How to Enable Offline Notifications
Select your device type for the corresponding setup guide
iPhone Offline Notification Setup
When you first open the app, tap "Allow" for notifications.
Tip: If you missed the initial prompt, you can manually enable notification permissions in System Settings >> Notifications >> Bubble.
Samsung/Google/Sony/Motorola/Nokia Offline Notification Setup
Note: Google, Samsung, Sony, Motorola, Nokia and other international phone brands come with Google Play services pre-installed.
After logging into Bubble for the first time, when prompted to allow notifications, tap "Allow".
When using in China, you need to enable VPN access.
If push notifications are unstable, try toggling airplane mode to reconnect to the network, or go to System Settings >> Battery >> App Launch Management, find Bubble, and enable "Allow auto-start" and "Background activity".
Xiaomi/OPPO/VIVO/OnePlus Offline Notification Setup
Confirm Google Play Services is Installed
International versions and some domestic models of Xiaomi/OPPO/VIVO/OnePlus come with Google services pre-installed. Go to System Settings >> App Management >> All Apps, search for "Google Play Services" to confirm, and go to System Settings >> Accounts & Sync >> Google Basic Services to enable "Google Basic Services".
Note: If your device doesn't have it pre-installed, manually installing GMS may require unlocking the bootloader, flashing, etc., which carries risks and is not recommended.
Ensure Network Can Access Google Servers
Due to China's network environment, you may need VPN access to connect to FCM servers.
Test method: Visit https://google.com in your browser to see if you can connect.
Configure Notification Permissions and Power Saving Settings
Note: Using Xiaomi as an example, OPPO/VIVO/OnePlus settings are similar, though specific paths may vary slightly.
Enable Notification Permissions:
Xiaomi: Settings >> Notifications & Control Center >> Notification Management >> Find Bubble >> Enable "Allow notifications".
VIVO: Settings >> Notifications & Status Bar >> App Notification Management >> Find Bubble >> Enable "Allow notifications".
Allow App Auto-start:
Xiaomi: Settings >> Apps >> App Management >> Find Bubble >> Auto-start >> Select "Allow".
VIVO: Settings >> Apps >> App Management >> Find Bubble >> Permissions >> All Permissions >> Enable Auto-start switch.
Allow Background Running:
Xiaomi: Settings >> Apps >> App Management >> Find Bubble >> Battery Saver >> Select "No restrictions" or "Allow background running".
VIVO: Settings >> Battery >> Background Power Consumption Management >> Find Bubble >> Select "Allow high power consumption in background".
Disable Power Saving Restrictions: (Optional after completing the previous step)
Settings >> Battery & Performance >> Battery >> App Battery Saver >> Find Bubble >> Select "No restrictions".
Send Messages to Test
Log in/log out and log back into Bubble, kill the app, and send messages from another device to test.
Due to the instability of China's network environment, FCM push delivery rates may not be guaranteed. If you can't receive notifications reliably, try toggling airplane mode to reconnect to the network.
Huawei/Honor Offline Notification Setup
Note: Since Huawei was added to the US "Entity List" in May 2019, newer Huawei/Honor models released after that cannot have GMS framework pre-installed. You'll need to try installing the microG emulator. Some older models with GMS pre-installed can follow the Xiaomi/OPPO setup instructions.
Install MicroG Emulator
Refer to https://zhuanlan.zhihu.com/p/24574540372 to install the microG emulator as a replacement for Google Mobile Services framework.
Ensure Network Can Access Google Servers
Due to China's network environment, you may need VPN access to connect to FCM servers.
Test method: Visit https://google.com in your browser to see if you can connect.
Confirm Bubble Has Completed Service Registration
Open Bubble, register and log in (if already logged in, log out and log back in) to complete the app's push service registration with Google FCM center.
Go to System Settings >> Apps & Services >> App Management >> Find microG Services >> Open microG Settings >> Google Cloud Messaging, confirm Bubble is in the list.
