android 11

 

Google officially announced the firs Android 11 beta yesterday. This means the end of the developer preview cycle and the beginning of the beta cycle, which is pre-requisite software before the stable launch. Usually, Google has a big unveiling event to announce something like that. However, the COVID-19 situation is changing in the tech industry just like it is changing the whole world. Instead of delaying it, Google decided to go for an online-only event instead, but then those plans were also squashed by the ongoing protests of the black community to the death of George.

 

Now, Google simply launched the Android 11 beta along with some informational videos and content. The company says that this will allow people to consume at your own pace when the time is right for you. It's not as glorious as having a big Google event, but it is the best Company could come in amid several bad conditions.

 

So, what's new in Android 11?

So far, there doesn't appear to be too much difference between the previous Android 11 DP4 and today's Android 11 beta. We are currently getting the beta installed on our own devices and will be able to investigate any new features and goodies Google may have introduced. For now, though, all we have to go on is Google's announcement, and there's nothing there that we haven't already seen.

 

You can check out our running roundup of the newest Android 11 features on the way, but the biggest changes will be easier access to conversation notifications, enhanced user privacy and security options, and better control over the other devices you usually connect to your phone.

 

Now, the bad news is you can't install it on your non-pixel device yet. Unfortunately, the new Android 11 beta isn't yet compatible with any other device than Google Pixel. The new beta will work on the most recent pixel device only. This is a major shift from the tradition where we see dozens of other phones offer beta support for Android beta versions.

 


android

 

First of all, it should be mentioned that modern programmers write applications not for a specific phone, but for a specific mobile operating system. And there are far fewer such operating systems than mobile phone models. Most often, the latest versions of iOS (for smartphones from Apple), Windows Phone (for smartphones of the Lumia series), and Android are used. Android is currently rated as the most popular mobile operating system. If you go to the catalog, for example, the Yandex. Market search engine, which contains smartphones from leading manufacturers (Acer, Fly, LG, Samsung, Sony, HTC, etc.), then with Android OS of all versions (from 1.5 to 5.0) you will find at least 1,500 offers, with Windows Phone - only 50, and with iOS - no more than 20. Android is usually installed on smartphones of different classes - from ‘budget' models to expensive devices. 

Due to the high popularity of Android smartphones, developers have to work actively to provide customers with new functions and applications. Therefore, sometimes programmers need programming homework help online. In other cases, specialists make mistakes during coding. You should make sure you hire android developers that meet the qualifications. In our article, we will tell you in detail about the common mistakes in Android programming.

Mistakes in Android Programming

As it is known, errors in the software are all possible discrepancies between the characteristics of its demonstrated quality and formulated or those that meet the requirements and expectations of users. Since when developing programs, the programmer must first understand the problem, then come up with its solution and encode it as a program, we can identify three main sources of mistakes

  • Misunderstanding of tasks. Software developers do not always understand what exactly needs to be completed. The analysis of the subject area is usually carried out to prevent misunderstanding of the tasks of the software system

  • The incorrect solution of tasks. Maintaining constant contact with customers and users, providing them with the necessary information about selected solutions and their prototypes can help in choosing the right solution

 

  • Incorrect porting of decisions into code. The correct representation of decisions in the code can be hindered by both common mistakes and forgetfulness of the programmer or his unwillingness to abandon the usual techniques that do not allow to accurately record the decision

Typical Mistakes

As for some types of common mistakes that a developer may make, they can be as follows:

  1. The wrong algorithm (for example, there are various methods, in particular, Gauss's method, Seidel's method, run method, etc. for numerical solution of systems of linear algebraic equations These methods are similar when fulfilling certain (own for each method) conditions that are imposed on the system of equations, and this fact must be taken into account when choosing a method in each case)
  2. Errors of analysis (incorrect programming of the correct algorithm)
  3. Semantic errors (for example, an operator does not actually act quite exactly, or not at all as the programmer predicts). In this case, the program works but works incorrectly. The search for these errors occurs by means of logical analysis of the program and its testing
  4. Errors in performing operations (loss of accuracy, going beyond the data type, etc.)
  5. Data mistakes (symbolic instead of numerical, etc.)
  6. Indexing with going beyond the array, i.e. the use as elements of the array of variables that are outside it
  7. Unforeseen special cases of input-output - for example, when the end-of-file signal is not processed

There are different types of mistakes, depending on what stage of software development the error was detected:

  • Syntactic mistakes are usually allocated by an assembler and prevent further compilation. The absence or inconsistency of open and closed parentheses can serve as an example here. Syntactic mistakes often arise in writing constructions of programming language (numbers, variables, functions, expressions, operators, labels, subroutines); these are errors related to the incorrect content of actions and the use of invalid values

  • Compiler warnings. The application of an uninitialized variable can serve as an example in this case. The compiler may notice that the developer is doing something incorrectly and report about it, but the programmer himself decides to pay attention to the message or not
  • Runtime mistakes. These errors occur during program operation. This usually happens when a program tries to perform an invalid operation. An example of such an invalid operation is division by zero, semantic errors (subtraction of variables instead of addition or segmentation error)

Ways to Eliminate Errors

Two operations are usually used in order to eliminate errors:

  1. Debugging - elimination of syntactic and other elementary errors in programs
  2. Testing - checking the correctness of the program on pre-prepared tests based on the already known exact result

Thus, in this article, we told you about common mistakes in Android programming. We hope this information was useful for you.

