Kindle Fire: How to Install APK Files

Android app files can come via an APK file. You can install APK files on the Amazon Kindle Fire tablet by enabling a setting. Just follow these steps.

Note: Be careful about where you have obtained the APK file. Files that come from non-legitimate sources may be corrupted or contain viruses. Please know what you are doing before you proceed.

1. From the Fire, go to one of the following locations depending on your device:
   • 5th to 8th Generation Devices – “Settings” > “Security” > “Apps from Unknown Sources“.
   • 3rd and 4th Generation Devices – “Settings” > “Applications” > “Apps From Unknown Sources“
   • First and Second Generation Devices – “Settings” > “More” > “Device” > “Allow Installation of Applications” and ensure it’s set to “On“.
2. Open the Kindle Fire web browser and download the APK file. You can also transfer APK files from your computer by connecting the Kindle Fire to the computer with a USB cable.
3. Open the notification area (top bar). It should show that the .APK file is downloading. Tap it once the download has finished.
4. Select “Install“.

FAQ

Why is the “Install” button grayed out?

Amazon released an update that does this sometimes. You can usually get around it by pressing the square button next to the circle home button. Then go back to the install screen. Doing that will light up the Install button.

Some people say that using the “Back” button instead of square then returning to the install screen works to light up the Install button.

Here's how to install Google apps on Kindle Fire HD with no rooting required

One of the main reasons to root your Kindle Fire is so you can install the Google Play Store and have access to apps that can't be found in the Amazon Appstore. But if you're worried about voiding the warranty or dealing with the rooting process in general, you can sideload apps. The cool thing about this technique is it doesn't require you to root the device first. Here's how to get most of the Google apps on your Kindle Fire HD or HDX.

For this article I'm using the latest 7-inch Kindle Fire HDX, which runs Amazon's customized version of Android 4.2. This should work the same on the 8.9-inch version too. Keep in mind that when sideloading these apps, not all of the features will work correctly. For instance, on the Google Search app, the Google Now cards don't load like they would on a Nexus 7 or other Android device. All of the APK (the Android application format) files offered here are free, malware free, and free to distribute.

What is sideloading and how do I do it?

Sideloading is the term used to describe installing an app on your Android device from a source other than an official app store. Basically, what you're doing is transferring an APK file from your computer to your tablet or smartphone and installing it directly. Since the Kindle Fire runs a forked version of Android, this is a common practice to get the apps you like on the device.

Before you can sideload an app on the Kindle Fire HD or HDX, you need to enable the feature that allows you to install apps from unknown sources. To do that, go to Settings > Applications and make sure "Apps from Unknown Sources" is turned on.

Next, download this zip file and extract its contents to a convenient location on your computer. The zip file includes the four essential apps you need to install first.

Connect your Kindle Fire to your computer using the included micro-USB cable and transfer the four APKs you just downloaded to your Kindle's Download folder.

Make sure you have ES File Explorer on your Kindle Fire. It's free and available in Amazon's Appstore. This will give you access to the APKs you transfer to your tablet. You'll find the files in Local > Home > Download.

Now perform the following steps in order:

1. Tap to install Google Account Manager and reboot the tablet.
2. Tap to install Google Services Framework and reboot the tablet.
3. Tap to install Google Play Services and reboot the tablet.
4. Tap to install Gmail and reboot the tablet.

Installing Google apps

After those four apps are installed, open the Gmail app (you'll find it listed under the Apps section on the Kindle Fire) and sign in with your Google account. After signing in at the screen shown below, you'll be kicked to the web version of Google to sign in again.

When you're signing in, you'll see various messages about different Google services stopping. You can just tap through them. This is one of the caveats with sideloading Google apps and running them – the apps will still work, it's just kind of annoying having the occasional alert pop up like the one in the screenshot below.

Once you're signed in, you'll be able to run the Gmail app on your Kindle Fire. Here's an example of it running on my Kindle Fire HDX.

