Hello friends,
there are several ways to upload a file to our server: FTP, Postfile,... in this example we are going to convert the file into text using a Base 64 extension and upload that text using PHP.
You can download the extension com.KIO4_Base64.aix of:
In this example I will use 000webhost server
<?php
// Juan A. Villalpando
// kio4.com
// https://kio4.000webhostapp.com/dibujo.jpg
$datos=$_POST;
$contenido=$datos['contenido'];
$plainText = base64_decode(str_replace(array('-', '_',' ','\n'), array('+', '/','+',' '), $contenido));
$ifp = fopen( "dibujo.jpg", "wb" );
fwrite( $ifp, $plainText );
fclose( $ifp );
echo "Creo que ha subido";
?>
Podremos ver la imagen:https://kio4.000webhostapp.com/dibujo.jpg "

With this code you can set the name of the file.
<?php
// Juan A. Villalpando
// kio4.com
// https://kio4.000webhostapp.com/name_file.abc
$datos=$_POST;
$contenido=$datos['contenido'];
$nombre=$datos['nombre'];
$plainText = base64_decode(str_replace(array('-', '_',' ','\n'), array('+', '/','+',' '), $contenido));
$ifp = fopen( $nombre, "wb" );
fwrite( $ifp, $plainText );
fclose( $ifp );
echo "Creo que ha subido";
?>
Another example:
The Camera takes picture and upload to the server.
thanks both! taifun for redirect me to good tutorial and Juan Antonio you opened my eyes on split list item list
Hello all,
Vincent1:
new version of Android
I have modified the code, you can check if the new extension works: KIO4_Base64v10.aix , :
Edit:
If you are going to use this extension in Android 10 or higher , you must use the blocks that contain "ASD" , the BASE directory is:
/storage/emulated/0/Android/data/'namepackage'/files
that is, if in the CreateDirectoryASD block you write: /my_directory , it will be created in:/storage/emulated/0/Android/data/'namepackage'/files/my_directory
If you are going to use this extension in Android 9 or lower , you can use the blocks that contain "ASD" as I have indicated above, you can also use the blocks that do not contain "ASD", in this case the BASE directory is:
/mnt/sdcard
that is, if in the CreateDirectory block you write: /my_directory , it will be created in:/mnt/sdcard/my_directory
This extension also contains the GetApi and GetSdkCodeName blocks, with these blocks you can check the version of Android that the device has installed.

Tested in companion on Android 10 (genymotion emulator) and Android 11 (real device Google Pixel 4a)
This works OK
For a file in the assets / media folder, this works OK
Thank you Juan for your good work
I note the extension for 10+ doesn't overwrite the earlier extension. Can both extensions be used at the same time, to handle different android versions ?
Hi @TIMAI2 , thanks for testing the extension, I have taken your idea and joined the two versions of this extension, I have edited the previous post.

Hi Juan
Using the extension today to encode an image from assets (on Android 10). This works:
but the tooltip says to use two slashes // - which doesn't work.
Which one is correct ?

Yes, only for Android < 10.@Juan_Antonio
Does this app installed on Android 10 and 11 work?

Tested apk Android 10 and 11. Works OK. (Couldn't see if the directory intoASD was created in Android 11 due to Google lockdown, but created in Android 10, but no errors).
I guess we just need an if else block if we are working in development mode to access assets, in the MIT companion directory.
Thanks @TIMAI2 for testing it on Android10-11.
With double slash //gato.png works in development mode and installed.
- Image in asset to Base 64 and upload to web.
p327C_subir_archivo_imagen_Base64_ASD.aia (1.7 MB)
This example:
Converts an asset image to a Base 64 string, with block "FileToStringASD"
Show that string in a Label.
Convert that string to an image called: "/this_is_a_cat.png", save it in ASD, and show it in Image2
With block "PostText", sends string to web.
A PHP file converts that string to image: dibujo.png in web server.
You can look that image in a web page.
PHP code:
<?php
// Juan A. Villalpando
// kio4.com
$datos=$_POST;
$contenido=$datos['contenido'];
$plainText = base64_decode(str_replace(array('-', '_',' ','\n'), array('+', '/','+',' '), $contenido));
$ifp = fopen( "dibujo.png", "wb" );
fwrite( $ifp, $plainText );
fclose( $ifp );
echo "Creo que ha subido";
?>
- PICK Image and convert to Base 64, upload to web. PHP.
p327C_subir_archivo_imagen_Base64_ASD_PICK.aia (1.7 MB)
We can explorer and PICK an image file with ActivityStarter:ActivityStarter1.Action = android.intent.action.PICKActivityStarter1.DataType = image/*
We get ResultUri, example:content://com.mi.android.globalFileexplorer.myprovider/external_files/gato.png
Using the UriToPath block, we convert that uri to the path of the file:/storage/emulated/0/gato.png
We remove the base of that address to obtain /gato.png
That file to string: FileToString block.
That string to file in ASD: StringToFileASD.
With PostText upload string to web.
PHP file receives the string and converts it to the file dibujo.png
Show that image in a web page.
- PICK Image. Copy in ASD. Convert to Base 64. Upload to web. PHP.
Can anyone check if this app works installed on Android 11 ? Thanks.
