Add YouTube Data API to Android Studio

So, I am currently messing around with android programming in my free time, and I am using android studio as my ide of choice. I am currently trying to make a very simple app using the youtube api. My issue is that I cant figure out how to actually get the api into my application. I have used file>project structure to add the stuff to my application, but that doesnt work by itself. It stops yelling at me about syntax errors but when it compiles it errors. I researched this a bit and have found that I need to add stuff to build.gradle or settings.gradle(or both) but i havent found a definitive answer on exactly what to do. Everything I have tried thus far hasnt worked. SO if someone could either explain to me what i have to do, or link me to a place where it explains what to do that would be great --edit-- I am so confused right now. I started a new project. I added the libs and it was still able to compile. I then added the imports and it threw errors about it. I then added these to the build.gradle and it was able to compile perfectly ``` compile fileTree(dir: 'libs/youtube', include: '*.jar') compile fileTree(dir: 'libs/youtube/libs', include: '*.jar') ``` But when i added this code that requires the library ``` /** Global instance of the HTTP transport. */ private static final HttpTransport HTTP_TRANSPORT = new NetHttpTransport(); /** Global instance of the JSON factory. */ private static final JsonFactory JSON_FACTORY = new JacksonFactory(); /** Global instance of Youtube object to make all API requests. */ private static YouTube youtube; ``` the syntax was fine but it threw an error upon compiling it ``` Gradle: Execution failed for task ':Apitest:dexDebug'. > Failed to run command: ``` and that was followed by about 100 lines of of file locations Any ideas as to what i am doing wrong?
