拿走不谢！
1.APP首次启动判断
2.APP今日启动判断
上菜：
public static boolean isFirstStart(Context context) {
SharedPreferences preferences = context.getSharedPreferences(
"NB_FIRST_START", 0);
Boolean isFirst = preferences.getBoolean("FIRST_START", true);
if (isFirst) {// 第一次
preferences.edit().putBoolean("FIRST_START", false).commit();
return true;
} else {
return false;
}
}
public static boolean isTodayFirstStartApp(Context context) {
try {
SharedPreferences preferences = context.getSharedPreferences("NB_TODAY_FIRST_START_APP", context.MODE_PRIVATE);
String svaeTime = preferences.getString("startAppTime", "2020-01-08");
String todayTime = new SimpleDateFormat("yyyy-MM-dd").format(new Date());
if (!TextUtils.isEmpty(todayTime) && !TextUtils.isEmpty(svaeTime)) {
if(!svaeTime.equals(todayTime)) {
preferences.edit().putString("startAppTime", todayTime).commit();
return true;
}
}
}catch (Exception e){
log(TAG, "是否为今日首次启动APP,获取异常："+e.toString());
return true;
}
return false;
}
