Using Android Studio

Creating A Basic Watch Face

The main activity for the “wear” module contains a lot of parts. Each doing a certain task to make sure everything runs smoothly. Let’s break it down. These examples are from the chúng tôi from the SDK.


private class Engine extends CanvasWatchFaceService.Engine

This is the implementation of the watch face. Any Paint variables among other variables would go here, for example: Paint mMinutePaint;


public void onCreate

This is where you will setup the UI, including defining your Paint variables, for example: mMinutePaint = new Paint();


mMinutePaint.setARGB(255, 200, 200, 200); mMinutePaint.setStrokeWidth(3.f); mMinutePaint.setAntiAlias(true);

The first line declares a new Paint object. The second line sets the color using ARGB with the first set of three numbers setting the opacity. The third line defines the width of the hand itself and the fourth line turns on antialiasing. One thing to note when creating a background for your app, you can use a higher resolution image like 480×480 and scale it back down to the watch’s resolution, this in turn makes a huge difference and makes the background look a lot better. We were unable to scale the hands. They would need to be made into the exact size required.


boolean mLowBitAmbient;

Some smartwatches have a low bit ambient mode, this is basically a toned down version of the regular ambient mode found on the Moto360 for example. You would want to use this to make sure every watch is compatible with your app. One way to use this would be to set up an if statement:


if(mLowBitAmbient = true) { statement } public void onDraw(Canvas canvas, Rect bounds)

This is where the watch face is drawn onto the screen. Here you are able to call on the Paint objects and use the canvas class to rearrange everything how you want. You can also setup variables to add the date, time and battery information with just a few lines of code. This is also the area where you define what happens when the watch goes into ambient mode and what happens when it wakes up. Getting the battery information will require one extra line of code for it to work in our experience: Context context = getApplicationContext(); This will need to go just before Intent and the registerReceiver that get the battery information. Without this line of code we could not get the battery information to work properly.

The MainActivity in the mobile module is a lot simpler:


public class ApplicationTest extends ApplicationTestCase { public ApplicationTest() { super(Application.class); }

This is the whole program for a basic watch face, more files may be required depending on what you want to accomplish. One of the main reasons to have more programs would be add the weather to the watch face, which would require getting the weather from the weather service from the phone and sending that information to the watch.

Setting up the manifests

The chúng tôi for both modules will be very similar to each other. Each are setup just like a regular Android application. The mobile manifest will also include the wear module’s permissions as well as it’s own. If the permissions listed in the wear manifest and the wear permissions listed in the mobile manifest do not match, you will not be able to build a release apk. An example of each manifest is available in the SDK to use.

Android Virtual Device Manager Quirks

The Android Virtual Device Manager can be a great tool, but having a real watch to test your app can make a huge difference. In our experience developing Android Wear apps, the AVD does not always display the content correctly nor does it always communicate with the phone like an actual watch would. For example, when creating a watch face that uses images as hands, the AVD may position the hands slightly different than on the real thing. While the hands may appear centered on the AVD, they are off centered on the watch to either side. This is an easy fix. If it happens to you just adjust the coordinates of the hands in the program. Regarding connecting with the phone and retrieving information such as weather, the AVD seems to work better than the actual watch. So just because it works on the AVD doesn’t mean it will work on the watch. Keep this in mind if you just have access to the AVD.


Developing for Android Wear is relatively easy using the same tools you would use to develop for Android. Just remember that instead of one module there are two. One is for the part of the application that goes to the watch and the other module goes to the phone. Android Studio works very well when handling everything on the mobile side and watch side, however, some AVD quirks do not make this a perfect experience and you should check everything twice if possible.

Since Java is the most common language used for Android there are a lot of tutorials and guides on how to do most of what is required to make a simple Wear application. Google offers some great samples included in the SDK, these are a great place to start.

Google Extends Android To Wearables: Introducing Android Wear

Wearable computing is set to take off in a big way as the Internet giant Google on Tuesday introduced Android Wear, as previously promised.

Android Wear, as the name suggests, is meant to put Android on wearable devices such as smartwatches.

The company will be releasing soon the official Android Wear APIs to device vendors who want to put the power of Android in their health and fitness bands, smartwatches and other wearable gizmos.

Wearable devices driven by Android Wear include ‘OK, Google’ functionality and Android’s rich notification system. Moreover, they can show users timely information and suggestions akin to Google Now.

Perhaps the most interesting bit is the ability of Android Wear devices to relay your voice commands to other devices such as smartphones, tablets or Chrome devices. Starting today, programmers can download a Developer Preview to tailor their existing app notifications for watches powered by Android Wear.

