Can I use Apache-Flink for Android API-Level < 26?

[Alexander Borgschulze]

I am trying to use Apache-Flink in my Android-Project with "minSdkVersion 24".

Unfortunately, the following code causes an error:

   

 

    val env: StreamExecutionEnvironment = LocalStreamEnvironment.getExecutionEnvironment()
    env.streamTimeCharacteristic = TimeCharacteristic.ProcessingTime
    val integerStream: DataStream<Int> = env.fromCollection(mutableListOf(1,2,3,4,5))
    
    integerStream.print()
    env.execute()

 

java.lang.NoClassDefFoundError: Failed resolution of: Ljava/time/Instant;
        at org.apache.flink.api.common.typeinfo.BasicTypeInfo.<clinit>(BasicTypeInfo.java:89)
        at org.apache.flink.api.common.typeinfo.BasicTypeInfo.getInfoFor(BasicTypeInfo.java:214)

        at org.apache.flink.streaming.api.environment.StreamExecutionEnvironment.fromCollection(StreamExecutionEnvironment.java:782)

 

 

 

The java.time API was introduced in API Level 26. So is it impossible to run Flink on older Android-Verions?