 


Android Apps

 

Developers released some great apps for Android users in the year 2019. These releases span on a multitude of categories. In this article, we will see the best 5 Android apps from 2019.

 

Adobe Premiere Rush

 

It is a video editor by Adobe. The app boasts a near-professional experience with full video editing capabilities with a multi-track timeline. It has various templates for mobile videos. It doesn't have everything like the desktop version of Premiere Pro, but this app is enough for the mobile video needs.

 

Calendar Widget by Home Agenda

 

The app has an extensive list of features, themes, and layouts, to group events together and various other customization options. The design of the app and widget is super clean and works in over half a dozen languages.


Mint Browser


The mint browser is a good mobile browser. It hits all the basic requirements like low storage needs, night mode, incognito mode. The data saver mode just blocks ads and restricts image loads in articles. It isn't competing with Google Chrome or Firefox but if you are looking for something lightweight and functional, this is a great app.


Spark Mail


The app is free for right now. It does the basic email, snooze email, schedule email, and reminders just like inbox by Gmail. Some other features include pinning emails, undo sent email, and a decent email search. It can also work with other email clients like Gmail or Outlook.


Xbox Game Streaming


Google launched Stadia this year, and its major rivals choose mobile streaming. Microsoft and Stream launched its game streaming apps this year. Both apps do almost the same thing. You can play your PC games or Xbox games on your device. Unlike Stadia, these apps are using your existing hardware to play the game and your local area network to play the games on your mobile phone. These could be excellent alternatives to Google Stadia.


android-raspoberry-pi


The Raspberry Pi is a fantastic tool for learning how to code and how a microcontroller works. The most difficult part of using the Pi is its initial OS setup, but even this should be pretty simple if you follow the steps below.


Register Emteria.OS

 

The first thing that you need to do is register an account on emteria.com. On the homepage, you should see the button to register at the top. The registration form is the standard fare, asking for your name, email address, etc.


Once you have filled out the registration form, you then need to wait for the confirmation email so you can confirm your email address and log in properly.


Get the Installer

 

Once you are registered and logged in to the website, you can then download the installer that you need to install Android on your Raspberry Pi. The installer will burn your copy of the operating system onto a micro SD card. It is worth checking beforehand that the MicroSD card you plan to use is supported. While conflict is rare, it is safer to stick to an established brand like SanDisk who are all but guaranteed to work properly.


Flash Your SD Card

 

Open up the installer and then enter your login details for the operating system. You then need to select the type of Raspberry Pi that you have, as well as your intended installation location. For your purposes, your installation location will be the microSD card that you have prepared.


Using F-Droid

 

Once the SD card has been flashed and the operating system installed, you then need to get some apps on there. You can sideload apps onto the Raspberry Pi from your computer, but this is much less convenient than just downloading from an app store as you would on your phone. Unfortunately, because this build of Android does not come from Google, it does not have access to the Google Play store.


Lucky for us, there is an alternative called F-droid. F-droid is a third-party app store for Android that will enable you to download apps in just the same way that you do on a regular Android device.


You will find F-Droid in the apps menu, and there should be an icon on your home screen. When you first launch F-Droid, it will take some time to download all of the updates and repositories. Be patient, as once this is over, you are ready to start downloading apps directly to your device.


Taking It Further

 

Once you have got your Pi set up and you have had some time to get used to it, you may well feel ready to dig a little deeper. If you find that the Raspberry Pi is an exciting new frontier for you, you will almost certainly be interested in the world of PCB design more generally.


The Pi is a fantastic tool for anyone who wants to learn how to code and the nature of the relationship between software and hardware. Learning about PCBs will help you to understand how microcontrollers like the Raspberry Pi are designed and work. For example, Altium is a developer of PCB design software and their website is full of useful articles like this one about how a touch sensor button works.


Installing Android onto your Pi should be a simple and straightforward process. Once you are set up, you can begin exploring more advanced Raspberry Pi projects.

 



west-africa-android

 

Look around you at the phones that West Africans are using today. Gone are the Nokia of yesteryear. Now, everyone seems to be using smartphones, and almost always Android.

