App not installed as package appears to be invalid

[matalog]

I have been following the How to create an android application thread, in the tips n tricks section of the forum, and can compile the example app, although when I copy it over to my phone, it always gives the error, "App not installed as package appears to be invalid.". I am trying to install it on a Samsung S20+. I have tried 3 versions of jdk 8u202,8u421 and 32 bit jdk1.8 I had from a while ago.

Is there anything I shoud be looking at to allow the app to install on the phone. This is the app I create https://www.dropbox.com/scl/fi/vb6vzri7 ... sid1s&dl=1

You might have to sign the APK. I did when trying to run my code on my Pixel. Here's a Stack Overflow post on how to do this.

if not signed, you MUST enable debugger !! otherwise it does not isntall

you can enable debugger in app compile
and immediatly close it with CloseDebugOutput() .. this makes a feeling like it has no debugger

Yes, that worked, I prefered to try this over installing 18gb of ADK. Thanks.

The program has a Spiderbasic splash screen when it has loaded, is there a way to have no splash screen, and just get straight into the program?

This is what I compiled:

Code: Select all

Enumeration
  #mf
  #mfFont
  #mfTime
EndEnumeration

Declare Start()
Declare ShowTime()

;No debug
CloseDebugOutput()

Start()

Procedure Start()
  
  LoadFont(#mfFont, "", 50)
  
  OpenWindow(#mf, 0, 0, 0, 0, "", #PB_Window_Background)
  TextGadget(#mfTime, 10, 100, 300, 50, "00:00:00")
  SetGadgetFont(#mfTime, FontID(#mfFont))
  
  AddWindowTimer(#mf, 0, 1000)
  BindEvent(#PB_Event_Timer, @ShowTime())
EndProcedure

Procedure ShowTime()
  Protected Time.s = FormatDate("%hh:%ii:%ss", Date())
  SetGadgetText(#mfTime, Time)
EndProcedure
