If your SDK is an Android-Library, declare

apply plugin: 'com.android.library'

instead of 

apply plugin: 'com.android.application'

in the corresponding build.gradle. You will get an .aar-File (Android ARchive) that would need to be refereced from others in order to use your SDK.

If your SDK is a plain-old-java-Library (no Android resources) you also can use Maven to package it as jar.

  • aar can also be used with Maven. And there is a [project on GitHub](https://github.com/adwiv/android-fat-aar) that makes it easier to wrap few libraries together into one aar. – Alex Cohn Jul 15 '16 at 11:23
  • @sschrass I had created a .aar file, when I tried to import the library in other Project its not building and throwing this error in Message Gradle Attribute application@icon value=(@drawable/ic_launcher) from AndroidManifest.xml:8:9 Attribute application@theme value=(@style/AppTheme) from AndroidManifest.xml:10:9 is also present at Amazon:zupvendor:unspecified:37:9 value=(@style/AppTheme.NoActionBar) – Spiker Jul 15 '16 at 15:46
  • http://stackoverflow.com/a/27360988/1087479 try this. Both manifests (app and lib) define the same thing. – sschrass Jul 15 '16 at 15:51
