The MainActivity is trying to launch QuickConnectActivity if there was a last connection. The QuickConnectActivity is broken (it has setContentView(R.layout.activity_calibration) instead of setContentView(R.layout.activity_quickconnect) which causes it to miss a view later, but even after fixing that it crashe).
Current workaround: comment out "startActivity(new Intent(this, QuickConnectActivity.class));" from MainActivity.
