    applicationId "com.scconline"
    minSdkVersion 14
    targetSdkVersion 14
}

buildTypes {
    release {
        minifyEnabled true
    proguardFiles getDefaultProguardFile('proguard-android.txt'),                  'proguard-rules.pro'

    }
      }
  }

  dependencies {
compile project(':androidHorizontalListView')
compile project(':library')
 // compile 'com.google.code.gson:gson:2.2'
  compile files('libs/eventbus-2.4.0.jar')
compile files('libs/fastjson.jar')
compile files('libs/itextpdf-5.5.4.jar')
compile files('libs/jsoup-1.8.1.jar')
compile files('libs/ksoap2-android-assembly-3.1.1-jar-with-   dependencies.jar')
compile files('libs/mockito-all-1.9.0.jar')

compile files('libs/gson-2.2.4.jar')
compile files('libs/gson-2.2.4-javadoc.jar')
compile files('libs/gson-2.2.4-sources.jar')

 }

My proguard rule file is below:-

-dontshrink
-dontoptimize
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
 -verbose
  -keepattributes *Annotation*

  -keep public class com.scconline.**

  -dontnote com.itextpdf.**
  -dontnote org.mockito.**
  -dontwarn com.itextpdf.**

  -keep class android.support.design.widget.** { *; }
  -keep interface android.support.design.widget.** { *; }
   -dontwarn android.support.design.*
 -dontwarn org.objenesis.**

-keep public class * extends android.view.View {
public <init>(android.content.Context);
public <init>(android.content.Context, android.util.AttributeSet);
public <init>(android.content.Context, android.util.AttributeSet, int);
public void set*(...);
 }

-keepclasseswithmembers class * {
public <init>(android.content.Context, android.util.AttributeSet);
 }

 -keepclasseswithmembers class * {
  public <init>(android.content.Context, android.util.AttributeSet, int);
  }

 -keepclassmembers class * extends android.content.Context {
  public void *(android.view.View);
  public void *(android.view.MenuItem);
  }

  -keepclassmembers class * implements android.os.Parcelable {
  static ** CREATOR;
  }

  -keepclassmembers class **.R$* {
  public static <fields>;
 }

  -keepclassmembers class * {
  @android.webkit.JavascriptInterface <methods>;
  }

Use this :

    apply plugin: 'com.android.library'

android {
compileSdkVersion 17
buildToolsVersion "21.1.2"

defaultConfig {
    minSdkVersion 5
    targetSdkVersion 17
}

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
    }

}
}

dependencies {
compile 'com.android.support:support-v4:18.0.0'
}
