Objectives

Errors and Exceptions

start the course
recognize how errors and exceptions can be used in defensive programming
use the Java exception classes
use exception stack traces
test for specific kinds of errors based on domain and code
create custom Java error classes
inform end users of error information in an Android app
use an underlying error object to find out more detail about an error that has occurred
release Java resources in the event of an exception

Automated Unit Testing

recognize how unit testing can be used in defensive programming
use the android testing API to construct automated unit tests
use instrumentation in automated Android unit testing
use test case classes in Android automated unit testing
use Android assertion classes
