我的清单上有2个错误，我也不知道为什么。

谢谢。

第一个错误是：

Web app manifest does not meet the installability requirementsFailures: Manifest does not have a PNG icon of at least 192p

第二个错误是

Is not configured for a custom splash screenFailures: Manifest does not have a PNG icon of at least 512px.
A themed splash screen ensures a high-quality experience when users launch your app from their homescreens. Learn more.

清单的我的php代码

  

$ manifest = [       “ dir” =>“ ltr”，       “ lang” =>“ {$ code_langue}”，       “ name” =>“ {$ siteName}”，       “ short_name” =>“ {$ shortName}”，       “ description” =>“ {$ description}”，       “ scope” =>“ {$ scope}”，       “ display” =>“独立”，       “ start_url” =>“ {$ scope}”，       “ theme_color” =>“＃317EFB”，       “ orientation” =>“ any”，       “ background_color” =>“ #fff”，       “ related_applications” =>“”，       “ prefer_related_applications” =>“假”，       “屏幕截图” => []，       “ generated” =>“ true”，       “图标” => [         “ src” =>“ {$ image_512}”，         “ sizes” =>“ 192x192 512x512”，         “ type” =>“ image / png”       ]，       “ src” =>“ {$ image_512}”，       “ sizes” =>“ 512x5122”，       “ type” =>“ image / png”];

生成了json
