25 Most Used Android Programming Terminologies:

1) AndroidX
- The AndroidX library package is a set of code libraries that provide backward-compatible enhancements of the Android framework. They also features and widgets that are only available through the library APIs. Each AndroidX library is backward-compatible to a specific Android API level.

2) Android Jetpack
- Android Jetpack is a set of components, tools and guidance to make great Android apps. The Android Jetpack components bring together the existing Support Library and Architecture Components and arranges them into four categories: Architecture, UI, Behaviour, Foundation

3) Gradle
- Gradle is a build system (open source) which is used to automate building, testing, deployment etc. “Build.gradle” are scripts where one can automate the tasks. For example, the simple task to copy some files from one directory to another can be performed by Gradle build script before the actual build process happens.

4) Gradle Plugin
- The Android Gradle Plugin is the supported build system for Android applications and includes support for compiling many different types of sources and linking them together into an application that you can run on a physical Android device or an emulator.

5) minifyEnabled(true/false)
- minify is an Android tool that will decrease the size of your application when you go to build it. It's extremely useful as it means smaller apk files! It detects any code or libraries that aren't being used and ignores them from your final apk.

6) shrinkResources(true/false)
- shrinkResources removes unused resource files from /res folder that are not references in the code.
- shrinkResources is taken into account only if minifyEnabled is true

7) compileSdkVersion
- compileSdkVersion is your way to tell Gradle what version of the Android SDK to compile your app with. Using the new Android SDK is a requirement to use any of the new APIs added in that level.

8) minSdkVersion
- If compileSdkVersion sets the newest APIs available to you, minSdkVersion is the lower bound for your app. The minSdkVersion is one of the signals the Google Play Store uses to determine which of a user’s devices an app can be installed on.

9) targetSdkVersion
- targetSdkVersion is the main way Android provides forward compatibility by not applying behavior changes unless the targetSdkVersion is updated. This allows you to use new APIs (as you did update your compileSdkVersion right?) prior to working through the behavior changes.

10) buildToolsVersion
- buildToolsVersion is the version of the compilers (aapt, dx, renderscript compiler, etc...) that you want to use. For each API level (starting with 18), there is a matching .0.0 version.

11) WakeLock
- A service used by apps to prevent your device from entering its low-power sleep state, which would otherwise clear the app from memory.

12) .dex file
- Android programs are compiled into .dex (Dalvik Executable) files, which are in turn zipped into a single .apk file on the device. .dex files can be created by automatically translating compiled applications written in the Java programming language.

13) ADB
- Android Debug Bridge, a command-line debugging application included with the SDK. It provides tools to browse the device, copy tools on the device, and forward ports for debugging. If you are developing in Android Studio, adb is integrated into your development environment.

14) ContentProvider
- A data-abstraction layer that you can use to safely expose your application's data to other applications. A content provider is built on the ContentProvider class, which handles content query strings of a specific format to return data in a specific format.

15) ProGuard
- ProGuard is an open source command-line tool that shrinks, optimizes and obfuscates Java code. It is able to optimize bytecode as well as detect and remove unused instructions.[3] ProGuard is free software and is distributed under the GNU General Public License, version 2

16) Obfuscation
- ProGuard obfuscates Java and Android programs by renaming classes, fields, and methods using meaningless names, making it harder to reverse-engineer the final application.

17) JetPack Compose
- Jetpack Compose is Android’s modern toolkit for building native UI. It simplifies and accelerates UI development on Android. Quickly bring your app to life with less code, powerful tools, and intuitive Kotlin APIs.

18) Android KTX
- https://blog.mindorks.com/android-ktx-android-development-with-kotlin

19) KTOR
- Ktor is a framework to easily build connected applications – web applications, HTTP services, mobile and browser applications. Modern connected applications need to be asynchronous to provide the best experience to users, and Kotlin coroutines provide awesome facilities to do it in an easy and straightforward way.

20) Kotlin
- It is an open-source, statically typed programming language supported and developed by JetBrains and open-source contributors.

21) android.enableJetifier(true/false)
- Automically converts third-party libraries to use AndroidX

22) android.useAndroidX(true/false)
- AndroidX package structure to make it clearer which packages are bundled with the Android operating system, and which are packaged with your app"s APK.

23) AndroidManifest.xml File
- The AndroidManifest.xml file contains information of your package, including components of the application such as activities, services, broadcast receivers, content providers etc.

* It performs some other tasks also:
- It is responsible to protect the application to access any protected parts by providing the permissions.
- It also declares the android api that the application is going to use.
- It lists the instrumentation classes. The instrumentation classes provides profiling and other informations. These informations are removed just before the application is published etc.
- This is the required xml file for all the android application and located inside the root directory.

24) Activity
- Activity is the part where the user will interacts with your application. In other words, it is responsible for creating a window to hold your UI components.

25) Fragment
- Fragment represents a behavior or a portion of user interface in an Activity. You can combine multiple fragments in a single activity to build a multi-pane UI and reuse a fragment in multiple activities. You can think of a fragment as a modular section of an activity, which has its own lifecycle, receives its own input events, and to which you can add or remove while the activity is running (sort of like a "sub activity" that you can reuse in different activities). And it must always be embedded in an activity. The fragment's lifecycle is directly affected by the host activity's lifecycle - in other words, a fragment cannot be instantiated alone!
