android-studio-2.1

I'm fairly new to Android, Android Studio, Butterknife and the Gradle build system. However, I'm not new to Java, or programming in general. I'm trying to build an Android app with JDK 1.8 and Butterknife version 8.1.0 , but the Gradle build keeps failing, saying: Error:Could not find property 'options' on task ':app:compileDebugJavaWithJack'.

I've already researched a bit on this, and went through the following pages/articles, but couldn't get a definitive

While working today, it seemed as if suddenly I could no longer debug our application. The funny thing is, if I ran the app normally it would work just fine.

Main.java public class Main extends TabActivity implements OnTabChangeListener { public static TextView txtViewHeading; public static Button btnBack; public static ImageButton btnShare; public static Main mainActivity; public static Boolean isVisible = false; private

I've coded an application which can post tweets and you can see user timelines and search timelines with it. I did that with the TwitterAPI and fabric.io. And if I want to generate an APK file or sync the Gradle file, I get these errors: C:\Users\Alexander\AndroidStudioProjects\FacebookPlus\app\build\intermediates\res\merged\debug\values\values.xml Error:(140) Attribute "srcCompat" has already been defined Error:Execution failed for task ':app:processDebugResources'. com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Users\Alexander

This question already has answers here : How to make API javadocs for Google Play Services APIs and Firebase APIs show up in Android Studio rather than decompiled classes with no docs? (2 answers) I'm trying to view Firebase's Javadoc API for Android on Android studio. I found the javadoc on the internet. For example: DatabaseReference . The problem is that I don't see an option to do it in Android Studio. See screenshot. I have an option to attach the source code of firebase, but can't find it on the web. How do I view Firebase's javadoc in Android Studio? Thanks. The Firebase source is not
