Why am I getting the \"Multiple Dex Files Define\" error in my Android project?

Build Path Error: "Multiple Dex Files Define"

Encountering the error "Unable to execute dex: Multiple dex files define" indicates a build path issue within your Android application project. It suggests that multiple DEX (Dalvik Executable) files are attempting to define the same class. Here's how to resolve this issue:

1. Verify Build Path:

• Ensure that your bin folder is excluded from your build path.
• Right-click on your project in Eclipse and select "Properties."
• Navigate to the "Java Build Path" tab and check if the bin folder is present under "Source." If so, remove it.

2. Re-organize Libraries:

• Verify that the Honeycomb library is located in your libs/ folder and not in your source folder.
• Include the libraries within the libs/ folder individually in your build path.

3. Consider Android-support-v4 Library:

• For improved support, consider updating to the android-support-v4 library instead of the Honeycomb support library. This provides Ice Cream Sandwich support.

Additional Tips:

• Restart Eclipse after modifying build paths to ensure changes are applied.
• Check for any duplicate class definitions in your code.
• If the issue persists, try cleaning your project by selecting "Project" -> "Clean" from the Eclipse menu.
