Hi
Felgo and Qt package all libraries that *might* be needed as a dependency at runtime. If you’re sure that some modules are not required at all by your app, you can overwrite the included files with the ANDROID_DEPLOYMENT_DEPENDENCIES variable, as described here: http://doc.qt.io/qt-5/deployment-android.html#android-specific-qmake-variables and save some MBs in file size. There also come quite some examples up when googling for that variable.
In case the APK size is a major issue for you and you can’t manage to accomplish it on your own:
We offer to build a stripped-down version of the Felgo library to remove modules you might not need. This can also save a few MB depending on your use-case. We can create such custom builds with the purchase of a support package or the included support of the Felgo Enterprise plan.
Best,
Günther