Now you can continue to sideload the Google apps you want to use following the same process as above. Transfer them to the Download folder on the Kindle Fire, just like you did with the first set of apps.

Open ES File Explorer, open the Download folder, and tap to install the Google apps you want. For best results, I recommend installing one app at a time and rebooting after each one.

Just click on the following apps to download the APK file and sideload it on the Kindle Fire. In my tests, each of the following work with little to no bugs: Chrome, YouTube, Google Search, Google Music, Google Play Movies, Gmail, and Newsstand.

Summing up

You can find other Google app files in Android forums or an APK repository site like Android Drawer. A word of caution about sideloading apps: Ensure you're getting them from a trusted and secure source. Some apps – especially the ones that claim to give you paid apps for free – in the shady markets contain malware that will wreck you device. We don't condone sideloading paid apps, and in the end it will just get you into trouble. But as long as you're careful and download the apps from a trusted source you should be ok.

While some of the app features don't work the same as on a typical Android device, and the error messages that pop up are a bit annoying, it isn't a deal-breaker. As long as you're able to overlook those caveats and live in the Google ecosystem, sideloading the apps is something you should definitely try.

9 Best Tools For Designing a Mobile App UI

Design can never be static. Every project is different and so is the process that varies as per the product, personal preferences, team size and other relative variables, but when it comes to tools, you will find only a handful that is every designer’s pet. These tools pave the way for planning and brainstorming, help in clear communication of ideas, solve technical troubles to build mind-blowing animations and even sort interactions with the developers. Over the years, the app designers have worked relentlessly to refine their design tool kits so that they can fasten the workflow and execute right design decisions.

These tools pave the way for planning and brainstorming, help in clear communication of ideas, solve technical troubles to build mind-blowing animations and even sort interactions with the developers. Over the years, the app designers have worked relentlessly to refine their design tool kits so that they can fasten the workflow and execute right design decisions.

Yes, evaluating various extensions, plug-ins, tools and online resources have somewhat become necessary for the design cycle. The team must craft out high-performance mobile app solutions and make it a hit in the digital market.

For this, it is important to have some of the easy-to-use design tools that can transform your raw ideas in the most creative way and can collect useful feedback at an early stage of mobile app development. Here is a list of some of the amazing mobile app design tools, which will render your workflows, screens and pitches more robust with each project-

1. Sketch

Although Photoshop is a personal favorite with the designers, still some have made a switch to Sketch. This super graphic design tool possesses similarity to Photoshop but is more focused on UI/UX design. The tool is powerful, has a wide range of features and brings out professional results. It extends infinite zooming, 2x export, and styled vector shapes which are apt for multiple resolutions. Sketch offers an ‘Export All’ feature and as it is vector-based, there is no problem in exporting PDF, JPG, and PNG (optionally in 2x) files.

Generally, app designers prefer 3 different tools for 3 purposes namely Omnigraffle for wireframing, Photoshop for visual design, and Illustrator for vector logos. All these 3 tools are perfectly aligned with Sketch, thereby making one app fulfill all your needs and achieve overall productivity with no wastage of time.

The sketch is suitable to use owing to its simple operation and the feature which can design the symbols of common elements like buttons, tabs, headers etc with ease. It not only fires up the process of wireframing but also enables an easy hand-off to the visual designers. As we are employing the same tool in the visual design stage, there won’t be much trouble in updating wireframes into high-fidelity visuals.

All the changes that we have witnessed in-app designing have been made possible because of Sketch’s vectorized model, components like multi-resolution exporting and shared styles and symbols.

2. Marvel

The Marvel app converts raw sketches on paper into engaging, tappable prototypes that permit you to demo your app ideas and collect feedback from others. It works perfectly well with .psd files, so you are not required to convert your designs before uploading.

Marvel saves the testing time consumed on changes as it automatically updates them in the background. By replicating the device, the web browser can successfully test your prototype very much in the natural milieu.

