When I am see the whatsapp, hike and others notification app he will always run in background thread but my app is not running always in background. So may be this reason be also. I am recently working on android please help me.Thanks in advance!

Answer 1

I faced similar issue with Redmi-2. There is no problem in the code but it is due to Custom UI provided by the Manufacturer like MIUI 6. So to enable GCM notifications

Go to Security App >> Tap on permissions >> Tap on Auto Start and enable auto start for your App.

Answer 2

There are two major reasons for that

1 - Some devices does not allow you to run a service on background like redmi-2 ( almost on all xiaomi device ). Even whats app could not work properly on them unless user allow them by going to Security App >> Tap on permissions >> Tap on Auto Start and enable auto start for whatsapp etc. In this case all you can do is to show the details of this to user on application start up. And open that screen and guide user ( if possible ) like clean master.

2- Second reason is that it didn't work on one of those phone whose Google Play Services app wasn't installed correctly(and its essential for GCM). You can not do anything on these devices also. The only thing you can do in this case is just show some message to user about this.

So from my experience there always be a number of users(but very small percentage) who wont receive GCM push.

Answer 3

There is concept of whitelisting in Xiaomi's phone. So, if you put log in onReceive of gcm, you will notice that gcm is receiving but it's not processing further. Its cause your app is not whitelisted.

Xiaomi for security purposes disables the Notification for each Application. Follow these steps to receive messages in background once they quit the app using cleaner.

• Enable Autostart
• Enable Floating and Lock Screen Notification

Enable AutoStart

• Open Security App.
• Got to Permissions, then Click on Auto Start Management.
• Add/Enable auto start apps (e.g. Whatsapp).

Enable Floating and Lock Screen Notification

• Open Settings App.
• Click on Notifications, then click on Manage Notifications.
• Tap on the App which you are looking for (e.g. WhatsApp).
• Enable Show in notification shade / Show on lockscreen and in drop down option.