The company said that first Android-powered wearables are coming later this year. Jump past the fold for more information and a pair of pretty good promotional videos…

Google says it’s partnered with fashion brands like the Fossil Group, hardware manufacturers such as Asus, HTC, LG, Motorola and Samsung and chip makers Broadcom, Imagination, Intel, Mediatek and Qualcomm to “bring you watches powered by Android Wear later this year”.

Here’s a quick video tour of Android Wear.

The video is pretty nicely done.

That being said, I must admit that I really can’t picture myself talking to my watch on the train. It makes for a nice video presentation, but I just don’t see people around me conversing with Siri in public.

Although Android Wear is starting with smartwatches, the project is conceived to go well beyond wrist-worn devices and should include health and fitness bands and other form factors.

Some of the highlights of Android Wear include, according to Google:

Useful information when you need it most – Android Wear shows you info and suggestions you need, right when you need them. The wide variety of Android applications means you’ll receive the latest posts and updates from your favorite social apps, chats from your preferred messaging apps, notifications from shopping, news and photography apps, and more.

Straight answers to spoken questions – Just say “Ok Google” to ask questions, like how many calories are in an avocado, what time your flight leaves, and the score of the game. Or say “Ok Google” to get stuff done, like calling a taxi, sending a text, making a restaurant reservation or setting an alarm.

The ability to better monitor your health and fitness – Hit your exercise goals with reminders and fitness summaries from Android Wear. Your favorite fitness apps can give you real-time speed, distance and time information on your wrist for your run, cycle or walk.

Your key to a multiscreen world – Android Wear lets you access and control other devices from your wrist. Just say “Ok Google” to fire up a music playlist on your phone, or cast your favorite movie to your TV. There’s a lot of possibilities here so we’re eager to see what developers build.

Developer should check out a new section focused on wearables on the Android website.

Google says a bunch of existing Android apps that support notifications should work well with Android Wear. The company will be soon releasing more developer resources and APIs soon.

LG has confirmed (via Engadget) that it is now working on an Android Wear smartwatch that should be released by this summer.

So, this is Google’s smartwatch project then.

Your move, Apple!

What are your initial thoughts on Android Wear?

Can Google replicate Android’s success in smartphones and tablets, only this time with Android-powered wearable devices?

How To Enable And Listen To Spotify Offline On Wear Os Android Smartwatches

Spotify has had a dedicated streaming app for Wear OS for years, allowing users to control the music that they’re listening on their smartphone or computer. Although wrist-enabled controls were convenient on some occasions, we still needed to carry around our smartphones or laptop to stream music from. This rendered the existence of the Spotify app on a watch almost useless when you don’t have your phone around like when you’re cooking, running, or doing activities that prevent you from taking your phone out of your pocket every single time.  

The streaming service is now solving this problem in the latest update that’s coming to Wear OS devices. This is possible thanks to a new feature – the ability to download Spotify tracks directly on your watch for offline playback. In this post, we’ll discuss how offline playback works with Spotify on Wear OS, how to make it work, and how to download content directly on your Wear OS smartwatch.

How does Offline Playback work on Spotify on Wear OS?

With the latest update, Spotify has given users the ability to download songs and podcasts on their smartwatches without needing to connect their smartphone or computer. Users can now store their favorite music and podcasts on their watch and listen to them offline when they’re not connected to a Wi-Fi network or their smartphone. Since Wear OS allows you to connect with a pair of Bluetooth headphones directly, you no longer need to have your phone with you when playing music or podcasts on Spotify. 

This can be helpful in situations when carrying a phone with you can be inconvenient or when you find it annoying to take it out of your pocket time and again. When you download albums, playlists, and podcasts with Spotify on your Wear OS device, you will be able to access it without needing to connect your watch to the internet for as long as you remove it from your watch. 

The new Wear OS-based feature comes just a couple of months after Spotify rolled out a similar feature for Apple Watch users for a true offline and phone-free experience. At the time of its release, the ability to download playlists, albums, or podcasts from Spotify was available on Apple Watch Series 3 or later, with watchOS 6.0+ with a cellular connection or Wi-Fi.

In order to get offline playback to work for Spotify on your Wear OS device, you need to make sure you have the following things sorted. 

Your smartwatch is running Wear OS 2.0 or higher

You should have the latest version of the Spotify app on Wear OS

Your watch is connected to the internet via Wi-Fi or Bluetooth (and your phone’s cellular data)

You should be a Spotify Premium member to download all tracks (Free tier users can only download podcasts)

When the Play Store opens up, scroll down on the screen on your watch and select the ‘My Apps’ option. 

