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

[cambol]

I had reinstall SDK for SDK Version:30

and my android:targetSdkVersion="30"

But it show error below .

In this B4A project , I use RuntimePermissions Library Version : 1.12

I use for rp.CheckAndRequest(rp.PERMISSION_WRITE_EXTERNAL_STORAGE)

If I remove RuntimePermissions in library , It will not show this error .

Delete your Android SDK and download a new one: https://www.b4x.com/b4a.html

I have done this already , In my b4A project , compile is OK . but in my another B4A project
I use RuntimePermissions Library Version : 1.12

I use for rp.CheckAndRequest(rp.PERMISSION_WRITE_EXTERNAL_STORAGE)

If I remove RuntimePermissions in library , It will not show this error .



I guest It something wrong with RuntimePermissions in .PERMISSION_WRITE_EXTERNAL_STORAGE

There is nothing wrong with B4A 11.50, RuntimePermissions 1.12 and the latest SDK in my projects. Have you done anything other than follow Erel's instructions exactly? Use 7-Zip to unzip the SDK archives and do not run SDK Manager.
