对于某些应用程序,getLaunchIntentForPackage为null

我正在构建一项服务,将安装的应用程序列表从Android TV或Fire TV发送到手机.然后,手机会发回它想要启动的应用程序的程序包名称,然后服务就会启动它.

这是创建列表的代码

public List<InstalledApp> GetInstalledApps(boolean isAndroid) {
    PackageManager pm = getPackageManager();
    List<ApplicationInfo> allPackages = pm.getInstalledApplications(PackageManager.GET_META_DATA);
    List<InstalledApp> userPackages = new ArrayList<InstalledApp>();

    for (ApplicationInfo packageInfo : allPackages) {

        if (isSystemPackage(packageInfo)) continue;

        InstalledApp app = new InstalledApp();
        app.setPackageName(packageInfo.packageName);
        app.setAppName(pm.getApplicationLabel(packageInfo).toString());
        if (!isAndroid) {
            app.setIcon(pm.getApplicationIcon(packageInfo));
        }
        app.setAccentColor(getAccentColor(pm.getApplicationIcon(packageInfo)));


        userPackages.add(app);
    }

    return userPackages;
}

这就是我启动应用程序的方式

public void launchApp(String packageName) {
    PackageManager pm = getPackageManager();
    Intent intent = pm.getLaunchIntentForPackage(packageName);
    startActivity(intent);
}

在Fire TV上,一切都很完美,但在Android TV上,许多应用程序的意图始终为空.这些才一点点.
