Running the App

To build and run the app I followed the documentation on the Android Developers website. There are two options to run the app: Run on a real device or run on an emulator. The app runs on both a real device and an emulator.

Here is a link to the Android Developers Documentation to Running the App: https://developer.android.com/training/basics/firstapp/running-app

Run on a real device

Set up your device as follows:

1. Connect your device to your development machine with a USB cable. If you're developing on Windows, you might need to install the appropriate USB driver for your device.
2. Enable USB debugging in the Developer options as follows. First, you must enable the developer options:
   • Open the Settings app.
   • (Only on Android 8.0 or higher) Select System.
   • Scroll to the bottom and select About phone.
   • Scroll to the bottom and tap Build number 7 times.
   • Return to the previous screen to find Developer options near the bottom.

Open Developer options, and then scroll down to find and enable USB debugging.

Run the app on your device as follows:

1. In Android Studio, click the app module in the Project window and then select Run > Run (or click Run in the toolbar).
2. In the Select Deployment Target window, select your device, and click OK.

Android Studio installs the app on your connected device and starts it.

Run on an emulator

Run the app on an emulator as follows:

1. In Android Studio, click the app module in the Project window and then select Run > Run (or click Run in the toolbar).
2. In the Select Deployment Target window, click Create New Virtual Device.
3. In the Select Hardware screen, select a phone device, such as Pixel, and then click Next.
4. In the System Image screen, select the version with the highest API level. If you don't have that version installed, a Download link is shown, so click that and complete the download.
5. Click Next.
6. On the Android Virtual Device (AVD) screen, leave all the settings alone and click Finish.
7. Back in the Select Deployment Target dialog, select the device you just created and click OK.

Android Studio installs the app on the emulator and starts it.
