Launch Activity from Preference Activity causes Permission Denial Exception

I'm having a bit of a problem here. What I want to do is launch an Activity from within the PreferenceActivity. So my preference.xml which holds the preference layout looks like this:

<Preference android:title="Launch Activity" >
   <intent android:action="org.momo.SOME_ACTIVITY" />

The manifest is aware of the activity I want to launch..

<activity android:label="@string/app_name" android:name="SomeActivity">
            <category android:name="android.intent.category.DEFAULT" />

            <action android:name="org.momo.SOME_ACTIVITY" />

guess what, I'm getting a Security Exception ( Permission Denial ) when I want to launch it. Am I missing something? My understanding of intents is still a bit incomplete, yet I figured that it must work that way.

Thank you for any help!

Answer 1

Making an intent-filter seems like a slightly roundabout way of doing this. This is a simpler approach:

Answer 2

Fully work example In your preference.xml

   android:action="com.activity.SilentModeList"/> <!-- SilentModeList its activity -->

In your manifest.xml

      <activity android:name="com.activity.SilentModeList"
               <action android:name="com.activity.SilentModeList" />
               <category android:name="android.intent.category.DEFAULT" />

Answer 3

I my case all my xml settings were correct.

But the activity I launched (named AppPreferences) due to bad refractoring existed in to places: [package].AppPreferences and[ [package].commmon.Preferences Because of an import common._, it was taking this as the activity and of course it was not declared in the Android manifest. I just had to delete the second activity from my code and voilà!
