Its simple question and hope to find quick answer.
When I open the application and press “home”, after that click on
the app icon it’s open again (still keep open already one in background).
How to force to reopen the app from background instead of open a new one?
This problem dont occur when I’m using longpress “home” button.
Try modifying the
android:launchModevariable in youractivitytag in androidManifest.xml. Depending on your app,SingleToporSingleTaskcould work like what you want. See the developer documentation for details.
