- Where Developers Learn, Share, & Build Careers


I'm developing an Android app for the first time and I wanted to create a session for login and logout. I noticed that most people have suggested using shared references but how can I check whether the user is logged out or not? If the user is not on my app and clicks, the sign in page will not appear! Users can go to the main page immediately.

When user login successfully sets the setLogin function and sets it as correct as boolean and When the user comes back, check if the user isLogin () if this is true, then redirect the user to the main page with intent. 

  Public Boolean isLogin () {return pref.getBoolean ("Login", Incorrect); } Public Zero Satgulin (Boolean X) {SharedPreferences.Editor Editor = pref.edit (); Editor. Input boolean ("login", x); Editor.commit (); }

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error. I am using Python 2.7.8 and the version of SQLAlchemy module is 0.9.8. By the way, using a project flask- SQLAlchemy, it works well, I'm confused.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