 

Why is Android so popular in West Africa? Why hasn't Apple cornered the biggest chunk of the smartphone market, like in Europe and North America? 

 

We're here to find out.

 

We want to investigate exactly why Android is so popular among everyday Africans. What caused the market dominance of Android phones?

 

Wondering why everyone is using Android? Then you'll need to read on.

 

They are Cheap

 

First and foremost, Android smartphones are a cheap solution to a modern problem. If you want to get ahead in the modern world, being constantly connected is massively important.

 

Whether you're a jobseeker, a businessman, or an engineer, being available for contact is paramount. 

 

When the iPhone launched, it was far too expensive for most people to buy. Despite recently cut production costs, the iPhone is still too expensive for a large chunk of the population.

 

If you want, you can buy a Leagoo phone for just under 50 USD. That's affordable, even on a low wage. Due to lower wages, many people in West Africa said they consider price first when buying a smartphone.

 

It is Open Source

 

If you want to tinker with the Android operating system, then you can happily do so. Customization of the OS, creation of apps, and uploading these apps to Google Play, are all easier on Android than iOS. 

 

This encourages local programmers to work on Android, rather than iOS, as they don't have to pay licensing fees. 

 

The software market in West Africa is large, and Android makes a natural partner for this. Just as Linux has a lot to offer African developers, so does Android. It's a way to sharpen skills, make some money, and potentially, become rich.

 

Androids Often Have Better Battery Life

 

If you live in area that doesn't always have electricity, battery life is crucial. Androids best iPhones here. 

 

While iPhones are stricter in what apps can run in the background, Android phones do mostly have better battery life than their Apple rivals. They also often come bundled with fast chargers, which allow for much quicker charging times.

 

In rural areas, battery life is perhaps the most important feature for staying connected. If that is what you need, then you'll need an Android phone. The iPhone's shorter battery life is fine for the city, but that's all.

 

Androids Offer Far Better Navigation as Standard

 

If you want to use your phone as a GPS, chances are, you'll want to use Google Maps. While Apple Maps is improving all the time, it still lags behind Google Maps.

 

For example, do you want to use your navigation app to get directions for public transport? If you're on Apple Maps, you're out of luck. The app only offers detailed public transit directions in 17 countries. 

 

On Google Maps, you get access to thousands of different cities and towns' transit networks, at the touch of a button.

 

While you can install Google Maps on iPhone, it is an irritating additional step. It is also beyond the reach of some users, particularly older people. For ease of use, Android absolutely dominates the smartphone market when it comes to navigation.

 

A Greater Choice of Apps

 

The open-source software that underpins Android allows for an abundance of apps. There are around 2.47 million apps on Google Play. In contrast, the App Store offers just 1.8 million.

 

While the App Store does have a lot to offer consumers, it's lacking in hyper-local apps. Many West African businesses offer apps of their own, as do some cities, such as Lagos. 

 

The ease of Android development promotes a healthier business environment, with greater choice for the consumer. 

 

This greater choice is immediately evident when comparing search results from the stores. Apple's own apps often appear first in search results, which some have seen as an unfair advantage. By contrast, searching for software on Google Play gives you a much larger immediate selection to choose from.

 

Better Hardware Connectivity

 

When Apple did away with the headphone jack, there was uproar, and justifiably so. 

 

Countless millions of people use wired headphones every single day to enjoy podcasts and music. Those who have bought iPhones since the iPhone 7 have had to spend far more money on hardware than Android users.

 

If you want, you can buy a dirt cheap headset, and plug it into an Android phone. You don't have that choice with an iPhone. 

 

It's not only headphone jacks that are symbolic of this problem with Apple's design philosophy. It's lightning, too.

 

Lightning cables are expensive and break easily. They're also only able to be used with Apple products. 

 

The latest Androids use USB-C, which offers fast data transfer and charging, but can be widely used on a huge range of hardware. The cables are far more common and cheap to purchase. It's a much more user-friendly experience.

 

The Android Smartphone Market Offers Far Greater Choice

 

You cannot even begin to count the number of different Android phones on the market today. From ultra-cheap phones to the latest Samsung phones, there are thousands of different devices. There are just three iPhone 11 models. 

 

Whatever you need an Android phone for, you can find a model that fits those needs. You don't need to shell out for superfluous features you don't need. You don't have to go with a model because it's the only one available.

 

Instead, you can choose from a dizzying range at your local phone store. You're in control, from the very beginning. 

 

Final Thoughts

 

Android phones dominate the smartphone market in West Africa for three key reasons.

 

One, they offer cheap access to the latest technology. Two, they're rich with customization options. And three, because they are easy to use. 

 

If Apple truly wish to catch up with Android in West Africa, they need to embrace this trio of factors.

 

However, we doubt that you're going to see a budget iPhone on sale in the near future.
