ofxPd in android: can't modify patch

I have built an android application that uses ofxPd to interface with pd. The code can be found here.

At the moment, I am loading a pd file called "noisepanning.pd", I load it in the ofApp.cpp source code file. The problem arises when I try to modify it, because the app behaviour does not change, it is like I have not done anything. Moreover, when I try to load another pd patch, the android app does not sound at all.

I am not building again with Xcode when I perform these changes, since I am only interested in the android application. I only use the commands:

make AndroidDebug
./gradlew assembleDebug

Is there something more I should do when I change the pd patch?
