2. Writing the Code

3. Building and testing the app
There are several ways to test the app, we see how to build and test the app on our own android phone.
Two ways to do the same:

1. Build the apk on system and then copy it to the phone, install and test.
   
   • Build the apk: ionic cordova build android
     Apk is generated at this location ../platforms/android/app/build/outputs/apk/debug
   • Copy the apk to phone through usb or mail or anything.
   • Install the apk and test the funcionality of the app.


2. Using the USB debugging from Developer options on phone.
   • Activate the developer options in phone.Check
   • Turn on USB Debugging in developer options from settings.
   • Run cmd on system: ionic cordova run android --device
   • The above command will install the app on the phone. Now test it.
