Application under test has to have permissions specified in its AndroidManifest.xml which enable it to be used with Selendroid. If developer does not add them there, he is not able to test it.

From usability point of view, it is needed that even APK has not some permissions, Droidium will modify application in runtime and dynamically adds them there so developer does not have to touch APK at all.

This also solves the problem with testing APKs when we do not have sources to Android application so we can not add them there manually - exluding all such apps from testing process.
