Android - how to add a badge count to an application icon?

Question

how to add badge count on app icon on homescreen , like inbuilt gmail app, facebook app. I can run with Samsung and Sony devices. But others like Motorola , Micromax, HTC , LG does not sets Badge.

So how to set badge count for all android devices?

Answer 1

It is currently not possible to target "all android devices", only for some.

Certain manufacturers (eg Samsung notably) have included this functionality into their customised Android launchers. Also some 3rd-party launchers (eg Nova Launcher) have included an API to accomplish this.

Stock Android does not offer this functionality at the moment on the standard launcher.

You can use library that bring you this ability.

ShortcutBadger is one on them that support many launchers.

For use this library you can add it to your gradle build dependency like this:

dependencies {
    compile 'me.leolin:ShortcutBadger:1.1.4@aar'
}

And add Badge like this:

ShortcutBadger.applyCount(context, badgeCount);
