启动活动从网址 [英] Launch Activity From URL

问题描述

我想有我的应用程序启动时，用户浏览到某个网址。我已经找到了几个例子，他们都在体现同样的事情，但它不是为我工作。我已经把意图过滤器下活动，以及一个接收器。

I am trying to have my application launch when the user browses to a certain url. I have found a few examples and they all have the same things in the manifests but it's not working for me. I have put the intent-filter under an Activity as well as a Receiver.

下面是我的清单片段：

<intent-filter>
  <action android:name="android.intent.action.VIEW"></action>
  <category android:name="android.intent.category.DEFAULT"></category>
  <category android:name="android.intent.category.BROWSABLE"></category>
  <data android:host="www.urbandictionary.com" android:scheme="http"></data>
</intent-filter>

在活动下，我尝试使用onNewIntent，当它是在一个接收机，我尝试使用onReceiveIntent，都与一个简单的Log.i电话，看它是否解雇与否。我运气不好。

When under the Activity, I tried using onNewIntent and when it was under a Receiver, I tried using onReceiveIntent, both with a simple Log.i call to see if it fired or not. I am not having much luck.

推荐答案

我用这个在我的manifest.xml文件：

I use this in my manifest.xml file:

<activity android:name=".SomeName">
    <intent-filter>
        <category android:name="android.intent.category.ALTERNATIVE" />
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <data android:host="google.com" android:scheme="http" />  
    </intent-filter>
</activity>

这将启动活动SomeName。我不使用WWW在Android：主机部分可能会有所作为

This will start activity SomeName. I don't use www in the android:host part maybe that will make a difference.

在活动开始就可以得到这就是.COM后面使用（例如）数据：

When the activity starts you can get the data that's behind the .com using (for example):

Uri data = getIntent().getData();
if(data != null && data.getPathSegments().size() >= 2){
    List<String> params = data.getPathSegments();
    String somestuff = params.get(0);
}

编辑：如果你wan't要能够从活动中检查主机，使用此方法：

If you wan't to be able to check the host from within the activity, use this method:

data.getHost();
