I tried hard to debug my WebRTC app after migrating to Meteor 1.5. One problem was that the local camera could not be accessed. I finally found out that permission granting does not work anymore in Meteor 1.5 as it was at 1.2 times.
You can only see this if you do a production build and install the app. No permissions will be required, even if they have been defined in AndroidManifest.xml. You have to tap on the app in the settings and grant the permissions manually. After that, the app works just fine.
Has there been a major change in how Meteor handles the manifests now? When my app was still on Meteor 1.2, everything worked fine. Or is this related to changes in the permissions management system of Android itself, that have not been reflected in Cordova somehow?
