Add Support for External Libraries in Gradle Build File

  1. Create a directory in the Android project for keeping the external library .jar files, e.g. libs
  2. In build.gradle, add
android {
    dependencies {
        compile fileTree(dir: 'libs', include: '*.jar')

This causes Gradle to include all the .jar files in the directory libs in the build.

Add the Apache Commons Library

  1. Download the desired Apache Commons library from
  2. Place the main .jar file of the library in libs
  3. Build as usual (./gradlew assembleDebug)
