[Antonio_Bruno (Antonio)]

Hi,
i need to know if a specified file is present in the asset directory like the example below. The file is present but the result is always false.
I have tried whit di prefix “\” or “//” but the result is the same.
Can anyone help me?

You are the only one who can upload assets into your apk.
So why do you need to check if it exists?
Sense?

If you did not added any into your assets then there are none

Hi dora_paz,
in Kompanion your solution work fine but when a create apk and test fileexist i obtain FALSE
I tried to use a if condition where with develop=true use “/Makeroid/assets/1.jpg” while when develop=false use “//1.jpg” but the result is always false.
Any suggestion?

[Free] Extension. Terminal. Using LINUX commands. Copy files from assets

I have updated my com.KIO4_Terminal.aix extension with more functions with the assets. For these blocks to work, the app must be installed. [terminal16K] ListAllAssets, get a list from files in assets. CopyAllAssets, copy all user files from assets to dir in SdCard. CopyAllAssetsX, copy all files from assets to dir in SdCard. CopyFromAssets, copy a file from assets to dir in SdCard. PathFileAssets, get path file in assets when app is installed. You can download extension from: http://ki…

there is a block: ListAllAssets that gets a list of assets files when the app is installed.

@dora_paz

Try this /Makeroid/assets/your_file

this will work only in the companion app, but not anymore after building the app

the file extension offers the method FileListFromAssets

Note: in Kodular this works only after building the app, see here why

I tried to use a if condition where with develop=true use “/Makeroid/assets/1.jpg” while when develop=false use “//1.jpg” but the result is always false.

Yes, this is also a bug with the File component. This path doesn’t work:

there is no path to access the assets so far.

I reported this also several times.
See here (point 4):

File path for unzip file component

It’s really hard to get it working, because there are several issues with the File component: Sometimes the full path and sometimes the relative is used (see blocks below) WRITE permission is not queried automatically (only READ), so you have to ask manually for WRITE permission. Permission granted is not triggered when the app starts for the first time, so you have to reload the screen. Moreover: the File component can not access the assets with the APK (works only with companion). To chec…

@Mika is / was working on it:

Issue in create file in mobile (ex:- test.txt)

Thanks! On this occasion: another bug of the File component is that it is not possible to copy a file from the assets to the external storage (with the compiled app / APK, Companion works). I have also reported this bug many times. @Mika [grafik]

With the next release it should be possible too to check if a asset file exist.
No matter if companion or real apk.

It will work then with two // (slashes) at the start to tell the code it’s a asset file check.

tried but not all file are listed:

[juananton1991 (Juan Antonio)]

What is the extension of the files that are not listed?

@Antonio_Bruno

estion?

That block works when the app is installed.
If you want to see the list of files in assets while you are in emulation (COMPANION), check:
http://kio4.com/appinventor/278_extension_shell.htm

Terminal.Run — commandLine: ls -al /mnt/sdcard/Makeroid/assets/

or

ls /mnt/sdcard/Makeroid/assets/

[Antonio_Bruno (Antonio)]

@Antonio_Bruno

/Makeroid/assets/

for now i have solved with dora-paz solution when the app run in companion
and [juananton1991] solution when the app is installed.

Thank you