If there is an update available for the Spotify app, it will be visible inside the ‘Updates available’ section. If the Spotify app is up to date, it should be listed under the ‘Recently updated’ section and you can access its new feature directly by opening the app.

How to Download Songs/Podcasts for Offline Playback on Spotify on Wear OS

Once you’ve fulfilled all of the above requirements to use Spotify’s new Offline Playback feature on Wear OS, you can get started by opening the Spotify app on your watch. 

When you launch Spotify on your watch, you should see the main playback screen load up. Since you need to access the tracks to play and download on your watch, swipe from right to left on this screen to bring up the Spotify Home Screen. 

Before you can download a track inside Spotify, you need to know that you will need to download full albums or songs from a playlist that’s recommended to you inside the Home Screen. You cannot download single tracks but you can save individual episodes from a podcast on your watch. Also, since the Spotify app on Wear OS doesn’t let you search for tracks yourself, you can only download those tracks that are listed inside the Home Screen. 

Downloading playlists and albums

On the Home Screen, select the playlist, or album you want to download. 

Spotify will now start downing the album or playlist you selected and you should be able to see the number of tracks that will be downloaded in the process. 

You will now see the progress of your download on the screen.

When the download is complete, you will be able to play it directly from your watch on a connected device without using your phone. 

Downloading podcasts

On the Home Screen, select the podcasts you want to download. 

Once the selected episode appears on the screen, tap on the ‘Download to Watch’ option under the episode title to start downloading it. 

You will now be able to see the progress of the download indicated by a green circle on the left side of the ‘Downloading’ text.

How to Access your Downloaded Tracks on Spotify

Spotify offers a neat way to check all the tracks you have downloaded onto your watch. You can access all of the downloaded content by first opening the Spotify app and then swiping from left to right on the playback screen. 

If you haven’t downloaded anything using Spotify on your watch, this section will remain empty.  

If you downloaded a playlist, album, or podcast, it will show up on the next ‘Downloading complete’ screen. To play the tracks that you have downloaded, tap on your selection.

Inside the album or playlist, tap on any track you want to play on your watch.

If it’s a podcast you’re playing, select the episode you have downloaded and tap on the Play icon at the top on the right side of the episode title.

If you haven’t played Spotify from your watch yet, tap on the ‘This watch’ option under ‘Select a device’ on the next screen. 

You’ll now see your watch’s Bluetooth settings screen load up. On this screen, make sure the ‘Bluetooth’ toggle is enabled. Now, tap on the wireless earphones that you want to connect to. 

Once the earphones are connected, you can go back to the Spotify app to play your downloaded track. 

How to Check if a Track is available for Offline Playback

We’ve explained above the easiest way to access your downloaded tracks on Spotify but is there a way you can check if a playlist, album, or podcast you’re browsing already has something you’ve downloaded previously? Yes, there’s a clear way to see if a track has already been downloaded on a smartphone. 

Tracks or podcasts that have been downloaded from a certain album/playlist can also be visible in other playlists. If you see a little green Download icon (the one with a downward-facing arrow) adjacent to a track, then it means that this song or episode has already been saved onto your watch. 

How to Remove Downloaded Tracks from Spotify on Wear OS

On the next screen, select the playlist, album, or podcast you want to delete from your watch. 

The selected tracks will now be removed from the ‘Downloading complete’ screen and will be deleted from your watch’s storage. You can remove downloaded content from Spotify to save space for other tracks or episodes to download at a later time. 

Offline Playback on Spotify: Limitations?

As convenient as it sounds, Spotify’s new Offline Playback functionality comes with a few caveats that you should know before you try out the feature yourself. 

First things first, the ability to download a playlist, album, or podcast on Spotify’s Wear OS app is only accessible to Spotify Premium subscribers. Premium users can download any number of tracks and episodes on their watch as long as the watch has the storage space for it. However, Spotify’s free users won’t be able to download playlists or albums on their watches.

Instead, users of Spotify’s Free tier can only download podcasts on their Wear OS device. If you wish to play songs on Spotify with a free subscription, you’ll have to make things do by streaming your tracks in Shuffle Mode with an active internet connection. 

Secondly, Spotify only lets you download tracks that are bundled inside an album or a playlist that’s available inside the app’s Home Screen. You won’t be able to store individual tracks but will have to download all the songs from a particular album or playlist, which might be annoying when you only like a handful of songs from one album playlist. 

