePicture(null,null,callback); This sequence works with no issues on different HTC and Samsung devices running from Android 2.2 to Android 2.3.4 The Bionic is running 2.3.4 and the takePicture method throws a RuntimeException at
