I would like to write application in Android Studio (v. 1.1.0) to browse reddit. I found API wrapper jReddit and would like to use it.
At first I just try to initialize RestClient (method is called when I click on button), but I get error:

Code with initialization:
public void tlacitko(View v)
{
RestClient restClient;
restClient = new PoliteHttpRestClient();//= new HttpRestClient();
//User user = new User(restClient, "nick", "dasdasd");
}
Libs to compile:
compile 'com.android.support:appcompat-v7:21.0.3'
compile files('libs/jreddit-1.0.2.jar')
compile files('libs/httpclient-4.4.jar')
compile files('libs/jna-4.1.0.jar')
compile files('libs/jna-platform-4.1.0.jar')
compile files('libs/commons-io-2.4.jar')
I think I have all needed libs, where can I do mistake?
UPDATE
I just try again my project. I add dependency:
dependencies {
//compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.2.0'
compile('com.github.jreddit:jreddit:1.0.3') {
exclude group: 'org.apache.httpcomponents', module: 'httpclient'
exclude module: 'junit'
}
compile 'org.apache.httpcomponents:httpclient-android:4.3.5.1'
}
but when I try to run project, I get error:
Error:duplicate files during packaging of APK D:\ZCU\AndroidStudioProjects\JredditTest\app\build\outputs\apk\app-debug-unaligned.apk

You can ignore those files in your build.gradle:
android {
packagingOptions {
exclude 'META-INF/DEPENDENCIES'
}
}
Error:Execution failed for task ':app:packageDebug'.

This error occurs only in Android studio. I tried Maven dependency in Eclipse and jreddit work great there.
I am the current maintainer for the jReddit project.
I recently created a sample android example which makes use of jreddit library. Haven't done much for the example, but the android app would work fine with the jreddit jar in it.
I took me a while to figure things out, but basically these are the dependencies that I've used in order to make the android app work and I think it should help you out as well.
Also, pay attention to the version that I posted (1.0.3) which is the latest jReddit release which includes several changes that help android developers out.
