Android Question [SOLVED] Why Activity_Create is executed 2 times ?

vbmundo · Sep 6, 2016

Hi,

I don't undertand why for every Activity, Android or B4A run 2 times Activity_Create..

I put code there, and this code is executed 2 times.

Regards

DonManfred · Sep 6, 2016

Only one time for me. I put a log fo see it...

Maybe try it in a new project and see if it happens the same.
Try to reproduce it in a small project and upload this project.

vbmundo · Sep 6, 2016

I don't understand.. in my 2 APPs... for every Activity I see

** Activity (Anyone) Create, isFirst = true **
xxx
xxx
xxx
** Activity (Anyone) Create, isFirst = false **

And as Layout is loaded in every Create instance, I need to repeat all code

Regards

DonManfred · Sep 6, 2016

What is the xxx part? showing other activities or doing downloads or what happens there?

vbmundo · Sep 7, 2016

Look Don,

this is my log

And this is my Code

B4X:

Sub Activity_Create(FirstTime As Boolean)
       Activity.LoadLayout("ResultadoSELECT")
    f.Initialize
    Telefono.SetScreenOrientation(0)
    Activity.Title=" Query Results"
    BotonSiguiente.Visible=False
    BotonPrevio.Visible=False
    Barra.SetAsActionBar
    Barra.InitMenuListener
    ABHelper.Initialize
    ABHelper.ShowUpIndicator = True
    Activity.AddMenuItem("Save Query","GrabarQuery")  
    Activity.AddMenuItem("Show the SQL Statement","ShowSQL")
    Activity.AddMenuItem("Export","Export")
    MySQL.CorroSQL=True
    If FirstTime=False Then
           ProgressDialogShow2("Running SQL",False)
        CallSub2(MySQL,"LeoMySQLTables",CreateMap("TextoSQL":MySQL.TextoSQL,"Activity":"ResultadoSELECT","Modulo":"TablesSQL"))
    End If
End Sub

Sub Activity_Resume
End Sub

Sub Activity_Pause (UserClosed As Boolean)
    If UserClosed Then
        StateManager.ResetState("ResultadoQUERY")
        Telefono.SetScreenOrientation(-1)
        Activity.Finish
    Else
        StateManager.SaveState(Activity, "ResultadoQUERY")
    End If
    StateManager.SaveSettings
End Sub

all MySQL calls, are using your lib.

SetScreenOrientation should only be used if you want to change the orientation at runtime. You should instead change the #SupportedOrientations attribute.

Thanks Erel,

But I need to set some Activitys with PORTRAIL and just one LANDSCOPE

I see that #SupportedOrientations is for the entire APP

How can I set ONE only Activity as LANDSCOPE but without runs Create Sub 2 times ?

Regards

DonManfred · Sep 7, 2016

In manifest

This will change the activity video to landscape only

B4X:

SetActivityAttribute(video, android:screenOrientation, "landscape")

You only need to read my previous POST in your MySQL Lib and you will a GOD for me... jeje

Hi Pablo,

if you do not want to change the manifest manually, you can do this in the activity you want landscape:

B4X:

Sub Globals
Dim Phone1 As Phone
' .............
' .............
' .............

Sub Activity_Create(FirstTime As Boolean) 
  Phone1.SetScreenOrientation(0) ' landscape
' .............
' .............
' .............

Sub Activity_Pause (UserClosed As Boolean)

if UserClosed then Phone1.SetScreenOrientation(-1)  ' unlock screen rotation
' .............
' .............
' .............

regards

Yes Jesus,

All my Activitys has this SetScreenOrientation() statement.

but if you read this thread you will understand that the command is executed, the SUB Create running again ... which makes very little-productive

You can test this.. include this statement in your CREATE sub and see your log section.

NOW... I have this settings in the Manifest and all runs more faster because my CREATE Subs runs once

vbmundo · Sep 8, 2016

Thanks Luca !!

Hi Pablo

All my Activitys has this SetScreenOrientation() statement.

That is the mistake, only you would have to put in which is landscape.

How can I set ONE only Activity as LANDSCOPE but without runs Create Sub 2 times ?

but if you read this thread you will understand that the command is executed, the SUB Create running again ... which makes very little-productive

It is logical that reenters Create, are forcing a change of orientation, although this change is by code.

I just said if ...

f you do not want to change the manifest manually

Not really Jesus,

Because, If you have a Layout that only works in Portrait, you must to set this value as the unique possible value.

Yes that always works, but in your code you add this:

B4X:

Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("ResultadoSELECT")
    f.Initialize
    Telefono.SetScreenOrientation(0)  ' <-- This causes rotate and re-enters in create

Yes, now I have all in Manifest and works fine.
