How to Reference a Standard Java Project in an Android Project Using Eclipse After SDK Tools Update 17

How can I reference a standard Java project in my Android project using Eclipse after the SDK Tools Update 17?

// Example of a simple Java class in the standard Java project
public class Utils {
    public static String greet(String name) {
        return "Hello, " + name;
    }
}

After SDK Tools Update 17 in Eclipse, referencing a standard Java project in an Android project involves several steps to ensure proper linkage and functionality. The update might have altered project settings, and this guide will walk you through connecting these projects effectively.

// Example of setting up the reference in Eclipse
// No actual code, but refer to project properties as described above.

Causes

• Update in Eclipse SDK tools may have reset project configurations.
• Changes in the Android development environment affecting project references.

Solutions

• Ensure that both projects (Android and Java) are in the same workspace.
• Right-click the Android project, navigate to 'Properties', and select 'Java Build Path'.
• In the 'Libraries' tab, click 'Add External JARs...' or 'Add Library...' to link your Java project.
• Use the 'Projects' tab to establish a project reference. Make sure your Java project is checked.

Mistake: Not including the Java project in the same workspace as the Android project.

Solution: Ensure both projects are within the same Eclipse workspace.

Mistake: Forgetting to refresh the project after making changes in the build path.

Solution: After adding libraries or project references, right-click on the project and select 'Refresh'.

Mistake: Using the wrong Java version for the Java project compared to the Android project.

Solution: Check and align the Java versions in both projects to avoid compatibility issues.
