Install data files from apk

After quite a bit of searching it seems there is no easy way to install data that have been included in apk.
It is recommended to use assets in apk and then the installed program would use java functions getAssets().open("path/file.ext") or getResources() to access the data stream in apk
I can't find getAssets() or getResources() in Harbour or QT.
I would rather not have to download separate Data, PRG, and other files during installation.

Gale,

I have just emailed Priptpal Bedi (HbQT developer) to know if GetAssets() is supported in HbQT.

I just realized that an APK is a ZIP file, so if we could get the path of the APK then we could extract the
files from the APK itself using Harbour :-)

I just tested this code from FiveTouch:

Code: Select all

#include "FiveTouch.ch"
      
function Main()
      
   local n

   for n = 1 to 20
      MsgInfo( QStandardPaths():StandardLocations( n ):Value( 0 ) )
   next

return nil      
But not sure if one of the returned values is the one that we are looking for

Pritpal has published some code to do it:

https://groups.google.com/forum/#!topic ... E60mMvHXdc
FUNCTION __testRDD()
LOCAL dir_, cQrcFile, cPath

cPath := QStandardPaths():writableLocation( 9 ) // 9 == the only one which works, tested with 1.2.3 etc.

ft_mkDir( cPath + "/" + "accmix" ) // it will fail if "accmix" already exists

IF ! hb_fileExists( cPath + "/" + "accmix" + "/" + "ACCFBASE.MXD" )
cQrcFile := hb_base64Decode( __hbqtLoadResource( ":/tables/ACCFBASE.MXD" ) )
hb_MemoWrit( cPath + "/" + "accmix/ACCFBASE.MXD", x )
ENDIF
USE ( cPath + "/" + "accmix/ACCFBASE.MXD" ) VIA "DBFCDX"
dbGoTop()
hbqt_debug( FieldGet( 1 ) )
USE
dir_:= Directory( cPath + "/" + "accmix/*.*" )
hbqt_debug( cPath + "/" + "accmix/*.*" )
AEval( dir_, {|e_| hbqt_debug( hb_ValToExp( e_ ) + Chr( 10 ) ) } )

RETURN NIL



In the .qrc
========
<file>tables/ACCFBASE.MXD<file>

The binaries must be stored in .qrc hb_base64Encode()ed.


As Android is a Linux kernel, make sure that file/folder names are case-sensitive.

QStandardPaths():writableLocation( 9 ) gives a permanent place to
read/write whatever you want. So create a unique folder inside there
and organize the files in subfolders. This will also ensure that whenever
you ship another version of your app, the data is not lost.

I saw that. I will be working on it this weekend.
Thanks.

In QT Creator project file:

COMMON_DATA.path = /assets
COMMON_DATA.files = $$PWD/FiveTouch.ch
COMMON_DATA.files += c:/harbour/include/hbclass.ch
COMMON_DATA.depends = FORCE
INSTALLS += COMMON_DATA

From our source:

QFile( "assets:/FiveTouch.ch" ):copy( "FiveTouch.ch" )
MsgInfo( File( "FiveTouch.ch" ) ) // shows .T.
