Question

我想获得Android L中的所有默认应用程序。我使用了以下代码，但它们给了我一个错误的解决方案。让我们先看看我的代码

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());
    }
}

这是日志。该日志显示com.google.android.googlequicksearchbox和com.vlingo.midas之间的错误结果。它们都是语音应用，但我将com.google.android.googlequicksearchbox设置为默认值。我不知道为什么日志会显示com.vlingo.midas。我该如何解决？感谢

更新：有默认的应用名称

Answer 1

检查您的应用是否设置为＆＃34;默认＆＃34;那么请试试这段代码：

 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 2

您在上面添加的代码是完全正确的。它确实表现了它的意图。

现在您已将com.google.android.googlequicksearchbox语音应用设置为默认值，这就是它在日志中显示的原因。虽然显示com.vlingo.midas可能是因为它被设置为其他类别而非语音的默认值。

Answer 3

我正在使用此方法检查默认启动器。

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;
    }

您可以使用Intent来获取用户默认使用的应用程序。

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);

resolveInfo变量将具有该类别的默认软件包。
