Cant run the tool since i can't build the APK - catch-22 A suggestion from a particular analytics middleware was that there is a bug in Unity which inflates number of methods. It's not that Unity added additional methods but that it "mishandles" other ( plug-in ) methods by duplicating them. The claim, which they made, is that they reduced methods by 5,000 in the latest version of their plugin. Yet, our build, which used to build previously, fails. Their engineer is firmly suggesting a Unity issue. There is a second thread, this one from the rumor-mill, that unity 5.5 is going to handle DEX differently and resolve current issues we are experiencing with the 5.3. I don't have the specifics. What is it that 5.5 is doing that 5.3 isn't doing? I am very reluctant to move to 5.5 at this time since it is just in early beta.
