TinyDB. Restore after app reinstall or wipe date

[Korneich]

Good day to all!
I have encountered a seemingly simple problem - saving a TinyDB backup and restoring it after reinstalling the application or deleting its data. It seems that I have already gone through the circle of different extensions several times: ETinyDB, MFile, TinyDBx...
Please - tell me how I can implement the ability to periodically save a TinyDB backup to a file and then restore it after reinstalling the application.

When restoring after clearing data - such an error

Thanks in advance for your help!

You will need SAF to access non media files, which your app does not own

Some basics on Android storage system

From an Android point of view there are an → Internal Storage and an → External Storage . 1.

I would be grateful if you could tell me how to implement this. I am a beginner and I can't figure out such a large number of blocks.

Use the FilePicker to allow the user to select the file, then use File component to read the file's content. Then give it to ETinyDB

[Korneich]

thank you, I will try

You can do this without extensions or files too.

TinyDB has a block that can dump its contents into a dictionary.

Dropping a dictionary into a sharing component text stream block can feed the contents cross platform to your email or text editor apps as a JSON text string.

Coming back, the AI2 textbox should be able to accept an Android paste of a text copy done from the email client or wherever you saved the JSON text string.

The web component has a block that can decode the JSON text into a dictionary.

There is a for each key and value loop block that can traverse the dictionary.

Loop through the dictionary and reload TinyDB from the dictionary, using the keys as tags, value for value.

I had a typo in my URL, so the download failed. This version is more transparent: [blocks (1)] TinyDB_web_paste (1).aia (3.0 KB)

You're not the first to ask for this.

Here's the sharing code:
