Sample App in PlayStore

MAHAndroidUpdater - Sample app has published on Google PlayStore. You can easly test module functionality with downloading it.

Service structure

To provide update information to your app you need to implement service responding json data about application current state. Structure of the json data is as below.
You can provide http:// and https:// services. Library works both of them.

Json with sample data. Link to working sample

    "name":"MAHUpdater Sample",
    "update_info":"On version 1.0 we added bla bla",
  • is_run_mode - service mode: if it's false modul will not react to service and will not show dialogs
  • name - name of the belonging app
  • uri_current - current package path
  • version_code_current - current version code avilable
  • version_code_min - Minimum version code, which does not work normal and had to force to update
  • update_info - Update information
  • update_date - Update date

If one of the variables would not be on json, then modul will not repond to service and act, Try to implement all data.

You can check you json validity with this

There is interface called IUpdateInfoResolver by the help of it you can fetch your update information form own structed service. For example JSON API, XML, Raw text and so on. For this reason there is special init() method accepting this variable. This feature has added by @andrewpros.

Library structure

Library contains from to Dialog component

  • MAHUpdaterDlg- In this situation dialog show to user to update or install newer version and lets to postpone the action to later time and use application
  • MAHRestricterDlg - In this situation dialog urges user to update or install newer version and dont alow use older version

The porpose of lib to show automatically these dialogs on application start if there are any need for it. - MAHUpdaterDlg opens on following situation.

  • Or uri_current value is different from app's installed package url
  • Or version_code_current value is greater than app's installed version on device

- MAHRestricterDlg opens on all situation MAHUpdaterDlg opens and following situation.

  • version_code_min value is greater than app's installed version on device

But when you develop your apps UI and want to show these dialogs there are test modes also and you can open dialogs by calling methods relatively

Proguard configuration

MAHAndroidUpdater uses Gson and Jsoup libs. There for if you want to create your project with proguard you need to add following configuration to your proguard file.
