[Tim at Loddon]

Please posts some blocks and an example of your cab so we can help.

[khaled alamer]

Hi Tim,

Please open  attached aia.Thank you so much 

[Taifun]

If you are asking for help, I recommend you to make it as easy for others to be able to help you ...

You probably will get more feedback then...

which means in your case post a screenshot of your relevant blocks...

To download the aia file, upload it to  App Inventor, open it, do some bug hunting for you, etc... this takes time, and most people will not do that...

Thank you.

It doesn't works. Please help.

Thx a lot

[Taifun]

you might want to provide a screenshot including Do it results

Taifun

[khaled alamer]

There is no result message comes after click download button

There is no result message comes after click download button

instead of the download option use a screenshot tool to take a screenshot including Do it results, see also below

Taifun

Capture the blocks on your browser screen as follows:

======================  Screen Capture  +++++++++++++

On Windows  Ctr + PrtScn  keyboard keys pressed at same time copies an image of the screen to the Windows Clipboard.  Open Paint and save the image by placing the contents of the clipboard into Paint. Save the image to your desktop or another folder as a png or jpg file.  On Win 7 and above you can use the Snipping tool (in Accessories) to capture an image of blocks directly from the screen.  Capture what you need and Save the file to a folder on your PC.

On a Mac,  command-shift-3 (whole-screen) or command-shift-4 (drag a rectangle) to take a screenshot. The image file will appear on your desktop. 

Once you have the image of your blocks, you can drag them to MS Word and I think you can drag the image to PowerPoint.

Hi Zac,

I am trying to use nested picker on this project, but I don't have enough knowledge to complete it.Please help.

Thank you so much.

How to create a nested listpicker

A very good way to learn App Inventor is to read the free Inventor's Manual here in the AI2 free online eBook   http://www.appinventor.org/book2 ... the links are at the bottom of the Web page.  The book 'teaches' users how to program with AI2 blocks.

There is a free programming course here http://www.appinventor.org/content/CourseInABox/Intro  and the aia files for the projects in the book are here:  http://www.appinventor.org/bookFiles  

How to do a lot of basic things with App Inventor are described here:  http://www.appinventor.org/content/howDoYou/eventHandling  .

Also do the tutorials http://appinventor.mit.edu/explore/ai2/tutorials.html to learn the basics of App Inventor, then try something and follow the

 Top 5 Tips: How to learn  App Inventor

You will not find a tutorial, which does exactly what you are looking for. But doing the tutorials (not only reading a little bit) help you to understand, how things are working. This is important and this is the first step to do.

When I open the list Picker, there are two Readers and each Reader has many different chapters that is Mp3 sound,  but the problem is that when I click on the list picker it comes the same result.

[zac]

See my attachment for the update. 

Now you need a new CSV for each "reader" to include his URL.

In my version, when you add a new CSV file, the name of the CSV files must be "xReader_URL", where (x) is the selectionIndex of the reader

[khaled alamer]

Thank so much Mr.Zaki!

I really appreciate of your helping me to complete the apps in excellent work and easy to use. Is it possible to remove Chapter listPicker and just open Sura ListPicker directly to be easier because I don't need Chapter at all.

Thank you so much!

[zac]

No problem brother.

Yes, you can. see my example.

I'm waiting to see your finished app, keep building :)

[khaled alamer]

Thank you again Mr.Zaki.

Would you please help me to add some blocks to be easy for the user to download the sound into SD Card and listen to that again without download it again.

Thank you a lot Mr.Zaki

[khaled alamer]

Hi Zaki,

Thank you so much for your help.

Now it is working.

Good luck & Best wishes!

[khaled alamer]

Hi Zaki,

I am really sorry to bother you my brother.

I am still facing the same problem after download sura.

It doesn't read the  selected sura for selected reader as I want.

Please help if you don't mind.

Thank you so much.

[zac]

Can you please provide a screenshot of your problem. 

[khaled alamer]

Hi ZAki,

Attached is a screenshot of my block. Please help.

Thank you

[khaled alamer]

Hi Zaki,

Finally, it works very well by using this block. but is it possible to use csv instead of using global for two readers?

Thank you a lot for help.

[khaled alamer]

Hi Zaki,

Again it doesn't work as I excepted. Please help:)

I want to play the sound after downloaded in SD card.

Thank you 

[zac]

Did you specify the correct path of the downloaded file? 

In the "IF" statement, the file will play only if the path is exist. 

In addition, you need to move some blocks as in my attached.

[khaled alamer]

Hi Zaki,

Yes, the path is correct.

[zac]

After you select, "Do it" to see if the path is correct (exists). 

[khaled alamer]

Hi Zaki,

I do it, but the result is the same.

When I play any reader, I get the same result for both readers although I put the path correct. 

[zac]

You need to specify which reader is selected to do it

[khaled alamer]

That is a great!

Thank you so much Mr.Zaki

You are really a very helpful man I have never seen before and you deserve the paradise.

Good luck my brother!

[khaled alamer]

[khaled alamer]

Hi Mr Zaki,

Is it possible to build a block in order to download the sound directly without open black sound screen?

[zac]

Upload your files to your own hosting-space OR  to online cloud that support direct link download. 

See if this works:

If you are using Chrome browser do like my attachments and change your CSV to the new links.

[khaled alamer]

Can you please send me any link about online cloud to know more about how to do that?

I am so interested to know more.

Is it free of charge or limited?

[khaled alamer]

Can you please give me more detail about:

See if this works:

If you are using Chrome browser do like my attachments and change your CSV to the new links.

I am sure I will accept what you are suggesting to me.

Thx

[zac]

1.

Just follow the steps for each Sura to get its direct download link. These steps are for the chrome browser. 

https://drive.google.com/file/d/0B6tIqrqfHzcnc0hzMFFDU3lfMFE/view?usp=sharing

2. 

3.

 And then replace the old links with the new ones you obtained.

[khaled alamer]

Hi Zaki,

I have done all steps but there is a message shown when It starts download sura.

[zac]

did you copy the right link. See if the below link works.

https://doc-08-4o-docs.googleusercontent.com/docs/securesc/8suimes101pmauq63vnabk8urcdiavvf/bhhmu06p298ona2d0157fphg5usbfadg/1492668000000/14009648150512800476/00028038951488266200/0B6tIqrqfHzcnc0hzMFFDU3lfMFE?e=download

[zac]

This website will convert your drive link to a direct download link http://gdurl.com/

1.  

2.

[khaled alamer]

I think this link will not download Sura directly there is also the same message shown up.:

Google Drive can't scan this file for viruses.

I think to let it as it is, that is much better than get too much hard work :)

[zac]

OK don't use the website. Use the first steps I showed you.

I tested it. It downloads without shown the message on the phone.

[khaled alamer]

I am sorry to bother you. Actually, I tried but unfortunately it couldn't be loaded directly. 

[khaled alamer]

I am trying to pick sura from csv but fortuneteller I can't build that one in correct way. 

[khaled alamer]

Hi Zaki, I have done the same way for each reader but after 5 readers,It couldn't compile. There is error. Is it possible to simplify the way in order to repeat for each reader instead of building a very long blocks.

Thank you.
