SimpleCalc Sample App (Starter Code)

SimpleCalc is a simple calculator app, with a handful of problems. This app is used to explore the Android Studio debugger. It's also the basis for learning about unit testing in SimpleCalcTests.


For this app you should be familiar with:

  • Creating an Android Studio project, and working with EditText and Button views.
  • Building and running your app in Android Studio, in both an emulator and on a device.
  • Adding log statements and viewing the system log (logcat) in Android Monitor.

Getting Started

  1. Download and open this sample in Android Studio.
