Thank you for paying attention to my post.
No. I have no errors during compilations. App is working well excluding one case:
- during instalation appears info that app is written for older Android verion an can work wrong.
I am ignoring this info and result is positiv. Ap iss working as expected.

On the other hand when I have started with B4A (2 years ago) after instalation I had no any errers with SDK Manager.
I have noticed SDK wornings after trying to clear all foults from log panel of B4A IDE. After cleaning all unused values, files etc. , two of them are still remaining:

- Plik 'autko4.jpg' nie jest używany. (warning #15)
(file 'autko4.jpg' is not used.
- Zalecana wartość dla android: targetSdkVersion wynosi 28 lub wyższa (edytor manifestów). (warning #31)
(Suggested value of targetSdkVersion for android is 28 or higher (manifest editor).

In first case I cannot find any file 'autko4.jpj' within Files catalogue and any other place in Designer.

In second case I have started with updateing SDK manager and then wornings from my first post have appeard.
Along suggestion I have changed target SDK version in manifest editor (recently I have 16) but then app starts to make foults.
I had to come back to SDK v16 , remove app and install it again to come back to the start point.

What SDK target version is suggested by you ?
I have noticed also similar problem ( in my opinion) here:

I am using from many , many years TotalCommander.
Do you think that I ca get wrong decompressing ?

Thank you for help and wishes of a nice day for everyone.

You can usually safely ignore this as it is only a warning, not an error. It started with Android 10 (I think) and means that the target SDK of the app is earlier than that of the current Android version.

I would start again with a new SDK installation unzipped with 7-Zip. I have no idea whether Total Commander suffers the same problem as Windows built-in decompresseor. SDK Manager will work on a correctly installed SDK but should not be necessary for almost everybody.

For apps not for the Play Store I use a target SDK of 28, later ones limit file access to the internal memory. For Play Store apps you have no choice but to use SDK 30, soon to be 31.
