Convert java project into android project on Eclipse [duplicate]

Answer 1

First Way

1. Install ADT plugin
2. Right click on java project
3. Select Android > Convert to Android project.
4. Supply /res folder, /AndroidManifest.xml and /default.properties if needed.

Second Way: UPD

Actually, the "First Way" doesn't work with latest ADT plugin versions, for some reason google has removed the convert command. Another way would be:

1. Check in your java project into a VCS (svn or git or whatever)
2. Delete it from workspace
3. Import the project from VCS
4. On import, select Create New Project -> Android

Third Way

Why not just copy sources to a newly created Android project :) ?

Fourth Way: UDP :)

1. Remove the java project from workspace
2. Start create new Android project wizard
3. Select create from existing source option and point to your java project folder.
