Please use File/Export As Zip to create a zip file with your project, it will omit most of the Objects folder and the AutoBackups folder.

You can't 'keep' a toast message, it does what it does. I would suggest you add a label to the layout and put the desired text in that label (and clear it when the touch is released). Detect the down/up touch actions as @Erel explained in this post: https://www.b4x.com/android/forum/threads/panel-touch-action.12255/#post-68839

Hope this helps!

Before you go any further you need to understand how this forum works. This is outlined in this post at the top of this forum page. In particular always start a new question in a new thread, and use the code tags (</> in the menu above) to post your code example.

Please use File/Export As Zip to create a zip file with your project, it will omit most of the Objects folder and the AutoBackups folder. It will also result in a zip file <512Kb and you'll be able to attach it straight to the post.

Your 'detect' code is wrong:
- 'a And d' performs a logical 'And' on these values and results in a Boolean (True or False), and you want to detect the condition 'both values are 1'
- your first test was 'If a = 1'; if that condition was satisfied, you'd never reach e.g. the 'And d = 1' bit

It should be:

B4X:

Sub detect

    If a = 1 Then
        If c = 1 Then
            Log("Go front left")
        Else If d = 1 Then
            Log("Go front-right")
        Else
            Log("Go front")
        End If
    Else If b = 1 Then
        If d = 1 Then
            Log("Go reverse-right")
        Else If c = 1 Then
            Log("Go reverse-left")
        Else
            Log("Go reverse")
        End If
    Else If c = 1 Then
        Log("Go left")
    Else If d = 1 Then
        Log("Go right")
    Else
        Log("STOP")
    End If
            
End Sub

The attached version makes your code more compact (and elegant ) and was exported as zip (making the zip only 10Kb).

In Designer, these changes were made too:
- set the 'Tag' property for the 4 panels to 'Left', 'Right', 'Front', 'Reverse'
- changed the 'Event Name' property for the 4 panels to 'k' so that they share the same event

Hi, walt61.
Thanks a lot for your answers and support.
I finally made my own control app for my wifi remote car and here is the most stable version of my app.
I send it for you to thank you and see my app. I create two link of this file in my google drive because it's uploaded twice in a same time and I couldn't understand which one is the real file.
first link
second link
And the library I used to create some of the control's mode.
