Description:
This issue involves the implementation of a CI/CD (Continuous Integration/Continuous Deployment) pipeline for the Android app. Currently, there is no existing pipeline, and the aim is to establish an automated workflow for building, testing, and deploying the application.

Problem
Currently, the Android app lacks a comprehensive unit testing suite, which can lead to challenges in identifying and resolving potential code issues. This absence of unit tests may result in lower code quality and increased difficulty in maintaining the application.

Proposed Solution
To enhance code quality and maintainability, introduce a suite of unit tests for critical components and functionalities of the Android app. Focus on areas prone to errors or those critical to the app's core functionality. Ensure that the unit tests cover various scenarios, including edge cases, to provide robust test coverage.

Additional Context
Adding unit tests contributes to the reliability of the codebase, making it easier to identify and address issues during development. This enhancement falls under the category of "Optimization" as it aims to optimize the development process by incorporating practices that lead to better code quality, improved debugging, and long-term maintainability.

The current CI/CD pipeline lacks a specific job for generating a signed APK, hindering the streamlined deployment process of Android applications. This enhancement proposes the addition of a dedicated job within the CI/CD workflow to automatically generate a signed APK.

Description:
The bug involves the progress bar persisting on the Android app even when an error occurs. Additionally, the progress bar fails to appear when the "regenerate" button is clicked.

Steps to Reproduce:

1. On the home screen, provide a purpose for the content.
2. Click on the "generate" button.
3. The result fragment opens.
4. If an error occurs during content generation, observe that the progress bar does not disappear.
5. Alternatively, after successful content generation, click the "regenerate" button in the result fragment.
6. Note that the progress bar does not appear as expected.

Expected Behavior:

• The progress bar should disappear when an error occurs.
• Clicking the "regenerate" button should trigger the appearance of the progress bar.

Actual Behavior:

• The progress bar persists even when an error occurs.
• Clicking the "regenerate" button does not show the progress bar.

Device Information:

• Device: All devices
• Android OS Version: Android 10+
