So what did you change from V1 to V2? Did you edit your DB? did you deploy your V1 form a different laptop than the one you are using now? What is the error given after this incompatible error. Does it explain why its not compatible? – Kapil G Aug 07 '17 at 07:41

Getting this message "Installation failed with message INSTALL_FAILED_UPDATE_INCOMPATIBLE. It is possible that this issue is resolved by uninstalling an existing version of the apk if it is present, and then re-installing." – Vijeth Adhyapak Aug 07 '17 at 08:01

Just remove the old one from your device first and then run again.

this will help in installation but won't tell what is the issue to OP for preventing it next time. – Kapil G Aug 07 '17 at 07:40

Any other solution without uninstalling the previous version. I need to retain the data from the previous version. – Vijeth Adhyapak Aug 07 '17 at 07:41

Try changing the version code to a higher number. Let me know so I can update my answer. – Jisu Hong Aug 07 '17 at 08:17
