Read the data needed in the Sharedpreferences
Use Sharedpreferences to record the number of programs used
Interface, mode_private specifies that the sharedpreferences data can only be read and written by this application
Sharedpreferences preferences = Getsharedpreferences (
Spname, mode_private);
Editor = Preferences.edit ();
Gets the corresponding value, if there is no value, the description is not written, with true as the default value
Isfirstin = Preferences.getboolean ("isfirstintrue");
Determine the number of times the program runs, if it is the first time to jump to the boot interface, otherwise jump to the main interface
if (!isfirstin) {
Mhandler.sendemptymessagedelayed (Go_home, delaytime);
Else {
Using Handler's Postdelayed method, execute guideactivity after 3 seconds
Mhandler.sendemptymessagedelayed (Go_guide, delaytime);
Editor.putboolean ("isfirstinfalse");
Editor.commit ();
