Polar SDK searchForDevice() doesn't work on phones running Android 10/EMUI (Huawei, Xiaomi) #446

Describe the bug

Polar bands cannot be discovered when using searchForDevice() on Huawei/Xiaomi phones (EMUI 12, Android 10).This seems to be similar to #330.

We have the same issue running Huawei P30 Lite and Android 10 (EMUI 12). Interestingly this issue has been introduced in one of the OEM software updates. I don't have the exact build number of the previously working EMUI version, but after updating overnight to 12.0.0.262 the Polar SDK stopped reporting devices.

We are using ACCESS_BACKGROUND_LOCATION permission, but it doesn't help.

How to Reproduce

Polar SDK com.github.polarofficial:polar-ble-sdk:5.5.0

searchDisposable = PolarBleApiDefaultImpl.defaultImplementation(
    applicationContext,
    PolarBleApi.PolarBleSdkFeature.values().toSet()
)
    .searchForDevice()
    .subscribe(
        { data ->
            Logger.info(TAG, "Received ${data.deviceId} ${data.isConnectable} ${data.rssi} ${data.name}")
            set.add(DeviceConnection(
                BtConnectionStatus.Unknown,
                data.deviceId,
                data.name,
                data.address,
                data.isConnectable,
            ))
            Handler(Looper.getMainLooper()).post {
                eventSink.success(
                    "[${set.joinToString(",")}]"
                )
            }
        },
        {
                error ->
            Logger.error(TAG, "Error occurred when searching for Polar devices", error)
        }
    )

Expected behavior

Scan should return Polar devices or throw error if there's something missing e.g. in terms of permissions.

Some updates

I tested using Polar Flow, and the app checks for "system location" and navigated me to this screen to toggle on "Access my location". It was off before.

Now after enabling this it works!
