The engine uses GameActivity.java found at (Engien\Build\Android\Java\src\com\epicgames\ue4) as the android activity when launching the application (referred to inside AndroidMenifest.xml) and places it inside your projects Intermediates at compile time.
When the project gets built I want to use my own android activity. Is this possible?
Can I use GameActivity.java along with my custom.java activity? How?

Bump this question. I also need this functionality. When I try add my custom activity I get this error:
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.epicgames.TheTaleOfThreeMobile/com.epicgames.ue4.GameActivity}: android.content.ActivityNotFoundException: Unable to find explicit activity class {com.epicgames.TheTaleOfThreeMobile/com.epicgames.ue4.TestActivity}; have you declared this activity in your AndroidManifest.xml?
But I declared this activity in AndroidManifest.xml:
activity android:name="com.epicgames.ue4.TestActivity"
android:label="@string/app_name"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
android:launchMode="singleTask"
android:screenOrientation="landscape"
android:debuggable="true"
android:configChanges="orientation|keyboardHidden">
<meta-data android:name="android.app.lib_name" android:value="UE4"/>
</activity>
I’m not sure if you should add new main activity. Can you try add it like the AdActivity is added?
<activity android:name="com.google.android.gms.ads.AdActivity" android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/>Check your package name. Not sure that you wanted to call the activity com.epicgames.ue4.TestActivity if your app package is com.epicgames.TheTaleOfThreeMobile.
Did you manage to add and launch the activity?
If so, could you send me your XML or tell me how you did it?
I have a java file in which there is an activity.
and I need it to start.
I have already made code that would launch methods from XML, but I still have a problem with launching the activity.
I haven’t been able to do it for a week now.
