Android ---- imitate QQ login Remember password and automatic login how to write ?? Urgent

Remember the password and save it to the local database SQLite. When automatic logon is triggered, the system obtains the ID and password data you want to log on to from the local database table every time you start the program, to match the connection server .. There should be two (or one) Flag values at the beginning of the program. One is the flag that triggers the password record, and the other is the sign of automatic login, which is written into the database record, read these two values each time you start the program. If they are true, perform the preceding operations.
