Maybe this belongs in the beginners group, but I'm trying to make my
application available through an intent. It's a volume controller app,
so I figured it might be handy for another application to be able to
call it to adjust volume without having to write their own.
In my volume controller app, I have this activity as my main screen:
<activity android:name=".MainSettings" 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="intent.action.VOLUME_CONTROL"/>
<category
android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
>From another app, I call with:
Intent intent = new Intent();
intent.setAction("intent.action.VOLUME_CONTROL");
startActivity(intent);
Or I've tried:
Intent intent = new Intent("com.roozen.intent.action.VOLUME_CONTROL");
startActivity(intent);
Neither works. The process trying to call the other app fails. I've
also tried removing the category.DEFAULT category from my intent
filter, with no success.
What am I missing?
