Hello to all,
I receive this error:

copy fichier

I receive the error on App installed on: Android 5.0.1, Android 6.0 and Android 8.0.
The "Manifest" of my App is:

android.jar / targetSdkVersion / minSdkVersion
RuntimePermissions

Additionally you should update to B4A 8+ as your app will not work correctly under Android 8 without this version.

Android JAR is: C:\Android\platforms\android-26\android.jar

- Update to B4A 8+

Setup a new SDK using the Build in SDK Manager.
Watch the Video. Start with a blank folder for the new SDK.

Hello DonManfred,
I update to B4A 8.3, but I have the same error on Android 5.0.1 and Android 6.0

Did you setup a new SDK? What is the path of the android.jar you defined in Tools-Configure paths?
Did you setup your app to use RuntimePermissions?
You are not providing enough informations.
Post the new FULL Error.

Hello DonManfred,
>Did you setup a new SDK? What is the path of the android.jar you defined in Tools-Configure paths?
my path to android.jar is: C:\Android\platforms\android-26\android.jar
>Did you setup your app to use RuntimePermissions
is it enough the Manifest content? If not: please where I need to see?

Thanks
