Error on data writing to the connection: invalid socket

[atta_mudassar]

I am working on an android app that has direct access to mySql. I am using MyDac to connect to mySql. Problem is that the app works fine on Android 6 but gives following error on Android 7 and terminates immediately.

Project xxxxx.apk raised exception class EMySqlException with message 'Error on data writing to the connection: invalid socket'.

I tried to update sdk and am now using Android sdk 24.4.1 but still the problem is same.
Any ideas what to do?

Please specify the used full IDE version.

I am using RAD Studio XE7 update 1. And MyDac version 8.6

The issue may be due to that RAD Studio XE7 has no support for Android 7: http://docwiki.embarcadero.com/Platform ... /Main_Page
Please try to compile and run your project for Android version supported in RAD Studio XE7.
