Alright I have been working on this all day, and am on the brink of screaming
this is the code I am at, at the moment, after a whole bunch of different variations, from looking at a bunch of different forms.
I would like for it to save as a .json file but I will settle for a .txt file
at the moment the error I am getting is Error 2104: Cannot write to file /storage/emulated/0/Download/dexa.txt
this is honestly a blessing because for the longest time it did nothing at all, flashing no error or it just crashed the app, please please please help
You are using the constant 'tag' as your dictionary key for each and every TinyDB value.
That overwrites them all except for the last one.
I don't touch file creation.
I don't need the aggravation.
Here's a workaround to try:
Hopefully, the entire TinyDB content, tags and values, would be marshalled as a dictionary and then into JSON text, then sent out to Android for any willing text receiver app like a Notepad app.
I tested this on my phone using the Companion, and sent the shared output to GMail.
Here's what I received:
{"-73.62+40.64":["rake the grass "],"40.64+-73.62":["rake the leaves ","rake the leaves ","rake the grass "],"AllTasks":["rake the leaves ","rake the leaves ","rake the grass "],"DEST":["Spaceship Earth","Tree of Life","Sunset Blvd","swamp "],"DESTLL":["28.375429449089623, -81.54943227767946","28.357114670505815, -81.59065246582033","28.358304283031128, -81.55986070632936","28.38306,-81.58382"],"ITEMSTOBUY":["MORE BOOKS ","FRUIT ","AI2 BOOKS "],"MyImages":["file:///storage/emulated/0/Android/data/edu.mit.appinventor.aicompanion3/files/Pictures/app_inventor_1735246140161.jpg","file:///storage/emulated/0/Android/data/edu.mit.appinventor.aicompanion3/files/Pictures/app_inventor_1735246238097.jpg"],"MyUserName":"ABG phone ","TARGETVA":"File","myUniqueID":1735955076924}
It's a JSON representation of my phone's Companion app's TinyDB, with all the cruft it has accumulated from testing other peoples' apps.

That was way to easy, thank you so much, I just got it working, I was able to email it to myself, and ya now I can do whatever I want to it.
Now I just gotta figure out how to have the app receive a "file" and reimplement the data.
@ABG by chance can you help me figure out the rest of my code, if not i completely understand. the thing I am stuck on is now taking the text I shared and implementing back into the code, so app users can basically share their lists to eachother, I have been again fighting with this for quite a while, trying many different things
I believe all I need to change is here
however there is a good chance this will become a problem to
but just in case here is my entire code
If you are able to help, it is much appreciated, thank you.
Hi
It would be easier on our side if you uploaded your Project (.aia) file.
Also upload example data that you are storing in TinyDB1.
I'm going to leave you with ABG as he already has a feel for how your Project works/should work. Take a bit more care in how you name Components, Blocks and Variables.
For example saveddata is a dictionary: dictionarySavedData
Give Button5 a meaningful name etc.
When you do this, it is easier to read the code.
It's going to be a while until I can get to my PC.
I recommend using the web get to grab the file from wherever shared cloud file you saved the JSON.
Copy the URL and paste it into a textbox at run time for the web get.
The keys the JSON dictionary are the TinyDB tags.
After decoding the JSON as dictionary, use the
For each in dictionary
Block to traverse all the key/value pairs while storing each in the corresponding TinyDB tag
Here's a downloadable link to a text file with my JSON:
ABG_TinyDB.json (775 Bytes)
The link to it is
https://community.appinventor.mit.edu/uploads/short-url/oTmNjQHpVZHbz67K1jYpBpel9Ai.json
If I were to browse this post on my phone and copy the link, hopefully I could paste it into a text box and import from that link.
Here's sample code to do the import, once I have the URL:
TinyDB_web_paste.aia (2.7 KB)
Note: I tested on my phone, and the completion message noted only 2 tags/values updated. I need to investigate further.
I had a typo in my URL, so the download failed.
This version is more transparent:
TinyDB_web_paste (1).aia (3.0 KB)
alright thank, ill try this, in theory can that link be a google drive link.
and just incase you wanna look closer here is the example data being transferred
{"":["entry1","entry2","entry3"],"entry1":"/storage/emulated/0/Android/data/edu.mit.appinventor.aicompanion3/files/Pictures/_app_inventor_image_picker/picked_image4503833253438619939.jpg","entry1_desc":"entry1 description ","entry2":"/storage/emulated/0/Android/data/edu.mit.appinventor.aicompanion3/files/Pictures/_app_inventor_image_picker/picked_image2146989564047454810.jpg","entry2_desc":"entry2 description","entry3":"/storage/emulated/0/Android/data/edu.mit.appinventor.aicompanion3/files/Pictures/_app_inventor_image_picker/picked_image8380914919553078739.jpg","entry3_desc":"entry3 description"}
and here is my codes aia file
Dex.aia (9.2 KB)
An empty tag is asking for trouble.
tags and keys must be nonblank text.
Lists make for trouble as tags.
I'll give you time to debug using the Do It facility.
Apply Do It to every value going into or coming out of a block to see how your data looks like.
Alright I went into my .json file deleted this part
and I was able to figure out the link
I also believe I got the code working the only thing that wasn't readded was the pictures which is fine, I mainly wanted the text to be transferable.
Like i said I think I got it working, I haven't run a full test but hopefully it is and everything from here on out will be duplicating code and aesthetics, thank you so much for your help it has been much appreciated.
here is the updated snippet and my entire code
