Can not receive notification on Android 4.4.2 devices.

I cann't receive push notification on android 4.4.2 devices when i send data in below format.
{
"to":"/topics/foobar",
"data": {
"type":"MEASURE_CHANGE",
"custom_notification": {
"body": "Hello",
"title": "this is title",
"big_text": "i am large, i am large, i am large, i am large, i am large, i am large, i am large, i am large, i am large, i am large, i am large, i am large, i am large, i am large, i am large, i am large, i am large, i am large, i am large, i am large, i am large, i am large, i am large, i am large, i am large, i am large, i am large",
"color":"#00ACD4",
"group": "GROUP",
"priority":"high",
"show_in_foreground": true
}
}
}

but it is working fine on Android 6.0.1. Is there any way to solve this issue??
