This answer is for someone coming from search engine due to similar kind of issue.

I had,

Launcher Activity -> A 
Main Activity -> B

In your AndroidManifest, in the activity tag, just add

android:alwaysRetainTaskState="true"

Answer 5

This is because another instance of app is launching when icon is pressed.

  // To prevent launching another instance of app by clicking app icon 
                if (!isTaskRoot()
                        && getIntent().hasCategory(Intent.CATEGORY_LAUNCHER)
                        && getIntent().getAction() != null
                        && getIntent().getAction().equals(Intent.ACTION_MAIN)) {

                    finish();
                    return;
                }

write the above code in your launcher activity before calling setContentView. This will solve the problem
