This is 2nd attempt of 41e02e96131c1ec66d013e4615348be013518dc4 The difference is adding clearElementsEithLock to Font class which is necessary to delete Fonts object outside of minikin. This method should be removed once http://b/28119474 is fixed. Here is original commit message of reverted change. This lays the groundwork for making SparseBitSet serializable. FontFamily.addFont is only used when the FontFamily is constructed. Thus, instead of calling FontFamily.addFont multiple time, passes Font list to the constructor. By this change, FontFamily can be immutable now. By making FontFamily immutable, We can create FontFamily with pre-calculated SparseBitSet. Bug: 34042446 Bug: 28119474 Bug: 34378805 Test: minikin_tests has passed Change-Id: Ice433931196f5ae79a1a7ee0c98020f914aeb5f2
