[英]Android Intent launch from browser
This topic has been covered before, but I can't find an answer specific to what I'm asking. 之前已经讨论过这个话题,但我找不到具体针对我所要求的答案。
Where I am: I followed hackmod's first piece of advice here: Make a link in the Android browser start up my app? 我在哪里:我在这里遵循hackmod的第一条建议: 在Android浏览器中建立一个链接启动我的应用程序? and got this to work with a link in the webpage.
并使用网页中的链接。
However, I'm having trouble understanding the second option (intent uri's). 但是,我无法理解第二个选项(意图uri)。 here's what I've got:
这是我得到的:
<activity android:name="com.myapps.tests.Layout2"
android:label="Auth Complete"
>
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="http" android:host="mydomain.com"
android:path="/launch" />
</intent-filter>
</activity>
Now, with that I can go to "mydomain.com/launch" and it launches my activity. 现在,我可以去“mydomain.com/launch”,它启动我的活动。 this all works well, except that I get the chooser.
这一切都运作良好,除了我得到选择器。 what I want is for it to just launch my activity without giving options.
我想要的是它只是在没有提供选项的情况下启动我的活动。
From the explanation in the post I referenced it looks like thats what intent uris are for,but I can't find a straightforward example. 从我引用的帖子中的解释看起来就像是uris的意图,但我找不到一个直截了当的例子。 what should my link in my webpage look like in order to launch this with no chooser?
我的网页中的链接应该是什么样的,以便在没有选择器的情况下启动它?
I've seen a couple of examples that look something like this: 我看过几个看起来像这样的例子:
<a href="intent:#Intent;action=com.myapp.android.MY_ACTION;end">
However, that doesn't seem to work when I try it. 但是,当我尝试它时似乎不起作用。
My test device is a Galaxy Tab 2. 我的测试设备是Galaxy Tab 2。
any help would be appreciated. 任何帮助,将不胜感激。
I was also trying to launch the app in the recomended way. 我也试图以推荐的方式启动应用程序。 The following code worked for me.
以下代码对我有用。
Code inside the <activity>
block of YourActivity
in AndroidManifest.xml : AndroidManifest.xml中
YourActivity
的<activity>
块内的代码:
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<action android:name="your.activity.namespace.CUSTOMACTION" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
</intent-filter>
Code in the activities onCreate() method : 活动onCreate()方法中的代码:
Intent intent = getIntent();
if(intent != null && intent.getAction() == "your.activity.namespace.CUSTOMACTION") {
extraValue = intent.getStringExtra("extraValueName");
Log.e("AwseomeApp", "Extra value Recieved from intent : " + extraValue);
}
For the code in HTML, write an intent for launching the specific Activity, with the action your.activity.namespace.CUSTOMACTION
, and your application package name your.activity.namespace
. 对于HTML中的代码,编写启动特定Activity的意图,使用操作
your.activity.namespace.CUSTOMACTION
,并将应用程序包命名为your.activity.namespace
。 Your can also put some extra in the intent. 你也可以在意图中增加一些额外的东西。 For example
intent.putExtra("extraValueName", "WOW")
. 例如,
intent.putExtra("extraValueName", "WOW")
。 Then get the required URL by printing the value of intent.toUri(Intent.URI_INTENT_SCHEME)
in the Log. 然后通过在Log中打印
intent.toUri(Intent.URI_INTENT_SCHEME)
的值来获取所需的URL。 It should look like : 它应该看起来像:
intent:#Intent;action=your.example.namespace.CUSTOMACTION;package=your.example.namespace;component=your.example.namespace/.activity.YourActivity;S.extraValueName=WOW;end
So your HTML code should look like : 所以你的HTML代码应如下所示:
<a href="intent:#Intent;action=your.example.namespace.CUSTOMACTION;package=your.example.namespace;component=your.example.namespace/.activity.YourActivity;S.extraValueName=WOW;end">
Launch App
</a>
This is as per what @hackbod suggested in here and this page from developers.google.com. 这是@hackbod在此处以及来自developers.google.com的此页面中提供的内容。
Depending on your intent filter this link should work: 根据您的意图过滤器,此链接应该有效:
<a href="http://mydomain.com/launch">start my app</a>
But you should note that the android system will ask the user if your app or any other browser should be started. 但是你应该注意到android系统会询问用户你的应用程序或任何其他浏览器是否应该启动。
If you want to avoid this implement a custom protcol handler. 如果你想避免这个实现一个自定义的protcol处理程序。 So just your app will listen for that and the user won't get the intent chooser.
因此,只有您的应用程序会监听,用户将无法获得意向选择器。
Try to add this data intent: 尝试添加此数据意图:
<data android:scheme="mycoolapp" android:host="launch" />
With the code above this link should work: 使用上面的代码,此链接应该工作:
<a href="mycoolapp://launch">start my app</a>
I needed a small change to abhishek89m'a answer to make this work. 我需要对abhishek89m的一个小改动做出这个工作的答案。
<a href="intent:#Intent;action=your.example.namespace.CUSTOMACTION;package=your.example.namespace;component=your.example.namespace/.YourActivity;S.extraValueName=WOW;end">
Launch App
</a>
I removed ".activity" after the slash in component name. 我在组件名称中的斜杠后删除了“.activity”。
And I want to add, that custom action is probably the best answer to this problem if you don't want the app chooser to show up. 我想补充一点,如果您不希望应用选择器显示,那么自定义操作可能是解决此问题的最佳方法。
ps I would add this as comment, but I'm a new user and I don't have enough reputation points. ps我会添加这个作为评论,但我是一个新用户,我没有足够的声誉点。
<a href="your.app.scheme://other/parameters/here">
This link on your browser will launch the app with the specific schema like that on your intent 浏览器上的此链接将启动具有特定模式的应用程序,就像您的意图一样
<intent-filter>
<data android:scheme="your.app.scheme" />
<action android:name="android.intent.action.VIEW" />
</intent-filter>
