Quickstart-android: I still get the FCM message well on Android P

[HanSeungBeom]

Step 1: Describe your environment

• Android device: Galaxy S10
• Android OS version: Android 9.0
• Google Play Services version: 12451000
• Firebase/Play Services SDK version: 17.3.4

Step 2: Describe the problem:

Android Document Guide

The above information is contained in the Android development document.
for my testing, I changed the settings(app>battery>background restriction on), sent a push message, with device unplugged.
But the message was well received. Has this feature been applied yet?

my app targetsdkversion is 28.

Observed Results:

I sent push message to the test device, and received.

Expected Results:

I expected not to receive a push message because the test phone's os 9.0 and app>battery>background restriction on.

Is there anything I missed?

@HanSeungBeom that's a good question!

@kroikie does this apply to both notification and data messages? Also is it possible that an OEM could override this behavior?

[kroikie]

@HanSeungBeom I did checking around and that restriction is not yet implemented. It will be turned on in an up coming update. I don't have a timeline for this update however I would recommend that you operate as if it were already implemented to avoid unexpected behavior in the future. I have also softened the language in the docs since the FCM restriction is not yet in operation, thanks for pointing that out.
