title: Recompiling APK with Google Fit API Issues
body: <p>I'm attempting to reverse engineer an android app called HeartTrace in order to pull sensor data at a higher frequency. I decompiled, adjusted the parameters, and recompiled the APK. However, the app no longer connects to Google Fit API. Does the API require a new signature from Google before recompiling? If not, what is the issue? Thanks!</p>
