android label標籤佔位符 獲取應用名稱

    android:label="@string/app_name" 採用

PackageManager packageManager = context.getPackageManager();
            PackageInfo packageInfo = packageManager.getPackageInfo(
                    context.getPackageName(), 0);
            int labelRes = packageInfo.applicationInfo.labelRes;
            return context.getResources().getString(labelRes);        

   android:label="${xxx}"，採用loadlabel，兼容上面的，沒有佔位符的

  PackageManager packageManager = context.getPackageManager();
            PackageInfo packageInfo = packageManager.getPackageInfo(
                    context.getPackageName(), 0);
            return packageInfo.applicationInfo.loadLabel(packageManager).toString();
