Question

I’m working with an ActivityGroup which is orientation-aware.

When the phone is in portrait-mode Activity A should be started.
When in landscape-mode Activity B should be started.

I do have a custom title in both of these activities, that is called within the corresponding onCreate methods.

I call the initialisation of the custom title like this:

@Override
protected void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    customTitleBar = new CustomTitleBar(getWindow());
    Log.d(TAG, "onCreate called");

    setContentView(R.layout.layout_a);
    customTitleBar.init();
    ...
}

And it all works when I’m launching each Activity on it’s own.

But when trying to start them within the ActivityGroup, my app crashes with this exception:

java.lang.RuntimeException: Unable to resume activity {foo.bar.MyActivityGroup}:
java.lang.RuntimeException: Unable to start activity ComponentInfo{foo.bar.ActivityA}:
android.util.AndroidRuntimeException:
You cannot combine custom titles with other title features

I’m not using any title feature within the ActivityGroup. Is anyone able to help me with this issue?

Answer 1

It seems impossible to create an ActivityGroup with custom titled Activities in it. Creating a Decorator and passing the Activity into this decorator solves the issue.
