Android Build an Interactive Story App (Retired) Finishing the User Interface Customizing the Buttons

String types not allowed

Under "Customizing the buttons" of Android Development of Ben, when I run the code we make, an error occur to all @drawables of android studio at values.xml. I don't know how but the "R" symbol in my 2 java class under ui package also has an error saying "Cannot Resolve Symbol 'R'".

Here's the error I got that redirects me to values.xml:

C:\Users\Personal\AndroidStudioProjects\InteractiveStory\app\build\intermediates\exploded-aar\com.android.support\appcompat-v7\23.2.1\res\values\values.xml Error:String types not allowed (at 'activity_horizontal_margin' with value ''). Error:Execution failed for task ':app:processDebugResources'.

com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Users\Personal\AppData\Local\Android\sdk\build-tools\23.0.2\aapt.exe'' finished with non-zero exit value 1

Thank You!

It's common for R to not resolve if your project won't compile correctly. That will probably resolve once you get the other issues fixed. Perhaps post your values.xml but it sounds like perhaps you're wrapping the value in "" and in values.xml you don't need to. activity_horizontal_margin should just be a value without quotes I believe.
