How to Make Android Apps 2In this part of my how to make Android apps tutorial I will cover the following topics : strings.xml, Linear Layouts, Toasts, Event Handling, Excepting User Input, Translation, EditText, Button and a whole bunch of other topics.

If you missed part 1 of this series, or if you need to install Android Studio I have you covered with these links. For translation you’ll need the ISO 639-1 Codes as well. All of the code from the video can be found below.

If you like videos like this, it helps me if you share on Google Plus with a click here
