How to Debug Your Android Wear Apps on a Hardware Device

The Android Wear API brings the Android platform to the newest generation of wearable devices and smartwatches. With Android Wear, you can create a user experience designed specifically for wearables.

But how do you debug your applications? While it is possible to debug most Wear features using the Android emulators, sometimes it is helpful to see the application on a real device.

In this short video tutorial from my recent Android Wear course, I’ll show you how to debug your applications on a physical Wear device.

In the full course, Develop Apps for Android Wear, I'll teach you about the various UI components specifically designed for Android Wear. You will also learn how to extend your application to use the new Wear notification types.

I'll use practical examples to demonstrate how each of these new components can improve your wearable device applications, and I'll also show you how to create a basic digital watch face to help customize your users' experiences.

Filling out PDF Forms with PDFtk and PHP

PDF files are one of the most common ways of sharing documents online. Whether we need to pass our clients’ documents to third-party service providers like banks or insurance companies, or just to send a CV to an employer, using a PDF document is frequently the first option.

PDF files can transfer plain/formatted text, images, hyperlinks, and even fillable forms. In this tutorial, we’re going to see how we can fill out PDF forms using PHP and a great PDF manipulation tool called PDFtk Server.

To keep things simple enough, we’ll refer to PDFtk Server as PDFtk throughout the rest of the article.

Installation

We’ll use Homestead Improved for our development environment, as usual.

Once the VM is booted up, and we’ve managed to ssh into the system with vagrant ssh, we can start installing PDFtk using apt-get:

sudo apt-get install pdftk

To check if it works, we can run the following command:

pdftk --version

The output should be similar to:

How It Works

PDFtk provides a wide variety of features for manipulating PDF documents, from merging and splitting pages to filling out PDF forms, or even applying watermarks. This article focuses on using PDFtk to fill out a standard PDF form using PHP.

PDFtk uses FDF files for manipulating PDF forms, but what is an FDF file?

FDF or Form Data File is a plain-text file, which can store form data in a much simpler structure than PDF files.

Simply put, we need to generate an FDF file from user submitted data, and merge it with the original PDF file using PDFtk’s commands.

What Is Inside an FDF File

The structure of an FDF file is composed of three parts: the header, the content and the footer:
