Hi MAF Experts,
I'm trying to implement Chat Heads in MAF, I have added android.permission.SYSTEM_ALERT_WINDOW in Android-Manifest.template.xml under jdeveloper/jdev/extensions/oracle.maf/Android/Oracle_ADFmf_Framework.zip
However, I have not found a way to create Service Class in MAF

Last but not least, I have to start the Service class

Please refer to the link below for Android Native App Chat-Heads tutorials.

Any suggestion?
Best Regards,
Hendry
