Android Tutorial 65

In your project, edit the file MyFirstAndroidApp.java and create a

new method called forceError() in your class and make a call to this

method in your onCreate() method.

The forceError() method forces a new unhandled error in your

application.

The forceError() method should look something like this:

public void forceError() {
if(true) {
throw new Error(“Whoops”);
}
}

It’s probably helpful at this point to run the application and watch

what happens. Do this using the Run Configuration first. In the

emulator, you see that the application has stopped unexpectedly.

You are prompted by a dialog that enables you to forcefully close

the application, as shown in Figure.

Shut down the application and the emulator. Now it’s time to

debug. You can debug the MyFirstAndroidApp application using the

following steps:

1. Choose the Debug As icon drop-down menu on the toolbar (the little green
   bug with the drop-down arrow).


2. Pull the drop-down menu and choose the Debug Configuration you
   created. (If you do not see it listed, choose the Debug Configurations...
   item and select the appropriate configuration. The Debug Configuration
   shows up on this drop-down list the next time you run the configuration.)


3. Continue as you did with the Run Configuration and choose the
   appropriate AVD and launch the emulator again, unlocking it if needed.