This is not aided by the fact that you cannot search for songs you want to download directly from the Spotify app on Wear OS. Since Spotify’s home screen only shows recommended content for you to listen to based on your usage history, the options to personalize what you want to download onto your watch is minimum. At the moment, Spotify only shows you playlists based on your listening habit, podcasts and shows you frequently play, your top mixes, and more playlists and podcasts that you may like. 

That’s all you need to know about using Offline Playback on Spotify on Wear OS.


Tesla Could Be Developing Its Own Apple

To recall, speculations surrounding the app store began making the rounds online back in December. Apparently, the rollout of the latest version 11 update of the in-car interface for Tesla cars sparked this rumor. To recall, the popular EV (electric vehicle) maker had even added a customizable icon bar at the touchscreen’s bottom at the time. Last year, CleanTechnica suggested that Tesla would eventually launch an app store in a bid to keep Tesla car owners occupied as their vehicles drive themselves around.

Tesla App Store Could Be In The Works

Some reports indicated that Musk would unveil the app initiative in January, at Tesla’s latest earnings call. However, the 50-year-old business magnate did not shed light on the company’s rumored plan to launch an app store. Nevertheless, a recent tweet from Tesla investor, Sawyer Merritt seems to have reignited rumors around the EV maker’s plan to develop an app store. Merritt, who is reportedly “in the know,” took to Twitter on Sunday to hint at the imminent arrival of the aforesaid app store for Tesla vehicles.

Elon Musk Is Still Mum On Tesla’s Plan To Launch An App Store

Further in the tweet, Teslascope notes that Musk was expected to shed more light on the App Store at the earnings call. However, the SpaceX founder did mention that 2023 would be the year of “software.” Moreover, Teslascope notes that since the app store was not mentioned at the recently concluded earnings call, there is a possibility that its launch could’ve been pushed back. Nevertheless, the worldwide drivers’ platform claims that the app store has been in development since the debut of V11 UI with the radically overhauled Model S/X.

However, it is worth mentioning here that TheDriven did not find Musk calling 2023 will be the “year of software” in his tweet, or anywhere else. Nevertheless, earlier this month, Musk tweeted that Tesla is not only a software but also a hardware company, in the car as well as in the factory. He noted that a lot of people fail to understand that.

What To Expect?

If Tesla introduces an app store, it will catapult the already pioneering electric brand to skyrocketing popularity. Aside from that, offering an app store would serve as another revenue stream. Moreover, it will be an addition to a slew of other products such as self-driving subscriptions. Moreover, Musk had teased an app store for Tesla on a conference call. He notes that once cars become fully self-driving, drivers are likely to look for some sort of entertainment, as well as productivity options in the cars. He added that via Tesla’s “app store or whatever,” drivers want to work and play games. Furthermore, he noted that they will be adding some games.

Moreover, Volvo and Polestar feature Android Automotive which is integrated into their EVs. As a result, drivers can access vehicle-specific apps through Google Play Store. However, Tesla has already turned down the idea of integrating Android Auto and Car Play into its electric cars. In other words, Tesla may have been gearing up its launch its app store venture for a long time.

Python has a wide range of libraries, in-built tools, and modules for different automation tasks. For example, the Pandas library can be used to automate data cleaning and data wrangling tasks, while the PyAutoGUI library can be used for GUI automation.

What is Python RPA?

Python is a popular language for RPA because of its simplicity, flexibility, and wide range of libraries and frameworks that make it easy to automate complex workflows. Python RPA typically involves the use of libraries, such as PyAutoGUI, allowing Python to simulate user input and interact with graphical user interfaces (GUIs). Another example could be BeautifulSoup, which is used for automated, web page scraping and data extraction.

What are the use cases of Python RPA? 1. Creating RPA automation processes

Users can use Python packages to automate repetitive, time consuming tasks. For example, Python scripts can be used for doing web pages, creating customized bots from scratch for scraping a web page or manipulating elements in a file. Alternatively, Python’s data visualization libraries, such as Matplotlib and Seaborn, enable users to present  large amounts of data in the form of charts and graphs.

2. Expanding RPA use cases

Some robotic process automation tools provide APIs that allow developers to access and integrate their Python code with the RPA software. This enables the bot to interact with external desktop applications to quickly automate complex, repeated tasks, such as querying a database, using files and accessing an API.

3. RPA analytics

Python can be used for data analysis and visualization in RPA processes for better project management. For example, Python scripts can be used to analyze both performance metrics human error, or generate reports on RPA process efficiency.

4. Machine learning

Python’s machine learning libraries, such as Scikit-Learn and TensorFlow, can be used to train bots to perform more complex tasks, such important tasks such as image recognition or natural language processing.

What are the benefits of Python RPA? 1. Easy to Learn and Use
