Since ADT 17 you can find in the gen folder a BuildConfig class with a DEBUG constant. I often use this constant in my code, since ADT changes the value automatically when you export the application. However with Proguard this doesn't work anymore. E.g. I have following snippet: if (!BuildConfig.DEBUG) { ACRA.init(this); } Proguard notices, that DEBUG is true, so it removes this snippet completely and shrinks the app. After that ADT changes DEBUG constant, but this is too late. The only solution I know is to create my own DEBUG constant and to change it manually again. But I really like the functionality of ADT. Do you know a better solution? Thanks in advance.
