download and install Android Studio

Are you starting to develop your own Android apps? So you'll need Android Studio, the development environment created by Google. Follow our tutorial to learn how to download and install it.

Are you tired of being a user and want to go to the other side of the mirror to create your first applications? Have you already started learning a compatible programming language?

So all you have to do is get started. For this, you will necessarily need Android Studio. But what is it, and how can you install it? We will guide you.

What is Android Studio?

Android Studio is the development environment directly provided by Google to create applications for its mobile operating system. A development environment is software that immediately provides all the tools you need to program, compile, and test your application before launching.

Thus, Android Studio provides an improved text editor to allow you to create your code and access all Google APIs, but also an integrated compiler to be able to create your final application, and all it takes to test this application by through an emulator or by sending it directly to your mobile phone.

Android Studio allows you to test everything on any device in the Android universe, from the many types of smartphones available to Wear OS or Android TV. Once your project is complete and tested, you can send it directly to Google for publication on the Play Store.

How to install Android Studio

Install Android Studio on Windows

The procedure is very simple. First you need to download the latest version of Android Studio from the Google site. This is a simple .exe like any application.

When installing, do not touch the default settings. At the end of this one, you can import a previously made configuration from your development environment. On a first installation, select "do not import". Let yourself be guided, and you will soon be ready to embark on Android development.

Install Android Studio on Mac

First download Android Studio as a .dmg file from the Google site. Launch it once, then drag Android Studio into your Applications folder.

The configuration is then the same as for Windows.

Install Android Studio on Linux

On Linux, you will first have to download the dedicated .zip file from the Google site. Uncompress the file in a suitable place, such as / usr / local / or / opt / if you want the application to be shared locally with other users.

To launch Android Studio, launch the terminal, move to the / android-studio / bin / directory and run studio.sh.

On a 64-bit Ubuntu machine, you will also have additional libraries. To install them, run the following command:

"Sudo apt-get install libc6: i386 libncurses5: i386 libstdc ++ 6: i386 lib32z1 libbz2-1.0: i386"

On 64-bit Fedora, the command is this:

"Sudo yum install zlib.i686 ncurses-libs.i686bzip2-libs.i686"

So you are ready to code your first application!

Android 10 Q will allow you to retouch the blur of your photos in third-party applications

Among the new features announced by Google on Android 10 Q, there is one that should particularly appeal to photographers. It will be possible to modify the background blur from one application to another.

For the last two years, smartphone manufacturers have been multiplying software and hardware solutions to detect the depth of their photos. It can be a second sensor only to calculate the depth, as on the OnePlus 6T, or a particularly effective sensor through the image processing, as on the Google Pixel 3.

Nevertheless, one of the main concerns with these background blur effects was their incompatibility from one application to another. With the exception of Google Photos or Facebook, apps were unable to change this blur effect, either to increase, soften, or change the focus on another subject in the frame.

Possible retouching on third-party applications

It must be said that the images extracted from these photo applications are simple JPG files that can not integrate more than just visual data. It is in this context that Google has announced the arrival, with Android 10 Q, "XMP metadata related to the elements of depth, with a map of the depth integrated in the same document for the devices that support it". In concrete terms, this means that the depth data in an image can be integrated directly into the file.

We can imagine that third-party applications will take advantage of this to modify the depth of field, the background blur, or to add color elements depending on the depth of this or that element. A feature that could for example be taken by applications allowing image editing such as Instagram, Photoshop Express or Snapseed Google.

However, during this conference, we did not see any trace of the Huawei P30 Lite yet in the pipes and already certified by the TENAA. The manufacturer has made no statement about this ... but the same can not be said of a Filipino reseller, Abenson, who has already published a full page on this light version of Huawei's flagships, highlighting its strengths , especially on the photo and selfies.

Abenson offers indeed the Huawei P30 Lite pre-order today even though the brand itself has not yet officially communicated about it.

A good opportunity to discover the features of the Huawei P30 Lite:

Inside a central computer unit

Whether you have a desktop computer or a laptop, your computer always consists of a CPU. Indeed, a CPU is the part that allows your computer to function properly.

