Android - Activity Home/Up arrow has additional padding/margin with SDK 24
问题 I've just updated my app from using SDK 23 to SDK 24. A problem has arisen for my activities that have show the Up/Home arrow (i.e., getSupportActionBar().setDisplayHomeAsUpEnabled(true) ) in that there is now additional (unwanted) space between the Up arrow and the activity title. For activities that don't have an Up arrow, the activity title is in exactly the same place as before, which suggests the additional padding/margin is associated with the Up arrow rather than with the activity
