Android notification does not appear in the android device notification center if the android:targetSdkVersion="26"

[mg4u]

Hi,
I develop an application using ti sdk-version=7.2.0 and everything works fine.
But if I set android:targetSdkVersion="26" in the tiapp.xml android section, the notification does not appear in the device notification center.
<uses-sdk android:minSdkVersion="20" android:targetSdkVersion="26"/>

Note that the notification appears in the log

var gcm = require("nl.vanvianen.android.gcm");
function callback(e) {
    console.log("callback notification=> \n "+JSON.stringify(e)) // <<<<<< DISPLAY THE NOTIFICATION
}
[........]

Is the issue about setting channel?, if so how can I set the channel?
Any help will be appreciated.
