Android Web App僅適用於某些設備

Question

我有一個可控制Raspberry上某些功能的webapp，但我在所有android設備上都無法識別它。 該網站服務器是具有Apache的Raspberry Pi 3（均為最新版本）。

出於隱私/安全原因，所有IP地址都用簡單的000.000.000.000進行了更改

我可以通過Chrome中的“添加到家”選項輕松地將webapp添加到我的Samsung S7中，並且運行流暢，但是，在我所有其他家族的Android（和iOS）設備上也沒有，僅將其添加為指向家。

這是manifest.json代碼：

{
  "name": "Casa TAM Domotica",
  "short_name": "CasaControl",
  "theme_color": "#008eff",
  "background_color": "#085491",
  "display": "standalone",
  "orientation": "portrait",
  "start_url": "000.000.000.000",
  "icons": [
    {
      "src": "images/icons/icon-72x72.png",
      "sizes": "72x72",
      "type": "image/png"
    },
    {
      "src": "images/icons/icon-96x96.png",
      "sizes": "96x96",
      "type": "image/png"
    },
    {
      "src": "images/icons/icon-128x128.png",
      "sizes": "128x128",
      "type": "image/png"
    },
    {
      "src": "images/icons/icon-144x144.png",
      "sizes": "144x144",
      "type": "image/png"
    },
    {
      "src": "images/icons/icon-152x152.png",
      "sizes": "152x152",
      "type": "image/png"
    },
    {
      "src": "images/icons/icon-192x192.png",
      "sizes": "192x192",
      "type": "image/png"
    },
    {
      "src": "images/icons/icon-384x384.png",
      "sizes": "384x384",
      "type": "image/png"
    },
    {
      "src": "images/icons/icon-512x512.png",
      "sizes": "512x512",
      "type": "image/png"
    }
  ],
  "splash_pages": null
}

這是index.php代碼：

<?php

$c=$_GET['c'];
$r=$_GET['r'];
$g=$_GET['g'];
$b=$_GET['b'];


/* after every raspberry pi reboot it must execute pigpiod*/
$execute = shell_exec("pigpiod");

if($c == 1)
{
        $execute = shell_exec("pigpiod");
        $execute = shell_exec("pigs w 12 0");
        sleep(1);
        $execute = shell_exec("pigs w 12 1");
    header('Location: 000.000.000.000');
}

if($r != "" AND $g != "" AND $b != "")
{
        $execute = shell_exec("pigpiod");
        $execute = shell_exec("pigs p 22 $r");
        $execute = shell_exec("pigs p 27 $g");
    $execute = shell_exec("pigs p 17 $b");
        header('Location: 000.000.000.000');
}

有什么辦法嗎？

修復它，manifest.json並不總是被系統讀取，我添加了更多的實例

<link rel="manifest" href="manifest.json">
