搭上Android的广播接收器内的自定义架构链接 [英] Android catch a custom schema link inside a broadcast receiver

问题描述

我目前在做一个自定义方案的意图过滤器，从浏览器中打开自己的应用程序。

是否有可能不是开放活动推出的广播接收机。

我目前的code的活性广播接收机是这样的：

 ＆lt;作用机器人：名字=android.intent.action.VIEW＆GT;
            ＆LT; /作用＆gt;            ＆LT;类机器人：名字=android.intent.category.DEFAULT＆GT;
            ＆LT; /类别＆GT;
            ＆LT;类机器人：名字=android.intent.category.BROWSABLE/＆GT;            ＆lt;数据
                机器人：主机=shortener.com
                机器人：计划=缩略＆GT;
            ＆LT; /数据＆GT;
        ＆所述; /意图滤光器＆gt;
 

下面是我的接收器code。不会触发。尝试了查看动作和自定义操作

 ＆lt;接收机器人：名字=MyReceiver＆GT;
            ＆所述;意图滤光器＆gt;
                ＆lt;作用机器人：名字=com.dg.action.CONFIGURE＆GT;
                ＆LT; /作用＆gt;
                ＆LT;类机器人：名字=android.intent.category.DEFAULT＆GT;
                ＆LT; /类别＆GT;
                ＆lt;数据
                    机器人：主机=shortener.com
                    机器人：计划=缩略＆GT;
                ＆LT; /数据＆GT;
            ＆所述; /意图滤光器＆gt;
        ＆LT; /接收器＆GT;
 

解决方案

我知道这是旧的，但因为有它没有明确和接受的答案，什么哎。作为官方文档所说的那样：

  

...的意图广播机制..是被用来开始Context.startActivity活动意图完全独立的（）。有没有办法为一个BroadcastReceiver看到或与startActivity用于捕获的Intent（）;同样，当您广播一个Intent，你永远不会找到或启动活动。这两个操作在语义上非常不同的：开始用一意图一个活动是修改什么用户当前使用交互的前台操作;广播的意图是，用户通常不知道一个后台操作

希望这是清楚。

I am currently doing a custom scheme intent-filter to open my own app from the browser.

Is it possible to instead opening an activity to launch a broadcast receiver.

My current code for the activity broadcast receiver is like this:

  <action android:name="android.intent.action.VIEW" >
            </action>

            <category android:name="android.intent.category.DEFAULT" >
            </category>
            <category android:name="android.intent.category.BROWSABLE" />

            <data
                android:host="shortener.com"
                android:scheme="shortener" >
            </data>
        </intent-filter>

Here is my receiver code. Doesn't trigger. tried a View action and a custom action

 <receiver android:name="MyReceiver" >
            <intent-filter>
                <action android:name="com.dg.action.CONFIGURE" >
                </action>
                <category android:name="android.intent.category.DEFAULT" >
                </category>
                <data
                    android:host="shortener.com"
                    android:scheme="shortener" >
                </data>
            </intent-filter>
        </receiver>

解决方案

I know this is old, but since there's no clear and accepted answer on it, what the hey. As the official documentation puts it:

...the Intent broadcast mechanism .. is completely separate from Intents that are used to start Activities with Context.startActivity(). There is no way for a BroadcastReceiver to see or capture Intents used with startActivity(); likewise, when you broadcast an Intent, you will never find or start an Activity. These two operations are semantically very different: starting an Activity with an Intent is a foreground operation that modifies what the user is currently interacting with; broadcasting an Intent is a background operation that the user is not normally aware of.

Hope that makes it clear.
