Android Question Returning from an application launched

[ComposerB4A]

Hi to all, thaks to all aids in forums, any person know ¿how Return from an application launched?
(i know that is possible from a service but ¿Which function to use?)
(the idea is return to "previous screen")

Sub Process_Globals
End Sub

Sub Globals
End Sub

Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("7")
End Sub

Sub Activity_Resume
End Sub

Sub Activity_Pause (UserClosed As Boolean)
End Sub

Sub Button1_Click
Dim In As Intent
File.Copy(File.DirAssets, "1.jpg",File.DirRootExternal,"1.jpg")
In.Initialize(In.ACTION_VIEW, "file://" & File.Combine(File.DirRootExternal,"1.jpg"))
In.SetType("image/*")
StartActivity(In)   
End Sub

Not sure that I understand the question correctly. Calling Activity.Finish will close the current activity and will show the previous activity (or app).

Thanks,
I may that not well explained the question,
Applying the theme for "my app" (code of up) launch the viewer (external), i want return to "my app", not close "my app", i want close the "viewer" (external), most probably using a service.
I actually use the "startactivity(main)" in one service (for return to "my app" screen), but i not know if this is correct.

This is the correct way if you want to resume your activity when it is in the background.
