[jira] [Comment Edited] (KAFKA-7025) Android client support
[ https://issues.apache.org/jira/browse/KAFKA-7025?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17390977#comment-17390977 ]

Hm, compiler does not specify file where it used. But if i try to find by code, i can found it:
[https://github.com/apache/kafka/blob/99b9b3e84f4e98c3f07714e1de6a139a004cbc5b/clients/src/main/java/org/apache/kafka/common/utils/ByteBufferUnmapper.java#L81]
So i think if remove this call, it will able compile, with old android versions.
The main thing is not just not to use it, but to remove it from the code, because all files, regardless of use, are converted to DEX ... and when the compiler encounters this method, a problem occurs.
Will try last version....

> Project: Kafka
> Issue Type: Bug
> Components: clients

> Adding kafka-clients:1.0.0 (also 1.0.1 and 1.1.0) to an Android project would make the compilation fail: com.android.tools.r8.ApiLevelException: MethodHandle.invoke and MethodHandle.invokeExact are only supported starting with Android O (--min-api 26)
>
> Would it be possible to make the kafka-clients backward compatible with reasonable Android API (say, 4.4.x) please?
