App Update Checker

A simple non-Market way to keep your app updated.

All it requires to set up is a URL pointing to a JSON document describing your app's changes.

It will compare its version code (from the manifest file) to the versions listed in the JSON. If there are newer version(s), it will provide the changelog between the installed version and the latest version. The updater checks against the versionCode, but displays the versionName.

While you can create your own OnAppUpdateListener to listen for new updates, OnUpdateDialog is a handy implementation that displays a Dialog with a bulleted list and a button to do the upgrade.

The JSON format looks like this:

{
    "package": {
        "downloadUrl": "http://coolapp.example.com/myapp.apk"
    },

    "0.2": {
    "versionCode": 2,
    "changelog": ["New automatic update checker", "Improved template interactions"]
    },
    "0.1": {
    "versionCode": 1,
    "changelog": ["fixed crash"]
    }
}
