Which one of these doesn't the Android Software Developer Kit include?
- A.
  
  Recorder
- B.
  
  Tutorials
- C.
  
  A debugger
- D.
  
  Sample code
Correct Answer
A. Recorder

Explanation
The Android Software Developer Kit (SDK) includes various tools and resources for developers to create Android applications. These include tutorials, a debugger, and sample code. However, a recorder is not included in the Android SDK. A recorder is typically used for capturing audio or video, but it is not a core component of the SDK.

  Android
- B.
  
  Linux
- C.

- D.
  
  Windows
Correct Answer
A. Android

Explanation
Android SDK is not available on the Android platform because it is the software development kit specifically designed for developing Android applications. It provides various tools, libraries, and APIs necessary for Android app development. Therefore, it wouldn't make sense for Android SDK to be available on the Android platform itself.

Android apps are packed in the .apk format. The .apk file format stands for Android Package Kit, which is a package file format used by the Android operating system for distribution and installation of mobile apps. The .apk file contains all the necessary components of an Android app, including the code, resources, and manifest file. When users download and install an Android app, they are essentially installing the .apk file onto their device.

Fastboot is a diagnostic protocol used in Android devices that allows for communication between a computer and the device's bootloader. It enables users to flash firmware, unlock the bootloader, and perform various diagnostic tasks on their Android device. It is not a library, debugger, or language, but rather a protocol that facilitates communication and troubleshooting between a computer and an Android device.

A. Extract

Explanation
The correct answer is "extract." In fastboot, the commands "flash," "erase," and "format" are commonly used to perform various operations on Android devices. However, "extract" is not a recognized fastboot command. Fastboot is a protocol used for communication between a computer and an Android device in bootloader mode, allowing users to modify the device's firmware or recover it from a bricked state.
