Concept and application of intent in Android (ii)--intent filter related options

If multiple activity has the same intent action, what happens when starting with the same action? How do I specify an activity to start?

In cases where multiple activity has the same intent action, if you want to start a specified activity, the <intent-filter>

Add <data android:scheme= "app"/>. Also, write the code that starts as:

StartActivity (New Intent ("Com.w.learnintent.intent.action.myaty", Uri.parse ("app://myaty1"));

second, how to initiate local activity via a browser link?

1. Create a new activity in the new project Launchlocalapp and configure it in the Androidmanifest.xml file:

<activity android:name= ". Localappaty ">
<intent-filter>
<category android:name= "Android.intent.category.BROWSABLE"/> <!--available--
<category android:name= "Android.intent.category.DEFAULT"/>
<action android:name= "Android.intent.action.VIEW"/>
<data android:scheme= "App"/> <!--agreement name--
</intent-filter>
</activity>

install it on the emulator.

2. Write the index.html page (webstorm) and execute:

<a href= "App://localapp" >launch My app</a> <!--Localapp is any parameter--

3. Access the 10.0.2.2:63343/webstormprojects/index.html through the browser in the simulator, click the link to access the activity

(localhost is accessed via the simulator and its address is 10.0.2.2).

Additional

When using Webstorm, pop-up requested without authorization,you can copy URL and open it in browser to trust it issues.

Solution:

File->settings->build,execution,deployment->debugger, select the option on the Allow unsigned requests, and apply it. ）

Third, how can I receive the parameters passed over?

Localappaty.java:

　　　　Uri uri = getintent (). GetData ();
System.out.println (URI);

　　Run the program with console output:

I/system.out:app://localapp
