Android Library that checks for updates on Google Play, GitHub, Amazon, F-Droid or your own server. This library notifies your apps' updates by showing a Material dialog, Snackbar or notification. Check out the wiki.

You can download the latest sample APK from Google Play:

Add the repository to your project build.gradle:

repositories {
    maven {
        url "https://jitpack.io"
    }
}

And add the library to your module build.gradle:

dependencies {
    implementation 'com.github.javiersantos:AppUpdater:2.7'
}

By default, the basic usage will show a default dialog when a new version is found on the Play Store (otherwise nothing will be shown). By calling the .start() method, the library will work in background. You can cancel it at any time by calling .stop(). Other customizations are explained below.

AppUpdater appUpdater = new AppUpdater(this);
appUpdater.start();

AppUpdater appUpdater = new AppUpdater(getActivity());
appUpdater.start();

The default usage is configured to display a dialog. However, there are other ways to show the update notice.

new AppUpdater(this)
	.setDisplay(Display.SNACKBAR)
	.setDisplay(Display.DIALOG)
	.setDisplay(Display.NOTIFICATION)
	...

When using Display.DIALOG, you can make the dialog dismissable when touching outside by using .setCancelable(false) (enabled by default).

When using Display.SNACKBAR, you can change the duration by using .setDuration(Duration.NORMAL) (default) or .setDuration(Duration.INDEFINITE).

By default the library will check for updates on the Play Store. However, there are other alternatives, such as GitHub, Amazon, F-Droid or using your own server.

new AppUpdater(this)
	.setUpdateFrom(UpdateFrom.GITHUB)
	.setUpdateFrom(UpdateFrom.GOOGLE_PLAY)
	.setUpdateFrom(UpdateFrom.AMAZON)
	.setUpdateFrom(UpdateFrom.FDROID)
	.setUpdateFrom(UpdateFrom.XML)
	.setUpdateFrom(UpdateFrom.JSON)
	...

When using GitHub you must provide the repo where the library will check for updates: .setGitHubUserAndRepo("javiersantos", "AppUpdater"). Check out the wiki for more details.

When using the XML source you must upload a .xml file somewhere on the Internet following the structure explained in the wiki and add the URL as shown in this example: .setUpdateXML("https://raw.githubusercontent.com/javiersantos/AppUpdater/master/app/update-changelog.xml").

When using the JSON source you must upload a .json file somewhere on the Internet following the structure explained in the wiki and add the URL as shown in this example: .setUpdateJSON("https://raw.githubusercontent.com/javiersantos/AppUpdater/master/app/update-changelog.json").

A detailed description with examples is available at: https://github.com/javiersantos/AppUpdater/wiki

By default, a dialog/Snackbar/notification will be shown whenever a new version is found. However, this can be set to show only every X times that the app ascertains that a new update is available.

new AppUpdater(this)
	.showEvery(5)
	...

You can also show the dialog, Snackbar or notification although there aren't updates by using .showAppUpdated(true) (disabled by default).

new AppUpdater(this)
	.setTitleOnUpdateAvailable("Update available")
	.setContentOnUpdateAvailable("Check out the latest version available of my app!")
	.setTitleOnUpdateNotAvailable("Update not available")
	.setContentOnUpdateNotAvailable("No update available. Check for updates again later!")
	.setButtonUpdate("Update now?")
	.setButtonUpdateClickListener(...)
	.setButtonDismiss("Maybe later")
	.setButtonDismissClickListener(...)
	.setButtonDoNotShowAgain("Huh, not interested")
	.setButtonDoNotShowAgainClickListener(...)
	.setIcon(R.drawable.ic_update) // Notification icon 
	.setCancelable(false) // Dialog could not be dismissable
	...

By default, the "Don't show again" button will be displayed. Use .setButtonDoNotShowAgain(null) to hide the button.

The AppUpdaterUtils class works in the same way that the AppUpdater class does, but it won't display any dialog, Snackbar or notification. When using the AppUpdaterUtils class you must provide a custom callback that will be called when the latest version has been checked.

Adding a callback to the builder allows you to customize what will happen when the latest update has been checked. Keep in mind that when using this method you must be aware of displaying any dialog, snackbar or whatever you want to let the user know that there is a new update available.

AppUpdaterUtils appUpdaterUtils = new AppUpdaterUtils(this)
    //.setUpdateFrom(UpdateFrom.AMAZON)
    //.setUpdateFrom(UpdateFrom.GITHUB)
    //.setGitHubUserAndRepo("javiersantos", "AppUpdater")
    //...
    .withListener(new AppUpdaterUtils.UpdateListener() {
        @Override
        public void onSuccess(Update update, Boolean isUpdateAvailable) {
            Log.d("Latest Version", update.getLatestVersion());
	    Log.d("Latest Version Code", update.getLatestVersionCode());
	    Log.d("Release notes", update.getReleaseNotes());
	    Log.d("URL", update.getUrlToDownload());
	    Log.d("Is update available?", Boolean.toString(isUpdateAvailable));
        }
        
        @Override
        public void onFailed(AppUpdaterError error) {
            Log.d("AppUpdater Error", "Something went wrong");
        }
     });
appUpdaterUtils.start();
