Cannot Inherit From Final ProgressBarDrawable

Mar 11, 2025 by ADMIN 46 views

Introduction

As a developer, you may have encountered the error "cannot inherit from final ProgressBarDrawable" while building your Android production. This error can be frustrating, especially when you're working on a project with a tight deadline. In this article, we'll delve into the causes of this error and provide a step-by-step guide on how to resolve it.

Understanding the Error

The error "cannot inherit from final ProgressBarDrawable" occurs when you try to extend a class that has been marked as final. In this case, the ProgressBarDrawable class has been marked as final, which means it cannot be inherited from.

Causes of the Error

There are several reasons why you may encounter this error:

Outdated Dependencies: If your dependencies are outdated, they may contain deprecated APIs that are causing the error.
Incorrect Class Hierarchy: If the class hierarchy is incorrect, it may lead to this error.
Missing or Incorrect Imports: Missing or incorrect imports can cause the error.

Resolving the Error

To resolve the error, follow these steps:

Step 1: Update Dependencies

First, update your dependencies to the latest version. You can do this by running the following command in your terminal:

npm install

yarn install

This will update all your dependencies to the latest version.

Step 2: Check Class Hierarchy

Next, check the class hierarchy to ensure that it is correct. In this case, the CircleProgressBarDrawable class is trying to extend the ProgressBarDrawable class, which is marked as final.

Step 3: Create a New Class

Instead of extending the ProgressBarDrawable class, create a new class that contains the necessary functionality. You can then use this new class in your code.

Step 4: Update Code

Update your code to use the new class instead of the CircleProgressBarDrawable class.

Step 5: Test Code

Finally, test your code to ensure that it is working correctly.

Example Use Case

Here's an example use case:

Suppose you have a class called CircleProgressBarDrawable that extends the ProgressBarDrawable class. However, the ProgressBarDrawable class has been marked as final, which means it cannot be inherited from.

// CircleProgressBarDrawable.java
public class CircleProgressBarDrawable extends ProgressBarDrawable {
    // code here
}

To resolve this error, you can create a new class called CustomProgressBarDrawable that contains the necessary functionality.

// CustomProgressBarDrawable.java
public class CustomProgressBarDrawable {
    // code here
}

You can then use this new class in your code.

// MainActivity.java
public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        CustomProgressBarDrawable progressBarDrawable = new CustomProgressBarDrawable();
        // code here
    }
}

Conclusion

In conclusion, the error "cannot inherit from final ProgressBarDrawable" can be resolved by updating dependencies, checking class hierarchy, creating a new class, updating code, and testing code. By following these steps, you can resolve this error and ensure that your Android production builds successfully.
