AndIag MVP Library

Library to help developers build full MVP apps.



  • Create your presenters extending AIPresenter or implementing AIInterfacePresenter
    • C -> Your view context (Application or Context for Activities, Activities or Context for Fragmentes)
    • V -> Your view interface should implement AIDelegatedView
  • For Activities
    • Extend AIActivity
    • Use annotation @Presenter(presenter = MyPresenter.class)
    • Presenters can comunicate with view between onResume() and onPause().
  • For Fragments
    • Extend AIFragment
    • Use annotation @Presenter(presenter = MyPresenter.class)
    • Presenters can comunicate with view between onViewCreated(...) and onDestroyView(...).


  • Add this lines your root-folder gradle:

    allprojects {
      repositories {
        maven { url '' }

    And this to your module-folder gradle:

    dependencies {
      compile 'com.github.iagocanalejas:andiag-mvp:core:<VERSION>'
  • We have also implemented a common library that contains extensions:

    dependencies {
      compile 'com.github.iagocanalejas:andiag-mvp:commons:<VERSION>'

    Documentation for commons is available here

Basic example

  • Create your repository
    public class MyRepository extends AIRepository {
  • Create your presenter
    @Repository(repository = MyRepository.class) // Not required annotation
    @Repository(repository = MySingletonRepository.class, initiator = "getInstance") // Use this for singletons
    public class MyPresenter extends AIPresenter<MyActivity, MyInterface> {
        public MyPresenter(){
            super(); // Don't forget to call super constructor or repository will not be injected
            //Required default constructor
        /*CALLS TO VIEW*/
        /*CALLS FROM VIEW*/
  • Use it in your Fragment
    @Presenter(presenter = MyPresenter.class)
    public class FragmentMain extends AIFragment<MyPresenter> implements MyInterface {
        /*Fragment methods*/

You can see a working example in the demo-app

Code Examples


  • Use a different Presenter for each purpose
  • Move all your Activity/Fragment logic to the presenter

Pull Requests

I welcome and encourage all pull requests. Here are some basic rules to follow to ensure timely addition of your request:

  1. Match coding style (braces, spacing, etc.) This is best achieved using CMD+Option+L (on Mac) or Ctrl+Alt+L on Windows to reformat code with Android Studio defaults.
  2. If its a feature, bugfix, or anything please only change code to what you specify.
  3. Please keep PR titles easy to read and descriptive of changes, this will make them easier to merge.
  4. Pull requests must be made against develop branch. Any other branch (unless specified by the maintainers) will get rejected.
  5. Have fun!
