I've got a problem with the Colored Dots tutorial.

[Ryan McCarthy]

I'm having a problem with the Colored Dots app I created, I followed the tutorial exactly, I made all the blocks, I double checked everything and it was just as the tutorial said it should be.

The problem is that when I try to test it on the Companion App, the whole thing is off screen and unusable.  I'm not sure if I did something wrong or it just doesn't work on the Companion but I need help.

You can try to install the App via apk:

1st: Click Build>App (provide QR Code for .apk)

2nd: Wait for the Barcode and scan it (if you do not have a QR-Code Scanner, you can scan it with the Companion)

3rd: Install the App and try it out

Er....... Now i don´t know what the problem is it. I have tested the app with the aia file (you sent me), but i have the same problem.

Can one help us?

what exactly means " the whole thing is off screen and unusable. "
can you provide a screenshot, so everybody is able to understand, what you are talking about?

I can't provide a screen shot from my own version but I post the screen shot from the tutorial it self to give an example.

So it looks like the picture below except the layout looks like it has been scrolled to the right and is mostly off screen. I can only see the erase button, pressing erase does nothing.

Are you using a Fixed or a Responsive screen Sizing.  Look at the Screen in the Designer and low in the right select Responsive if Fixed is selected.

This may solve your problem.     OR

did you

HorizontalArrangement

Layout

HorizontalArrangement1

Holds the following 4 labels:

Set Width to Fill Parent and AlignHorizontal to Center

Canvas	Drawing and Animation	Canvas1	Shows dots at the places you touch	Set the width to Fill parent and the height to 300 pixels
HorizontalArrangement	Layout	HorizontalArrangement2	Holds the following 2 Buttons and ListPicker	Set Width to Fill Parent and AlignHorizontal to Center

I can't provide a screen shot from my own version

why can't you provide a screenshot?

see here how to do it https://www.google.com/search?q=android+screenshot

I now looked at your project, there were 2 bugs in Screen1

1) you created an endless loop

2) the name of the other screen in your project is ColorPallete and not Brush_Picker...

3)

there was an empty socket in one of the blocks in the other screen and you should call the limitrange procedure there...

there might be more bugs in that screen...

I'm doing this as a class assignment and the tablet I use the companion on is at my school, I did download the companion on my phone but I don't have my phone with me.

So for 1 does the arrow mean I should put it under the "add items to list" block and for 3 are you saying that I should have it call limit range or that a shouldn't?

[Ryan McCarthy]

I had it on Fixed sizing, I switched it to Responsive like you said but I won't be able to test if it worked until Monday (I'm doing this as a class assignment and the tablet I was using to test it out is at the school, plus I don't have my phone with me to use the companion app on)

I'll let you know if it worked.
