    Customization -
    is the production or alteration of mass production for a specific order of consumers by means of a complete set of additional elements or accessories. In our case, this is an individual configuration of your device.


    The compiler-
    is a program that converts text written in algorithmic language into a program consisting of machine instructions. The compiler creates a complete version of the program in the machine language. The term comes from the English "compilation" - association, compilation. The process of converting a source file into an executable is called compilation.


    A smartphone-
    is a mobile phone with enhanced functionality comparable to a PDA - a pocket personal computer. To denote some devices that combine the capabilities of a mobile phone and PDA, the term "communicator" is used.


    Screenshot -
    screenshot - an image received by the computer and showing exactly what the user sees on the monitor screen.


    A digital compass
    is able to determine how your device is currently oriented. Then this information can be used in the mapping program for orientation on the terrain


    Android Market / Play Market -
    online store applications for devices based on OS Android.


    Launcher -
    the shell of the phone (the appearance and interface of the operating system installed in the phone)


    A2DP
    (Advanced Audio Distribution Profile)-
    is a program that defines how two Bluetooth devices must transmit and receive high-quality audio streams. The A2DP profile allows you to transfer in one direction (from a mobile phone to a headset) a stream of 2-channel stereo sound (for example, music).

    ADB - (Android Debug Bridge - Android debug bridge)-
    a tool that is installed with the Android-SDK and allows you to control the device based on the Android OS. You can find it in the "tool" folder unpacked by the SDK.

    Android Debug Bridge (adb) is a versatile command-line tool that lets you communicate with a device (an emulator or a connected Android device). The adb command facilitates a variety of device actions, such as installing and debugging apps, and it provides access to a Unix shell that you can use to run a variety of commands on a device. It is a client-server program that includes three components:

    • A client, which sends commands. The client runs on your development machine. You can invoke a client from a command-line terminal by issuing an adb command.
    • A daemon (adbd), which runs commands on a device. The daemon runs as a background process on each device.
    • A server, which manages communication between the client and the daemon. The server runs as a background process on your development machine.

    adb is included in the Android SDK Platform-Tools package. You can download this package with the SDK Manager, which installs it at android_sdk/platform-tools/. Or if you want the standalone Android SDK Platform-Tools package


    Fastboot -
    Fastboot is a protocol that can be used to re-flash partitions on your device (update the flash file system in Android devices). It is this small tool that comes with the Android SDK (Software Developer Kit), which is an alternative to the Recovery Mode for doing installations and updates.

    Backup -
    saves all settings and settings for recovery in case of data loss.

    Bluetooth-
    is a wireless technology that facilitates the transfer of information between devices (for example, between a mobile phone and a wireless headset). For stable operation, the distance between Bluetooth-devices should not exceed 10 meters.
