      Hi,

       

      after an interruption of my app with the home button, I can observe three scenarios after restart:

       

      Scenario 1 (with cli-6.3.0):

      The existing task has been activated.

      The app starts on the page that was previously interrupted.

      The history of the previous session is correct.

       

      Scenario 2 (with cli-6.3.0):

      A new task has been created.

      The app starts with the initialization page.

      The history of the previous session has not been deleted correctly.

      If I press Back, the pages from the previous session are displayed.

       

      Scenario 3 (with older versions, not more)

      The app starts with the initialization page.

      The history of the previous session was deleted correctly.

       

      After installing the app, Scenarios 1 and 2 occur approximately the same number of times.

      After intensive use only scenario 2 occurs.

       

      How can I prevent scenario 2.

       

      I have already experimented with all combinations of Preference KeepRunning true / false and AndroidLaunchMode standard / singleTop / singleTask / singleInstance.

      The result was always the same.

       

      Thanks!

          You might want to use your own backbutton handler instead? Without seeing any code & config.xml settings, it's going to be difficult to troubleshoot.

            I've reduced the app to 2 files.

            Config.xml and index.html.

            And the error still exists.

             

            If I open the app in the course of the installation and then finish it with Back, then inactive task will not be correctly reused.

             

            Each time the app is started, a new task is created.

            The inactive tasks remain unaffected.

             

            When I press Back, the pages of the previously inactive tasks are shown.

             

            index.html:

            <!DOCTYPE html>
