I am trying to get my app on the Google Play store. It is well over the 50MB limit at around 250MB. I have followed the tutorial found here: http://labs.exoa.fr/tutorial-unity-4-apk-splitting-google-play-obb/ This worked great when I started fresh with a new project, both in Unity and on Google Play. However, when I try to implement it in my existing project I get an error: This happens after I click the download button in the example. Any way to narrow down what setting I need change to get this working? The only hint I have is that I am using several prime31 plugins along with the Google Play OBB Downloader plugin. They both seem to want to modify the AndroidManifest.xml file, along with styles.xml, strings.xml, and main.xml. I have done my best to merge these manually, however I'm not really sure what some of it is doing. Any help would be appreciated!
