I think I understand the

throw new error("this is an error");

but then what happens? I believe that tells the system that an error occured but if you want to alert the user to this, what is the point of the error() funtion?


try {

// something

} catch (IOException ioe) {

throw new Error( "Unable to access database");
}

where does the user get notified that something is wrong? If I want to just log the data then I could use Log.e() but would I also need the error()?

Hi Mark,

I think you need to read up on some Java OO

http://download.oracle.com/javase/tutor ... owing.html

the Error class ( http://developer.android.com/reference/ ... Error.html ) is just the SuperClass that all exceptions are created from, you shouldn't attempt to catch or throw it.

If you want to inform the user an exception has been raised you would do something.

Code: Select all


try {

// something

} catch (IOException ioe) {

new AlertDialog.Builder(this)
      .setTitle("Error")
      .setMessage("I broke sorry").show();

}