Leading you towards most realistic prototyping experience, this tool also gives the benefit of custom animations and fading between screens. Marvel, being an interactive tool, enables designers to import from Sketch, build prototypes of app interactions, animations, and transitions, and further forward these prototypes with stakeholders and developers. It is a convenient way to open up an entire flow to the customer as well, without being bothered by the static user flows.

Here, designers don’t have to be equipped with advanced programs like Framer and After Effects to include animations, transitions and other interesting features in their app layouts. Marvel permits any designer to form transition-based animations over various app screens speedily. The tool is used to prototype an entire app, especially the one with basic transitions in a large number of screens.

3. POP

If you found the Marvel app useful, but you are in search for a working prototype compatible with your Android device, POP app is what you need. It is the best application for mobile prototyping and makes the transition from paper to digital prototyping very easy. All you need to do is to take pictures of your sketches to upload them to POP, or simply upload .psd files to Adobe Creative Cloud. After this, you can smoothly shift between views, gestures, and interactions. As POP is integrated with Dropbox, thus there won’t be any trouble sharing your work with others.

What makes POP app different is that it commences with the images of your hand-drawn app sketches and connects them together onto your mobile. There is no visual constraint in the app as your drawn prototype is compatible with any device.

Run Xcode 7 UI Tests from the command line

Get started with UI Tests to automate User Interface tests in iOS 9

Apple announced a new technology called UI Tests, which allows us to implement User Interface tests using Swift or Objective C code. Up until now the best way to achieve this was to use UI Automation. With UI Tests it’s possible to properly debug issues using Xcode and use Swift or Objective C without having to deal with JavaScript code.

First, you’ll have to create a new target for the UI Tests:

Under the Test section, select the Cocoa Touch UI Testing Bundle:

Now open the newly created Project_UI_Tests.swift file in your Project UI Tests folder. On the bottom you have an empty method called testExample. Focus the cursor there and click on the red record button on the bottom.

This will launch your app. You can now tap around and interact with your application. When you’re finished, click the red button again. 

The generated code will look similar to this. I already added some example XCTAsserts between the generated lines. You can now already run the tests in Xcode using CMD+ U. This will run both your unit tests and your UI Tests.

You could now already run the tests using the CLI without any further modification, but we want to have the UI Tests in a separate scheme. Click on your scheme and select New Scheme.

Select the newly created UI Test target and confirm.

If you plan on executing the tests on a CI-server, make sure the newly created scheme has the Shared option enabled. Click on your scheme and choose Manage Schemes to open the dialog.

Launch the tests from the CLI

xcodebuild -workspace App.xcworkspace \
           -scheme "SchemeName" \
           -sdk iphonesimulator \
           -destination 'platform=iOS Simulator,name=iPhone 6,OS=9.0'
           test

It’s important to also define the version of Xcode to use, in our case that’s the latest beta:

export DEVELOPER_DIR="/Applications/Xcode-beta.app"

You can even make the beta version your new default by running

sudo xcode-select --switch "/Applications/Xcode.app"

Example output when running UI Tests from the terminal:

Generating Screenshots

No extra work needed, you get screenshots for free. By appending the  derivedDataPath option to your command, you tell Xcode where to store the test results including the generated screenshots.

xcodebuild -workspace App.xcworkspace \
           -scheme "SchemeName" \
           -sdk iphonesimulator \
           -destination 'platform=iOS Simulator,name=iPhone 6,OS=9.0' \
           -derivedDataPath './output' \
           test

Xcode will automatically generate screenshots for each test action. For more information about the generated data, take a look at this writeup by Michele.

Next Steps

To create screenshots in all languages and in all device types, you need a tool likesnapshot. snapshot still uses UI Automation, which is now deprecated.

I’m currently working on a new version of snapshot to make use of the new UI Tests features. This enables snapshot to show even more detailed results and error messages if something goes wrong. I’m really excited about this change 👍

Update: snapshot now uses UI Tests to generate screenshots and the HTML summary for all languages and devices.
