Adding Support Libraries to Android project

Question

Why am I having such a hard time getting into the swing of Android development? I\'ve been developing in various languages over the years and, for some reason, just can\'t s

Answer 1

You have pinpointed the all important document and the relevant section "adding libraries with resources":

http://developer.android.com/tools/support-library/setup.html

The error suggests that your project is not able to find these resources. Please double check the following :

1. You have checked "is library" on the library project

2. You have exported the jars IN THE LIBRARY PROJECT as described in that section

3. You have added the library project as a reference to your app project

4. You have added the android-support-v4.jar to your libs folder in your app project

If this is all definitely correct, check eclipse for any error messages - is it the library project or the app project that lights up like the proverbial Christmas Tree ?

Answer 2

If some of your resource xml files cannot find their respective AppCompat references, make sure you also add the support libraries to your project properties. You do this by:

1.) right clicking on your project in the project

2.) Select properties. (Bottom of the menu)

3.) click Android on the left hand side menu of the new pop up window

4.) In the libraries section, click the "add button"

5.) Select the respective libraries. (If none show up, check to see if they are already displayed in the "libraries" window of the pop up menu. If there is a red x by the desired library, try and resolve that issue first.)

6.) Once there is a green checkmark next to the desired libraries, make sure the "Is Library" option in the libraries section IS NOT selected.

7.) Click apply.

8.) Close the pop up menu.

If this doesn't work, let me know and I can help you out. I spent three hours on the problem so I know pretty much all the possible things that can go wrong with the set up.

I found that setting the Android target to 2.3.3 for the library project android-support-v7-appcompat solves this issue. You don't need to set your project's target higher, but the library's target lower.
