I want to get all default apps in Android L. I used bellow code but they give me a wrong solution. Let see my code first
private void getMyAppLauncherDefault() {
    final IntentFilter filter = new IntentFilter(Intent.ACTION_MAIN);
    filter.addCategory(Intent.CATEGORY_HOME);
    List<IntentFilter> filters = new ArrayList<IntentFilter>();
    filters.add(filter);
    List<ComponentName> activities = new ArrayList<ComponentName>();
    final PackageManager packageManager = (PackageManager) getPackageManager();
    packageManager.getPreferredActivities(filters, activities, null);
    for (ComponentName activity : activities) {
        Log.d(TAG,"======packet default:==="+activity.getPackageName());
    }
}
And this is log. The log shows a wrong result between com.google.android.googlequicksearchbox and com.vlingo.midas. They are both Voice apps, but I set up com.google.android.googlequicksearchbox as default. I do not know why the log shows com.vlingo.midas. How can I fix it? Thanks

update: There are default app names

To check if your App is set as "Default" then please try this code:
 public static boolean isMyAppDefault(Context context) {
        final IntentFilter filter = new IntentFilter(Intent.ACTION_MAIN);
        filter.addCategory(Intent.CATEGORY_HOME);
        List<IntentFilter> filters = new ArrayList<IntentFilter>();
        filters.add(filter);
        final String myPackageName = context.getPackageName();
        List<ComponentName> activities = new ArrayList<ComponentName>();
        final PackageManager packageManager = (PackageManager) context.getPackageManager();
        packageManager.getPreferredActivities(filters, activities, null);
        for (ComponentName activity : activities) {
            if (myPackageName.equals(activity.getPackageName())) {
                return true;
            }
        }
        return false;
    }
                        The code you added above is perfectly right. It does perform what it is meant to.
Now you have set com.google.android.googlequicksearchbox voice app as default and that's why it's showing up in the log.
While com.vlingo.midas is showing probably because it's set as default for some other kind of category instead of voice.
