My app is using the pdftron lib (PDFViewCtrlTools). Here there is the class Utils.java and following methods:
public static void debugLogD(String tag, String msg) {
if (BuildConfig.DEBUG) {
Log.d(tag, msg);
}
}
public static void debugLogV(String tag, String msg) {
if (BuildConfig.DEBUG) {
Log.v(tag, msg);
}
}
I am getting following error when release building the app:

There are more people having problems when in a project library BuildConfig.DEBUG is used, but I could not find any solution yet for this.
The problem appears only when using tools/proguard/proguard-android-optimize.txt instead of tools/proguard/proguard-android.txt
