I made a directory "libs" at app/libs. The same level as my "build" and "src" directory.

Then i Copied my jar ("Peanuts.jar") into that folder.

Next, i right clicked it and selected 'Add as library'.

This .jar uses 2 other jars, one for json and another for mysql. I've created the JAR in eclipse, EXPORT > JAVA > RUNNALE JAR and checked "Extract required libraries into generated jar.

my app.iml contains:

    <orderEntry type="library" exported="" name="Peanuts" level="project" />

my build.gradle contains:

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:21.0.+'
    compile files('libs/Peanuts.jar')
}

This is because Peanuts and appcompat have some file in common. Try removing appcompat and clean and rebuild the application. It might work fine.
