store - android app running multiple instances -

When I download my app from the store it's installed on the main screen, and on the app menu (when I I click on the circle with 6 points)

When I click from the main screen, it opens an app, and when I click from another place .. it can also be used as a second app. Opens me I just need to run an app ... how can it be fixed?

My manifest

  & lt; Android: name = "dfsfsdp" Android: allowBackup = "True" Android: Icon = "@ Draubable / IC_Luncher" Android: label = "@ string / app_name" Android: Theme = "@ Style / Aaptim" & gt; & Lt; Activity Android: name = ". Startup activity" Android: Screen Orientation = "Portrait" & gt; & Lt; Intent-Filter & gt; & Lt; Action Android: name = "android.intent.action.MAIN" />  

  & lt; Category android: name = "android.intent.category.LAUNCHER" /> & Lt; / Intent-Filter & gt; & Lt; / Activity & gt;  

I think you are not running multiple instances (if you have multiple examples Running failed from mobile), or do you open two applications in the menu that used to close the running application (recent application menu)?

If you see only one, then you are restarting the same example to see your startup activity or post it here to help you.

If this does not help you, take a look to know about the life cycle of an activity:

Best regards.
