How to use intents for Android custom URL schema?

Question

Basically I have the same question as described in How to implement my very own URI scheme on Android

I followed the instructions from the answered questions and added to my android manifest:

<activity android:name=".MyUriActivity">
    <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="myapp" android:host="path" />
    </intent-filter>
</activity>

Also, I added a new activity like this:

import android.app.Activity;
import android.os.Bundle;

public class MyUriActivity extends Activity {
    @Override
    public void onCreate(Bundle b){
        System.out.println("URI CLICKED!");
    }
}

My Android app is based on Phonegap, so I simply added a link to my index.html like this:

<a href="myapp://foo">Click me</a>

When I clicked, I see in my console the following error:

03-14 12:23:16.177: E/Cordova(629): Error loading url myapp://foo
03-14 12:23:16.177: E/Cordova(629): android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=myapp://foo }

So it seems like I am missing the activity. What's wrong?

Answer 1

1. You didn't call super.onCreate(b);

2. Url myapp://foo doesn't match your IntentFilter. It should be myapp://path/ or you can change the IntentFilter and remove host part.

   <data android:scheme="myapp"/>
