Android Question HELP: Maven artifact not found: androidx.annotation/annotation-experimental

Zeev Goldstein · Feb 12, 2021

help...
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

Install the missing sdk with the sdkmanager. Search for "experimental"

this was only after the SDK update
before that all went smoothly

don't update, only do it when you are free.
It is my rule.

looks like the solution to your problem is reinstall the sdk and don't update it

Edit: I found this:

Found tag id where item is expected Error

follow the installation instructions:

B4A – The simple way to develop native Android apps

B4A includes all the features needed to quickly develop any type of Android app. B4A is used by tens of thousands of developers from all over the world, including companies such as NASA, HP, IBM and others.

www.b4x.com

don't update the sdk,
and if you still have your first error:

Maven artifact not found androidx.annotation/annotation-experimental

While opening my existing project on B4A 10.2, I am getting the following error on opening. I had already install B4A freshly with all new downloaded resources, updated android through sdk manager. But the problem persist. Any help will be appreciable. Thank you

Zeev Goldstein · Feb 12, 2021

OK
reinstalled and now it is working like charm
many many thanks !!!
just one last question:
is the newly installed SDK supports 29 and 30 as google demands ?

agraham · Feb 12, 2021

Yes - SDK 30 as you can see in the platforms folder.

Zeev Goldstein · Feb 12, 2021

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

agraham · Feb 12, 2021

That's not much help. Logs? Anyway Erel advises using SDK 29 for now as that is what the Play Store requires.

Zeev Goldstein · Feb 12, 2021

Ok
I'll try 29
When the app crashes there is no log
It just close down
I'll go for the 29 and try
Once again thanks

It is a great idea to HIDE the full Error.

There is NO SUCH THING like no log. If a App crashes you must be able to see this in the LOG. Maybe the unfiltered Log.

Think over if this can help us helping you....

i'm making some modifications and see what will happen

Zeev Goldstein · Feb 12, 2021

why is it working perfectly on debug ?

android.jar / targetSdkVersion / minSdkVersion

There are several versioned components that affect the compilation process and the runtime behavior of our apps. The purpose of this tutorial is to explain the differences between them and help you choose which version to use. Each Android version is mapped to an api level. You can see this...

www.b4x.com

Additional changes in Android 10 that are not related to the targetSdkVersion value:

StartActivity from a service will not work if there is no visible activity. As a workaround you can request the special "draw over apps" permission: https://www.b4x.com/android/forum/threads/draw-on-top-of-other-apps-permission.90513/
It will allow StartActivity to work.

Most of the device unique ids are not exposed. Two are available:
Advertising id: https://www.b4x.com/android/forum/threads/101050/#content
Phone.GetSettings ("android_id") - https://www.b4x.com/android/forum/threads/get-unique-id-for-user.124396/#content

PD: You should always test your app in Releasemode. In debugmode some restrictions are off.

i'm afraid i'm lost...
not sure i got what you mean

who is user 10790 ?
who created it ? who owns it ?

i'm not using a service, it is a simple application

why does it work perfectly on 28 and crash on 29 ?
what am i missing ? (looks like a lot...)

google requires 29 so i must understand how to change and what to change so i can go on 29

anything you can help ?

Zeev Goldstein · Feb 12, 2021

that's very odd

on a device with android 9 - it works
on a device with android 10 - it crashes

No it's not. From post #16 above

...

You seem to be trying to obtain an ID that is no longer available.

Zeev Goldstein · Feb 12, 2021

thanks
i don't think i do so anymore
i used to read imei but long ago i changed it
can you tell the function name that causes the error ?
