Is it a security issue?

• No

What did you do?

• Integrating LINE Login.

What did you expect?

• Do not appear 'deprecated' warning

What happened actually?

  • https://developers.line.biz/en/docs/line-login-sdks/android-sdk/integrate-line-login/#handling-login-result
• But 'onActivityResult' is deprecated API.
• The android development environment no longer recommends that developers call the onActivityResult API.

Your environment?
