如何在 chrome 上的新方案中将参数传递给 android Intent? [英] How do I pass parameters to android Intent in new scheme on chrome?

问题描述

我有一个网络应用程序通过 iframe Intent 在 android 上调用本机应用程序，根据以下内容在 chrome 25 中不起作用......

https://developers.google.com/chrome/mobile/docs/intents>

意图的结构如下......

app://Requesttype=Testing&Type=123&tn=0000000000

在新的 intent://方案中，我将如何将 app://后面列出的参数传递给本机应用程序?我一直没能找到一个例子.

解决方案

使用新方案，您可以将参数作为附加项传递给应用程序，但必须对 URI 进行如下编码:

<a href="intent://whatever/#Intent;scheme=myapp;package=com.what.ever.myapp;S.myextra=mystring;end">做任何事</a>

这将传递一个名为myextra"的额外字符串，其值为mystring".看看 Android Code 我们可以看到额外的参数需要如何编码.myextra"参数开头的S"将其定义为字符串.其他类型可以是:

String =>'S'布尔值 =>'B'字节 =>'乙'字符 =>'C'双 =>'d'浮动 =>'F'整数 =>'一世'长 =>'我'短 =>'s'

例如，如果我们想传递两个额外的参数，一个整数和一个字符串，我们可以这样做:

<a href="intent://whatever/#Intent;scheme=myapp;package=com.what.ever.myapp;S.name=Perico%20de%20los%20Palotes;i.age=35;end">做任何事情

请注意，您需要对所有参数进行 url 编码.

在您的 Android 应用中，您需要接受这些附加功能.在您的活动的onCreate"事件中:

Bundle parametros = getIntent().getExtras();如果(额外的！= null){String name = extras.getString("name");整数年龄 = extras.getInt("age");if (name!=null && age!=null){//做任何你必须做的事//...}}别的{//没有额外的，克服它！}

当然，还要在清单中添加过滤器 android.intent.category.BROWSABLE，如此链接.

I have a web app calling a native app on android via an iframe intent which does not work in chrome 25 according to the following....

https://developers.google.com/chrome/mobile/docs/intents

The intent was structured like the following....

app://Requesttype=Testing&Type=123&tn=0000000000

In the new intent:// scheme how would I go about passing the parameters listed after app:// to the native application? I haven't been able to find an example.

解决方案

With the new scheme, you can pass arguments as extras to the App, but you must encode the URI as follows:

<a href="intent://whatever/#Intent;scheme=myapp;package=com.what.ever.myapp;S.myextra=mystring;end">Do Whatever</a>

This will pass an extra String called "myextra" with the value "mystring". Having a look at the Android Code we can see how the extra parameters need to be coded. The "S" at the beginning of the "myextra" parameter defines it as a String. Other types can be:

String => 'S'
Boolean =>'B'
Byte => 'b'
Character => 'c'
Double => 'd'
Float => 'f'
Integer => 'i'
Long => 'l'
Short => 's'

For example, if we want to pass two extra parameters, an Integer and a String, we can do this:

<a href="intent://whatever/#Intent;scheme=myapp;package=com.what.ever.myapp;S.name=Perico%20de%20los%20Palotes;i.age=35;end">Do Whatever</a>

Note that you'll need to url-encode all the parameters.

In your Android app, you'll need to accept those extras. In the "onCreate" event of your Activity:

Bundle parametros = getIntent().getExtras();
if (extras != null){
    String name = extras.getString("name");
    Integer age = extras.getInt("age");

    if (name!=null && age!=null)
    {
       //do whatever you have to
       //...
    }
}else{
     //no extras, get over it!!
}

And, of course, add the filter android.intent.category.BROWSABLE in your manifest as shown in this link.
