Details

In this Android course you will learn the basics of defensive programming in Android. You will learn to work with inputs and creating methods, to deal with errors and creating automated tests. Finally you will learn different Java technologies that are positive for defensive programming for Android applications.

Among subjects covered are URL inputs, SQL, loops, SQlite, Design, Java error classes, API, IDE, UI, ViewAction, ViewInteraction, DataInteraction, assert statements, AsyncTas and far more.

Result

After finishing this course you will be familiar with defensive programming in Android.

Course options

We offer several optional training products to enhance your learning experience. If you are planning to use our training course in preperation for an official exam then whe highly recommend using these optional training products to ensure an optimal learning experience. Sometimes there is only a practice exam or/and practice lab available.

Optional practice exam (trial exam)

To supplement this training course you may add a special practice exam. This practice exam comprises a number of trial exams which are very similar to the real exam, both in terms of form and content. This is the ultimate way to test whether you are ready for the exam.

Optional practice lab

To supplement this training course you may add a special practice lab. You perform the tasks on real hardware and/or software applicable to your Lab. The labs are fully hosted in our cloud. The only thing you need to use our practice labs is a web browser. In the LiveLab environment you will find exercises which you can start immediately. The lab enviromentconsist of complete networks containing for example, clients, servers,etc. This is the ultimate way to gain extensive hands-on experience.
