File-Component - Upload txt-File to Firebase Storage

[MrX (Nico)]

Hi,

I want to upload a created txt-Textfile to Firebase Storage, but the app shows an error:

The error-message is: “/test.txt (No such file or directory)” (see screenshot)

Of course I read the other topics in this community with regard to this, read the docs and watched many videos on Youtube and tried many other file paths, but I didn’t find a solution, which worked for that.

I read about huge problems with the file-component (sometimes you have to use the complete path, sometimes the relative path, …).

What do I have to write behind “file”, that I won’t get the error?

I hope someone can help me.

Thanks

and tried many other file paths, but I didn’t find a solution, which worked for that.

which other file paths did you try?
probably you also should set the upload path socket?

Hello, How can I upload the pictures I upload to Firebase Storage with different names? And how can I view and download images on Screen1? My blocks; [Screenshot_5]

I think Firebase Storage component uses absolute file path.

[MrX (Nico)]

It works with the absolute file path! Thanks @vknow360 and @Taifun

…but only with a permission

And this problems seems to be unsolved until now:

READ_ / WRITE_EXTERNAL_STORAGE permissions / app-Specific (Private) External Storage

@MrX

but only with a permission

And this problems seems to be unsolved until now:

You are not using private storage for your file and thereby you need permission…

[MrX (Nico)]

Later I tested it with using private storage (see link from my last post) and it needed the permission too

Or do you know any other solution to need no permission for this problem?

EFile : Only asks for permissions when required

Introduction EFile is a modified version of original File component.The only difference between File component and the extension is that the extension does not asks for write permission if you want to write to Application Specific Directory and read permission if you want to read from Application Specific Directory or Assets. Latest Version: 1 Released: 2020-06-10T18:30:00Z (UTC) Blocks [image] Documentation After File Saved Event indicating that the contents of the file have been writte…

[MrX (Nico)]

Thanks, but unfortunately that didn’t solve the problem.

The aks for permission comes again, by clicking on the “B_Upload”-Button. I don’t know if I did something wrong.

But I think…

@MrX

this problems seems to be unsolved until now

…like explained here:

READ_ / WRITE_EXTERNAL_STORAGE permissions / app-Specific (Private) External Storage

Hello especially to the developers, for several reasons I want to switch from App Inventor to Kodular. Unfortunately, Kokular also has a permission issue (READ_WRITE_EXTERNAL_STORAGE) when saving to an app-specific folder. I have already posted this issue in the App Inventor Forum, but have not received a satisfactory answer. I would like to save files in the so-called “app-specific (private) external storage”. According to Google, this does not require READ_ / WRITE_EXTERNAL STORAGE permissio…

Try one of these extensions to create the ASD:

instead of using the File component (which requires WRITE permission, even for an ASD):

[bodymindpower (Anke)]

… and you may not need to create the ASD, because the EFile extension will probably do it automatically (by .SaveFile text).

[MrX (Nico)]

Did you mean this way:

I tested it with the other extension too and without creating ASD, as you suggested in your last post, but still I need the permission

Strangely the following blocks works without any problems (and need no permission to READ the text from the txt-file):

@MrX

but still I need the permission

Try this:

instead of:

and remove the Package_Utilities comp.

[Boban (Boban Stojmenovic)]

@bodymindpower

because the EFile extension will probably do it automatically

Actually Kodular does this for you already

Since I’m unfamiliar with Firebase Storage, now the question is if Firebase Storage component and blocks such this, may trigger permission and for upload, if it is full, relative path or not???

[bodymindpower (Anke)]

@Boban

Actually Kodular does this for you already

Yes, the ASD is now always created by Kodular (don’t know how long this has been so).
But AI2 doesn’t create it.

@Boban

now the question is if Firebase Storage component and blocks such this, may trigger permission

No, see here:

The problem arises from the EFile extension (EFile.ReadFrom), which requests READ permission (even when reading from ASD): @vknow360

  }else{
    if (!hasReadAccess) {


      new Handler().post(new Runnable() {
          @Override
          public void run() {
          form.askPermission(Manifest.permission.READ_EXTERNAL_STORAGE,
              new PermissionResultHandler() {
                  @Override
                  public void HandlePermissionResponse(String permission, boolean granted) {
                      hasReadAccess = granted;
                  }
              });
          }
      });
    }

So @vknow360 has to fix that (→ read from ASD without READ permission).

Note: The file test.txt is created in the ASD without WRITE permission.

[vknow360 (Sunny Gupta)]

@bodymindpower

So @vknow360 has to fix that

Not necessary.
Since extension is open source so anyone can modify it.
I shall check it after Hackathon.

[bodymindpower (Anke)]

@vknow360

anyone can modify it

Of course, you’re right. But very few are likely to be able to adapt this so that READ permission is no longer requested when reading from an ASD.

[Boban (Boban Stojmenovic)]

I built a test app yesterday and it did not ask for permission but without Firebase Storage component

@Boban

Then show your blocks.

That saves file to private storage directoy in Internal Storage and not to asd in External Storage.
