无法启动Android库项目

Question

i've been trying to run a project but there's a pop up window that says "Android library projects cannot be launched."

Now, my project needs API 7 and i've already installed it in Android SDK Manager. In Properties -> Android -> Target build, i choose Android 4.1.2. I also added these lines to the Android Manifest: <uses-sdk android:minSdkVersion="7" android:targetSdkVersion="7" android:maxSdkVersion="16"/>

yet, when i run my project, the same pop up message shows. Anyone, please help me. Thanks!

Answer 1

Your project surely is configured as "library" thats why you get the message : "Android library projects cannot be launched."

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.

Answer 2

the naive and somewhat literal interpretation of the message would be that your project IS a library project; and indeed, they cannot be launched, only embedded in some main project.

Did you double check that your project is NOT a library project? There used to be a checkbox in the "create new android project" wizard...
