List of default apps showing wrong in Android L

Questions:

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

How to&Answers:

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;
    }

Answer:

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.

Answer:

I’m using this method to check the default launcher.

public void foo(){
       String defaultHomeApp = getDefaultAppByCategory(context, Intent.CATEGORY_HOME);
       ...
}

private String getDefaultAppByCategory(Context context, String category) {
        Intent intent = new Intent(Intent.ACTION_MAIN);
        intent.addCategory(category);
        ResolveInfo resolveInfo = context.getPackageManager().resolveActivity(intent, PackageManager.MATCH_DEFAULT_ONLY);
        return resolveInfo.activityInfo.packageName;
    }

You can use an Intent to obtain which app the user is using as default.

String packageApp= context.getPackageName();
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(<ADD_HERE_THE_CATEGORY>);
ResolveInfo resolveInfo = context.getPackageManager().resolveActivity(intent, PackageManager.MATCH_DEFAULT_ONLY);

The resolveInfo variable will have the default package for that category.
