"Android library projects cannot be launched"?

Now I am totally confused by this error message: Android library projects cannot be launched.

I carefully checked the build path and library, everything seems "OK", and there is no error on Problems view, however, when I tried to run my application as an Android project, it failed and showed that message.

Any explanation for why it's happening is appreciated!

right-click in your project and select Properties. In the Properties window -> "Android" -> uncheck the option "is Library" and apply -> Click "ok" to close the properties window.

This is the best answer to solve the problem

From Android's Developer Documentation on Managing Projects from Eclipse with ADT:

Setting up a Library Project

Next, set the project's Properties to indicate that it is a library project:

  1. In the Package Explorer, right-click the library project and select Properties.
  2. In the Properties window, select the "Android" properties group at left and locate the Library properties at right.
  3. Select the "is Library" checkbox and click Apply.
  4. Click OK to close the Properties window.

So, open your project properties, un-select the "Is Library" checkbox, and click Apply to make your project a normal Android project (not a library project).

It says “Android library projects cannot be launched” because Android library projects cannot be launched. That simple. You cannot run a library. If you want to test a library, create an Android project that uses the library, and execute it.
