Overview of this book

This book starts with an introduction of Android Studio and why you should use this IDE rather than Eclipse. Moving ahead, it teaches you to build a simple app that requires no backend setup but uses Google Cloud or Parse instead. After that, you will learn how to create an Android app that can send and receive text and images using Google Cloud or Parse as a backend. It explains the concepts of Material design and how to apply them to an Android app. Also, it shows you how to build an app that runs on an Android wear device. Later, it explains how to build an app that takes advantage of the latest Android SDK while still supporting older Android versions. It also demonstrates how the performance of an app can be improved and how memory management tools that come with the Android Studio IDE can help you achieve this. By the end of the book, you will be able to develop high quality apps with a minimum amount of effort using the Android Studio IDE.

Submitting data to the cloud

Now that we have completed the previous recipes and the driver that will be using our CloudOrder app knows where to go to for a particular order, it would be great if, once the goods are delivered, he (or she) will be able to select that order and have it signed for delivery by the customer on the device.

In this last recipe, we will implement code to make the customer draws his or her signature on the device. The signature will be sent to Parse as an image and the CloudOrder record will be updated.

Getting ready

To go through this recipe, you will need to have the previous recipes up and running.

How to do it…

  1. Create a new class and name it SignatureActivity.

  2. Create a new layout and name it activity_signature.xml.

  3. Switch the layout to Text. Add the TextView and the Button widget to the layout. Make sure that the layout looks like this:

    <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android=""
