Learn the difference between Android local tests and instrumented tests, and how instrumentation works.
- [Voiceover] Native Android code is written in Java.…In any application, there'll be a lot of Android Java code…that has no dependency on Android framework or APIs.…It's just "Plain" Java.…For instance, in a tip calculator app,…code to calculate the tip based on the bill amount…and the desired tip percentage would look the same…in an Android app as it would in any…Java enterprise or web application.…Other parts of an Android application…rely on the Android framework.…For example, the code to display the calculated tip…to the user in an Android screen is going to rely heavily…on the Android user interface APIs.…
Even outside of the user interface APIs,…there are many Android APIs that are not available…or not the same in other Java application environments.…Consider code to fetch a contact from the Android contacts.…Code to react to open the phone app…or code to start an Android asynchronous task.…The type of code, while still written in Java,…is tightly coupled to the Android API.…It requires the Android framework to be in place…
