LAMW: TEnvDirectory paths
« on: September 11, 2017, 02:32:16 pm »
Unless I am doing something wrong, this is what I get using jDownloadManager component with the TEnvDirectory paths.
I am using latest svn:

dirSdCard - DOES NOT WORK, goes to /Downloads
dirInternalAppStorage - DOES NOT WORK, goes to /Downloads
dirDatabase - DOES NOT WORK, goes to /Downloads
dirSharedPrefs -  DOES NOT WORK, goes to /Downloads

dirDownloads - Works! goes to /Downloads
dirDCIM - Works! goes to /DCIM
dirMusic - Works! goes to /Music
dirPictures - Works! goes to /Pictures
dirNotifications - Works! goes to /Notifications
dirMovies - Works! goes to /Movies
dirPodcasts - Works! goes to /Podcasts
dirRingtones - Works! goes to /Ringtones

P.S. jDownloadManager component works really well apart from the above issues!

Really keen to get this working ( specifically dirSharedPrefs ), looking to send my app to the Play store soon.  :)

Getting this:
dirSdCard: /storage/emulated/0/storage/emulated/0
dirInternalAppStorage: /storage/emulated/0/data/data/com.your.packagename/files
dirDatabase: /storage/emulated/0/data/data/com.your.packagename/database
dirSharedPrefs: /storage/emulated/0/data/data/com.your.packagename/shared_prefs

com.your.packagename is correct package name though!
I think /data/data/ should be /Android/data/ ?
I might have a go at fixing this myself  :)

Thank you jmpessoa (again!)

No.  "/data/data/" is Ok!

Question 1:

dirInternalAppStorage
dirDatabase
dirSharedPrefs

are internal app storages! 

So,  only your application can "read" and "write" them...

Question 2: Can jDownloadManager write there? [maybe not!]
So, we need redirect to "Downloads"

that is:

Quote
dirInternalAppStorage - DOES NOT WORK, goes to /Downloads
dirDatabase - DOES NOT WORK, goes to /Downloads
dirSharedPrefs -  DOES NOT WORK, goes to /Downloads

We will need some tests!!!

[workaround]

After download your file, copy it to "SharedPrefs"

Code: [Select]
  Self.CopyFile(Self.GetEnvironmentDirectoryPath(dirDownloads)+'/myfile.txt',
                  Self.GetEnvironmentDirectoryPath(dirSharedPrefs)+'/myfile.txt');

Here are the java "APIs" [DownloadManager.Request]

setDestinationInExternalPublicDir(Path, Filename);
setDestinationInExternalFilesDir(context, Filename , subPath)
setDestinationUri(uri)       

from docs:
Quote
Set the local destination for the downloaded file to a path within the PUBLIC EXTERNAL storage directory

So, after your tests I will can rollback the [change] commited ....

And we will need go by  the "workaround" ...

Not getting very good results, tried the new paths /data/data/.../files but cannot delete file (I need this to be sure I am using the correct file) using self.deletefile(dirInternalAppStorage, filename) like you can with say dirDownloads/dirNotifications.
Also tried creating new TEnvDirectory 'dirDocuments' ( /storage/emulated/0//Documents ) but cannot delete file there either. I must be missing another routine with this.
Decided to stick with dirDownloads for now.  :(

CopyFile will not copy to anywhere other than /Notifications, /Music etc. but FileCopy function works great!
Will copy to /data/data/com.your.packagename/files
