在图标启动器android中显示抗辩通知

Question

In my android application i want to display the count icon badge. i'm using the code from enter link description here .when i test it i always get this error. unable the execute badge.shortcutbadger is currently not support the home launcher package"com.android.launcher" . when i debug it i find that the application dosn't get correctly the package name.

 Intent intent = new Intent(Intent.ACTION_MAIN);
    intent.addCategory(Intent.CATEGORY_HOME);
    ResolveInfo resolveInfo = getPackageManager().resolveActivity(intent, PackageManager.MATCH_DEFAULT_ONLY);
    String currentHomePackage = resolveInfo.activityInfo.packageName;
   //String currentHomePackage = "me.leolin.shortcutbadger.example.MainActivity";
    TextView textViewHomePackage = (TextView) findViewById(R.id.textViewHomePackage);
    textViewHomePackage.setText("launcher:" + currentHomePackage);

so i put it manually but i always get the same message error with the correct package name.

Answer 1

The library you're using only works with the default Samsung, HTC, LG, Sony and other launchers, but not the official Android launcher ( com.android.launcher ).

That's probably why you're having issues testing your app.

You can set the badge count for the launcher icon using the following code, but this feature is not supported for all the devices it supported on the devices like Samsung, HTC etc...

 public static void setBadge(Context context, int count) {
        String launcherClassName = getLauncherClassName(context);
        if (launcherClassName == null) {
            return;
        }
        Intent intent = new Intent("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);
    }

public static String getLauncherClassName(Context context) {

    PackageManager pm = context.getPackageManager();

    Intent intent = new Intent(Intent.ACTION_MAIN);
    intent.addCategory(Intent.CATEGORY_LAUNCHER);

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