Custom scheme doesn't seem to launch in the app intent

Question

I\'m trying to create an Android app that needs to use OAuth to authenticate (with the Google Wave data API)

I\'ve specified a custom scheme in my AndroidManifest.

Answer 1

I had the exact same problem (OAuth) and this is how I fixed it.

I've separated my Main from the class that will act on the URI.

Here's how the AndroidManifest.xml should look like:

<?xml version="1.0" encoding="utf-8"?>

[snip]

          <activity android:label="@string/app_name" android:name="MainActivity">
           <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
           </intent-filter>
          </activity>
          <activity android:label="@string/app_name" android:name="OAUTHActivity">
           <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="myscheme" android:host="oauth" />
           </intent-filter>
          </activity>
         </application>

    [/snip]

And I was able to open URIs like myscheme//oauth?oauth_verifier=xxx&oauth_token=yyy

Answer 2

Actually, it's possible to do it with only one activity, just creating one more intent filter. Like this:

<activity android:name=".MyActivity"
      android:label="@string/app_name">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
    <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="my_scheme" android:host="my_app_host.com" />
    </intent-filter>
</activity>

Answer 3

According to the common tasks that should be:

<scheme android:name="braindump" />

Answer 4

I don't think this is exactly the cause of your problem, but I got this same error "You do not have permission to open this page" and it was because I was using a scheme with a capital letter. eg "Celly" instead of "celly". This worked fine in the emulator but failed on real devices. Changing it all to lowercase fixed it.
