eclipse + eclim + android support library

Question

I have an android gradle project which I compile from the command line. I am using eclipse + eclim to have autocompletion and source code validation. I was an unable to get code completion to work by importing the project as an gradle project into eclipse. I therefore imported /path/to/gradle/project/app/src/main as an android project into eclipse and after some .classpath tweaking I was able to get autocompletion to work.

Now I wanted to import the following android support libraries:

import android.support.annotation.NonNull;
import android.support.v13.app.FragmentCompat;
import android.support.v4.app.ActivityCompat;

but got The import ... cannot be resolved error for all three lines. I then tried Android Tools -> Add Android Support Library which failed miserably. I then tracked down the libraries in question in the Android-SDK and added them manually to the Java Build Path in Eclipse. For some I needed to extract the JAR files from the AAR files as described in this answer. I added the following libraries:

appcompat-v7-26.0.0-alpha1.jar
support-annotations-26.0.0-alpha1.jar
support-v4-26.0.0-alpha1.jar
support-v13-26.0.0-alpha1.jar

This solved the problem for the the first two imports but I still get the error for import android.support.v4.app.ActivityCompat;. I have code completion up to v4 but app is not found.

How can I resolve this issue? Am I still missing some dependency? Is there a better way to get android code completion with eclim?

Answer 1

So i figured it out myself. There was still a dependency missing. In my case I also needed

 support-compat-26.0.0-alpha1.jar

I wrote this script to extract all the jar class files that are somewhere hidden in the android-sdk/folder. It recursivly looks at all subdirectories of the specified Android SDK folder until it either finds a JAR file which is not Javadoc or Source and copies it to a destination directory. If an AAR file is found the content is extracted to a folder of the same name as described in the link of the question and the JAR file in that folder copied with an appropriate name to the given destination directory.