If you have a laptop, the CPU is located inside the computer since you only have one block. In the case of a desktop computer, the CPU will be a block completely separate from the screen, the keyboard and the mouse. Indeed, these will be peripherals of the central unit which will be the heart of the computer. A computer, laptop or desktop, can only work in the presence of the central unit.

A central unit is composed of several elements that are mandatory. These elements are the processor which is a computer chip playing the role of computer brain, the motherboard which is a large circuit board with connection ports and which plays the role of nervous system of the computer, the memory which is also called RAM and which allows the computer to start and store data, the graphics card which is also called video card allows the display of the content on the screen of the computer, the sound card which is also called audio card and which manages the sound of the computer, the hard drive that allows the computer to store the data and keep them even when you turn off your computer and the DVD player which can be a simple player , a single burner or a burner drive allowing you to play DVDs and CDs.

In addition to these elements, other elements are also connected to the central unit. These are called devices. Since the CPU is the centerpiece of a computer, it must be properly protected. Thus, a central unit is protected by a plastic or metal case whose role is to protect the various components of the central unit against electromagnetic waves in addition to acting as sound insulation. The protective case of the CPU is often called the "tower" for a desktop. When you buy a desktop computer, you have the choice between three types of cases namely the big tower case, the middle tower and the mini tower. Whatever type of enclosure you choose, it must be equipped with a power supply.

What is the best purchase period for a laptop ?

In today's world, with the advancement of digital and advanced technology, it is helpful not to say vital to have a laptop. This machine is useful in everything we do. But how to get one at a cheaper price?

Price according to seasonality

Depending on the time of year, purchase prices for laptops may vary. Computer balances often take place during the end of August and September. During this period consumers return from holidays, children go back to school, taxes arrive, all with a considerable outflow of money. The distributors then decided to market low-cost, specially manufactured laptop models. But there is also another moment of computer payoff in December. The month of December is the holiday season but also the release of new devices designed for these holidays. In this sense, laptops that are in stock in stores will be promoted to give room for new products.

What budget do you anticipate?

It is not always easy to answer this question effectively since the purchase price of a laptop varies according to several parameters to take into account. But it takes at least 250 euros and 500 euros maximum to have a notebook ultraportable range during sales periods. But at the same price, we can have hybrids that can turn into a tablet or laptop, only, at that price, they are fragile products, not very powerful or super ergonomic. For a minimum price of 1000 euros and 1500 euros maximum, it is possible to have quality hybrid laptops. At the same price, on the other hand, you can have a small desktop PC with small boxes but you have to add a screen and a keyboard. For Mac brand laptops, they are quite expensive, so better to look for opportunities.

How do computer programming languages work ?

To work, a computer program needs computer software. These are developed from precise languages that describe the set of consecutive actions that a computer must perform. Based on precise algorithms, it is not always easy to know how it works. Here is a brief, helpful summary.

Computer programming languages allow software and programs to communicate with machines. They are the ones who give orders to tell the machine how to respond to a particular request from the user. This is a basic approach and computer programming is much more complex than that. The programming language is thus classified into two major programming families: the imperative language and the functional language.

The difference between his two families results in the way instructions are given and processed by the machine. In the imperative language, the program follows a series of instructions that the program executes. They are subject to a condition that if not fulfilled prevents its operation. The functional language consists of a program built by functions. The functions fit together. We speak of recursion when the function is called itself.

Computer language is also classified into two general categories. We thus find the interpreted languages and the compiled languages. The difference lies mainly in the way the communication is handled. The interpreted language thus needs an auxiliary program that will translate the given instructions. Languages such as MATLAB, PHP to develop websites or Prolog for artificial intelligence. We speak of compiled language when the file is completely autonomous.

For this he needs a compiler that can translate a program once that can work anywhere. The resulting file is an executable! This type of file is very convenient since it can only be modified by one owner. Anyone who tries to modify it must compile the file again. Among the most common computer languages compiled, there are the C, C ++ that are used in programming video games or applications for example.

There are also intermediate computer languages that combine both the interpreted language and the compiled language. In this category we find languages like Python, Java or LISP ...
