# Mobile Pentesting
The Android APK file depends on 4 main components :-
1. Activities : They dictate the UI and handle the user interaction to the smart phone screen
2. Services : They handle background processing associated with an application
3. Broadcast Receivers : They handle communication between Android OS and applications.
4. Content Providers : They handle data and database management issues.
There are additional components which will be used in the construction of above mentioned entities, their logic, and wiring between them. These components are :-
1. Fragments : Represents a portion of user interface in an Activity
2. Views : UI elements that are drawn on-screen including buttons, lists forms etc
3. Layouts : View hierarchies that control screen format and appearance of the views
4. Intents : Messages wiring components together
5. Resources : External elements, such as strings, constants and drawable pictures
6. Manifest : Configuration file for the application
Every main component has it own functionality, which each one of them have different vulnerabilities.
All main components are configured in the manifest file \*\*AndroidManifest.\*\****xml***

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://zeyad-abulaban.gitbook.io/notes/ctf-notes/mobile-pentesting.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
