Hello friends,

we are going to get the content of the TinyDB using the com.KIO4_Terminal.aix extension that you can find in ...

Using LINUX commands in App Inventor. Extension

Hello friends, with this extension we are going to use some LINUX commands. com.KIO4_Terminal.aix With this block we can copy files from the assets to SdCard. This block only works with the compiled app (Build). It needs AskForPermission = WRITE_EXTERNAL_STORAGE [extension_terminal3] [shell_permiss] oooooooooooooooOOOOOOOOOOOOOoooooooooooooo With this block we can copy files from the assets to the internal cache directory of the same application. We will get the address of the accessi…

0.- To do this study the application must be INSTALLED.

1.- We create three TinyDB:
TinyDB1 ........ Namespace: TinyDB1
TinyDB2 ........ Namespace: TinyDB1
TinyDB3 ........ Namespace: Tiny_Three

• TinyDB1 and TinyDB2 are the same database, the same file, because they have the same Namespace: TinyDB1. Both will be the TinyDB1.xml file
• TinyDB3 is a different database, a different file, because it has a different Namespace: Tiny_Three. The will be the Tiny_Three.xml file
  

2.- In our app, in addition to the TinyDB, we will upload the file my_file.txt to the assets.

3.- Using the "AssetsToCacheDir" block, we will copy the file into the Cache directory of the same app and obtain its address:
/data/user/0/appinventor.ai_juan.get_tinydb/cache/my_file.txt
We also get:
/data/user/0/appinventor.ai_juan.get_tinydb/cache
/data/user/0/appinventor.ai_juan.get_tinydb/

4.- When we place TinyDBs, the shared_prefs directory is created with the .xml files corresponding to the TinyDBs

5.- The name of those files is the Namespace, in our case TinyDB1.xml and Tiny_Three.xml

1.- We create three TinyDB:
TinyDB1 … Namespace: TinyDB1
TinyDB2 … Namespace: TinyDB2
TinyDB3 … Namespace: Tiny_Three

• TinyDB1 and TinyDB2 are the same database, the same file, because they have the same Namespace: TinyDB1. Both will be the TinyDB1.xml file
• TinyDB3 is a different database, a different file, because it has a different Namespace: Tiny_Three. The will be the Tiny_Three.xml file

??? TinyDB2 should be namespace TinyDB1 ?
