    Hi Davy! Official response from the Android team is > “usually this means that there is something wrong with code because of obfuscation + something related to java version – I’ve seen similar messages when I was working with Xamarin binding. never seen such exceptions within Android Studio. ” … We need to know a bit more information from you such as what Java SDK version and whether you are using any special toolsets such as Android Toolchain Jack https://source.android.com/source/jack.html. Anything like that about project configuration that can help us identify the problem. Best regards, Andrew

Hello andrew thanks for your answer ,

The SDK version for the compilation is 24 and I don’t use special toochain,
the program launch successful, the bug is when I use the layout editor , in android studio with constraintLayout.

Hello,
We are evaluating the SciChart Android v1.2.0 with SDK version 25.

We get the same compilation error as above (java.lang.VerifyError: Expecting a stackmap frame at branch target 111).

Do you have any revision that supports SDK version 25 or an alternative solution to solve this compilation error ?

Thank you.
