just updated the SDK through SDK Manager
all went ok
now when trying to run a project in debug mode I get the following
Maven artifact not found: androidx.annotation/annotation-experimental

what should i do ?

my B4A version is 10.50
SDK manager version is 3.71

it's kind of urgent as it is in the middle of work...

thanks

maybe it has something to do with access permissions ?
i used to access external memory
now i try internal
that doesn't seem to need any permission
i try to use - SaveDir = File.DirInternal
that seems to be failing when i try to access the file
is this make any sense ?

Just look at the logs

at anywheresoftware.b4a.phone.Phone$PhoneId.GetDeviceId(Phone.java:441)

You are calling the PhoneId.GetDeviceId in the Phone library.

YOU

Zeev Goldstein said:
can you tell the function name that causes the error ?

I didn´t see any project uploaded which shows the issue. HOW can we help here? NO ONE knows the code you are using except you.

Based on the error you are trying to access a device-id, Mac address for example.

Upload a small project which shows the problem.

SHAME, SHAME ON ME !!!
i apologize for wasting your time and patience

thank you so much for your patience and support

now i got a real strage issue
in release mode - all fine
in debug mode i get this "Maven artifact not found" message

Maven artifact not found: androidx.annotation/annotation-experimental

how do i fix this ?

agraham · Feb 12, 2021

I have to assume that for some reason you need this component but I do wonder why? Assuming you have correctly installed the SDK as we previously told you, open SDK Manager, Deselect All, search for 'experimental', select ONLY androidx.annotation.annotation-experimental and Install Selected.

thanks
i don't know why i need it - i first saw it today after the sdk update

did what you say and now i get this error (on both debug & release)

Hard to tell but it looks like you downloaded more things from SDK Manager than the single missing one - start again with a new SDK.

Zeev Goldstein · Feb 12, 2021

what do you mean "start again with the new sdk" ?

agraham · Feb 12, 2021

Like you did in post #6 of this thread.

Zeev Goldstein · Feb 12, 2021

yes!!
now it is all perfect
once again thank you very much

why do i need that experimental object ?
why use experimental objects at all ?
i never needed it, on 28 it is not required just the change to 29 dropped it on me...

Lello1964 · Feb 12, 2021

I have solved creating empty new folder and install sdk inside.

I wish I knew but I don't

Zeev Goldstein · Feb 12, 2021

Maybe this is for Erel to answer?

el.

unfortunately after installing the necessary SDK updates, the problem returned.
I believe there is an error that needs to be fixed by @Erel.

Oops
Anything i need to do other than change the target in the manifest?
I changed it to 30 but the app crashes now
If i return to 28 it works perfectly
Any idea?
Thanks

maybe you are missing the configuration of the path

but also you should post the error

Maven artifact not found: com.google.guava/listenablefuture (SOLVED)

Just updated the SDK through the B4A SDK Manger and now I get the "Maven artifact not found: com.google.guava/listenablefuture". I tried searching for it, and this is closest one installed: I see that others had this issue in the past - seems that updates to the SDK Manager to 3.6 fixed it...

thanks,
can you please explain?
how do i install the sdk alone ?
now that i have gone through this all - how do i fix it ?

All the SDK elements you need (usually) are in the required resources download here: https://www.b4x.com/b4a.html

That and the Android SDK Command line tools (same place) comprise the whole Android environment b4a needs.
There are a exceptions, but when you need them, you'll know enough to know how and why.

You can just delete your 'Android' folder and re-create it with Step 2 here: https://www.b4x.com/b4a.html
