Question

我正在尝试获取设备中安装的所有应用程序的列表。我为此目的编写了以下代码：

  public static List<ApplicationInfo> getInstalledApplication(Context context) {
        PackageManager packageManager = context.getPackageManager();
        List<ApplicationInfo> apps = packageManager.getInstalledApplications(PackageManager.GET_META_DATA);
        Collections.sort(apps, new ApplicationInfo.DisplayNameComparator(packageManager));
        return apps;
    }

我正在使用Collections.sort对我的应用进行排序。现在，在运行上面的代码时，我遇到的问题是：

无法在包0中输入0x7f050000（t = 4 e = 0）（错误-75）name = com.android.keyguard

我的应用不崩溃，但在发布时需要时间。请帮我解决这个问题。

编辑：片段中的其他方法是：

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_settings, container, false);

        getAllApp();

        lv = (ListView)view.findViewById(R.id.applist);
        lv.setAdapter(new CustomAdapter(getActivity(),appNames,packageNames,appIcons));

        return view;
    }


    private void getAllApp() {
        final PackageManager packageManager = getActivity().getPackageManager();
//        List<ApplicationInfo> installedApplications =
//                packageManager.getInstalledApplications(PackageManager.GET_META_DATA);
        List<ApplicationInfo> installedApplications =
                getInstalledApplication(getActivity());

        for (ApplicationInfo appInfo : installedApplications)
        {
            appNames.add(String.valueOf(appInfo.loadLabel(packageManager)));
            packageNames.add(appInfo.packageName);
            appIcons.add(getActivity().getPackageManager().getApplicationIcon(appInfo));
        }
    }
