Saving files from Android devices to external servers has presented
challenges in the past. This is a SIMPLE approach. It assumes you are
running LiveCode server on the server site. Installing this requires a
careful procedure described elsewhere (see
https://livecode.com/resources/guides/server/ and references therein). The
on-rev site runs this software, so posting this file to the on-rev server
should be enough (untested).
On the server, you have a file saveMyFile.lc:
put $_POST["tFileName"] into tTheNewFileName
put $_POST["tFileText"] into tFileText
put tFileText into URL("file:"&defaultFolder&"/"&tTheNewFileName)
This will place the new file in the same folder as the saveMyFile.lc.
On the Web-connected Android app you have something (like a button)
executing this script:
put (line 2 of fld "theFileName") into tFileName
put URLencode(tFileName) into tFileName
put fld "RecordFile" into tFileText
put URLencode(tFileText) into tFileText
post ("tFileName="&tFileName&"&tFileText="&tFileText) to URL "
While the security of this approach is poor and there is no error checking,
it does get you started. Because LC allows easy manipulation of text,
saving text files often beats saving in databases.
It is a GREAT DEAL EASIER to accomplish this simple task in desktop apps
using statements like put thisFile into URL (this location). You don't have
to manage the server side (assuming writing permissions are set properly).
Methods using other server-side approaches (like php) are described
