Android Manifest Issue

Turns out that the manifest that gets created when you export to Android assumes that you will be building inside the Android SDK, so it changes the names and package identifiers to match your own.

If, on the other hand, you are using the manifest file generated when you export as part of a plugin, where you have not subclasses the UnityAndroidPlayer class then Android still wants the default package names and name of the activity.

Therefore you have to change the package name and activity name to what is defined in UnityPlayer's own java classes.

Here is my final androidmanifest.xml:

(notice the use of com.unity3d.player and UnityPlayerActivity)

 <?xml version="1.0" encoding="utf-8"?>
 <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.unity3d.player" android:theme="@android:style/Theme.NoTitleBar" android:versionName="1.0" android:versionCode="1" android:installLocation="preferExternal">
