GCM features is added with the Google Services. While developing android application to use the GCM the device require to have Google APK installed.
And I heard that some of the devices not having the Play Store APK or there is no support for GCM. The devices like Amazon Fire phone, xiaomi and all.
I want to develop an app to support all the user. Is not like the user having installed Play Store APK can use our application.
I thought of using pubnub. I don't know whether this is an right alternative. Because I am not finding any other way to overcome this issue.
Please help me on this.
Thanks in advance.
