Android Google API Java Client com.google.api.client.auth.oauth2.draft10

Question

I was trying to do a simple app using the Google Tasks API. Something simple it's turning into a nightmare. Maybe it's something simple, probably it is, but I can't figure it out.

The problem: I was following the example of TasksSample.java from Google but I can't compile even after importing the libraries and dependencies required. I'm using Google API Java Client version 1.5.0.

The problem it's when I access the GoogleAccessProtectedResource class. The import is:

import com.google.api.client.googleapis.auth.oauth2.draft10.GoogleAccessProtectedResource;

I always, and I mean always, no matter what code I have get the following error:

09-26 03:14:38.372: ERROR/dalvikvm(18731): Could not find class 'com.google.api.client.googleapis.auth.oauth2.draft10.GoogleAccessProtectedResource', referenced from method com.greven.test.google.tasks.GoogleTasksTake100Activity.

I really can't see where the problem is. I imported all the needed .jars... I guess

As you can see in this picture the class is obviously imported:

So what other options do I have to fix this? Use Maven? I'm clueless now. I never thought I would have a problem like this. Oh I also tested on different computers, other Google java api client (version 1.4) and same thing happened. Thanks in advance.

It seems as per your screenshot that your imported jar is imported in Eclipse, however for your Android application to work you need these jars to be dropped into a specific folder so that it is added to your APK and so the emulator and the Android devices find it.

It seems you should drop these jars in a folder named /libs at the root of your project. See this SO question: How can I use external JARs in an Android project?

The Article you are referring too uses the /assets folder but this might have changed a few Android versions ago.
