i'm trying to do mail program. i've done this using jsonArray, Http protocals and some other functions. But, now i want to implement the program likely unread mails and starred mails. If i'm pressing anyof new mail it'll assign likely 1 to database. Otherwise, keep it 0. And, also if i want to set any mails in important (starred) this will keep 1 to database. Otherwise, keep 0. Now, i want to create a database related to these concepts? Anyone know about this concept Please help me to do this? Thanks in advance.i'm trying to do mail program. i've done this u
