Won't flag you this time, but you need to be patient, and wait for the right person to come along who can help you with your chat app.
Thank you very much for that 
Ok . Can you ( Help me ) ?
We cannot read your blocks.
In the Blocks editor, right click on white space and select Download Blocks as Image, then upload that here.
From your link in your second post, you have already been provided with an example of a chat app by @Kevinkun.
As a suggestion, do not try to send audio or video between devices. Use an online location to store your media, and then share the links.
Hello , Tim . Thank you for your big patience . Excuse me if I answer to you only now , but in my country was night when you replied to me , so only now I see your answer ...
Thank you . Here you are ...
Yes , and this is an interesting example of how to share images and audios ... but I cannot understand some things of the app , because are in chinese .
It will be a great project if it will be a complete app translator ( It could translate the text and the components of the app ... )
Anyway , I can try to understand how to use that good audio sharing
P.S. :
Thank you for that suggestion , and I thought about it , only that it would be very uncomfortable for the users to put their images in Google Drive or some other file sharing systems , if their are in an another app ... ( In WebWiewer you cannot upload or download files ... )
There is nothing in Chinese in the example aia project provided?
Then you will need to find/create a peer to peer (device to device) sharing system for over the internet. You may be able to use UDP, or have a look at WiFi Direct but you will need an extension and/or further android code for that.
But I see you are already using cloudDB - so do not understand what your issue is....
You can use the webviewextra or customwebview extensions for that
But ... some notifications I saw that are in chinese ...
If that functions with two phones very distant , it's Ok ( Example : One in America , one in Italy ... )
But my app is also social ( Like Facebook ) . Really , the " Social " part I use it like a beta tester , and then the " Social's part " features become a part of the functions in the private chat
Thank you ! I'll test it , but I prefer a file sharing indipendential in the app .
Do you want that I explain you better how my app works ? ( If possible I'll tell you that in italian ... ) .
I can see what you are doing, storing data/binary files with base64. The data is only encoded and not encrypted, so anyone with access to the files can decode them.
And then I show the files with WebViewer, with a data:base64 link...
It works with small images, but not with large ones, videos, and audio.
What is to stop users who receive these media files from sharing them outside of the chat app. Have you got that covered off ?
A post was merged into an existing topic: Test php no result
Moved because it was off topic in this topic.
I only see one place with Chinese, and if you read the blocks carefully, it will only show up when you forget to input your content before you click 'Send' button.
Hello , Tim . Thank you for your patience . No , I didn't covered that off
Hello , Kelvikun . Thank you for your patience ( Again ) , and thank you . Anyway , your app has some material for audios , I guess . Now the problems are the videos
THIS QUESTION IS NOT ANSWERED ! 
I want a code , I said one code , blocks ... that send audio , images , videos and ... PDF's ( maybe ) !
Are 10 days that I wait !
No
From a quick review of your blocks in your chat app, it appears you are storing a video, an audio, or an image to a specific tag for each type (using a separate cloudDB for each as well). The only issue I believe I can see is that these media items will overwrite the previous one when a new item is stored.
Also, given you are using the default cloudDB store provided by MIT, you/users may come under the heading of a "heavy user" and be blocked... (due to the use of large files such as videos/audio/images)
Please try to remain polite when asking for further help, typing in CAPITALS is considered rude and shouting.
Execuse me ... where is and how can I activate the on-board translator ? 
You should see this icon:
in posts that are not in your language.
Alternatively, you should be able to right click on the page and select "Translate to ..." (in Chrome)
