I've been recently looking at some sample AndroidManifest.xml files for several Unity projects and periodically, some projects have a main app Activity with the following meta-data tag:><meta-data android:name="unityplayer.UnityActivity" android:value="true" />
Does anyone know what purpose adding that particular meta-data tag does?
Not all sample projects that I've seen have that and the Unity Android plugin documentation makes no reference to it. I haven't been able to find any explanation for it anywhere in my searches online. It just seems to appear. Any ideas? Hoping someone from Unity can chime in :)
**Update (2016/08/25)**: I've done a bit of investigating and it seems to have made it's appearance in the default generated AndroidManifest.xml since Unity 4.3.3f1. By setting the value to "true" it appears to impose a fixed set of attributes/values on the main Activity tag. If the value is "false", or the meta-data tag doesn't exist in the AndroidManifest.xml, then the main Activity tag is left unmodified from the result of merging of the manifest files found within the Assets/Plugins/Android/ folder. This would suggest that it's a toggle for ensuring the necessary attributes are used when a Unity-based Activity (UnityPlayerActivity, UnityPlayerNativeActivity, UnityPlayerProxyActivity) -- not a subclass of one -- is set as the main application Activity. I'm just guessing, of course.
