It's about files not being found. Does the android folder in your project have a structure like this?

I downloaded the android source, no build processing, so how do I build it?

I create a new Android project, and then Android music source AndroidManifest.xml, src, res file copied to the new project, but there was a mistake
F:\projcet0301\Music3\app\build\intermediates\res\merged\debug\values\values.xml
Error:(601, 34) No resource found that matches the given name (at 'colorAccent' with value '#color/colorAccent').

Using FloatingActionButton and adding library design prevents build

while trying to add a FloatingActionButton to my layout, I have been told by AndroidStudio, that I need to add the library design for that:
"This operation requires the library design.
Would you like to add this library now?"
I clicked "Ok", and now the build completely fails.
So far I have managed to find a line in the file "build.gradle", which I hoped was responsible for the issue:
compile 'com.android.support:design:25.0.0'
I tried to comment it out and rebuild, but the error remains.
The errors given are:
C:\AndroidProjects\ChartExample\app\src\main\res\layout\child_edit.xml

I guess these errors are mainly because the build didn't finish and some resource files haven't been generated, but I'm not sure.
Does someone have an idea how to undo what I have done to my project by hitting this fatal button?
Thanks for any help you can give.

The reason was that all of the UI elements mentioned in the error messages had a cycle reference in the layout xml. The error had nothing to do with the libraries added.

Android studio: why do I get errors when I just run the simplest code

the errors imgetting are :
Error:Execution failed for task ':app:processDebugResources'.
com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Android sdk\build-tools\23.0.2\aapt.exe'' finished with non-zero exit value 1
Error:(2) Error retrieving parent for item: No resource found that matches the given name 'android:Widget.Material.Button.Colored'.
Error:(2) Error retrieving parent for item: No resource found that matches the given name 'android:TextAppearance.Material.Widget.Button.Inverse'.
I'm sorry if these questions might seem stupid :).
every time I run the simplest code like just a text box with something is written in it I get these errors.
Also, when I run the default nexus 5 simulators it just loads up to the part where it says android but nothing after that.
Thanks much appreciated.

Try to change the target sdk to 23 and compile build version to 23.1.0 in your app gradle

Running the android in-app billing example aplication

This will probably sound silly but I have no idea how to make the application work.
tutorial for in-app billing
Just like the tutorial says I downloaded the package, I found the files. The problem is there's no project file and I can't get it to work in eclipse.
Anyone used the example app?

I've used it successfully...what seems to be the problem? Once you download the files, bring the project into Eclipse by select "Newn Android Project", "Create project form existing source" and the "Finish." From there, follow the directions regarding changing the package name, etc...

As far as I can determine, the sample Dungeons in-app billing project that I downloaded via Android SDK Manager, does not even compile (this seems to have been fixed, see my comments later in this message..).
As a check, I ran a find command to search for one of the missing resources:
/cygdrive/k/android-sdk-windows/extras/google/play_billing $ find . -name '*.xml' -exec grep edit_payload_title {} \; -print
android:text="#string/edit_payload_title" />
./res/layout/edit_payload.xml
/cygdrive/k/android-sdk-windows/extras/google/play_billing $
As you can see, the resource #string_edit_payload_title is referenced once, but never defined in any of the xml files..

** UPDATE ** I just downloaded it again and it seems to be resolved. At least, it builds and deploys now.. And the string definitions seem to be in place now..
