This article will help all beginners and owners of Android devices get acquainted with SDK. You will learn how to install android sdk. Why is this needed: firstly, for hacking, secondly, to access the system part of the firmware and its subsequent change, and thirdly, to obtain root rights.
There is a tool in the SDK ADB (Android Debug Bridge) Debugging Bridge for Android or another interface for debugging Android, with it you can:

This manifest must be in the root directory of every application. Individual actions and settings, permissions and application settings such as icon, etc. are listed here. He has a detailed understanding of everything that is needed as a developer. Here we can set many filters, such as what activity we want to list, what application, what messages to write, etc. With this tool it's easy to find what exactly went wrong. We will find out which line is the error.

We find the item environment variables and find the item Path, click edit and without deleting anything, add your path separated by a semicolon C:\adt-bundle-windows\platform-tools(see picture). Click OK.

You can also download and install. Let's go to the official library website, go to the "Download" section and click "Download Installer". Finally, we have everything loaded, now there is only update and progress. Beginners fill out the boxes, as well as in the picture, advanced ones can be filled out according to themselves.

We'll get to know the library by creating a simple game in which we won't use the extension. The second to last thing should be to successfully develop our design base. And this will be the last one for today. The project was imported by us and we see that it consists of three directories.

Now let’s check if everything is working: go to Start, launch the command line (preferably as an administrator for Windows Vista/7) and enter the adb command and get the following.

Result

If you received it, then everything works great.

ADB Commands

Here is a list of useful commands:
adb devices - View a list of devices that are already connected to the computer
adb wait-for-device - Wait for the device to connect
adb get-serialno - View device serial number
adb logcat - See what's happening inside the device
adb logcat > c:\logcat.txt - The command will save all changes to a file
filters for logcat
V - Verbose (lowest priority, default mode)
D - Debug (debugging)
I - Info
W - Warning
E - Error
F - Fatal (critical error)
S - Silent (highest priority, silent mode, do not output anything)
Example adb logcat *:W - Display only system error messages
adb logcat [-b ] - Displays system buffer information
radio - View the buffer containing messages from the radio/telephony module.
events - View a buffer containing messages of related events.
main - View the main log buffer (default)
Example adb logcat -b radio
adb reboot - Reboot the device.
adb reboot recovery - Reboot the device into recovery mode.
adb reboot bootloader - Reboot into bootloader mode.
adb shell cat /proc/mtd - View information about the “partitions” of the device’s memory.
adb shell df - View information about partitions and free resources.
adb push - Copy a file to the device.
adb pull - Copy a file to your computer.
adb install [-l] [-r] [-s] - installing the application
Example adb install from:/adb/app/autostarts.apk Install the autostarts.apk file located in the /adb/app/ folder on the disk with:
filters
-l Block the application.
-r Reinstall the application, saving the data.
-s Install the application to the memory card.
adb uninstall - Uninstalling an application.
Example adb uninstall autostarts.apk

We have to lay the foundation of our game, if you see the same thing as the image, you're totally cool and everything works as it should. The Czechs are desperately slow. As far as advanced compatibility is concerned, everything will work, but not necessarily follow the trends. Brew coffee or tea because it will take a long time.

Using virtual devices

If not, download and install it first. You must enable debugging directly on your phone or tablet. In the Name field, enter what you want your virtual device to be named. You will open a window that is worth your attention. An interesting one is the "Scale" option for actual size, which allows you to adjust the size of your phone display and the softness of your laptop display. The result is that you can display an 800px portrait on a laptop screen with a 768px portrait, and part of it still occupies different stripes.

Thanks to the Android SDK, you can open any Android application on your computer. For example, you can play Froot Ninja or Talking Tom on your work system. This program will be relevant for owners of mobile devices of this popular platform, software developers, or those who are planning to purchase a smartphone on Android OS. This utility can be used to select the necessary applications for your phone, however, the process of installing them on your computer is quite complicated. Let's try to download Android SDK for free and install its new version on your computer.

If everything worked out so well, what would you have planned? Enter a project name in the Project Title and click Next. The package name must contain the name of your application package. Create the action you want to test and don't change the name. What does this mean later?

Then click "Finish" and the application will be created. Double click on it and browse through the many forms and several tabs below. Don't worry, we will explain everything in other works. You'll get about 13 lines of source code for something obscure and a bit unknown. If you have a properly connected phone, the app will download to it.

Possibilities:

emulation of mobile applications;
selecting the desired Android device to display applications;
installation of different versions of Android OS;
choice of interface design.

Principle of operation:

The program interface looks like a mobile device. The main function of the Android SDK is emulation of applications for phones with the Android platform. When using the program, many users may experience problems during installation of applications. This utility will be useful for software developers for smartphones; it allows you to see the results of your work. At the stage of installing the program, you need to select the versions of Android OS required for installation. After that, you can add the necessary applications to the program to test and view them.

If not, you'll see a window where you choose which device runs the app. We'll explain all this next time, show you how to launch another from one activity and how to use some view. If you don't know any advice, don't be afraid to ask in the comments. I don't like the translation of the source at all. Writing resources is so much English. If the username associated with your Application includes a company name or brand, you must either authorize that company to use the company name or brand in your username or change your username to remove the company name or brand. Your application meets the application requirements. You are solely responsible for all aspects of the development and use of your Application, including related documentation, user assistance, support and warranty.

Responsibility for use.

Everything we do on Android using Java depends on the Android SDK - if we create an application for a specific version, for example, for Android Nougat, then we must have the appropriate SDK tools installed. This must be taken into account during development.

