Thanks for reporting this. I work on the Android SDK at Facebook. We are going to put out a dot release of the 3.14 SDK soon to address this. But in the meantime, if you go to LoginButton.java and change the onDraw method to look like this.
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
if (isInEditMode()) {
return;
}
if (!nuxChecked && nuxMode != ToolTipMode.NEVER_DISPLAY) {
nuxChecked = true;
checkNuxSettings();
}
and then rebuild. That should fix your issue.
