We all know how easily and safely to create a new Activity. Now I want to know how to remove an Activity from my project safely.

I've created some activity in my project and feel that they are now needless and I want to delete them. But if I delete manually these files:

  1. The activity's XML file in the /layout folder

  2. The activity's Java file in the /src folder

  3. The <activity></activity> portion from the manifest file

Then,

  • Will no other data related that activity stays in my project? What are those?
  • Is there any simple removal procedure like creating an activity in Eclipse?

I found my answer. To remove an activity, let the name of the activity is activity:

  1. Remove the activity.java file from src folder (java/your.package.name folder for AndroidStudio)
  2. Remove the activity.xml file from layouts folder (layout folder for AndroidStudio)
  3. Remove the activity.xml file from res/menu folder (this is an optional folder)
  4. Remove the <activity></activity> block of the activity from the manifest file
  5. If the <activity> block in the manifest file has a reference (usually in android:label tag) remove the referenced value (usually from values/strings.xml).

According to answers from @ojonugwa ochalifu and @Md Tarik Mahmud you should also right click on app folder then Refractor -> Remove Unused Resources
