Adding Notification Badge On App Icon In Android

you may think that this is a duplicate question but i want answers to be more specific than any questions that are similar to this. first it says that like facebook having notifica

Solution 1:

I use this class for Samsung and Sony devices (also available https://gist.github.com/Tadas44/cdae2f5995f21bf1c27f). Don't forget to add <uses-permission android:name="com.sonyericsson.home.permission.BROADCAST_BADGE" /> to AndroidManifest.xml

publicclassBadgeUtils {


    publicstaticvoidsetBadge(Context context, int count) {
        setBadgeSamsung(context, count);
        setBadgeSony(context, count);
    }

    publicstaticvoidclearBadge(Context context) {
        setBadgeSamsung(context, 0);
        clearBadgeSony(context);
    }


    privatestaticvoidsetBadgeSamsung(Context context, int count) {
        StringlauncherClassName= getLauncherClassName(context);
        if (launcherClassName == null) {
            return;
        }
        Intentintent=newIntent("android.intent.action.BADGE_COUNT_UPDATE");
        intent.putExtra("badge_count", count);
        intent.putExtra("badge_count_package_name", context.getPackageName());
        intent.putExtra("badge_count_class_name", launcherClassName);
        context.sendBroadcast(intent);
    }

    privatestaticvoidsetBadgeSony(Context context, int count) {
        StringlauncherClassName= getLauncherClassName(context);
        if (launcherClassName == null) {
            return;
        }

        Intentintent=newIntent();
        intent.setAction("com.sonyericsson.home.action.UPDATE_BADGE");
        intent.putExtra("com.sonyericsson.home.intent.extra.badge.ACTIVITY_NAME", launcherClassName);
        intent.putExtra("com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE", true);
        intent.putExtra("com.sonyericsson.home.intent.extra.badge.MESSAGE", String.valueOf(count));
        intent.putExtra("com.sonyericsson.home.intent.extra.badge.PACKAGE_NAME", context.getPackageName());

        context.sendBroadcast(intent);
    }


    privatestaticvoidclearBadgeSony(Context context) {
        StringlauncherClassName= getLauncherClassName(context);
        if (launcherClassName == null) {
            return;
        }

        Intentintent=newIntent();
        intent.setAction("com.sonyericsson.home.action.UPDATE_BADGE");
        intent.putExtra("com.sonyericsson.home.intent.extra.badge.ACTIVITY_NAME", launcherClassName);
        intent.putExtra("com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE", false);
        intent.putExtra("com.sonyericsson.home.intent.extra.badge.MESSAGE", String.valueOf(0));
        intent.putExtra("com.sonyericsson.home.intent.extra.badge.PACKAGE_NAME", context.getPackageName());

        context.sendBroadcast(intent);
    }

    privatestatic String getLauncherClassName(Context context) {

        PackageManagerpm= context.getPackageManager();

        Intentintent=newIntent(Intent.ACTION_MAIN);
        intent.addCategory(Intent.CATEGORY_LAUNCHER);

        List<ResolveInfo> resolveInfos = pm.queryIntentActivities(intent, 0);
        for (ResolveInfo resolveInfo : resolveInfos) {
            StringpkgName= resolveInfo.activityInfo.applicationInfo.packageName;
            if (pkgName.equalsIgnoreCase(context.getPackageName())) {
                StringclassName= resolveInfo.activityInfo.name;
                return className;
            }
        }
        returnnull;
    }
}

Solution 2:

In addition to Daniel Ochoa's solution for Samsung (see comment on OP), I have figured out how this is done for Sony devices.

I've blogged about it here. I've also posted a seperate SO question about this here.

---

Sony devices use a class named BadgeReciever.

1. Declare the com.sonyericsson.home.permission.BROADCAST_BADGE permission in your manifest file:

2. Broadcast an Intent to the BadgeReceiver:

   Intentintent=newIntent();
   
   intent.setAction("com.sonyericsson.home.action.UPDATE_BADGE");
   intent.putExtra("com.sonyericsson.home.intent.extra.badge.ACTIVITY_NAME", "com.yourdomain.yourapp.MainActivity");
   intent.putExtra("com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE", true);
   intent.putExtra("com.sonyericsson.home.intent.extra.badge.MESSAGE", "99");
   intent.putExtra("com.sonyericsson.home.intent.extra.badge.PACKAGE_NAME", "com.yourdomain.yourapp");
   
   sendBroadcast(intent);
   

3. Done. Once this Intent is broadcast the launcher should show a badge on your application icon.

4. To remove the badge again, simply send a new broadcast, this time with SHOW_MESSAGE set to false:

   intent.putExtra("com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE", false);
   

I've excluded details on how I found this to keep the answer short, but it's all available in the blog. Might be an interesting read for someone.
