private void loadInstalledApps() {

    PackageManager packageManager = getPackageManager();

    List<PackageInfo> packs = packageManager.getInstalledPackages(0);

    for (int i = 0; i < packs.size(); i++) {
        PackageInfo p = packs.get(i);
        ApplicationInfo applicationInfo = p.applicationInfo;
        String name = packageManager.getApplicationLabel(applicationInfo).toString();
        Log.d("xxx", name);
    }
}

我修改了代码，应用名称存储在变量name

中
