The emulator said "The application find root (process awaken.findRoot0 has stopped unexpectedly.Please try again"

 

[Erel]

You should check the logs. There should be an error message there.

I did not understand what's the issue

Sorry

I'm sorry for the copying all error..
someway I heard Erel then my program can run.
Now, I get a problem..Here:
My program had two activity.
In first activity(Main), an edittext will get a value.Let say A.
Also,in second activity(Submain), an edittext will get a value.Let say B.
Value A will make a loop to call secondactivity like this

For i = 0 To maxpowr 'maxpower is A
StartActivity(Submain)
a = Submain.coefficient2 'coefficient2 is B
cofx(i) = a
Next

Then,the secondactivity will get a value B.
When I press next button, I want the value store in the array above and then continue the looping.

Please reply me..I had post my code in previous reply

First of all, it is difficult to find the problem without filtering the logs.
Anyway, you start a new activity from inside a loop, obviously wanting to get data to fill the first activity. Now, I think this is wrong, and probably the cause of your problem. I would suggest that you enter the coefficients in a simple panel, at your first form. Something like this:

'Activity module
Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.

End Sub

Sub Globals
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.
Dim equationmaxpower As EditText
Dim findrootButton As Button 
Dim maxpowr As Double
Dim coEfficient As Double
'Dim resultss As Double
Dim i As Double
Dim cofx() As Double
Dim coDfx() As Double
Dim a As Double
Dim maxpowrDfx As Double
Dim pn As Panel 
Dim btnNext As Button 
Dim coEfficientText As EditText
Dim coEffCounter As Int
End Sub

Sub Activity_Create(FirstTime As Boolean)
equationmaxpower.Initialize ("")
Activity.AddView (equationmaxpower,0,0,50%x,10%y)
findrootButton.Initialize ("findrootButton")
findrootButton.Text="set coeff"
Activity.AddView (findrootButton,0,20%y,50%x,10%y)
pn.Initialize ("pn")
btnNext.Initialize ("next")
btnNext.Text="Next"
coEfficientText.Initialize ("")
coEfficientText.Text=""
pn.Visible =False
Activity.AddView (pn,0,0,50%x,40%y)
pn.AddView (coEfficientText,0,0,40%x,10%y)
pn.AddView (btnNext,0,20%y,40%x,10%y)
End Sub

Sub Activity_Resume

End Sub

Sub Activity_Pause (UserClosed As Boolean)

End Sub

Sub findrootButton_Click


If equationmaxpower.Text = "" Then
    Msgbox("Insert a value","")
    Return
Else
    If equationmaxpower.Text = 0 Then
        Msgbox("Insert a value more than 0","")
        Return
    Else
        Try
            ' you don't need this. you've checked already for that above
            'If Not(equationmaxpower.Text = "") Then
            maxpowr = equationmaxpower.Text
            coEfficient = maxpowr + 1
            Dim cofx(maxpowr+1) As Double
            Dim coDfx(maxpowr) As Double
            coDfx(0) = 0
            i=0
            btnNext.Text="Enter coeff" & (i+1)
            pn.BringToFront :pn.Color=Colors.Blue 
            pn.Visible =True
            coEfficientText.RequestFocus
        Catch
            Msgbox("enter a number","error")
        End Try
    End If
End If
End Sub



Sub next_Click

If coEfficientText.Text = "" Then
    Msgbox("Insert a value","")
Else
    Try
        cofx(i)= coEfficientText.Text
        If i<maxpowr-1 Then
            coDfx(i)=cofx(i)*(maxpowr-i)
        End If
        i=i+1
        If i<=maxpowr Then
            coEfficientText.Text=""
            coEfficientText.RequestFocus
            btnNext.Text="Enter coef" & (i+1)
        Else
            pn.Visible =False
            ' from here, proceed to whichever sub you want to go on
            ' just an example
            Dim tempS As String 
            tempS=""
            For j=0 To maxpowr
                tempS=tempS & "coeff "& (j+1) & " = " & cofx(j) & CRLF
            Next
            Msgbox(tempS,"finished")
        End If
    Catch
        Msgbox("enter a number","error")
    End Try
End If

End Sub

Thnks

I have to thank you for the great reply..I am just very beginner and only had some little knowledge in vba and java..Sorry. Can you give link of tutorial to understand the code of android better.
Your code is work and thanks for reply but I still thinking doing it in two activity..Can it be done..?

Sure it can be done. You have to load the code of the panel, to your new activity. When you finish entering data, you start again the previous activity, setting a boolean flag to true, to notify the previous activity that data arrived. (I think there are other ways for this too, others may help you more).
I think you should start from Klaus beginner's guide, here: http://www.b4x.com/forum/basic4android-getting-started-tutorials/9578-beginners-guide.html#post53042

Thnks

I will look into it..
