Intent_Filter Action won't work in AndroidManifest

Question

Hi, I have an Activity which also has t olisten to a specific broadcast from a self-made service. I have noticed though that when I add that as an action to my Androidmanifest file the app won't actually start whilst debugging. The Activity is also my MAIN activity :

<intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

But when I add my own extra action to it it simply wont pick up the broadcast and it won't start up out of itself whilst debugging ????

<intent-filter>
   <action android:name="android.intent.action.MAIN" />
   <category android:name="android.intent.category.LAUNCHER" />
   <action android:name="development.android.service.musicServiceUpdate">
</intent-filter>

Any idea whats wrong here or why my activity wont be catching the broadcast ? Is it possible to have two action's specified to a .MAIN action ?

/edit :

Tried the following :

<activity android:name=".nowPlayingGUI"
                  android:label="@string/app_name"
                  android:screenOrientation="portrait"
                    android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
                    android:launchMode="singleTask">    
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <receiver android:name=".nowPlayingGUI">
            <intent-filter>
                <action android:name="development.android.service.musicServiceUpdate"></action>
            </intent-filter>
        </receiver>

That won't work and will throw a :

10-14 11:57:04.412: ERROR/AndroidRuntime(11947): java.lang.RuntimeException: Unable to instantiate receiver development.android.myPlayer.nowPlayingGUI: java.lang.ClassCastException: development.android.myplayer.nowPlayingGUI

10-14 11:57:04.412: ERROR/AndroidRuntime(11947): at android.app.ActivityThread.handleReceiver(ActivityThread.java:2520)

Answer 1

You can only have one action per intent filter (but you can have multiple categories). Add an additional intent filter instead.

Answer 2

Have you added the tag in your androidmanifest.xml

Assuming you have an activity and a broadcast receiver, I think your manifest xml would contain something similar to this inside your app tag:

    <activity android:name=".Main"
              android:label="@string/app_name">
        <intent-filter>
              <action android:name="android.intent.action.MAIN" />
              <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <receiver android:name =".myreceiver">
           <intent-filter>
              <action android:name=development.android.service.musicServiceUpdate />
         </intent-filter>
    </receiver>