Let's open Android Studio. By default, if we run the program for the first time, then some initial menu opens to us. At the very bottom of the program’s start screen, find the “Configure” button and click on it:

For a more detailed view of all components for each platform, click on the Show Package Details link at the bottom of the window.

Here we can see in detail which packages are installed for each platform. All components are grouped by a specific SDK version, for example, Android API 27, Android 8.0 (Oreo), Android 7.1.1 (Nougat) and so on. Each SDK version actually represents a specific version or subversion of the Android OS. But each version of the SDK includes a wide range of components, including tools for development for TVs, smart watches, etc. Not all of these tools may be needed, so there is no point in installing all versions of the SDK completely.

In this case, we will be primarily interested in the item Android SDK Platform. Android SDK Platform contains all the main functionality that is used during development. This item can be selected for all those platforms for which we are going to compile the application. In particular, I recommend choosing the latest platforms - Android 8.0/7.1, as well as those that will be used as minimal platforms, for example, Android 5.0 / 5.1.

In addition to the SDK Platform, each platform, as a rule, contains a number of components that are intended for testing the application on an emulator:

Android TV Intel x86 Atom System Image

Android Wear Intel x86 Atom System Image

For earlier platforms, the list of components may vary.

If you do not plan to use an emulator, then these components are not so important. And vice versa, if testing will take place on an emulator, then you should install a system image for this Google APIs Intel x86 Atom System Image or Google Play Intel x86 Atom System Image.

Here, the most important packages for us are:

Android Support Repository

Android Support Library

Google Play Services

Google Repository

Google USB Driver

These packages install android repositories and google play services. In addition, if you want to use a Google smartphone - Nexus 5/5X and 6/6P or Google Pixel - to test applications, then you must install the Google Usb Driver package, which provides a driver for working with these smartphones. If you intend to use a smartphone from another manufacturer, then in this case you will need to install a USB driver directly from this manufacturer. As a rule, when you connect a smartphone, the system itself tries to install the driver.

If you plan to use an emulator, you should also install the package Intel x86 Emulator Accelerator (HAXM installer).

And if during the development or testing process problems arise with some versions of the Android OS, then it is likely that the root of the problem lies in the lack of the necessary components for certain platforms. In this case, you can launch the SDK Manager from Android Studio and manually install the missing components.

Subsequently, every time you launch Android Studio, pop-up notifications will appear about the availability of updates by platform, which is quite convenient and will allow projects to keep up with the latest updates from Google.

If we later need to call the SDK Manager, we can do this from Android Sudio itself through the toolbar.

Android SDK is the most popular emulator for the Android mobile platform. This package is used by many developers to create their applications, and ordinary users use it as an introduction to the platform itself.

However, the user is provided with a number of additional capabilities - for example. To replace the firmware or OS kernel, many users use the ADB program, which is part of the above-described Android SDK. This program allows you to establish a connection between the device and a personal computer and perform a number of manipulations with the system.

Installing and configuring Android SDK and ADB package (Android Debug Bridge)

And so, initially you need to download the latest version of the Android SDK emulator. It is recommended to download the zip archive to avoid installation problems. We transfer the folder from the archive called android-sdk-windows to the root folder of drive C, resulting in the path C:\android-sdk-windows.
After making sure that the PC is connected to the Internet, run the SDK Manadger program, which is located in the android-sdk-windows folder. A window like this will appear.
We need to download and install Android SDK Platform-tools and Android SDK Tools. Of all the points, you need to check these two points and click the Install button. The entire installation process will take place automatically. Now to work with the device you need to install its drivers.
Go to the folder C:\android-sdk-windows\platform-tools\ and see the ADB program installed there. The path to the program will look like this: C:\android-sdk-windows\platform-tools\adb and in order not to enter it every time you need to edit the PATH variable. If Windows 7 is installed on your PC, then right-click on the “Computer” shortcut, select “Properties” and in the window that appears, select “Advanced system settings.” If you have Windows XP installed, right-click on “My Computer” ”, then “Properties”.
In the window selected “Advanced” tab, click “Move environment”. In the list of “System variables” parameters, select “path” and click the edit button. In the variable editor window that appears, you need to add the path in the “variable value” item at the end of the line (after the semicolon); c:\android-sdk-windows\tools;c:\android-sdk-windows\platform-tools;. If there were no semicolons, be sure to add them. Save the changes by clicking OK.
Next we move on to the stage of installing the device driver. Many devices from different manufacturers have a PC to synchronize the gadget with a PC, and if you use one, then you probably already have the driver installed. If you do not have drivers, then you need to install them. To do this, go to the folder of the previously installed SDK and launch SDK Manager. The driver installation process is similar to the installation of Android SDK Platform-tools and Android SDK Tools described above. Select Google Usb Driver package from the list and click Install. The drivers will be downloaded to the C:\1\android-sdk-windows\extras\google\usb_driver folder.
Now go to the main menu of your smartphone or tablet, go to Applications and turn on USB Debugging there. We connect the gadget to a personal computer, which will detect a new connection and offer to install a driver on it. We have already successfully downloaded them above, so we install them from that folder. After installation, a new device will appear in the device manager (“Computer” -> “Properties” -> “Device Manager”) - “ADB Interface”.
Now you just need to launch the ADB program. It is better to manage the application using the command line, to call which you need to go to “Start” and enter cmd in the search field and then press enter. Now, for example, to view connected devices, enter the adb devices command. However, it is best to use an alternative method -
