# Hyperledger SDK For Android
 **Note** - The jar file for fabric is fabric-sdk-java/target/fabric-sdk-java01.1.0-alpha.jar. This file includes all the dependendencies. This jar will work on only on API >26 since android support Java 8 from API 26 and above. To make compatible with lower version you might have to make following changes:

**1.** Java.util.Base64 class should be replaced with android Base64 package. <br />
**2.** Java.time.Instant class should be replaced with java.sql.Timestamp. +There might be other changes required as well.<br/>
