Now I am totally confused by this error message: Android library projects cannot be launched.
I carefully checked the build path and library, everything is OK . And there is no error in Problems view. However, when I tried to run my application as an Android project, it failed and showed this message.
What really happened in my code? Any ideas? Thank you in advance!
Regards, Kariya

http://developer.android.com/guide/developing/eclipse-adt.html#libraryProject describes how to set up a project as a library project. Quoted from its content
ReplyDelete================= quoted ===================
Next, set the project's Properties to indicate that it is a library project:
In the Package Explorer, right-click the library project and select Properties.
In the Properties window, select the "Android" properties group at left and locate the Library properties at right.
Select the "is Library" checkbox and click Apply.
Click OK to close the Properties window.
=============== unquoted =============================
So, you open your project properties and "unselect" "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.
